Accumulating evidence has identified microRNA-1179 (miR-1179) as a novel cancer-related miRNA that is dysregulated in multiple cancers and plays an important role in regulating cancer development and progression. However, little is known about the role of miR-1179 in non-small cell lung cancer (NSCLC). Thus, in the present study, we aimed to investigate the potential biological function and regulatory mechanism of miR-1179 in NSCLC. The results showed that decreased expression of miR-1179 expression was frequently detected in primary NSCLC tissues and cell lines. Overexpression of miR-1179 suppressed the growth and invasion of NSCLC cells in vitro while its inhibition promoted the opposite effect. Sperm associated antigen 5 (SPAG5) was an identified as a target gene of miR-1179. Moreover, SPAG5 expression was increased in NSCLC cells and showed an inverse correlation with miR-1179 in NSCLC specimens. SPAG5 knockdown inhibited the growth and invasion of NSCLC cells, results that simulated a similar effect to miR-1179 overexpression. Mechanistic investigations showed that miR-1179 overexpression or SPAG5 knockdown significantly downregulated the activation of Akt signaling. Additionally, SPAG5 overexpression partially reversed the antitumor effect of miR-1179. Overall, our results demonstrated that miR-1179 inhibited the growth and invasion of NSCLC cells by targeting SPAG5 and inhibiting Akt, findings that highlight the importance of the miR-1179/SPAG5/Akt axis in the progression of NSCCL.
