Consistently, BDNF silencing had the same effects as miR-210 overexpression in glioblastoma, and upregulation of BDNF counteracted the inhibitory effect of miR-210 in glioblastoma.
Overall, our study reveals a novel miRNA signature of hypoxia in GBM and suggests miR-210-3p to be an oncogenic player and a novel potential intrinsic marker of hypoxia in glioblastoma.
