1. Alloxan-diabetic rats showed raised plasma triglyceride levels and low adipose tissue lipoprotein lipase activity compared with controls. Heart lipoprotein lipase activity appeared unaltered by the diabetic state. 2. Plasma post-heparin lipolytic activity was slightly but not significantly increased in the diabetic group. The significance of these findings is discussed.

Energy Dependent

Changes in adipose-tissue lipoprotein lipase activity that are independent of protein synthesis were investigated in an incubation system in vitro. Under appropriate conditions at 25 degrees C a progressive increase in the enzyme activity occurs that is energy-dependent. Part of the enzyme is rapidly inactivated when the tissue is incubated with adrenaline or adrenaline plus theophylline. The mechanism of this inactivation appears to be distinct from, and to follow, the activation of the enzyme. A hypothesis is presented to account for the results in terms of an activation of the enzyme during obligatory post-translational processing and a catecholamine-regulated inactivation of the enzyme as an alternative to secretion from the adipocyte.

The lipoprotein lipase activity per adipocyte was increased in the genetically obese rat (fa/fa). However, there was no difference between obese and lean animals when the enzyme activities were related to adipocyte surface area. The possible implications of the findings are discussed.
