Abstract
Curcumin has been extensively studied for its therapeutic effects in a variety of disorders. Fermented soy consumption is associated with a low incidence rate of chronic diseases in many Asian countries. The aim of this study was to investigate the potential underlying mechanisms of the effect of a phyto-power dietary supplement on liver fibrosis. Sprague-Dawley rats were intraperitoneally injected with dimethylnitrosamine (DMN; 10 mg kg-1) three times a week for four consecutive weeks. A phyto-power dietary supplement (50 or 100 mg kg-1) was administered by oral gavage daily for four weeks. Liver morphology, function, and fibrotic status were examined in DMN induced hepatic fibrogenesis. However, a phyto-power dietary supplement alleviated liver damage as indicated by histopathological examination of the α-smooth muscle actin (α-SMA) and collagen I, accompanied by the concomitant reduction of transforming growth factor-β1 (TGF-β1) and matrix metalloproteinase 2 (MMP2). These data indicate that the phyto-power dietary supplement may inhibit the TGF-β1/Smad signaling and relieve liver damage in experimental fibrosis. © 2013 The Royal Society of Chemistry.
