Small ubiquitin-like modifier 4 (SUMO4) is the latest member of the sumoylation family, which enhances the stability of protein, regulates the distribution and localization of the protein, and affects the transcription activity of the protein. However, the role of SUMO4 in non-small cell lung cancer (NSCLC) has not yet been reported. The present study first demonstrated that SUMO4 was upregulated in a number of tissues from patients with NSCLC. Immunohistochemistry was performed to demonstrate the expression level of SUMO4 in lung cancer tumor tissues. Following the transfection, The EMT status and signaling pathway activation regulated by SUMO4-siRNA was assessed by western blotting. The Transwell and wound healing assays were performed to investigate the regulatory effect of SUMO4-siRNA on cell migration and invasion. Cell Counting Kit-8 assay was performed to investigate whether SUMO4-siRNA affected the chemosensitivity of the NSCLC cells to cisplatin. Statistical analysis of immunohistochemical results from the tissues showed that the overexpression of SUMO4 was significantly associated with sex, tumor type, history of smoking, T stage and poor prognosis. It was also identified that SUMO4 small interfering RNA attenuated invasion and migration in NSCLC cell lines, as well chemosensitivity to cisplatin via the inhibition of the JAK2/STAT3 pathway. In conclusion, SUMO4 may play an important role in the poor prognosis of patients with NSCLC. The present study indicates that SUMO4 may be a potential therapeutic target for NSCLC.
