Hsp27 levels after quercetin or rosmarinic acid treatments in U-87 MG cells. a Western blot analysis demonstrates that quercetin (at final concentrations of 10 and 30 μM) dose dependently decreased Hsp27 expression (mean ± SD, n = 7, **P < 0.01, ***P < 0.001 vs control (C)) b. Western blot analysis demonstrates that rosmarinic acid (at final concentrations of 80 and 215 μM) dose dependently decreased Hsp27 expression (mean ± SD, n = 7, ***P < 0.001 vs control). C control, Q quercetin, RA rosmarinic acid. All data were normalized to GAPDH
