Emodin protects against severe acute pancreatitis-associated acute lung injury by activating Nrf2/HO-1/GPX4 signal and inhibiting ferroptosis in vivo and in vitro.

ABSTRACT:

Background

Severe acute pancreatitis (SAP) has high morbidity, a complicated and dangerous course, and many complications, including severe pulmonary complications. SAP-associated acute lung injury (SAP-ALI) is still a significant challenge for surgeons because of its high mortality. Therefore, more effective treatment methods are urgently needed. Emodin (EMO) has shown tremendous potential in treating many refractory diseases. However, its protection mechanism in SAP-ALI needs to be further clarified. This study was undertaken to investigate the protective effects of EMO against lung injury in SAP rats and alveolar epithelial cells, with a particular focus on the classical ferroptosis pathway.

Methods

In an in vivo study, forty SD rats were evenly split into five groups: sh
