HOXA9 and colorectal adenocarcinoma: We found that overexpression of miR-633 obviously reduced cell proliferation and promoted apoptosis (all p < 0.01), while co-transfection of miR-633 mimics and pcDNA-HOXA9 significantly attenuated the inhibitory effect of miR-633 mimics in colorectal adenocarcinoma progression (all p < 0.05, Figure 7a-c).
