Glioma cell growth and metastasis are impeded in vitro when the lncRNA PTENP1 is overexpressed [27]; according to the study by Wang et al., PDIA3P1, a hypoxia-induced long noncoding RNA, promotes mesenchymal transition in glioblastoma via sponging miR-124-3p [28]. This evidence concerns the gene PTENP1 and central nervous system cancer.
