Quantitation and correlation of miR-210-3p levels with hypoxia markers VEGF and CA9. The graph showing levels of miR-210 (a) and VEGF, CA9 (b) in normal and GBM tumor tissue (n = 30) samples using qRT-PCR. Correlation between miR-210-3p and VEGF (c) and miR-210-3p and CA9 (d) in GBM tumor tissues. The miR-210-3p levels have been normalized with RNU6B, while GAPDH was used for VEGF and CA9 normalization. The graphical data points in a and b represent mean ± S.D. of at least three independent experiments. (*P > 0.01 and < 0.05; **P < 0.01). Error bars denote ± S. D.
