1 Curcumin, but not PD98059 or SB203580, inhibited IL-1 beta-mediated suppression of nuclear RXR:RAR binding activity, which correlated with inhibition of JNK phosphorylation and phospho-JNK-mediated phosphorylation of RXR. Curcumin mitogen-activated protein kinase 8 Homo sapiens
2 Curcumin, but not PD98059 or SB203580, inhibited IL-1 beta-mediated suppression of nuclear RXR:RAR binding activity, which correlated with inhibition of JNK phosphorylation and phospho-JNK-mediated phosphorylation of RXR. Curcumin mitogen-activated protein kinase 8 Homo sapiens
3 Taken together, these data provide evidence supporting a novel player (JNK), as well as its inhibitor (curcumin), in inflammation-mediated regulation of hepatobiliary transporters and correlate JNK-dependent RXR phosphorylation with reduced RXR-dependent hepatic gene expression. Curcumin mitogen-activated protein kinase 8 Homo sapiens
