Fig. 5From: Antitumor effect of Quercetin on Y79 retinoblastoma cells via activation of JNK and p38 MAPK pathwaysQuercetin causes phosphorylation of c-Jun N-terminal kinase (JNK) and p38 mitogen-activated protein kinase (MAPK) in RB Y79 cells. a and b The RB Y79 cells were treated with various concentrations of Quercetin (0-100 μM) and incubated for 24 h. The levels of phosphorylated (p-)JNK and p38 MAPK were assessed by western blot, GAPDH was used as a loading control. *P < 0.05, **P < 0.01 against control. @P < 0.05 against Quercetin (50 μM) (n = 3)Back to article page
