DLEU1 and glioma: In many cases, DLEU1 acted as an competing endogenous RNA (ceRNA) for a microRNA, such as miR-381 in cervical cancer [7], miR-99b in bladder cancer, miR-490 in endometrial cancer [10], miR-421 in glioma [25], miR-671-5p in osteosarcoma [26], and microRNA-300 in breast cancer [11].
