additional information | Jmjd2b knockdown by siRNA, leading to induction of p53 via activation of the DNA damage response pathway. p53 Inhibition significantly restored the clonogenic potential of AGS and HeLa cells treated with JMJD2B siRNA. Increased apoptosis in BGC-823 and HeLa cells but not AGS cells with JMJD2B siRNA knockdown. AGS cells are arrested at the G1 phase, but BGC-823 and HeLa cells are arrested at the S phase | Homo sapiens |

malfunction | knocking down JMJD2B expression by siRNA in gastric and other cancer cells inhibits cell proliferation and/or induces apoptosis and elevates the expression of p53 and p21CIP1 proteins, mechanism of JMJD2B inhibition, overview. The enhanced p53 expression results from activation of the DNA damage response pathway | Homo sapiens |
physiological function | histone demethylase JMJD2B regulates chromatin structure or gene expression by removing methyl residues from trimethylated lysine 9 on histone H3 and is required for tumor cell proliferation and survival in vitro and in vivo, and is overexpressed in gastric cancer | Homo sapiens |
