Gayban, A.J.B. (author), Souza, L.A.C. (author), Cooper, S.G. (author), Regalado, E. (author), Kleemann, R. (author), Earley, Y.F. (author)Non-alcoholic fatty liver disease (NAFLD) comprises a spectrum of liver damage directly related to diabetes, obesity, and metabolic syndrome. The (pro)renin receptor (PRR) has recently been demonstrated to play a role in glucose and lipid metabolism. Here, we test the hypothesis that the PRR regulates the development of diet-induced hepatic...article 2023

(author)Cardiovascular disease (CVD) is closely associated with obesity through risk factors such as dyslipidemia and chronic low-grade inflammation, which may be affected by diet. Dietary fats have been extensively studied in relation to CVD risk, however these studies have not always yielded consistent results, most likely due to lack in control of...article 2023

In addition to indicating systemic inflammation, it is suggested that CRP itself can play a role in OA development. Obesity and metabolic syndrome are important risk factors for OA and also induce elevated CRP levels. Here we evaluated in a human CRP ...article 2019
