Abstract
We have previously shown that diallyl disulfide (DADS) protects mice against cerulein-induced acute pancreatitis (AP) and associated lung injury. However, the molecular mechanisms underlying its effect and the components involved have not been studied. We hypothesized that DADS may reduce TNF-α, CSE expression, H2S production, STAT3, and NF-κB activation and induce SOCS3 expression through peroxisome proliferator-activated receptor γ (PPAR-γ) pathway in cerulein-induced mice. Male Swiss mice were treated with hourly intraperitoneal injections of cerulein (50 µg/kg) for 6 h. Diallyl disulfide (200 μg/kg) was administered in the presence or absence of PPAR-γ antagonist GW9662 (0.3 mg/kg) (i.p) 1 h after the induction of AP. Our findings revealed that DADS blocked TNF-α, CSE expression, H2S production, and STAT3, and NF-κB activation was reversed by GW9662. Furthermore, GW9662 abrogated DADS-induced SOCS3 expression. The results show for the first that DADS-induced anti-inflammatory effect in acute pancreatitis is regulated through PPAR-γ.
