Downregulated expression of hsa_circ_0037515 and hsa_circ_0037516 as novel biomarkers for non-small cell lung cancer.

Abstract

mRNA, hsa_circ_0037515, and hsa_circ_0037516 are significantly downregulated in 61 paired samples of NSCLC compared to adjacent lung tissues (P < 0.01), and that the areas under the ROC curves for the two circRNAs (0.81 and 0.82, respectively) are indicative of diagnostic value. Furthermore, the significance was improved by considering the two circRNAs in combination (area under the ROC curve, 0.90). Our results suggest that hsa_circ_0037515 and hsa_circ_0037516 serve as novel potential biomarkers for the diagnosis of NSCLC.
