TGFB1 and neoplasm: Such lncRNAs are frequently overexpressed in diverse human tumors, as for example the lncRNA-MUF/LINC00941 and LINC01711 that are overexpressed in glioblastoma tumors, both being highly regulated by TGFβ signaling, and acting as sponges/competing endogenous RNAs to the miRNA miR-34a, a negative regulator of transcription factors SNAI1 and ZEB1, thus promoting tumor cell invasiveness [14, 15].
