Long non-coding RNA SNHG1 is an unfavorable prognostic factor and promotes cell proliferation and migration by Wnt/β-catenin pathway in epithelial ovarian cancer.
International journal of clinical and experimental pathology(2017)
Abstract
Long non-coding RNAs (lncRNA) have been shown to serve critical roles in human cancers development, including epithelial ovarian cancer (EOC). Here, we identified a novel lncRNA SNHG1, which was markedly upregulated in human EOC tissues and cell lines. High SNHG1 expression was associated with aggressive clinical features and poor prognosis of EOC patients. Moreover, the downregulation of SNHG1 remarkably inhibited the EOC cells proliferation, migration and invasion, suppressed S-phase entry in vitro, and repressed tumor growth in vivo. In contrast, overexpression of SNHG1 could promote the aggressive behaviors of EOC cells. Furthermore, through western blot, we found that SNHG1 enhanced the expression of several downstream genes in Wnt/β-catenin pathway. Our findings demonstrated that the dysregulation of SNHG1 is implicated in EOC tumorigenesis and progression through regulating Wnt/β-catenin pathway.
