BCL2 and colorectal carcinoma: Cell apoptosis involved in IRF6 expression in CRC cells was further explored in our study, results of which showed that IRF6-OE strengthened the sensitivity of CRC cell to cisplatin observably which was similar to results of Tunel staining in CRC tissues with/without chemotherapy and confirmed by protein expression assay for cell proliferation and apoptosis-related markers as BAX, Bcl2 and caspase-3 (cleaved caspase-3).
