BRD4 and colorectal cancer: Furthermore, we examined the expression of BRD4 in 9 human colorectal cancer cell lines(HCT116, LoVo, RKO, Caco2, HT29, SW48, SW480, SW620, and DLD1 cells) and normal colorectal epithelial cell FHC, which also indicated the same result that BRD4 was overexpressed in human colorectal cancer cells (Figure 1.D).
