Methylation is negative correlation with genetic transcription , and the mechanism is probably as follows : directly interfere the combination of specific transcripton and recognition site of each promoter ; mediated transcription inhibition by change the construction of chromatin; induced gene silencing by combination of methylation site and transcription inhibition. P16 gene is also called multiple tumor supresser gene , which is the best easily to methylate in the anti-oncogenes. P16 gene locates in 9p21 of mankind-chromatosome , and it's total length is 8.5kb .

Ransforming growth factor beta TGF-β is a potent growth suppressor of normal epithelial cells. However, many types of invasive cancer cells (e.g. breast cancer frequently overproduce TGF-β to enhance their growth and metastasis. Quite frequently, these cells do not possess a functional type II TGF-β receptor, indicating an aberrant TGF-β signaling is responsible for promoting cell growth.
