To analyze DDB2 regulation of TGFB2 in other cancer cells, we compared the expression of the TGFB2 mRNA in colon adenocarcinoma cell lines HCT116:sh-Control and HCT116:sh-DDB2 cells, and observed a 3-fold induction in HCT116:sh-DDB2 cells (data not shown). This evidence concerns the gene TGFB2 and cancer.
