Chemotherapy and radiation therapy probably cause epigenetic changes in the pattern of DNA methylation and changes in the levels of transcripts of several genes in the tissues of invasive cervical cancer—after treatment methylation of the promoters of the BAX, BRCA1, and ESR1 genes increased significantly, while the expression of transcripts of the MYOD1 and MLH1 genes was significantly reduced [40]. This evidence concerns the gene BAX and cervical carcinoma.
