J Gene Med 2021 Feb 3:e3320. Epub 2021 Feb 3.

Cellular and Molecular Biology Research Center, Health Research Institute, Babol University of Medical Sciences, Babol, Iran.

Background: MicroRNAs (miRs), which are stable in the blood, comprise small non-coding RNAs that regulate gene expression. They have important roles in almost all biological pathways, especially in cancer-relevant processes, and have an abnormal expression in breast cancer. In recent studies, the aberrant expression level of various microRNAs has been demonstrated in human cancer. In the present study, the status of serum microRNA-210-3p and microRNA-660-5p expression levels in breast cancer patients was determined compared to healthy controls.

Methods: Serum samples were collected from 40 newly diagnosed breast cancer patients and 40 healthy controls. A real-time quantitative polymerase chain reaction was utilized to detect the expression levels of these microRNAs. Data analysis was conducted with p < 0.05 being considered statistically significant.

Results: The data obtained showed that serum levels of miR-660-5p and miR-210-3p were significantly up-regulated in breast cancer patients compared to healthy controls (p < 0.001 and p = 0.001, respectively). In addition, significant up-regulation was observed in the early stage (in situ, stage I and II) of breast cancer patients (n = 25) compared to healthy (n = 40) controls (p < 0.001 and p < 0.05, respectively). Receiver-operating characteristic curve analysis indicated that the serum miR-660-5p and miR-210-3p levels have reasonable sensitivity (79% and 68%) and specificity (61% and 51%) for the detection of breast cancer patients (area under the receiver-operating curve = 0.774 and 0.716, respectively).

Conclusions: Although the results show a reasonable diagnostic accuracy of these microRNAs for detection of breast cancer in this small and preliminary study, further large-scale studies are essential to confirm the presented results.

Competing endogenous RNAs (CeRNAs): Novel network in Neurological Disorders.

Curr Med Chem 2020 Dec 17. Epub 2020 Dec 17.

Cellular and Molecular Biology Research Center, Health Research Institute, Babol University of Medical Sciences, Babol. Iran.

Neurological Disorders (NDs) comprise a broad range of diseases affecting both central and peripheral nervous systems. These complex multifactorial diseases have a high rate of mortality all over the world, particularly in aged people. Today, new evidence drove our attention to the notable role of noncoding RNAs (ncRNAs) in the progression of NDs. Remarkably, recent studies showed that there are close communication networks among RNA transcripts such as mRNAs, long non-coding RNAs (lncRNAs), circular RNAs (circRNAs), and pseudogenes for regulating each other's expression through competing for shared sequences in microRNAs (miRs). This concept is a new area of ongoing research recognized as competing endogenous RNA (ceRNA) hypothesis. CeRNAs are novel regulatory molecules in a wide range of biological stages and pathological contexts. Indeed, the disruption of ceRNA networks (ceRNETs) may affect neural development genes and induce neuropathological changes leading to the development of NDs. Because of this, identifying the correlation of ceRNETs with NDs will open a new window for expanding our knowledge about this field of science, as well as creating novel roads for developing specific diagnostic biomarkers for NDs management. Owing to these unique features, exploring the exact role of ceRNAs is a hot topic in NDs investigations. Hence, in this review, we will summarize the evidence supporting ceRNETs in the regulation of NDs-related gene expression.

Evaluation of Salivary and Serum Total Antioxidant Capacity and Lipid Peroxidation in Postmenopausal Women.

Int J Dent 2020 17;2020:8860467. Epub 2020 Nov 17.

Oral Health Research Center, Babol University of Medical Sciences, Babol, Iran.

Objective: In menopause, reduction of estrogen hormone affects oxidative stress process in serum. Oxidative stress in saliva plays a significant role in the pathogenesis of oral diseases. The aim of this study was to investigate the total antioxidant capacity and lipid peroxidation in the serum and saliva of premenopausal and postmenopausal women.

Methods: In this case control study, 50 postmenopausal women (case group) and 48 premenopausal women (control group) were selected. The unstimulated whole saliva and serum of the postmenopausal and premenopausal women were collected. The total antioxidant capacity (TAC) of the saliva and serum was measured by ferric reducing antioxidant power (FRAP). Also, malondialdehyde (MDA) was measured by thiobarbituric acid reactive substance (TBARS) method for serum and saliva. Then, the obtained data were analyzed by SPSS 17, whereby Mann-Whitney test and Spearman's correlation test were used. < 0.05 was considered statistically significant.

Results: The postmenopausal group had significantly lower mean serum TAC and higher mean serum MDA than the control group ( < 0 < 001 and < 0.01, respectively). The mean salivary TAC and MDA, however, did not differ significantly between the case and control group ( = 0.64 and = 0.08, respectively).

Conclusion: In postmenopausal women, with elevation of serum MDA and reduction of serum TAC, the extent of serum oxidative stress grows, but MDA and TAC levels of saliva do not change.

Evaluation of the plasma level of long non-coding RNA PCAT1 in prostatic hyperplasia and newly diagnosed prostate cancer patients.

J Gene Med 2020 10 6;22(10):e3239. Epub 2020 Jul 6.

Cellular and Molecular Biology Research Center, Health Research Institute, Babol University of Medical Sciences, Babol, Iran.

Background: Prostate cancer (PCa) is generally detected by prostate-specific antigen (PSA) as one of the most widely applied tumor markers over decades for its high sensitivity. Nevertheless, it causes overtreatment or an unnecessary biopsy because of its limited specificity. PCa-associated ncRNA transcript 1 (PCAT1), the newly identified long non-coding RNA (lncRNA) has been reported to associate with the progress of PCa. In vitro studies proposed that PCAT-1 may be an appealing candidate for diagnostic accuracy improvement with regard to its notable overexpression in PCa cells. The present study aimed to evaluate the diagnostic potential of the plasma PCAT1 expression levels in PCa patients in comparison to benign prostatic hyperplasia (BPH) patients and healthy controls.

Methods: The plasma lncRNA PCAT1 level was measured by a real-time quantitative reverse transcriptase-polymerase chain reaction in 40 men newly diagnosed with PCa, 20 patients with BPH and 20 healthy subjects. The results were analyzed statistically using SPSS, version 25 (IBM Corp., Armonk, NY, USA).

Results: The expression of PCAT1 was significantly higher in healthy subjects compared to BPH patients (p = 0.03). The diagnostic accuracy of the plasma lncRNA PCAT-1 for discrimination of the healthy subjects than BPH patients was reasonable (area under the receiver operating characteristic curve = 0.799; sensitivity = 71%; specificity = 74%; negative predictive value = 74%; positive predictive value = 71%).

Conclusions: It appears that the plasma levels of PCAT1 expression have reasonable diagnostic accuracy for the discrimination of healthy individuals compared to those with BPH, although no significant difference of PCAT1 expression levels was observed in comparisons between the PCa with BPH and normal groups.

Effect of supportive counseling on pregnancy-specific stress, general stress, and prenatal health behaviors: A multicenter randomized controlled trial.

Patient Educ Couns 2020 11 5;103(11):2297-2304. Epub 2020 May 5.

Social Determinants of Health Research Center, Health Research Institute, Babol University of Medical Sciences, Babol, Iran. Electronic address:

Objective: The aim of this study was to investigate the effects of group supportive counseling (SC) on pregnancy-specific stress, general stress, and healthy behavior of pregnant women.

Methods: This randomized controlled trial study was conducted on 80 pregnant women in two groups; SC for six sessions, once a week for two hours (n = 40), and antenatal usual care (AUC) (n = 40). All Participants completed questionnaires measuring pregnancy-specific stress, state anxiety, prenatal health behaviors, perceived stress, and provided a saliva sample for measurement of cortisol at pre-intervention and 6-week post-intervention.

Results: The post-intervention results indicated that the outcome scores decreased more significantly in group SC than in the AUC for total NuPDQ, for state-anxiety, for PSS-14, and for unhealthy behaviors with a large effect size. Also, healthy behaviors were promoted more significantly in SC group than in AUC. However, salivary cortisol levels did not differ between group SC and AUC groups.

Conclusion: Group supportive counselling can promote pregnancy stress and healthy behaviors.

Practice Implications: Addition of supportive counseling to prenatal usual care may be suggested for pregnant women with any gestational age who seek methods for improving pregnancy stress and healthy behaviors.

Interleukin 10, lipid profile, vitamin D, selenium, metabolic syndrome, and serum antioxidant capacity in elderly people with and without cardiovascular disease: Amirkola health and ageing project cohort-based study.

ARYA Atheroscler 2019 Sep;15(5):233-240

Associate Professor, Cellular and Molecular Biology Research Center, Health Research Institute, Babol University of Medical Sciences, Babol, Iran.

Background: The age-related autoinflammation-mediated atherosclerosis is associated with some immunological, nutritional, and metabolic parameters and redox status. Here, we evaluated the association of circulatory interleukin 10 (IL-10) levels with lipid profile, some nutrients, and total anti-oxidant capacity in elderly people who presented cardiovascular disease (CVD) with or without metabolic syndrome (MetS) and in healthy subjects.

Methods: In this cross-sectional case-control study, 258 sera prepared from elderly people (144 healthy and 114 patient subjects) who participated in a community-based study, the Amirkola Health and Ageing Project (AHAP), were analyzed for IL-10, lipid profile, vitamin D, selenium (Se), antioxidant capacity, and MetS.

Results: Compared to patients, the healthy subjects exhibited higher levels of circulatory IL-10 among individuals with detectable serum IL-10 (P = 0.036). However, this difference was not observed when total subjects from both groups were compared, since more than 90% of those people were IL-10-negative. Se, vitamin D, and antioxidant levels were similar in both groups. There was a negative association between IL-10 and body mass index (BMI) (P < 0.050) and an equivocal association with vitamin D levels, whereas the association between IL-10 and other indicated variables was not significant. Significant association was observed between MetS and CVD prevalence (P < 0.001). There was a positive correlation between Se and total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), and triglyceride (TG) (P < 0.010) in healthy subjects and with TC in patients (P < 0.050).

Conclusion: A major proportion of elderly people were serum IL-10-negative, whereas independently to IL-10, MetS was most common in patients with CVD. Weight loss may have the potential to increase IL-10 levels in the elderly.

Since 2000, many countries have achieved considerable success in improving child survival, but localized progress remains unclear. To inform efforts towards United Nations Sustainable Development Goal 3.2-to end preventable child deaths by 2030-we need consistently estimated data at the subnational level regarding child mortality rates and trends. Here we quantified, for the period 2000-2017, the subnational variation in mortality rates and number of deaths of neonates, infants and children under 5 years of age within 99 low- and middle-income countries using a geostatistical survival model. We estimated that 32% of children under 5 in these countries lived in districts that had attained rates of 25 or fewer child deaths per 1,000 live births by 2017, and that 58% of child deaths between 2000 and 2017 in these countries could have been averted in the absence of geographical inequality. This study enables the identification of high-mortality clusters, patterns of progress and geographical inequalities to inform appropriate investments and implementations that will help to improve the health of all populations.

The value of mRNA expression of S100A8 and S100A9 as blood-based biomarkers of inflammatory bowel disease.

Arab J Gastroenterol 2019 Sep 25;20(3):135-140. Epub 2019 Sep 25.

Gastroenterology and Liver Diseases Research Center, Research Institute for Gastroenterology and Liver Diseases, Shahid Beheshti University of Medical Sciences, Tehran, Iran.

Background And Study Aims: Non-invasive biomarkers of inflammatory bowel diseases (IBD) are of critical importance. Here, we evaluated the S100A8 and S100A9 mRNA expression, as the heterodimers of calprotectin, in the blood leucocytes of IBD patients to find how their expression associates with the disease characteristics.

Patients And Methods: In this cross-sectional study, 59 IBD patients and 30 healthy subjects were included. The flare and remission phases of disease were identified in 46 and 13 patients, respectively. Blood leucocytes were isolated, and the S100A8 and S100A9 mRNA expression were evaluated in the isolated leucocytes using relative quantification real-time PCR.

Results: The mean S100A8 and S100A9 mRNA expression were significantly higher in IBD patients than in the controls (p = 0.03 and p = 0.02, respectively). The mean S100A8 and S100A9 mRNA expression were significantly higher in the flare phase of the disease compared with the remission phase (p = 0.01 and p = 0.007, respectively). S100A8 distinguished IBD patients from controls with the sensitivity and specificity of 73% and 64%, and flare phase of disease from remission with the sensitivity and specificity of 67% and 62%. On the other hand, S100A9 distinguished IBD patients from controls with the sensitivity and specificity of 81% and 70%, and flare phase of disease from remission with the sensitivity and specificity of 68% and 64%.

Conclusion: The S100A8 and S100A9 mRNA are differentially expressed in blood leucocytes of IBD patients compared to healthy controls as well as active versus quiescent disease. Thus, they can be potentially used as a blood-based biomarker in the monitoring of IBD.

Importance: Cancer and other noncommunicable diseases (NCDs) are now widely recognized as a threat to global development. The latest United Nations high-level meeting on NCDs reaffirmed this observation and also highlighted the slow progress in meeting the 2011 Political Declaration on the Prevention and Control of Noncommunicable Diseases and the third Sustainable Development Goal. Lack of situational analyses, priority setting, and budgeting have been identified as major obstacles in achieving these goals. All of these have in common that they require information on the local cancer epidemiology. The Global Burden of Disease (GBD) study is uniquely poised to provide these crucial data.

Objective: To describe cancer burden for 29 cancer groups in 195 countries from 1990 through 2017 to provide data needed for cancer control planning.

Evidence Review: We used the GBD study estimation methods to describe cancer incidence, mortality, years lived with disability, years of life lost, and disability-adjusted life-years (DALYs). Results are presented at the national level as well as by Socio-demographic Index (SDI), a composite indicator of income, educational attainment, and total fertility rate. We also analyzed the influence of the epidemiological vs the demographic transition on cancer incidence.

Findings: In 2017, there were 24.5 million incident cancer cases worldwide (16.8 million without nonmelanoma skin cancer [NMSC]) and 9.6 million cancer deaths. The majority of cancer DALYs came from years of life lost (97%), and only 3% came from years lived with disability. The odds of developing cancer were the lowest in the low SDI quintile (1 in 7) and the highest in the high SDI quintile (1 in 2) for both sexes. In 2017, the most common incident cancers in men were NMSC (4.3 million incident cases); tracheal, bronchus, and lung (TBL) cancer (1.5 million incident cases); and prostate cancer (1.3 million incident cases). The most common causes of cancer deaths and DALYs for men were TBL cancer (1.3 million deaths and 28.4 million DALYs), liver cancer (572 000 deaths and 15.2 million DALYs), and stomach cancer (542 000 deaths and 12.2 million DALYs). For women in 2017, the most common incident cancers were NMSC (3.3 million incident cases), breast cancer (1.9 million incident cases), and colorectal cancer (819 000 incident cases). The leading causes of cancer deaths and DALYs for women were breast cancer (601 000 deaths and 17.4 million DALYs), TBL cancer (596 000 deaths and 12.6 million DALYs), and colorectal cancer (414 000 deaths and 8.3 million DALYs).

Conclusions And Relevance: The national epidemiological profiles of cancer burden in the GBD study show large heterogeneities, which are a reflection of different exposures to risk factors, economic settings, lifestyles, and access to care and screening. The GBD study can be used by policy makers and other stakeholders to develop and improve national and local cancer control in order to achieve the global targets and improve equity in cancer care.

Fingolimod (FTY720) improves the functional recovery and myelin preservation of the optic pathway in focal demyelination model of rat optic chiasm.

Brain Res Bull 2019 11 20;153:109-121. Epub 2019 Aug 20.

Cellular and Molecular Biology Research Center, Health Research Institute, Babol University of Medical Sciences, Babol, Iran; Department of Medical Microbiology, Faculty of Medicine, Babol University of Medical Sciences, Babol, Iran.

It has been shown that fingolimod (FTY720) possesses beneficial effects on remyelination in the central nervous system (CNS). In this study, the effects of FTY720 and sodium valproate (VPA) as histone deacetylase inhibitor (HDAC) on the conductivity of visual signals, extent of demyelination area, glial activation, and expression levels of HDAC1and S1PR1 have been evaluated in the optic chiasm of lysolecithin (LPC)-induced demyelination model. In order to produce this demyelination model, LPC (1%, 2 μL) was injected into the rat optic chiasm. Latency of visual waves was measured by visual evoked potential (VEP) recording. The extent of demyelination area and level of glial activation were assessed using immunostaining. Gene expression analysis was performed to evaluate the expression levels of HDAC1, S1PR1, Olig2, and MBP in the optic chiasm. Analysis of electrophysiological data showed that LPC administration increased the latency of visual signals. FTY720 improved the functional recovery of the visual pathway and reduced the level of glial activation in the optic chiasm. FTY720 enhanced myelin repair and up-regulated the expression levels of Olig2 and MBP. Additionally, the expression levels of HDAC1 and S1PR1 were significantly reduced in animals treated with FTY720. In contrast to FTY720 treated animals, administration of VPA could not significantly improve the functional recovery of optic pathway following LPC injection. Cumulatively, the results of the present study demonstrate that FTY720 application improves the functional recovery of the optic pathway by reducing demyelination levels, amelioration of glial activation, and down-regulating of S1PR1 and HDAC1.

Diagnostic accuracy of glycoproteins in the assessment of liver fibrosis: A comparison between laminin, fibronectin, and hyaluronic acid.

Turk J Gastroenterol 2019 Jun;30(6):524-531

Department of Clinical Biochemistry, Babol University of Medical Sciences, Babol, Iran.

Background/aims: Liver fibrosis is a chronic liver injury affecting numerous individuals in the world, and efforts have been exercised for introducing a non-invasive method to evaluate the stages of liver fibrosis, which can be used instead of invasive methods, such as a liver biopsy. Various glycoproteins have been suggested by many investigators as indicators of liver fibrosis. This study aimed to compare the diagnostic accuracy of serum laminin, fibronectin, and hyaluronic acid levels in the assessment of liver fibrosis for discriminating patients from healthy subjects.

Materials And Methods: We searched the English language literature to identify relevant studies regarding the role of glycoproteins in the assessment of liver fibrosis, using the following electronic databases: Medline, PubMed central, web of knowledge (ISI), Scopus, Google scholar, Springer, and Science Direct from 1981 to 2016. The key words used for searching were "glycoproteins", "laminin", "hyaluronic acid", "fibronectin", "diagnostic accuracy", "assessment", "liver fibrosis", "cirrhosis", "liver biopsy", "grading", and "staging". The statistical data relevant for the diagnostic accuracy were extracted and analyzed using the summary receiver operating characteristic curves.

Results: The diagnostic accuracy among the glycoproteins involved in this study were compared, and the area under curves for serum levels of laminin, hyaluronic acid, and fibronectin, as indicators of diagnostic accuracy, were 0.89, 0.82, and 0.73, respectively.

Conclusion: It can be concluded that when liver biopsy is contraindicated, the serum levels of laminin, hyaluronic acid, and fibronectin can be considered screening tests as well as additional clinically useful tools for the evaluation of liver fibrosis.

Cancer is the leading cause of death all over the world and chemotherapy is an important approach to fight cancer, however, there are many obstacles against successful cancer chemotherapy such as development of multidrug resistance, poor solubility of chemotherapeutic agents and adverse side effects to healthy tissues. An important strategy to overcome these obstacles, is the use of nanotechnology. In recent years, natural polymers such as cellulose and its nanoform structure, nanocrystalline cellulose (NCC), have attracted the interest of researchers in the field of nanotechnology and specially drug delivery systems, due to biocompatibility and biodegradability of NCC. Cellulose is the most abundant natural biopolymer and changes to NCC by several chemical and mechanical methods. In this review, we mainly focus on the methods for production of NCC, physicochemical properties and medical applications of NCC (e.g. regenerative medicine, replacement of vascular grafts, tissue engineering, anti-bacterial/anti-viral applications, diagnosis and biosensing) with a special emphasize on drug delivery systems.

The roles of FGF21 in atherosclerosis pathogenesis.

Rev Endocr Metab Disord 2019 03;20(1):103-114

Aging Research Institute, Tabriz University of Medical Sciences, Tabriz, Iran.

FGF21 is a peptide hormone that regulates homeostasis of lipid and glucose as well as energy metabolism. It is mainly expressed and secreted in liver and adipose tissues, and it is expressed in lower amounts in the aorta. Recent clinical and preclinical studies indicate increased serum FGF21 levels in atherosclerosis patients. Also, FGF21 therapy has been reported to reduce the initiation and progression of atherosclerosis in animal models and in vitro studies. Moreover, growing evidence indicates that administration of exogenous FGF21 induces anti-atherosclerotic effects, because of its ability to reduce lipid profile, alleviation of oxidative stress, inflammation, and apoptosis. Therefore, FGF21 can not only be considered as a biomarker for predicting atherosclerosis, but also induce protective effects against atherosclerosis. Besides, serum levels of FGF21 increase in various diseases including in diabetes mellitus, hypertension, and obesity, which may be related to initiating and exacerbating atherosclerosis. On the other hand, FGF21 therapy significantly improves lipid profiles, and reduces vascular inflammation and oxidative stress in atherosclerosis related diseases. Therefore, further prospective studies are needed to clarify whether FGF21 can be used as a prognostic biomarker to identify individuals at future risk of atherosclerosis in these atherosclerosis-associated diseases. In this review, we will discuss the possible mechanism by which FGF21 protects against atherosclerosis.

RAS/MAPK signaling functions in oxidative stress, DNA damage response and cancer progression.

J Cell Physiol 2019 Feb 27. Epub 2019 Feb 27.

Molecular Medicine Research Center, Tabriz University of Medical Sciences, Tabriz, Iran.

Mitogen-activated protein kinase (MAPK) signaling pathways organize a great constitution network that regulates several physiological processes, like cell growth, differentiation, and apoptotic cell death. Due to the crucial importance of this signaling pathway, dysregulation of the MAPK signaling cascades is involved in the pathogenesis of various human cancer types. Oxidative stress and DNA damage are two important factors which in common lead to carcinogenesis through dysregulation of this signaling pathway. Reactive oxygen species (ROS) are a common subproduct of oxidative energy metabolism and are considered to be a significant physiological modulator of several intracellular signaling pathways including the MAPK pathway. Studies demonstrated that the MAP kinases extracellular signal-regulated kinase (ERK) 1/2 and p38 were activated in response to oxidative stress. In addition, DNA damage is a partly common circumstance in cell life and may result in mutation, cancer, and even cell death. Recently, accumulating evidence illustrated that the MEK/ERK pathway is associated with the suitable performance of cellular DNA damage response (DDR), the main pathway of tumor suppression. During DDR, the MEK/ERK pathway is regularly activated, which contributes to the appropriate activation of DDR checkpoints to inhibit cell division. Therefore, the aim of this review is to comprehensively discuss the critical function of MAPK signaling in oxidative stress, DNA damage, and cancer progression.

CRISPR/Cas9 technology as a potent molecular tool for gene therapy.

J Cell Physiol 2019 08 30;234(8):12267-12277. Epub 2019 Jan 30.

Applied Biotechnology Research Center, Baqiyatallah University of Medical Sciences, Tehran, Iran.

Clustered regularly interspaced short palindromic repeats/CRISPR-associated nuclease 9 (CRISPR-Cas9) is an RNA-guided gene editing tool which offers several advantageous characteristics in comparison with the conventional methods (e.g., zinc finger nucleases and transcription activator-like effector nucleases) such as cost-effectiveness, flexibility, and being easy-to-use. Despite some limitations such as efficient delivery and safety, CRISPR-Cas9 is still the most convenient tool for gene editing purposes. Due to the potential capability of the CRISPR-Cas9 system in genome editing and correction of casual mutations, it can be considered as a possible therapeutic system in the treatment of disorders associated with the genome mutations and in particular cancer treatment. In this review, we will discuss CRISPR-Cas-based gene editing along with its classifications and mechanism of action. Furthermore, the therapeutic application of the CRISPR-Cas9 system in mutational disorders, delivery systems, as well as its advantages and limitations with a special emphasis on cancer treatment will be discussed.

Crosstalk between Phosphoinositide 3-kinase/Akt signaling pathway with DNA damage response and oxidative stress in cancer.

J Cell Biochem 2019 06 28;120(6):10248-10272. Epub 2018 Dec 28.

Solid Tumor Research Center, Urmia University of Medical Sciences, Urmia, Iran.

The phosphatidylinositol 3-kinases (PI3K)/Akt signaling pathway is one of the well-characterized and most important signaling pathways activated in response to DNA damage. This review discusses the most recent discoveries on the involvement of PI3K/Akt signaling pathway in cancer development, as well as stimulation of some important signaling networks involved in the maintenance of cellular homeostasis upon DNA damage, with an exploration of how PI3K/Akt signaling pathway contributes to the regulation of modulators and effectors underlying DNA damage response, the intricate, protein-based signal transduction network, which decides between cell cycle arrest, DNA repair, and apoptosis, the elimination of irreparably damaged cells to maintain homeostasis. The review continues by looking at the interplay between cell cycle checkpoints, checking the repair of damage inflicted to the DNA before entering DNA replication to facilitate DNA synthesis, and PI3K/Akt signaling pathway. We then investigate the challenges the cells overcome to ameliorate damages induced by oxidative activities, for example, the recruitment of many pathways and factors to maintain integrity and hemostasis. Finally, the review provides a discussion of how cells use the PI3K/Akt signaling pathway to regulate the balance between these networks.

Prevalence of osteoporosis with the World Health Organization diagnostic criteria in the Eastern Mediterranean Region: a systematic review and meta-analysis.

Arch Osteoporos 2018 11 17;13(1):129. Epub 2018 Nov 17.

Department of Orthopedics, Shahid Beheshti Hospital, Babol University of Medical Sciences, Babol, Iran.

A systematic review and meta-analysis was conducted on the prevalence of osteoporosis in the Eastern Mediterranean Region. The overall pooled prevalence of osteoporosis was 24.4%. The prevalence has increased significantly over the recent years. The highest pooled prevalence was in Saudi Arabia (32.7%), and the lowest was in Kuwait (15.1%).

Purpose: To conduct a systematic review and meta-analysis on the prevalence of osteoporosis in the Eastern Mediterranean Region (EMR), as defined by the World Health Organization.

Methods: We included all observational studies reporting the prevalence of osteoporosis among general population. We searched literatures from the databases of PubMed, Scopus, Web of Science, and Index Medicus for the EMR published between January 2000 and December 2017 with no restriction of language. Two reviewers independently contributed in study selection and data extraction. STATA software was used for analyzing the collected data.

Results: A total of 1692 citations were retrieved. After excluding the irrelevant articles, 36 eligible studies were included. The overall pooled prevalence rate of osteoporosis in the EMR on 31,593 participants was 24.4% (95% confidence interval [CI], 20.4-28.4). Based on femoral densitometry, the prevalence of osteoporosis was 16.8% (95% CI, 9.5-24.2), and based on spinal densitometry, it was 24.3% (95% CI, 19.4-29.2). The pooled prevalence in males was 20.5% (95% CI, 10.5-30.5), compared with 24.4% (95% CI, 20.2-28.6) in females. The prevalence rate was significantly higher in 2007-2015 (32.7%; 95% CI, 25.1-40.3) than in 2000-2006 (19.8%; 95% CI, 12.5-27).

Conclusions: Our findings indicate a considerable prevalence of osteoporosis among the people of the EMR. The prevalence has increased during recent years, showing that osteoporosis is becoming a critical health problem in this region. Prevention and control measures need to be implemented by health service authorities.

ALOX12 gene polymorphisms and serum selenium status in elderly osteoporotic patients.

Adv Clin Exp Med 2018 Dec;27(12):1717-1722

Department of Biochemistry, School of Medicine, Babol University of Medical Sciences, Iran.

Background: Osteoporosis is a systemic bone disease which leads to a reduction in bone mass. Many studies have shown that up to 80% of bone mineral density (BMD) variations are attributed to genetic factors. Arachidonate 12-lipoxygenase enzyme, encoded by the ALOX12 gene, produces lipid peroxides as reactive oxygen species (ROS), leading to oxidative stress and the development of osteoporosis. Selenium (Se) is incorporated into selenoproteins, which may reduce the risk of osteoporosis.

Objectives: We aimed to investigate the association of 2 ALOX12 single nucleotide polymorphisms (SNPs) and serum Se level with lumbar spine and femoral neck BMD among elderly individuals living in Amirkola, Iran.

Material And Methods: The study consisted of 180 individuals aged ≥60 years (90 healthy and 90 osteoporotic patients). We examined the effect of 2 ALOX12 SNPs (rs2292350 and rs9897850), using the polymerase chain reaction - restriction fragment length polymorphism (PCR-RFLP) on both BMD regions measured by dual energy X-ray absorptiometry (DXA). Serum Se level was measured using an atomic absorption spectrophotometer PGG990 AAS (PG Instruments Ltd., Luterworth, USA).

Results: The rs2292350 SNP showed a significant association with femoral neck BMD (p = 0.04). Moreover, in terms of serum Se level, a significant difference was found between the patient group (57.58 ±25.54 μg/L) and the control group (81.09 ±25.58 μg/L) (p < 0.001). In addition, individuals with higher serum Se levels also had higher BMD of the lumbar spine (r2 = 0.392; p < 0.001) and the femoral neck (r2 = 0.478; p < 0.001).

Conclusions: The results suggested that genetic variation in ALOX12 might influence BMD variations in our recruited participants. As for the patients with lower serum Se levels, it was observed that serum Se deficiency was accompanied by some ALOX12 variation, contributing to the development of osteoporosis.

An Apparent Correlation Between Central Nervous System and Kidney's Erythropoietin and TNF Alpha Expression at Peak Experimental Autoimmune Encephalomyelitis Disease.

J Mol Neurosci 2018 Jun 6;65(2):246-254. Epub 2018 Jun 6.

Cellular and Molecular Biology Research Center, Babol University of Medical Sciences, Babol, Iran.

Experimental autoimmune encephalomyelitis (EAE) is an inflammatory demyelination disease associated with inflammatory reactions and attenuation of antioxidant capacity. Several lines of evidence show that organs such as the liver and kidneys can share their antioxidant activity to protect the central nervous system (CNS) against neurodegenerative diseases. The aim of this study was to examine the possible interplay of the kidneys and CNS in pathogenesis of EAE. For this purpose, EAE model was induced in C57BL/6 mice, and expression of erythropoietin (EPO), TNF-α, and NFκB-1 was determined in the kidney and CNS at early and peak stages of the disease. Besides, changes in serum level of EPO and total antioxidant capacity (TAC) were measured by different clinical scores. Real-time PCR (qPCR) results showed a substantial increase in TNF-α and NFκB-1 expression in mice at EAE peak stage compared to sham (control). There was a positive correlation between kidney-EPO and CNS-inflammatory factor expression in EAE-induced mice. In general, EPO expression was relatively higher in the kidneys compared to CNS tissue in sham group. There was a significant upregulation in expression of EPO in the brain, spinal cord, and kidneys particularly at peak stage. Accordingly, changes in serum TAC were consistent with serum EPO concentration. This data may suggest that there is an EPO-mediated cross-talk between the kidney and CNS during EAE pathogenesis.

Aims: The purpose of the present study was to evaluate microRNA-140-3p expression level in breast cancer patients in comparison to healthy controls.

Patients & Methods: Serum microRNA-140-3p level was quantified by realtime quantitative reverse transcription PCR in 40 women with breast cancer and 40 healthy subjects.

Results: Serum microRNA-140-3p level in patients compared to healthy subjects was significantly up-regulated (P = 0.01). MicroRNA-140-3p had a good diagnostic accuracy for discrimination of the two groups (AUC = 0.667; sensitivity = 70%; specificity = 50%). Serum microRNA-140-3p level was overexpressed in premenopausal patients who were ≤48 years old. ROC curve showed a similar pattern again (AUC = 0.690; sensitivity = 73%; specificity = 50%).

Conclusions: microRNA-140-3p has the potential for detection of breast cancer, especially in premenopausal and in ≤48 years old women.

Background: Osteoporosis and osteopenia are common diseases in every population. Type 2 diabetes mellitus (T2DM) can lead to the development of various complications, such as bone disorders especially among elderly individuals. Studies suggested that ectonucleotide pyrophosphatase/phosphodiesterase1 (ENPP1) is contributed in insulin resistance and also the inhibition of bone mineralization. In this study, association of K121Q (rs1044498) polymorphism of the ENPP1 gene with T2DM and bone disorders is evaluated.

Methods: Four-hundred-and-ninety females who were classified based on bone mineral density (BMD) at lumbar spine and femur were included in this study. In addition, participants were classified according to their diabetes status. K121Q polymorphism was evaluated by the PCR-PFLF technique. One-way ANOVA was used for comparison of various analyzed factors in diseases subgroups and K121Q genotypes. Association of K121Q polymorphism with diabetes and bone disorders was evaluated by logistic regression.

Results: Significant association was observed between K121Q polymorphism with osteoporosis and osteopenia (p=0.041, p=0.029, respectively), but a similar pattern was not observed in T2DM status (p=0.723). Moreover, in diabetic patients, K121Q polymorphism showed a better prediction potential for the development of bone disorders in comparison to non-diabetic subjects (p=0.018; OR=4.63, p=0.540; OR=1.31). There were no significant differences between K121Q genotypes with FBS, Ca, P, vitamin D, PTH and BMD status.

Conclusions: The present study implies that K121Q polymorphism of ENPP1 gene is able to modulate the development of bone disorders in T2DM. Therefore in diabetic patients screening of this polymorphism is suggested for the monitoring of these persons.

Evaluation of scalp hair nickel and chromium level changes in patients with fixed orthodontic appliance: a one-year follow-up study.

Acta Odontol Scand 2018 Jan 9;76(1):1-5. Epub 2017 Sep 9.

d Social Determinant of Health Research Center, Health Research institute , Babol University of Medical Sciences , Babol , Iran.

Background And Objectives: The release of metal ions from orthodontic appliances is part of the dissolution and biomechanical processes of alloys. Nickel (Ni) and chromium (Cr) are the elements commonly used in the manufacture of various components of fixed orthodontic appliances, including bands, brackets and wires. This study was aimed to measure the Ni and Cr ions levels in the scalp hair of patients treated with fixed orthodontic appliances in comparison of the control group.

Materials And Methods: The patient group consisted of 24 patients treated with fixed orthodontic appliances for one year, while the control group included 28 healthy individuals without orthodontic appliances. Analysis of the Cr and Ni was performed using atomic absorption spectrophotometer by graphite furnace method. The data were analyzed via student and paired samples t-test and ANOVA repeated measurement test.

Results: After one year, the levels of Ni and Cr in two groups showed significant differences (0.086 ± 0.007 and 0.258 ± 0.009 µg/g for control group and 0.149 ± 0.010 and 0.339 ± 0.013 µg/g for patient group, respectively for Ni and Cr, p < .001). ANCOVA test by removing the effects of age, gender and the baseline levels of Ni and Cr showed that changes in these ions in the scalp hair of both groups after one year were statistically significant.

Conclusion: Due to the slightly elevated levels of Ni and Cr ions in the scalp hair of patients treated with fixed orthodontic appliances and considering the cytotoxic and allergic effects of these ions, changing the ingredients in fixed orthodontic appliances is suggested for the future.

Multiple Functions of Long Non-Coding RNAs in Oxidative Stress, DNA Damage Response and Cancer Progression.

J Cell Biochem 2018 01 17;119(1):223-236. Epub 2017 Aug 17.

Molecular Medicine Research Center, Tabriz University of Medical Sciences, Tabriz, Iran.

In addition to aberrant alternation of transcriptome, it is now suggested that dysregulation of the non-coding transcripts, particularly long non-coding RNAs (lncRNAs), which comprise the majority of the genome, is contributed to cancer initiation and progression. As the result of recent huge efforts, the possible roles of numerous lncRNAs in the human cancers were characterized, as well as various strategies with inhibitory effects to target these transcripts on the transformed cells. Moreover, DNA damage response (DDR) pathway is a complex regulatory network responsible for the identification of disruptions in DNA structure, integrity and stability- it is reported to be associated with the up-regulation and down-regulation of lncRNAs. This review explores the involvement of the various lncRNAs in different human cancers, afterwards discusses the association of the lncRNAs expression with the DDR and oxidative stress, which are implicated in a myriad pathophysiological and physiological intra- and extracellular damages.

Association of ATP-Binding Cassette Transporter A1 ()-565 C/T Gene Polymorphism with Hypoalphalipoproteinemia and Serum Lipids, IL-6 and CRP Levels.

Avicenna J Med Biotechnol 2017 Jan-Mar;9(1):38-43

Monoclonal Antibody Research Center, Avicenna Research Institute, ACECR, Tehran, Iran.

Background: ATP-binding cassette transporter A1 () is a membrane integral protein which plays a vital role in High Density Lipoprotein (HDL) metabolism and exerts a protective effect against Hypoalphalipoproteinemia (HA) by mediation of rate-limiting step in HDL biogenesis. In addition, this protein possesses anti-inflammatory effects by inhibiting the production of some inflammatory cytokines in macrophages. This study investigated the association of -565 C/T gene polymorphism with HA and serum lipids, IL-6 and CRP levels.

Methods: A population which consisted of 101 HA and 95 normal subjects were genotyped for -565C/T polymorphism by Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP). The serum concentrations of lipids, IL-6 and high sensitive-CRP (hs-CRP) were measured by the relevant methods.

Results: The frequency of T allele was significantly higher in the HA group than the controls (31.7 . 19.5%, p=0.002). Thus, carriers of the T allele (CT and TT genotypes) had a higher risk for HA (p=0.016, OR=2.04, 95% CI=1.14-3.63). T allele carriers demonstrated decreased HDL-C and increased triglyceride, IL-6 and CRP levels than those with the CC genotype.

Conclusion: This study suggests that the-565 C/T polymorphism of gene is associated with an increased risk of HA, decreased HDL-C and increased TG, IL-6 and CRP.

Osteoporosis is known as a degenerative disease of the skeletal system and its main complication is fracture, which influences quality of life in the elderly. There are 4 major blood groups in humans based on the presence of A and B antigens. According to the investigations, there are reported relations between blood types and some diseases. In this study, the association between the ABO blood group and the prevalence of osteoporosis and osteopenia in an elderly population was investigated. Medical records of 990 elderly people were investigated in a cross-sectional study and the association between their blood group and the incidence of osteoporosis and osteopenia was analyzed using SPSS version 17.0 (SPSS Inc., Chicago, IL, USA). The results showed that ABO blood groups had no association with the prevalence of osteoporosis in both elderly men and women. The association between age and osteoporosis was significant and the association between this disorder and gender was significant too. The results also indicate that there is no association between RH and RH blood types and osteoporosis and osteopenia in both men and women. Based on this finding, it would be reasonable to conduct extensive studies.

Human serum miR-34a as an indicator of exposure to ionizing radiation.

Radiat Environ Biophys 2016 11 25;55(4):423-429. Epub 2016 Aug 25.

Cellular and molecular biology research center, Health research institute, Babol University of Medical Sciences, Babol, Iran.

Radiation exposure in industrial accidents or nuclear device attacks is a major public health concern. There is an urgent need for markers that rapidly identify people exposed to ionizing radiation (IR). Finding a blood-based marker is advantageous because of the ease of sample collection. This study was designed to test the hypothesis that serum miR-34a could serve as an indicator of exposure to IR. Therefore, 44 women with breast cancer, where radiotherapy was part of their therapeutic protocol, were investigated in this study. After demonstrating the appropriateness of our microRNA (miRNA) extraction efficiency and miRNA assay in human serum, we analyzed the miR-34a level in paired serum samples before and after radiotherapy. Fifty Gy X-ray irradiation in daily dose fractions of 2 Gy, 5 days per week, was used in this study. We demonstrated that IR significantly increased serum level of miR-34a. By measuring miR-34a in serum, we could distinguish irradiated patients with sensitivity of 65 % and specificity of 75 %. According to this study, serum miR-34a has the potential to be used as an indicator of radiation exposure.

Pre and post radiotherapy serum oxidant/antioxidant status in breast cancer patients: Impact of age, BMI and clinical stage of the disease.

Rep Pract Oncol Radiother 2016 May-Jun;21(3):141-8. Epub 2016 Feb 10.

Cellular and Molecular Biology Research Center, Health Research Institute, Babol University of Medical Sciences, Babol, Iran.

Aim: In this study the effects of radiation therapy (RT) on serum oxidant/antioxidant status in breast cancer patients and the impact of age, BMI and clinical stage of the disease on the aforementioned variables were investigated.

Background: RT that is used for cancer treatment is dependent on the production of reactive oxygen species.

Materials And Methods: Eighty patients with breast cancer participated in this study and received RT at a dose of 50 Gy for 5 weeks. Blood samples were obtained in one day before and after the end of RT. Serum status of malondialdehyde (MDA), total antioxidant status (TAS), superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPx) were analyzed by spectrophotometry or ELISA and selenium (Se) level were analyzed by atomic absorption spectrometry. Paired t-test was used for comparing pre and post radiotherapy data.

Results: Before and after the radiotherapy, a significant increase in MDA level was observed, while a significant decrease in GPx activity, SOD, TAS and Se levels were found (p < 0.05). The level of the CAT enzyme had no significant changes (p = 0.568). The results showed some changes in the status of TAS, SOD and GPx which are associated with age, BMI and clinical stage of the disease.

Conclusion: It seems that RT would have the potential to cause variations in the status of antioxidant/oxidant system. Although, some changes in variables were observed by sub-classification of the age, BMI and the disease stage, but it seems that these changes are not necessarily dependent to them.

Hyaluronic acid algorithm-based models for assessment of liver fibrosis: translation from basic science to clinical application.

Hepatobiliary Pancreat Dis Int 2016 Apr;15(2):131-40

Student Research Committee & Department of Biochemistry and Biophysics, and Cellular and Molecular Biology Research Center, Health Research Institute, Babol University of Medical Sciences, Babol, Iran.

Background: The estimation of liver fibrosis is usually dependent on liver biopsy evaluation. Because of its disadvantages and side effects, researchers try to find non-invasive methods for the assessment of liver injuries. Hyaluronic acid has been proposed as an index for scoring the severity of fibrosis, alone or in algorithm models. The algorithm model in which hyaluronic acid was used as a major constituent was more reliable and accurate in diagnosis than hyaluronic acid alone. This review described various hyaluronic acid algorithm-based models for assessing liver fibrosis.

Data Source: A PubMed database search was performed to identify the articles relevant to hyaluronic acid algorithm-based models for estimating liver fibrosis.

Result: The use of hyaluronic acid in an algorithm model is an extra and valuable tool for assessing liver fibrosis.

Conclusions: Although hyaluronic acid algorithm-based models have good diagnostic power in liver fibrosis assessment, they cannot render the need for liver biopsy obsolete and it is better to use them in parallel with liver biopsy. They can be used when frequent liver biopsy is not possible in situations such as highlighting the efficacy of treatment protocol for liver fibrosis.

The status of antioxidants, malondialdehyde and some trace elements in serum of patients with breast cancer.

Caspian J Intern Med 2016 ;7(1):31-6

Babol University of Medical Sciences, Babol, Iran.

Background: There are studies that indicated dyshomeostasis of oxidant/antioxidant and trace elements in breast cancer patients, but the data regarding the status of these parameters in various stages of breast cancer are limited. The aim of this study was to highlight the status of these biochemical factors in various stages of breast cancer.

Methods: Fifty-eight breast cancers patients participated in this study and underwent staging work up for the assessment of disease stage. Serum total antioxidant capacity and lipid peroxidation were determined spectrophotometically. Glutathione peroxidase (GPX), catalase (CAT) and superoxide dismutase (SOD) levels were analyzed by ELISA method. The serum level of Cu, Mn and Zn was measured by atomic absorption spectrophotometer. Student t-test and one-way analysis of variance (ANOVA) were used to compare group means.

Results: All the patients included in the study classified as mild (stages I+II) and advanced stages (stages III+IV). Patients in advanced stage had lower serum antioxidant capacity and higher lipid peroxidation levels, but the differences were not statistically differet (P=0.690 and 0.666, respectively). Patients in advanced stage had higher, but not statistically different serum levels of CAT, GPX and SOD levels (p>0.05). Patients in both groups had to some extent similar serum Cu, Mn and Zn levels.

Conclusion: There was no evidence of remarkable discrepancy in the status of analyzed factors in various stages of breast cancer. It seems that the severity of oxidative stress in different stages of breast cancer is similar to some extent.
