A dietary pattern rich in fruits and dairy products is inversely associated to gestational diabetes: a case-control study in Iran.

BMC Endocr Disord 2021 Mar 4;21(1):41. Epub 2021 Mar 4.

Department of Advanced Medical Sciences and Technologies, School of Medicine, Jahrom University of Medical Sciences, Jahrom, Iran.

Background: Gestational diabetes mellitus (GDM) causes many problems for mother and her neonate. A healthy diet plays an important role in preventing GDM. This study aimed to investigate the relationship between major dietary patterns and the GDM.

Methods: 386 healthy and 306 GDM pregnant women (total 693) completed this case-control study. Basic information and anthropometric indices were recorded, and a food frequency questionnaire was completed. For extracting major dietary patterns, the principal component analysis was performed. Multivariable logistic regression models were used to examine whether specific dietary patterns are associated to the GDM.

Results: Four dietary patterns were identified: "fruits and dairy products", "red meat and plant-based foods", "snacks and high-fat foods" and "carbohydrate-rich foods". Among these major extracted dietary patterns, "fruits and dairy products" showed an inverse association to the GDM (odds ratio adjusted for confounders: 0.50, confidence interval: 0.284-0.882, p-trend = 0.019, for highest vs. lowest quartile).

Conclusions: It seems using a healthy dietary pattern such as "fruits and dairy products" may decrease GDM risk.

Association of arginine vasopressin (AVP) promoter polymorphisms with preeclampsia.

Pregnancy Hypertens 2019 Oct 5;18:122-125. Epub 2019 Oct 5.

Department of Biochemistry, Department of Advanced Medical Sciences and Technologies, Research Center for Non-Communicable Diseases, Jahrom University of Medical Sciences, Jahrom, Iran. Electronic address:

Objectives: Preeclampsia (PE) is a disease of pregnancy characterized by early onset of maternal hypertension and proteinuria. New findings indicate that arginine vasopressin (AVP) may be a contributing factor to ignite PE. The aim of this study was to identify if there is any correlation between arginine vasopressin promoter polymorphisms and PE.

Study Design: Venous blood samples of 100 PE and 100 normal pregnant women were obtained for DNA extraction to identify the polymorphisms of AVP promoter by RFLP and nested-PCR techniques.

Main Outcome: rs3729965 polymorphism of PE women was detected to have significant correlation with body mass index (BMI) (P = 0.028).

Results: Statistical analysis of three polymorphisms namely rs3729965, rs61138008 and rs3761249 of preeclamptic women (PEW) and none preeclamptic pregnant women (NPEW) revealed that rs3729965 genotypic distribution was significantly different between both groups (P = 0.04). Further analysis revealed that rs3729965 CT genotype of PEW had significant correlation to their BMI (P = 0.028).

Conclusion: Polymorphic variants located on the promoter region of AVP are associated with PE. Thus we hypothesize that allelic variation may have a role in increasing the risk of developing PE.

Case-control study on the association between the GATA2 gene and premature myocardial infarction in the Iranian population.

Herz 2021 Feb 29;46(1):71-75. Epub 2019 Aug 29.

Research Center for Non-Communicable Diseases, Jahrom University of Medical Sciences, Jahrom, Iran.

In recent decades, due to the high prevalence of coronary artery disease (CAD) and myocardial infarction (MI), numerous studies have attempted to elucidate genetic contributing factors in these complex disorders. A very interesting gene in this regard is GATA-binding protein 2 (GATA2), an important regulator of various gene expressions in vascular endothelial cells. Accordingly, the association of different GATA2 polymorphisms with CAD and MI has already been evaluated. Rs2713604 is a genetic marker whose association with CAD has not been reproduced in previous studies. Considering the importance of replicating the initial association, the present case-control study aimed to examine the association of this intronic variant with premature MI in a sample of the Iranian population. In this study, 193 participants from Jahrom Hospital (Jahrom, Iran) were consecutively recruited during a 1.5-year period, and, following blood sampling, genomic DNA was extracted. We then proceeded to genotype rs2713604 using the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method and statistically analyzed the data. After adjustment for hyperlipidemia, hypertension, and type 2 diabetes mellitus, the results of the multivariate regression analysis showed no significant association between rs2713604 and premature MI. Interestingly, the risk allele (A-allele) of rs2713604 displayed a slightly higher frequency among controls compared to cases.

Immunomodulatory Effects of Human Adipose Tissue-derived Mesenchymal Stem Cells on T Cell Subsets in Patients with Rheumatoid Arthritis.

Iran J Allergy Asthma Immunol 2019 Feb;18(1):114-119

Research Center for Non-Communicable Diseases, School of Medicine, Jahrom University of Medical Sciences, Jahrom, Iran.

Adipose-derived mesenchymal stem cells (Ad-MSCs) have been reported to suppress the effector T cell responses and have beneficial effects on various immune disorders, like rheumatoid arthritis (RA). This study was designed to investigate the effects of co-cultured Ad-MSCs on peripheral blood mononuclear cells (PBMCs) of RA patients and healthy individuals, through assessing transcription factors of T cell subsets. PBMCs from RA patients and healthy donors were co-cultured with Ad-MSCs with or without Phytohaemagglutinin (PHA). The quantitative real-time polymerase chain reaction (qRT-PCR) was used to measure the expression of T-box 21 (T-bet), GATA-binding protein-3 (GATA3), retinoid-related orphan receptor γt (ROR-γt) and forkhead box P3 (Foxp3). Based on the results, Ad-MSCs greatly upregulated Th2 and Treg cell transcription factors, i.e., GATA3 and Foxp3 (p<0.05), and downregulated Th1 and Th17 transcription factors, i.e., T-bet and RORγt (p<0.05). These results demonstrate that Ad-MSCs can result in an immunosuppressive environment through inhibition of pro-inflammatory T cells and induction of T cells with a regulatory phenotype. Therefore, they might have important clinical implications for inflammatory and autoimmune diseases such as RA.

Study of the mechanisms of crocetin-induced differentiation and apoptosis in human acute promyelocytic leukemia cells.

J Cell Biochem 2018 Sep 11. Epub 2018 Sep 11.

Department of New Sciences and Technology, Faculty of Medicine, Mashhad University of Medical Sciences, Mashhad, Iran.

Crocetin, the major carotenoid in saffron, exhibits potent anticancer effects. However, the antileukemic effects of crocetin are still unclear, especially in primary acute promyelocytic leukemia (APL) cells. In the current study, the potential antipromyelocytic leukemia activity of crocetin and the underlying molecular mechanisms were investigated. Crocetin (100 µM), like standard anti-APL drugs, all-trans retinoic acid (ATRA, 10 µM) and As O (arsenic trioxide, 50 µM), significantly inhibited proliferation and induced apoptosis in primary APL cells, as well as NB4 and HL60 cells. The effect was associated with the decreased expressions of prosurvival genes Akt and BCL2, the multidrug resistance (MDR) proteins, ABCB1 and ABCC1 and the inhibition of tyrosyl-DNA phosphodiesterase 1 (TDP1), while the expressions of proapoptotic genes CASP3, CASP9, and BAX/BCL2 ratio were significantly increased. In contrast, crocetin at relatively low concentration (10 µM), like ATRA (1 µM) and As O (0.5 µM), induced differentiation of leukemic cells toward granulocytic pattern, and increased the number of differentiated cells expressing CD11b and CD14, while the number of the immature cells expressing CD34 or CD33 was decreased. Furthermore, crocetin suppressed the expression of clinical marker promyelocytic leukemia/retinoic acid receptor-α ( PML/RARα) in NB4 and primary APL cells, and reduced the expression of histone deacetylase 1 ( HDAC1) in all leukemic cells. The results suggested that crocetin can be considered as a candidate for future preclinical and clinical trials of complementary APL treatment.

Epigallocatechin-3-gallate enhances differentiation of acute promyelocytic leukemia cells via inhibition of PML-RARα and HDAC1.

Phytother Res 2018 Mar 29;32(3):471-479. Epub 2017 Nov 29.

Biotechnology Research Center, Pharmaceutical Technology Institute, Mashhad University of Medical Sciences, Mashhad, Iran.

The use of all-trans retinoic acid (ATRA) has dramatically improved the treatment and survival rate of patients with acute promyelocytic leukemia (APL). However, toxicity and resistance to this drug are major problems in the treatment of APL with ATRA. Earlier studies have suggested that the green tea polyphenol epigallocatechin gallate (EGCG) induces cell death in hematopoietic neoplasms without adversely affecting normal cells. In the present study, the potential therapeutic effect of EGCG in APL and the underlying molecular mechanisms were investigated. EGCG (100 μM) significantly inhibited proliferation and induced apoptosis in HL-60 and NB4 cells. This effect was associated with decreased expressions of multidrug resistance proteins ABCB1, and ABCC1, whereas the expressions of pro-apoptotic genes CASP3, CASP8, p21, and Bax/Bcl-2 ratio were significantly increased. EGCG, at 25 μM concentration, induced differentiation of leukemic cells towards granulocytic pattern in a similar manner to that observed for ATRA (1 μM). Furthermore, EGCG suppressed the expression of clinical marker PML/RARα in NB4 cells and reduced the expression of HDAC1 in leukemic cells. In conclusion, the results suggested that EGCG can be considered as a potential treatment for APL.

Kaempferol increases apoptosis in human acute promyelocytic leukemia cells and inhibits multidrug resistance genes.

J Cell Biochem 2018 02 20;119(2):2288-2297. Epub 2017 Oct 20.

Biotechnology Research Center, Mashhad University of Medical Sciences, Mashhad, Iran.

Acute promyelocytic leukemia (APL) is one of the most life-threatening hematological malignancies. Defects in the cell growth and apoptotic pathways are responsible for both disease pathogenesis and treatment resistance. Therefore, pro-apoptotic agents are potential candidates for APL treatment. Kaempferol is a flavonoid with antioxidant and anti-tumor properties. This study was designed to investigate the cytotoxic, pro-apoptotic, and differentiation-inducing effects of kaempferol on HL-60 and NB4 leukemia cells. Resazurin assay was used to determine cell viability following treatment with kaempferol (12.5-100 μM) and all-trans retinoic acid (ATRA; 10 μM; used as a positive control). Apoptosis and differentiation were also detected using propidium iodide and NBT staining techniques, respectively. Furthermore, the expression levels of genes involved in apoptosis (PI3 K, AKT, BCL2, BAX, p53, p21, PTEN, CASP3, CASP8, and CASP9), differentiation (PML-RAR and HDAC1), and multi-drug resistance (ABCB1 and ABCC1) were determined using quantitative real-time PCR. The protein expressions of Bax/Bcl2 and casp3 were confirmed using Western blot. The results showed that kaempferol decreased cell viability and increased subG1 population in the tested leukemic cells. This effect was associated with decreased expression of Akt, BCL2, ABCB1, and ABCC1 genes, while the expression of CASP3 and BAX/BCL-2 ratio were significantly increased at both gene and protein levels. Kaempferol promoted apoptosis and inhibited multidrug resistance in a concentration-dependent manner, without any differential effect on leukemic cells. In conclusion, this study suggested that kaempferol may be utilized as an appropriate alternative for ATRA in APL patients.

Epigallocatechin-3-gallate promotes apoptosis in human breast cancer T47D cells through down-regulation of PI3K/AKT and Telomerase.

Pharmacol Rep 2017 Oct 13;69(5):924-928. Epub 2017 Apr 13.

Department of Microbiology, Jahrom University of Medical Sciences, Jahrom, Iran.

Background: Green tea has antioxidant, anti-tumor and anti-bacterial properties. Epigallocatechin-3-gallate (EGCG) in green tea is highly active as a cancer chemopreventive agent. In this study, we designed a series of experiments to examine the effects of EGCG on proliferation and apoptosis of estrogen receptor α-positive breast cancer (T47D) cells.

Methods: Cells were treated with EGCG (0-80μM) and tamoxifen (0-20μM), as the positive control, up to 72h. Cell viability was determined by MTT assay. Apoptosis investigated by real time PCR of apoptosis and survival (Bax, Bcl-2, p21, p53, PTEN, PI3K, AKT, caspase3 and caspase9 and hTERT) genes and by western blot of Bax/Bcl-2 proteins expressions.

Results: The results showed that EGCG decreased cell viability as concentration- and time-dependently. IC values were 14.17μM for T47D and 193.10μM for HFF cells, as compared with 3.39μM and 32.75μM for tamoxifen after 72h treatment, respectively. Also, EGCG (80μM) significantly increased the genes of PTEN, CASP3, CASP9 and decreased AKT approximately equal to tamoxifen. In gene expression, EGCG (80μM) significantly increased Bax/Bcl-2 ratio to 8-fold vise 15-fold in tamoxifen (20μM)-treated T47D cells during 72h. In protein expression of Bax/Bcl-2, EGCG significantly increased 6-fold while this ratio augmented 10-fold in tamoxifen group. EGCG significantly decreased 0.8, 0.4 and 0.3 gene expression of hTERT in 24, 48 and 72h, respectively.

Conclusions: This study suggests that EGCG may be a useful adjuvant therapeutic agent for the treatment of breast cancer.

Human adipose tissue-derived mesenchymal stem cells in rheumatoid arthritis: Regulatory effects on peripheral blood mononuclear cells activation.

Int Immunopharmacol 2017 Jun 30;47:59-69. Epub 2017 Mar 30.

Department of Immunology and Microbiology, School of Medicine, Jahrom University of Medical Sciences, Jahrom, Iran.

Background And Objectives: Mesenchymal stem cells (MSCs) are multipotent adult stem cells with immunomodulatory properties. The mechanisms by which MSCs inhibit the proliferation of pro-inflammatory T cells have not been fully elucidated yet. It is assumed that pro-inflammatory T-cells play an important role in the development of autoimmune diseases. We investigated the potential therapeutic effects of human adipose tissue derived (Ad)-MSCs on the peripheral blood mononuclear cells (PBMCs) of rheumatoid arthritis (RA) patients and healthy individuals, with a particular focus on Th17-associated cytokines.

Materials And Methods: PBMCs from RA patients and healthy donors were co-cultured with Ad-MSCs and HeLa with or without Phytohemagglutinin (PHA). Finally, IL-6, IL-17, IL-21, IL-23 and TGF-β levels were determined by ELISA and quantitative real-time RT-PCR on co-culture supernatants and PBMCs, respectively.

Results: In co-culture interaction, Ad-MSCs inhibited IL-17 secretion by PBMCs compared to unstimulated PBMCs cultured alone. In addition, IL-21 expressions in PBMCs of the patient group, and IL-17 and IL-21 in healthy group were inhibited by Ad-MSCs compared to PBMCs cultured alone. TGF-β expression in healthy individuals remarkably increased in both MSC-treated groups with and without PHA in comparison to PHA-stimulated and -unstimulated PBMCs.

Conclusions: This study demonstrates that human Ad-MSCs act as key regulators of immune tolerance by inhibiting the inflammation. Therefore, they can be attractive candidates for immunomodulatory cell-based therapy in RA.

Kaempferol increases apoptosis in human cervical cancer HeLa cells via PI3K/AKT and telomerase pathways.

Biomed Pharmacother 2017 May 1;89:573-577. Epub 2017 Mar 1.

Research Center for Non Communicable Diseases, Jahrom University of Medical Sciences, Motahari Avenue, Jahrom, Iran. Electronic address:

Cervical cancer is one of the most frequent cancers in women worldwide. Defects in the apoptotic pathways are responsible for both the disease pathogenesis and its therapy resistance. It is thus a good candidate for treatment by pro-apoptotic agents. Kaempferol as a flavonoid has antioxidant and anti-tumor properties. Kaempferol has been shown to induce apoptosis and cell death in cancer cells. However, due to the problems in the treatment of cervical cancer, this study is designed to investigate the molecular mechanism by which kaempferol suppresses the growth of cervical cancer HeLa cell as compared with HFF cells (normal cells). Cells treated with kaempferol (12-100μM) and 5-FU (1-10μM), as the positive control, up to 72h. Cell viability was determined by MTT assay and real time PCR was used to investigate apoptosis and telomerase genes expression. The results showed that kaempferol decreased cell viability as concentration- and time-dependently. IC values were 10.48μM for HeLa and 707.00μM for HFF cells, as compared with 1.40μM and 16.38μM for 5-FU after 72h treatment, respectively. Also, kaempferol induced cellular apoptosis and aging through down-regulating the PI3K/AKT and hTERT pathways. This study suggests that kaempferol may be a useful adjuvant therapeutic agent in the treatment of cervical cancer.

Sero-Epidemiological Study of Hepatitis E Virus among Thalassemia as High Risk Patients: A Cross-Sectional Survey in Jahrom, Southern, Iran.

Glob J Health Sci 2016 9 1;8(9):53885. Epub 2016 Sep 1.

Zonoses Research Center, Jahrom University of Medical Sciences, Jahrom,.

Hepatitis E virus (HEV) could be cause of viral hepatitis in the developing countries and cause severe epidemics. According to other studies, blood transfusion as a probable route of HEV infection has been suggested. An infection with hepatitis agents such as HEV causes active liver failure in multi-transfusion patients in particular thalassemia. The purpose of this study determines the seropositivity of anti-HEV antibodies in thalassemia individuals in Jahrom. In a cross-sectional study, sera from 110 thalassemia were collected between 2013 and 2014. Enzyme-linked immunosorbent assay (ELISA) method was performed to detection of anti-HEV antibodies. Individuals' data were collected such as, demographic and clinical, for statistical analysis. Our results show that 10% and 1.8% of the enrolled patients were HEV Ig-G and Ig-M positive antibodies respectively. In addition, there was statiscally significant difference in age groups for prevalence of anti-HEV Ig-G (P = 0.01). Also the serum levels of liver enzymes such as ALT and AST in the HEV Ig-G and Ig-M positive samples were significantly higher than anti-HEV negative samples. But there were no significant difference between sex and splenectomy with anti-HEV positive samples. The results indicate more study are needed to assess HEV screening of blood products to these patients that those have a probably risk of exposure to HEV especially in higher years old.

Non-Association between rs7903146 and rs12255372 Polymorphisms in Transcription Factor 7-Like 2 Gene and Type 2 Diabetes Mellitus in Jahrom City, Iran.

Diabetes Metab J 2015 Dec 13;39(6):512-7. Epub 2015 Nov 13.

Research Center for Non-Communicable Diseases, Jahrom University of Medical Sciences, Jahrom, Iran.

Background: Transcription factor 7-like 2 (TCF7L2) is a transcription factor in the Wnt signaling pathway. High levels of TCF7L2 have been reported in most human tissues, including the heart, lung, brain, liver, kidney, placenta, adipose tissues, and pancreatic β-cells. The purpose of this study was to assess the association between TCF7L2 polymorphisms (rs12255372 and rs7903146) and type 2 diabetes mellitus in the city of Jahrom, Iran.

Methods: This case-control study was conducted with 200 patients referred to Diabetes Clinics and 200 healthy subjects in Jahrom City. Biochemical characteristics were first determined. TCF7L2 rs1255372 and rs7903146 polymorphisms were then genotyped using the polymerase chain reaction-restriction fragment length polymorphism method.

Results: T-allele frequencies of both single nucleotide polymorphisms (SNPs) were significantly higher in diabetic patients than in normal glucose-tolerant subjects (rs12255372: 20.3% vs. 14.5%; rs7903146: 28.5% vs. 22.25%). The rs12255372 (G/T) polymorphism analysis showed an odds ratio of 0.473 (95% confidence interval [CI], 0.170 to 1.314; P=0.151) for the TT genotype and 0.646 (95% CI, 0.410 to 1.019; P=0.060) for the TG genotype, compared with the GG genotype. The rs7903146 (C/T) polymorphism odds ratios for TT and TC genotypes were 0.564 (95% CI, 0.280 to 1.135; P=0.109) and 0.751 (95% CI, 0.487 to 1.157; P=0.194) compared with the CC genotype, respectively.

Conclusion: The rs12255372 and rs7903146 SNPs of the TCF7L2 gene were not associated with insulin resistance in the evaluated population.
