Abstract:
... The Euterpe oleracea Mart. (açaí) seed extract (ASE), rich in polyphenols, has been evidenced as a potential regulator of body mass with antioxidant and anti-inflammatory actions. We aimed to assess the effects of ASE and enalapril (ENA) on the hepatic steatosis and fibrosis and related overexpressed RAS, oxidative stress and inflammation in C57BL/6 mice fed a high-fat diet (HFD). The animals were ...

Abstract:
... Lignin is a polymer of phenylpropanoid compounds formed through a complex biosynthesis route, represented by a metabolic grid for which most of the genes involved have been sequenced in several plants, mainly in the model-plants Arabidopsis thaliana and Populus. Plants are exposed to different stresses, which may change lignin content and composition. In many cases, particularly for plant-microbe ...
