Epidemiological studies have shown that caffeine increases plasma SHBG levels and also reduce the risk of type 2 diabetes. There are no reports describing any molecular mechanism by which caffeine regulates hepatic SHBG production. The aim of the present study was to explore whether caffeine regulates SHBG production and to determine the associated molecular mechanisms. For this purpose, in vitro and in vivo studies were performed using human HepG2 cells and ...

Sex hormone-binding globulin (SHBG) carries sex steroids in blood regulating their bioavailability. Red wine consumption increases plasma SHBG levels, and we have discovered that resveratrol, a polyphenol enriched in red wine, acts specifically through the human constitutive androstane receptor (CAR), a drug/xenobiotic detoxification gene regulator, to increase hepatic SHBG production. Chromatin immunoprecipitation and luciferase reporter gene assays show that human CAR binds ...

Low plasmasex hormone-binding globulin (SHBG) levels are present in fatty liver disease, which represents a spectrum of diseases ranging from hepatocellular steatosis through steatohepatitis to fibrosis and irreversible cirrhosis. We are interested in studying the molecular mechanisms by which plasma SHBG levels are reduced in fatty liver disease. In this regard, we have previously shown that fat accumulation in the liver reduces SHBG production by reducing hepatic nuclear fac...

Low plasma sex hormone-binding globulin (SHBG) levels are present in fatty liver disease, which represent a spectrum of diseases ranging from hepatocellular steatosis through steatohepatitis to fibrosis and irreversible cirrhosis. We have previously determined that fat accumulation reduces SHBG production in different non-alcoholic fatty liver disease (NAFLD) mouse models and that SHBG plays an active role in the development of this disease. In the present work, we are interes...
