Previous studies have shown that some lncRNAs, such as TUG1, UCA1, and AFAP1-AS1, regulated the expression of miR-145 by a sponging mechanism in glioma stem cells (GSCs) [41], nasopharyngeal carcinoma (NPC) cell lines [42], and OSCC cell lines [43], respectively. Here, UCA1 is linked to nasopharyngeal carcinoma.
