Analysis of RBAT1 expression in tissue samples and plasma. RBAT1 and miR-27b expression in paired EC and non-tumor samples from advanced EC patients (A) and plasma samples (B) from EC patients and healthy controls was analyzed with RT-qPCR. RBAT1 and miR-27b in EC tissues (C) and plasma samples (D) were compared between DR and Non-DR groups. E Correlations between the expression levels of RBAT1 and miR-27b were analyzed using Pearson’s correlation coefficient. **, p < 0.01
