HOTAIRM1 expression is high in glioma tissues and cells. A qRT-PCR was used to detect HOTAIRM1 expression levels in normal human astrocyte NHA cells and glioma cell lines U87 and U251. B qRT-PCR examined HOTAIRM1 expression level in glioma tissue samples (n = 12 in each group). GAPDH was used as a reference control. Data are presented as the mean ± SD of three independent experiments (n = 3). **P < 0.01, ***P < 0.001
