1 Western blot data revealed that H2O2 upregulated phosphorylation of c-Jun N-terminal kinase (JNK) and p38 mitogen-activated protein kinase (MAPK), which was rapidly reversed by quercetin within 30 min; H2O2 activation of c-Jun was downregulated. Quercetin mitogen-activated protein kinase 8 Homo sapiens

3 These results reveal that quercetin blocks JNK- and p38 MAPK-related signaling triggered by the oxidant and may regulate expression of apoptotic downstream genes, preventing apoptosis and promoting cell survival. Quercetin mitogen-activated protein kinase 8 Homo sapiens
