Expression levels of miR-320 and survivin mRNA in NSCLC tissues were also measured by performing qPCR. The effects of HCP5, miR-320 and survivin overexpression on the proliferation of H23 cells were analyzed by cell proliferation assay.Results: We found that HCP5 was up-regulated in NSCLC and predicted the poor survival of NSCLC patients. HCP5 was negatively correlated with miR-320 but positively correlated with survivin in NSCLC tissues. In NSCLC cells, HCP5 overexpression led to the up-regulated survivin and down-regulated miR-320. Moreover, miR-320 overexpression failed to affect HCP5 but down-regulated survivin. Cell proliferation assay showed that HCP5 and survivin overexpression led to increased, while miR-320 overexpression led to decreased cell proliferation rate. In addition, miR-320 overexpression reduced the effects of HCP5 overexpression.Conclusion: Therefore, HCP5 may stimulate the proliferation of NSCLC cells by up-regulating survivin through the down-regulation of miR-320.Keywords: HCP5, non-small cell lung cancer, miR-320, survivin
