Aqueous extracts of acetone/ether powders of surgically obtained specimens of human tumors hydrolyzed 3H-labeled triolein in a dose-dependent manner. The lipolytic activity in these extracts was inhibited by anti-lipoprotein lipase (LPL) IgG dose-dependently, 25 micrograms of anti-LPL IgG causing
A large amount of triacylglycerol lipase activity was present in the circulating blood of normal mice, and this activity decreased with development of Sarcoma 180 inoculated intraperitoneally. Triacylglycerol lipase in plasma of both normal and tumor-bearing mice was retained on the
