SNHG15 and non-small cell lung carcinoma: In‐vitro assays revealed that decreased SNHG15 expression could obviously impair proliferative capacity of NSCLC cells, cause G0/ G1 phase arrest and increase the ratio of apoptotic NSCLC cells.36, 78 Moreover, downregulation of SNHG15 substantially inhibited the invasive and metastatic ability of NSCLC cells.36, 78 The pro‐metastatic effects of SNHG15 were induced by the regulation of the expression of a number of genes involved in cell metastasis and EMT progress.
