1 Quercetin augments TRAIL-induced apoptotic death: involvement of the ERK signal transduction pathway. Quercetin mitogen-activated protein kinase 1 Homo sapiens
2 We hypothesized that quercetin-induced activation of MAPK (ERK, p38, JNK) is responsible for downregulation of survivin gene expression. Quercetin mitogen-activated protein kinase 1 Homo sapiens
3 We hypothesized that quercetin-induced activation of MAPK (ERK, p38, JNK) is responsible for downregulation of survivin gene expression. Quercetin mitogen-activated protein kinase 1 Homo sapiens
4 To test this hypothesis, we selectively inhibited MAPK during treatment with quercetin. Quercetin mitogen-activated protein kinase 1 Homo sapiens
5 Our data demonstrated that inhibitor of ERK (PD98059), but not p38 MAPK (SB203580) or JNK (SP600125), significantly maintained the intracellular level of survivin during treatment with quercetin. Quercetin mitogen-activated protein kinase 1 Homo sapiens
6 Quercetin-induced activation of the ERK-MSK1 signal transduction pathway may be responsible for deacetylation of histone H3. Quercetin mitogen-activated protein kinase 1 Homo sapiens
7 Taken together, our findings suggest that quercetin enhances TRAIL induced apoptosis by inhibition of survivin expression, through ERK-MSK1-mediated deacetylation of H3. Quercetin mitogen-activated protein kinase 1 Homo sapiens
