Interestingly, the differentially methylated probe (DMP) for both C1 vs. C3 and C2 vs. C3 contained cg07810039 (TGFB2) (Figures 4M, N), whose down-regulation of methylation levels may affect the expression and function of the TGFB2 gene, and consequently the growth and metastasis of breast cancer cells. Here, TGFB2 is linked to breast cancer.
