Environmental Exposure, DNA Methylation, and Gene Regulation

Abstract excerpt

DNA methylation is an epigenetic mechanism that regulates chromosomal stability and gene expression. Abnormal DNA methylation patterns have been observed in many types of human tumors, including those of the breast, prostate, colon, thyroid, stomach, uterus, and cervix. We and others have shown that exposure to a wide variety of xenobiotics during critical periods of mammalian development can persistently alter...
