Documents have reported that long non-coding RNAs (lncRNAs) are involved in tumor progression. Previous study revealed that lncRNA SNHG1 was often elevated in cancer and was linked with poor prognosis in cancer patients. However, its modulatory mechanism has not been fully clarified in gastric cancer (GC). Here, we reported that SNHG1 expression was significantly increased in GC cell lines and tissues. Knockdown of SNHG1 impeded cell growth via disturbing cell cycle distribution and protecting cells from apoptosis. Nevertheless, SNHG1 down-regulation decreased cell invasive ability and reversed epithelial-mesenchymal transition (EMT) phenotype. Mechanismly, it was found that SNHG1 functioned as a competing endogenous RNA to repress miR-140 expression and thereby elevated its down-stream target ADAM10. In summary, SNHG1 promoted GC cell proliferation and invasion via modulating the miR-140/ADAM10 axis. These findings uncovered that lncRNA SNHG1 could be a candidate target for new therapies in GC patients. (C) 2018 Published by Elsevier B.V.
