CASC9 and cervical cancer: Comparable “ceRNA” mechanisms have been identified in other cancers: the LINC00152/miR-205-5p/CXCL-11 pathway in liver cancer (58); the NORAD/miR-496/IL-33 pathway in gastric cancer (56); the LINC00355/miR-34b-5p/ABCB1 pathway in bladder cancer (74); the CASC9/miR-215/TWIST2 pathway in cervical cancer (66); the TUC338/miR-8485/CBX2 pathway in laryngeal squamous cell carcinoma (52); and the lnc003875/miR-363/EGR1/Ang-1 pathway in placental site trophoblastic tumor (90).
