ABSTRACT
Curcumin has the potential to treat inflammatory diseases. This study investigated its effect on sepsis-induced acute lung injury (ALI) in a rat model. 125 healthy rats were randomly divided into five groups, including normal group, sham-operated group, sepsis group, dimethyl sulfoxide group, and curcumin-treated group (25 rats in each subgroup). Sepsis-induced acute lung injury was affected by cecal ligation and puncture surgery. At 0, 6, 12, 24, and 48 h after treatment, the lungs were harvested for histological and protein expression examinations. 24h after the initial treatment, real-time PCR and Western blot analysis showed that the expression of TGF-ß1 and SMAD3-dependent signaling pathway was significantly decreased in the curcumin-treated group than other control groups (P<0.05). Therefore, curcumin played a protective role in sepsis-induced ALI, possibly through the inhibition of the expression of TGF-ß1/SMAD3 pathway which may provide a new strategy for the treatment of sepsis-induced ALI.
