This study was designed to assess the effects of long-term adaptation to a high protein diet on energy intake, body weight gain, body composition and splanchnic metabolic indicators in rats. For this purpose, adult male Wistar rats were fed either a 50 g/100 g dry matter (DM) protein diet (P50 group) or a 14 g/100 g DM protein diet (P14 group) for 21 d.(More)
Acute hyperinsulinemia in rats have been shown to cause enhanced endocytosis of liver insulin receptors with little or no change in the total receptor number. To determine whether a similar phenomenon occurs in long-lasting hyperinsulinemia, the subcellular distribution of liver insulin receptors has been studied in rats infused continuously with insulin(More)
Acute insulin treatment in rats has recently been shown to cause a rapid increase in liver low-Km cAMP phosphodiesterase (PDE) activity, which selectively affects Golgi fractions. To assess the physiological significance of this observation, the cAMP PDE activity associated with liver Golgi fractions has been measured in genetically obese Zucker rats, which(More)
