The physiological and biochemical mechanisms by which the intact animal regulates its metabolism of lipids and the role of the liver in the control of blood lipids has long been a topic of interest in this laboratory. Our approach to the problem has been the examination of the uptake, metabolism, and release of the serum lipids and lipoproteins by the isolated, perfused rat liver. Our attention has been focused for some time on the various factors regulating the output and accumulation of triglyceride by the liver. It is now evident that a variety of hormones influence the hepatic metabolism of triglycerides. On the following pages is a brief discussion of some of the recent work from this laboratory on lipid metabolism in insulin deficiency (induced by alloxan diabetes), (2) on the effects of glucagon and insulin on hepatic triglyceride metabolism, and (3) on the modulating effects of substrate concentration (free fatty acids) on these processes. In order to present a coherent picture of the current status of the work, it will be useful to recount some of the earlier findings.
