The role of estrogen receptor subtypes in ameliorating hepatic injury following trauma-hemorrhage

Although both PPT and DPN decreased hepatic injury following trauma-hemorrhage, ER-α agonist PPT appears to be more effective in downregulating NF-κB and AP-1 activity, and iNOS induction. Thus, ER-α appears to play a predominant role in mediating the salutary effects of E2 in ameliorating hepatic damage following trauma-hemorrhage.
