Regulation of lipoprotein lipase synthesis and 3T3-L1 adipocyte metabolism by recombinant interleukin 1.

When fully differentiated 3T3-L1 adipocytes were exposed to purified, recombinant murine interleukin 1 (rIL-1), a dose-dependent suppression of lipoprotein lipase activity was observed. The loss of activity reached a maximum of 60-70% of control and appeared to be due to an effect on the synthesis of the enzyme as judged by a suppression of the ability to incorporate [35S]methionine into immunoprecipitable lipoprotein lipase. There was no general effect on protein synthesis as determined by radiolabel incorporation into acid precipitable protein; however, after a 17 h exposure of the 3T3-L1 cells to recombinant interleukin 1, the synthesis of two proteins (molecular weights, 19,400 and 165,000 daltons) was enhanced several-fold. When the effect of Il-1 on the major metabolic pathways of the adipocyte was investigated, lipolysis as measured by glycerol release from the cells was markedly enhanced after a 17 h incubation with the hormone, while no effect was observed on de novo fatty acid synthesis. These effects on the metabolism of the adipocytes occur at concentration on a basis of molecules per cell, similar (only a 3-fold difference) to those required for stimulation of [3H]thymidine incorporation into mouse thymocyte DNA, suggesting that IL-1 may be a physiologically significant effector of adipocyte metabolism.[1]
