miR-182 is up-regulated in glioma cell lines and glioma tissues. Real-time RT-PCR analysis of miR-182 expression in NHA and glioma cell lines (SNB19, LN18, U87, U118, T98, A172, U138, U251, and U373; A) and in normal brain tissues and glioma tissue samples of different World Health Organization grades (B) is shown. Expression levels were normalized for U6, and the average ratio of miR-182 expression was quantified. Error bars (SD) were calculated from triplicate samples. Statistical significance of *P < 0.05.
