1 Celastrol induces expression of heme oxygenase-1 through ROS/Nrf2/ARE signaling in the HaCaT cells. celastrol NFE2 like bZIP transcription factor 2 Homo sapiens
2 Celastrol induced Nrf2 activation. celastrol NFE2 like bZIP transcription factor 2 Homo sapiens
3 Nrf2 knockdown using small interfering RNA (siRNA) inhibited celastrol-induced HO-1 expression. celastrol NFE2 like bZIP transcription factor 2 Homo sapiens
4 Furthermore, Nrf2 siRNA significantly reversed the inhibitory effect of celastrol on IFN-gamma-induced expression of ICAM-1 in the keratinocytes. celastrol NFE2 like bZIP transcription factor 2 Homo sapiens
5 Taken together, our results indicate that celastrol can activate the ROS-ERK/p38-Nrf2-ARE signaling cascades leading to the up-regulation of HO-1 which is partly responsible for its anti-inflammatory activity in the keratinocytes. celastrol NFE2 like bZIP transcription factor 2 Homo sapiens
