Background DNA methyltransferases (DNMTs) are epigenetic enzymes involved in embryonic development, cell differentiation, epithelial to mesenchymal transition, and control of gene expression, whose overexpression or enhanced catalytic activity has been widely reported in cancer initiation and progression. To date, two DNMT inhibitors (DNMTi), 5-azacytidine (5-AZA) and 5-aza-2′-deoxycytidine (DAC),...
Background Efficient treatments against metastatic melanoma dissemination are still lacking. Here, we report that low-cytotoxic concentrations of 5-aza-2′-deoxycytidine, a DNA demethylating agent, prevent in vitro 3D invasiveness of metastatic melanoma cells and reduce lung metastasis formation in vivo. Results We unravelled that this beneficial effect is in part due to MIR-199A2 re-expression by...
This review presents the different human DNA methyltransferases (DNMTs), their biological roles, their mechanisms of action and their role in cancer. The description of assays for detecting DNMT inhibitors (DNMTi) follows. The different known DNMTi are reported along with their advantages, drawbacks and clinical trials. A discussion on the features of the future DNMT inhibitors will conclude this...
