    Abstract:
    Far less has been unveiled about the functions of lncRNAs on cancers yet. Here, we reported that lncRNA FAM87A, as a ceRNA of miR-424-5p, played a vital role in glioma development. qRT-PCR result indicated that FAM87A was abnormally downregulated in glioma tissue and cells. Survival analysis suggested that the FAM87A expression was negatively correlated with the survival rate. Effects of FAM87A on human glioma cell lines were also analyzed by MTT, Edu, and transwell assays. FAM87A hastened proliferation and migration of glioma cells. MiR-424-5p, predicted target of FAM87A, was fostered in glioma, which was examined by qRT-PCR. A negative correlation was indicated between FAM87A and miR-424-5p. Results of bioinformatics, dual luciferase, and RIP assays unveiled that FAM87A and miR-424-5p act upon each other. In addition, miR-424-5p targeted 3'-UTR of PPM1H. Also, effects of miR-424-5p/FAM87A on glioma cells were identified via the cell function experiments. FAM87A suppressed PPM1H by binding to miR-424-5p competitively, thereby restraining cell proliferation, migration, and invasion. Collectively, these findings illuminated a new mechanism for glioma progression. Therefore, FAM87A may act as a feasible target for glioma treatment.
