The effects of 2-deoxy-D-glucose on brown adipose tissue of lean and obese Zucker rats. 1986

J Allars, and D A York

The response of brown adipose tissue (BAT) thermogenesis, as measured by mitochondrial GDP binding, of lean and obese Zucker fa/fa rats to 2-deoxy-D-glucose (2-DOG) has been investigated. 2-DOG reduced BAT mitochondrial GDP binding of lean rats but had no effect in obese rats. Adrenalectomy increased BAT GDP binding in obese rats and restored the 2-DOG inhibitory effect. Corticosterone inhibited GDP binding in lean rats and abolished the 2-DOG inhibitory effect. 2-DOG induced hyperphagia and hyperglycaemia in lean rats, but these effects were either absent or attenuated in the obese. The possibility that a glucocorticoid inhibition of glucose metabolism impairs sympathetic activity in the obese rats is discussed.

UI	MeSH Term	Description	Entries
D006963	Hyperphagia	Ingestion of a greater than optimal quantity of food.	Overeating,Polyphagia,Polyphagias
D008297	Male		Males
D009765	Obesity	A status with BODY WEIGHT that is grossly above the recommended standards, usually due to accumulation of excess FATS in the body. The standards may vary with age, sex, genetic or cultural background. In the BODY MASS INDEX, a BMI greater than 30.0 kg/m2 is considered obese, and a BMI greater than 40.0 kg/m2 is considered morbidly obese (MORBID OBESITY).
D011924	Rats, Zucker	Two populations of Zucker rats have been cited in research--the "fatty" or obese and the lean. The "fatty" rat (Rattus norvegicus) appeared as a spontaneous mutant. The obese condition appears to be due to a single recessive gene.	Zucker Rat,Zucker Rats,Rat, Zucker
D001786	Blood Glucose	Glucose in blood.	Blood Sugar,Glucose, Blood,Sugar, Blood
D001833	Body Temperature Regulation	The processes of heating and cooling that an organism uses to control its temperature.

D002001	Adipose Tissue, Brown	A thermogenic form of adipose tissue composed of BROWN ADIPOCYTES. It is found in newborns of many species including humans, and in hibernating mammals. Brown fat is richly vascularized, innervated, and densely packed with MITOCHONDRIA which can generate heat directly from the stored lipids.
