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 1. LSD2 expression levels in human colorectal cancer (CRC) tissue and cells. (A) The ONCOMINE database was used to examine mRNA expression of LSD2 in CRC tissue. (B) Real-time Polymerase chain reaction (PCR) to evaluate mRNA expression of LSD2 in clinical CRC specimens relative to normal tissues (n=36). Data were expressed as means ± SEM. (C, D) Western Blot evaluation of LSD2 protein expression in CRC and normal tissue. (E) LSD2 protein expression in normal and CRC tissue was analysed by IHC. (F) Pearson’s χ2 tests to assess the association between colon tissue type and LSD2 expression by IHC(n=36). (G) Western blotting to assess LSD2 expression in CRC cell lines.
