Chronic ethanol feeding causes accumulation of serum cholesterol in rat pancreas. 1984

J S Wilson, and J B Somer, and R C Pirola

In a previous study, a rat model of ethanol-induced pancreatic steatosis was developed in which chronic ethanol feeding resulted in a twofold increase in pancreatic cholesteryl ester content. The studies reported here were performed in order to elucidate the mechanism of this cholesteryl ester accumulation. Rats were pair fed ethanol or control diets for 3 weeks. Ethanol feeding resulted in an increased accumulation of serum cholesterol in the pancreas. Ethanol feeding also resulted in increased in vitro incorporation of labeled acetate and mevalonate into the sterol moiety of pancreatic cholesteryl ester and increased incorporation of labeled acetate into its fatty acid component. These results suggest that chronic ethanol feeding causes pancreatic cholesteryl ester accumulation by affecting exchange of cholesterol between serum and pancreatic tissue.

UI	MeSH Term	Description	Entries
D008798	Mevalonic Acid	A dihydroxy monocarboxylic acid and precursor in the biosynthetic pathway known as the mevalonate pathway, which produces terpenes and steroids that are vital for diverse cellular functions.	Mevalonate,Acid, Mevalonic
D009929	Organ Size	The measurement of an organ in volume, mass, or heaviness.	Organ Volume,Organ Weight,Size, Organ,Weight, Organ
D010179	Pancreas	A nodular organ in the ABDOMEN that contains a mixture of ENDOCRINE GLANDS and EXOCRINE GLANDS. The small endocrine portion consists of the ISLETS OF LANGERHANS secreting a number of hormones into the blood stream. The large exocrine portion (EXOCRINE PANCREAS) is a compound acinar gland that secretes several digestive enzymes into the pancreatic ductal system that empties into the DUODENUM.
