Biobank Education for Future Physicians: Training Medical Students Through Student Research Association Networks.

Research biobanks have become crucial collaborators in a variety of basic and clinical research projects with comprehensive biological sample collection and associated data storage. Medical students, who are the most important stakeholders of biobanks as future physicians, need to be trained in biobanking; however, there is no consensus on how to include it in formal education. This study aimed to determine and increase awareness among medical students regarding biobanks through peer training organized online by medical student research association networks.

Role of Biobanks for Cancer Research and Precision Medicine in Hepatocellular Carcinoma.

Introduction: Hepatocellular carcinoma (HCC) is a highly complex and deadly cancer. There is an urgent need for new and effective treatment modalities. Since the primary goal in the management of cancer is to cure and improve survival, personalized therapy can increase survival, reduce mortality rates, and improve quality of life.

A Novel Function for KLF4 in Modulating the De-differentiation of EpCAM/CD133 nonStem Cells into EpCAM/CD133 Liver Cancer Stem Cells in HCC Cell Line HuH7.

The complex and heterogeneous nature of hepatocellular carcinoma (HCC) hampers the identification of effective therapeutic strategies. Cancer stem cells (CSCs) represent a fraction of cells within tumors with the ability to self-renew and differentiate, and thus significantly contribute to the formation and maintenance of heterogeneous tumor mass. Increasing evidence indicates high plasticity in tumor cells, suggesting that non-CSCs could acquire stem cell properties through de-differentiation or reprogramming processes.

The Transcription Factor Is Essential for a Successful Mesenchymal to Epithelial Transition.

The epithelial to mesenchymal transition (EMT) and the mesenchymal to epithelial transition (MET) are two critical biological processes that are involved in both physiological events such as embryogenesis and development and also pathological events such as tumorigenesis. They present with dramatic changes in cellular morphology and gene expression exhibiting acute changes in E-cadherin expression. Despite the comprehensive understanding of EMT, the regulation of MET is far from being understood.

Antiproliferative activity of (R)-4'-methylklavuzon on hepatocellular carcinoma cells and EpCAM/CD133 cancer stem cells via SIRT1 and Exportin-1 (CRM1) inhibition.

Cytotoxic effects of (R)-4'-methylklavuzon were investigated on hepatocellular carcinoma cells (HuH-7 and HepG2) and HuH-7 EpCAM/CD133 cancer stem cells. IC of (R)-4'-methylklavuzon was found as 1.25 μM for HuH-7 parental cells while it was found as 2.

Effect of adipocyte-secreted factors on EpCAM+/CD133+ hepatic stem cell population.

Recent epidemiological studies have associated obesity with a variety of cancer types including HCC. However, the tumor initiating role of obesity in hepatocarcinogenesis is still unknown. The objective of this paper is to investigate the effect of adipocyte-secreted factors on EpCAM+/CD133+ cancer stem cells and to identify which factors play a role in modulating hepatic cancer stem cell behavior.

Heparin treatment increases thioredoxin interacting protein expression in hepatocellular carcinoma cells.

Heparins play an important role in cell growth, differentiation, migration and invasion. However, the molecular mechanisms of heparin mediated cellular behaviors are not well defined. To determine the effect of heparin on gene expression, we performed a cDNA microarray in a hepatocellular carcinoma cell line and found that heparin regulates transcription of genes involved in glucose metabolism.
