A leading therapeutic strategy in treating solid tumors stems from the use of demethylating agents to suppress DNA methylation in cancerous growths. Azacitidine and decitabine are both frequently used demethylating agents while decitabine is significantly more potent in its demethylating abilities. See more Demethylating agents are chemical substances that can inhibit methylation, resulting in the expression of the previously hypermethylated silenced genes (see Methylation#Cancer for more detail). Cytidine analogs … See more There is very little known about the mechanism of action of these drugs. However, it was shown in 2015 that a possible … See more The silencing of genes created by abnormal DNA methylation is a major contributor to the formation of cancerous tumors. Variations in DNA methylation of normal cells … See more A hypomethylating agent (or demethylating agent ) is a drug that inhibits DNA methylation: the modification of DNA nucleotides by addition of a methyl group. Because DNA methylation affects cellular function through successive generations of cells without changing the underlying DNA sequence, treatment with a hypomethylating agent is considered a type of epigenetic therapy.
