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 4. LSD2 promoted CRC cells proliferation in vivo. (A) Effects of LSD2 down-expression on tumor growth in a xenograft mouse model. Empty vector or sh-LSD2 was transfected into LoVo cells, which were injected in the nude mice (n = 6), and the tumors were obtained at day 35 and was determined by measuring their tumor volume (B) and tumor weight (C). Data were expressed as means ± SEM. (D) The tumor sections were under IHC staining using antibodies against LSD2, p53, p21,ki-67, *P < 0.05.
