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 2. LSD2 over-expression promotes CRC cell proliferation. (A) Western blot detection of LSD2 and GAPDH (loading control) protein expression in Caco2 and SW1116 cells with control or LSD2. (B, C) BrdU/PI assay to detect and quantify DNA synthesis in Caco2 and SW1116 cells with control or LSD2. **p < 0.01. (D) Cell Counting Kit-8 (CCK8) assay to measure the viability of Caco2 and SW1116 cells with control or LSD2. (E, F) Colony formation assays and quantification in approximately 500 Caco2 and SW1116 cells with control or LSD2. Data were expressed as means ± SEM, **p < 0.01.
