LINC00313/miR-4429 axis provides novel biomarkers for the diagnosis and prognosis of non-small cell lung cancer
Background: Increasing evidence suggests that the LncRNA/miRNA axis plays a key role in many types of tumorigenesis. However, the potential role and clinical value of LINC00313/miR-4429 in non-small cell lung cancer (NSCLC) remain elusive and need further study. The aim of this study was to investigate the role of LINC00313/miR-4429 axis in NSCLC. Methods: The expression of LINC00313 and miR-4429 in serum, tissues and cell lines of NSCLC patients were detected by reverse transcription-quantitative PCR. The diagnostic value was evaluated by receiver operating characteristic (ROC) curve analysis and the prognostic value was analyzed by Kaplan-Meier survival analysis and Cox regression. Result: The expression of LINC00313 was significantly up-regulated while the expression of miR-4429 was down-regulated in NSCLC serum, tissue and cell lines. A negative correlation was found between LINC00313 and miR-4429 in patients with NSCLC. ROC curves showed that LINC00313 and miR-4429 had high diagnostic value and Kaplan-Meier curve results showed that high expression of LINC00313 and low expression of miR-4429 predicted poor prognosis. Conclusion: In summary, our data show that the ectopic expression of LINC00313 and miR-4429 has promising clinical significance in the diagnosis and prognosis of NSCLC. The LINC00313/miR-4429 axis may provide novel biomarker for NSCLC treatment.
