Lipogenesis as related to endocrine control of adipose cellularity in the rat.
The incorporation rate of 3H from 3H2O in the total lipids of rat retroperitoneal adipose tissue (RPAT) according to age was followed in slightly hyperthyroid rats, in type-2 diabetic rats and in control rats. Until 12 weeks of age, the RPAT of the hyperthyroid animals exhibited hyperplasia and an increase in lipogenesis per g of wet weight or per whole fat pad. Fat cel number and lipogenesis per g of wet weight or per whole fat pad were reduced in adult diabetic rats. The concomitant changes in fat cell number and lipid synthesis in the RPAT of the two groups of treated rats have been discussed.
