Abstract
- Oxidative stress and inflammation play a central role in the progression of nonalcoholic steatohepatitis (NASH), which can lead to liver cirrhosis. Barley bran has potential bioactivities due to its high content of functional substances, such as anthocyanins, with anti-inflammatory and anti-oxidative properties. Here, we investigated whether barley bran polyphenol-rich extracts (BP) can prevent NASH in Sprague–Dawley rats fed a high-fat and high-cholesterol diet including 1.25% or 2.5% cholesterol for 9 weeks. In the rat model of NASH with advanced hepatic fibrosis, BP prevented NASH development by ameliorating the histopathological findings of lobular inflammation. The BP also tended to attenuate serum aspartate aminotransferase level in this model. In the rat model of NASH with mild-to-moderate hepatic fibrosis, BP tended to attenuate the serum levels of transaminases. BP-dose-dependent effects were revealed for several parameters, including monocyte chemoattractant protein-1, transforming growth factor-β, and manganese superoxide dismutase gene expressions in the liver. These results suggest that BP may prevent NASH development or progression, presumably due to its anti-inflammatory and anti-oxidative properties.
