Pathology and Tumor Biology, Graduate School of Medicine, Kyoto University.

Recent advances in sequencing technologies have increased the detection rate for identifying germline mutations that predispose an individual to various myeloid neoplasms and somatic mutations acquired during progression from myelodysplastic syndromes (MDS) to acute myeloid leukemia (AML). In addition to pediatric subjects, adult patients were analyzed in order to obtain a complete spectrum of driver mutations in germline cells and/or somatic tumor samples. As shown in several recent studies, such driver mutations are acquired in a gene-specific fashion. Read More

Exploring the Modulatory Effects of Gut Microbiota in Anti-Cancer Therapy.

Front Oncol 2021 13;11:644454. Epub 2021 Apr 13.

Department of Gastrointestinal Surgery, The Second Affiliated Hospital of Nanchang University, Nanchang, China.

In the recent decade, gut microbiota has received growing interest due to its role in human health and disease. On the one hand, by utilizing the signaling pathways of the host and interacting with the immune system, the gut microbiota is able to maintain the homeostasis in human body. This important role is mainly modulated by the composition of microbiota, as a normal microbiota composition is responsible for maintaining the homeostasis of human body, while an altered microbiota profile could contribute to several pathogenic conditions and may further lead to oncogenesis and tumor progression.

Immunomodulatory Effect of Microglia-Released Cytokines in Gliomas.

Brain Sci 2021 Apr 7;11(4). Epub 2021 Apr 7.

Department of Chemical, Biological, Pharmaceutical and Environmental Sciences, University of Messina, Viale Ferdinando Stagno D'Alcontres, 98166 Messina, Italy.

Microglia, a type of differentiated tissue macrophage, are considered to be the most plastic cell population of the central nervous system (CNS). Microglia substantially contribute to the growth and invasion of tumor mass in brain tumors including glioblastoma (GB). In response to pathological conditions, resting microglia undergo a stereotypic activation process and become capable of phagocytosis, antigen presentation, and lymphocyte activation. Read More

Serum midkine is a more sensitive predictor for hepatocellular carcinoma than Dickkopf-1 and alpha-L-fucosidase in cirrhotic HCV patients.

Medicine (Baltimore) 2021 Apr;100(17):e25112

Hepatology, Gastroentrology and Infectious Diseases Department, Faculty of Medicine, Kafrelsheikh University, Kafrelsheikh, Egypt.

Abstract: Alpha fetoprotein (AFP) level is the gold standard diagnostic tool for detection and monitoring hepatocellular carcinoma (HCC) but with low sensitivity. Thus, the identification of alternative or combined serum markers of HCC is highly needed. Therefore, the aim of this work was to verify the value of serum midkine (MDK), Dickkopf-related protein 1 (DKK1), and alpha-L-fucosidase (AFU) in detection of HCC. Read More

Specific Protein 1 and p53 Interplay Modulates the Expression of the KCTD-Containing Cullin3 Adaptor Suppressor of Hedgehog 2.

Front Cell Dev Biol 2021 8;9:638508. Epub 2021 Apr 8.

Department of Experimental Medicine, Sapienza University, Rome, Italy.

The Hedgehog (Hh) signaling pathway plays a crucial role in normal embryonic development and adult tissue homeostasis. On the other end, dysregulated Hh signaling triggers a prolonged mitogenic response that may prompt abnormal cell proliferation, favoring tumorigenesis. Indeed, about 30% of medulloblastomas (MBs), the most common malignant childhood cerebellar tumors, exhibit improper activation of the Hh signaling. Read More

A Patient with an Ileocecal MiNEN and a Synchronous Squamous Non-Small-Cell Lung Cancer: Case Report and Review of the Literature.

Case Rep Oncol Med 2021 31;2021:8896254. Epub 2021 Mar 31.

Medical Oncology Department, Hospital Universitario 12 de Octubre, Madrid, Spain.

Mixed neuroendocrine non-neuroendocrine neoplasms (MiNENs) are rare tumors composed of two different histological components, one of which is of a neuroendocrine origin. Given its suggested underdiagnosis and consequent low prevalence, no clear diagnostic and treatment guidelines are available, and treatment usually follows regimens similar to that of the most aggressive component. On the other hand, multiple primary tumors (MPTs) are also rare neoplastic entities that usually confer a challenge regarding treatment options, for a regimen that comprises both the primary and the synchronous/metachronous malignancy should be used.

Tianjin Key Laboratory of Acute Abdomen Disease Associated Organ Injury and ITCWM Repair, Tianjin Nankai Hospital, Tianjin 300100, China. Corresponding author: Wang Ximo, Email:

Neutrophils are the most abundant circulating leukocyte type in humans and comprise the host's first line of cellular defense against foreign pathogens invasion. On the other hand, neutrophils are the main mediators of tissue damage induced by acute and chronic inflammation. They were once considered to be short-lived, low transcriptional activity, and terminally differentiated homogeneous leucocytes that failed to return to circulation from tissue. Read More

Int J Mol Sci 2021 Mar 5;22(5). Epub 2021 Mar 5.

Department of Biochemistry, McGill University, Montréal, QC H3G 1Y6, Canada.

Oncogenic kinases contribute to immunosuppression and modulate the tumor microenvironment in solid tumors. Increasing evidence supports the fundamental role of oncogenic kinase signaling networks in coordinating immunosuppressive tumor microenvironments. This has led to numerous studies examining the efficacy of kinase inhibitors in inducing anti-tumor immune responses by increasing tumor immunogenicity. Read More

Modulation by Ozone Therapy of Oxidative Stress in Chemotherapy-Induced Peripheral Neuropathy: The Background for a Randomized Clinical Trial.

Int J Mol Sci 2021 Mar 10;22(6). Epub 2021 Mar 10.

Institute for Applied Microelectronics (IUMA), University of Las Palmas de Gran Canaria (ULPGC), 35017 Las Palmas de Gran Canaria, Spain.

(1) Background: Chemotherapy-induced peripheral neuropathy (CIPN) decreases the quality of life of patients and can lead to a dose reduction and/or the interruption of chemotherapy treatment, limiting its effectiveness. Potential pathophysiological mechanisms involved in the pathogenesis of CIPN include chronic oxidative stress and subsequent increase in free radicals and proinflammatory cytokines. Approaches for the treatment of CIPN are highly limited in their number and efficacy, although several antioxidant-based therapies have been tried. Read More

EGCG Inhibits Adipose-Derived Mesenchymal Stem Cells Differentiation into Adipocytes and Prevents a STAT3-Mediated Paracrine Oncogenic Control of Triple-Negative Breast Cancer Cell Invasive Phenotype.

Molecules 2021 Mar 10;26(6). Epub 2021 Mar 10.

Laboratoire d'Oncologie Moléculaire, Département de Chimie, Centre de Recherche CERMO-FC, Université du Québec à Montréal, Montréal, QC H3C 3P8, Canada.

Obese subjects have an increased risk of developing triple-negative breast cancer (TNBC), in part associated with the chronic low-grade inflammation state. On the other hand, epidemiological data indicates that increased consumption of polyphenol-rich fruits and vegetables plays a key role in reducing incidence of some cancer types. Here, we tested whether green tea-derived epigallocatechin-3-gallate (EGCG) could alter adipose-derived mesenchymal stem cell differentiation into adipocytes, and how this impacts the secretome profile and paracrine regulation of the TNBC invasive phenotype.
