摘要: The term epigenetics is used to describe the study of stable and heritable alterations in gene expression potential that arise during development cell proliferation. Two epigenetic mechanisms have been thoroughly investigated past few years: DNA methylation histone modifications. failure maintenance these marks can lead inappropriate activation or inactivation signaling pathways result disease, such as cancer. Promoters tumor suppressor genes assessed for hypermethylation with a variety techniques, both at specific loci genome wide. Methylation MGMT gene, which favors treatment results temozolomide, clear example influence astrocytomas. At clinical level, emphasis now on combining inhibitors methyl transferases deacetylases.
