There are several common ways to determine whether a gene contains methylated DNA. Since mammalian methylation occurs at cytosines, researchers take advantage of the fact that methylated cytosine (meC) is stable to bisulfite treatment but unmethylated cytosine is transformed to
Epigenetics is a term coined to describe changes that are not mutation based but can still be passed on from generation to generation. Genes that are activated or repressed without any change in DNA sequence are epigenetically controlled. Epigenetic modifications
The overall degree of methylation of a genome can be a useful measure of global regulatory changes. Measurement of this parameter is usually performed after complete digestion to the single base and then analyzed using HPLC or mass spectrophotometry. The
Cancer research has revealed that the classical model of carcinogenesis, a three step process consisting of initiation, promotion, and progression, is not complete.
