BACKGROUND: Long non-coding RNAs (lncRNAs) have emerged as critical regulators of
tumor progression. However, the role and molecular mechanism of lncRNA XIST in
gastric cancer is still unknown. METHODS: Real-time PCR analysis was performed to
measure the expression levels of lncRNA XIST in gastric cancer tissues and cell
lines, the correlation between lncRNA XIST expression and clinicopathological
characteristics and prognosis was analyzed in gastric cancer patients. The
biological function of lncRNA XIST on gastric cancer cells were determined both
in vitro and in vivo. The regulating relationship between lncRNA XIST and miR-101
was investigated in gastric cancer cells. RESULTS: lncRNA XIST was significantly
up-regulated in gastric cancer tissues and cell lines. Overexpression of lncRNA
XIST was markedly associated with larger tumor size, lymph node invasion, distant
metastasis and TNM stage in gastric cancer patients. Functionally, knockdown of
lncRNA XIST exerted tumor-suppressive effects by inhibiting cell proliferation,
migration and invasion in vitro and tumor growth and metastasis in vivo.
Furthermore, an inverse relationship between lncRNA XIST and miR-101 was found.
Polycomb group protein enhancer of zeste homolog 2 (EZH2), a direct target of
miR-101, could mediated the biological effects that lncRNA XIST exerted.
CONCLUSIONS: lncRNA XIST is up-regulated and is associated with aggressive tumor
phenotypes and patient survival in gastric cancer, and the newly identified
lncRNA XIST/miR-101/EZH2 axis could be a potential biomarkers or therapeutic
targets for gastric cancer patients.
