Overexpression of YEATS4 contributes to malignant outcomes in gastric carcinoma.

ABSTRACT: YEATS domain containing 4 (YEATS4) has functions of chromatin modification and transcriptional regulation and is in a gene-amplified region (12q13) in various human cancers. In this study, we tested whether YEATS4 acts as a cancer-promoting gene through its activation/overexpression in gastric cancer (GC). We analyzed 5 GC cell lines and 135 primary tumor samples of GC, which were curatively resected in our hospital. Overexpression of the YEATS4 protein was frequently detected in GC cell lines (5/5 cell lines, 100%) and primary GC tumor tissues (32/135 cases, 23.7%). Knockdown of YEATS4 inhibited proliferation, migration and invasion of GC cells through NOTCH2 down-regulation in a TP53 mutation-independent manner, and induced apoptosis in wild-type TP53 GC cells. Moreover, kn
