TGFB1 and glioblastoma: Moreover, lncRNA-MUF could upregulate the effect of TGF-β inducing CAPRIN2 expression in a cis manner, apart from sponging miR-34a, which targets SNAI1. Nevertheless, although in the absence of lncRNA-MUF, the levels of SMAD2/3 phosphorylation, the mRNA levels of vimentin, connective tissue growth factor, and MYC, and the invasiveness phenotype were reduced in GBM cells.
