Gastric cancer was the third cause of death in China. In this study, we found
that the APOBEC3 (apolipoprotein B mRNA-editing enzyme, catalytic
polypeptide-like 3) expression was higher in gastric cancer tissues than that in
normal tissues and confirmed APOBEC3B expression was correlated with the
unfavorable prognosis of the patients with gastric cancer. Furthermore, APOBEC3B
expression was associated with gender, tumor size, histological grade, T stage,
and TNM staging of the patients with gastric cancer. Down-regulation of APOBEC3B
expression in MNK28 cells could enhance the cytotoxicity of PDCD2. No editing
took place in PDCD2 positive MKN28 cells with APOBEC3B shRNA. These results
indicated that loss of function of PDCD2 may be partly caused by APOBEC3B-induced
extensive mutagenesis.
