Deletion 101 residue at caveolin-1 scaffolding domain peptides impairs the ability of increasing heme oxygenase-1 activity.

Objective: Resident alveolar macrophages (AMs) are activated and release proinflammatory mediators and chemokines during acute lung injury. We have previous reported that caveolin-1 (Cav-1) scaffolding domain (CSD) peptide inhibited the proinflammatory cytokines expression by up-regulating heme oxygenase-1 (HO-1) activity. In this study, we aimed to investigate the effect of residue R101 in CSD peptide on the activity of HO-1 in AMs.

Caffeic acid phenethyl ester attenuates ionize radiation-induced intestinal injury through modulation of oxidative stress, apoptosis and p38MAPK in rats.

Caffeic acid phenyl ester (CAPE) is a potent anti-inflammatory agent and it can eliminate the free radicals. This study aimed to investigate the radioprotective effects of CAPE on X-ray irradiation induced intestinal injury in rats. Rats were intragastrically administered with 10 μmol/kg/d CAPE for 7 consecutive days before exposing them to a single dose of X-ray irradiation (9Gy) to abdomen.
