MiR-31-5p was upregulated in OC and inversely correlated with miR503HG. qPCR was performed to measure the expression levels of miR-31-5p in both OC and non-tumor biopsies from the 61 OC patients included in this study. Differences in expression levels between OC and non-tumor biopsies were explored using paired t test. Expression levels of miR-31-5p were significantly higher in OC than in non-tumor tissues (a). Correlations between miR-31-5p and miR503HG across both OC (b) and non-tumor (c) tissues were analyzed by linear regression. PCR reactions were repeated 3 times and mean values were presented, p < 0.05
