Epithelial apoptosis is an important factor in intestinal ischemia–reperfusion (I/R) injury. Heat shock factor 1 (HSF1) is a classical stress response factor that directly regulates the transcription of heat shock proteins (HSPs) under stress conditions. Although HSPs are involved in protecting the intestine against I/R, the mechanism whereby HSF1 is regulated in I/R is poorly understood. Here, we...
This study investigated the role of Sirtuin 1 (SIRT1)/forkhead box O3 (FOXO3) pathway, and a possible protective function for Icariin (ICA), in intestinal ischemia–reperfusion (I/R) injury and hypoxia–reoxygenation (H/R) injury.Male Sprague–Dawley rats were pretreated with different doses of ICA (30 and 60 mg/kg) or olive oil as control 1 h before intestinal I/R. Caco-2 cells were pretreated with...
