Role of circular RNAs (CircANXA2 and CircFBXW7) in bladder cancer

Abstract

Abstract Background The most prevalent malignancy in the urinary tract is bladder cancer, which is becoming more commonplace globally. Circular RNAs, or circRNAs, have a role in cancer pathogenesis as they can be used as biomarkers to help identify new cases and predict the likelihood of recurrence. The current work examined the gene expression of CircANXA2 and CircFBXW7 and evaluated their potential utility in bladder cancer diagnosis. Subjects and methodology Seventy people with benign urologic diseases, seventy people with bladder cancer, and seventy healthy controls participated in the study. The polymerase chain reaction in real time quantified the gene expressions of CircANXA2 and CircFBXW7. Results Compared to the benign group and controls, bladder cancer patients had significantly greater levels of CircANXA2 expression (p < 0.001). In contrast to the benign group and controls, bladder cancer patients had significantly decreased levels of CircFBXW7 expression (p < 0.001). CircANXA2 and CircFBXW7 have comparable sensitivity and specificity; CircANXA2 had sensitivity, and specificity (77.14% and 76.43) and CircFBXW7 had sensitivity, and specificity (80.0% and 70.0%) respectively in detecting bladder cancer. CircANXA2 and CircFBXW7 were found to be the risk variables for bladder cancer using multivariate analysis. The odds ratios (OR) for CircANXA2 and CircFBXW7 were 1.240 (1.135–1.354) and 0.026 (0.006–0.107), in that order. In conclusion, CircANXA2 and CircFBXW7 may be highly specific and sensitive diagnostic markers for bladder cancer.
