Oncogenic roles of SETDB2 histone methyltransferase in gastric cancer

ABSTRACT: Histone H3 lysine 9 tri-methyltransferases (H3K9me3) are related to transcriptional gene silencing. Although SETDB2 has H3K9me3 activity, it is unknown whether SETDB2 is linking to carcinogenesis. Here, we studied alterations and functions of SETDB2 in gastric cancers (GCs). In human clinical samples, overexpression of SETDB2 protein was observed in 30 of 72 (41.7%) primary GC tissues compared with their normal counterparts, and significantly associated with poor prognosis of the patients (P<0.05). SETDB2 protein was significantly detected in late stage of GCs. Moreover, SETDB2 protein was strongly expressed in four (30.8%) of 13 GC cell lines, and knockdown of SETDB2 led to decrease the cell proliferation, migration and invasion. According to the microarray analysis on a GC cell line afte
