Role of cell adhesion signal molecules in hepatocellular carcinoma cell apoptosis

Characterization of hepatocellular carcinoma cell lines based on cell adhesion molecules.

Many studies which focus on the molecules and mechanisms related to the characteristics of the cancer have been performed. In particular, cell adhesion molecules (CAMs) are known to play a central role in the adhesion of cancer cells to vascular endothelial cells. In this study, the expression of CAMs in hepatocellular carcinoma (HCC) cell lines w...

Signal transduction and signal modulation by cell adhesion receptors: the role of integrins, cadherins, immunoglobulin-cell adhesion molecules, and selectins.

Effects of 5-aza-2ˈ-deoxycytidine and Valproic Acid on Epigenetic-modifying DNMT1 Gene Expression, Apoptosis Induction and Cell Viability in Hepatocellular Carcinoma WCH-17 cell line

Background: DNA molecule of the eukaryotic cells is found in the form of a nucleoprotein complex named chromatin. Two epigenetic modifications are critical for transcriptional control of genes, including acetylation and DNA methylation. Hypermethylation of tumor suppressor genes is catalyzed by various DNA methyltransferase enzymes (DNMTs), including DNMT1, DNMT2, and DNMT3. The most well chara...

The role of junctional adhesion molecules in cell-cell interactions.

Cell-cell-interactions are important for the regulation of tissue integrity, the generation of barriers between different tissues and body compartments thereby providing an effective defence against toxic or pathogenic agents, as well as for the regulation of inflammatory cell recruitment. Intercellular interactions are regulated by adhesion receptors on adjacent cells which upon extracellular ...

Role of Brg1 in progression of esophageal squamous cell carcinoma

Objective(s): Epigenetic regulation of gene expression can be carried out through chromatin remodeling enzymes such as SWI/SNF. Brg1 also known as SMARCA4 is a catalytic subunit of SWI/SNF, which is necessary for MMPs expression. Matrix metalloproteinases (MMPs) are known as important player enzymes during tumor progression and metastasis. Aberrant epigenetic modification of chromatin should be...
