Iso-alpha-acids (IAAs) are hops-derived compounds. In this study, the authors show that IAAs inhibit development of non-alcoholic fatty liver disease. They found that IAAs reduced expression of PPAR-γ and key enzymes of lipid synthesis as well as increased expression of PPAR-α, indicative of increased lipid metabolism. IAAs also reduced oxidative stress and JNK-activation, inhibited hepatic stellate cell activation and reduced proliferation and pro-fibrogenic gene expression.
