About Epigenetics
Epigenetics refers to changes in the regulation of gene expression, and DNA methylation and histone deacetylation are two of the more studied epigenetic regulators of gene expression. Epigenetic changes can silence gene expression and, unlike DNA mutations, may be reversed by targeting the enzymes involved. The silencing of key cell cycle control genes and tumor suppressor genes through these two mechanisms of epigenetic regulation has been demonstrated in vitro and in vivo in hematological malignancies and in solid tumors. These key growth control genes can be re-expressed in cancer cells when DNA hypermethylation is reversed by Vidaza and/or inappropriate histone deacetylation is inhibited by MGCD0103. Rather than using molecules that kill both normal and tumor cells, as do traditional anticancer agents, targeted epigenetic therapy reactivates the silenced tumor suppressor genes thereby re-establishing the cancer cell's natural mechanisms to control abnormal growth.
