Methyltransferase Reagents
 
Ask A Technical ScientistTranscriptional repression by hypermethylation of promoter regions is a primary means for the inactivation of gene function. Hypermethylation at promoter sites of regulatory genes is often deleterious. For example, p16 is one of the most important cell cycle regulatory proteins. The loss of p16 function leads to cancer progression by allowing unregulated cell proliferation. Hypermethylation-mediated inactivation of the p16 gene has been demonstrated in a wide array of cancers. Approximately 30% to 40% of colon cancer is attributed to hypermethylated p16 alleles.
