Lysine-specific histone demethylase 1B (LSD2/KDM1B) represses p53 expression to promote proliferation and inhibit apoptosis in colorectal cancer through LSD2-mediated H3K4me2 demethylation
Figure 3. LSD2 down-regulation inhibits CRC cell proliferation. (A) Western blot showing protein expression of LSD2 and GAPDH (loading control) in HCT-116 and LoVo cells with control or sh-LSD2. (B, C) BrdU/PI assay to detect and quantification of DNA synthesis in HCT-116 and LoVo cells with control or sh-LSD2. **p < 0.01. (D) Cell Counting Kit-8 (CCK8) assay to detect the viability of HCT-116 and LoVo cells with control or sh-LSD2. (E, F) Colony formation assays and quantification in approximately 500 HCT-116 and LoVo cells with control or sh-LSD2. Data were expressed as means ± SEM, **p < 0.01.
