Chronic intraperitoneal or subcutaneous insulin administration increases triglyceride secretion rate (TGSR) in normal rats. We wished to determine the effect of this treatment on TGSR and the hepatic lipogenic enzymes acetyl-CoA carboxylase (ACC) and fatty acid synthase (FAS) in diabetic rats. Streptozotocin-diabetic rats, untreated (D), diabetic rats treated with insulin (3 U/day for 21 days) intraperitoneally (IP) or subcutaneously (SC) and non-diabetic rats (N) were studied. TGSR was determined using Triton WR-1339. Fasting glucose and triglyceride levels, high in D, were normalized by insulin treatment regardless of route. Peripheral insulin levels were lowest in D and highest in SC, portal insulin levels were lowest in D and highest in IP. Non-esterified fatty acid levels were not elevated in D, presumably due to adipose tissue depletion. TGSR was reduced in D (P<0.05) and was normalized following insulin administration, regardless of route. ACC activity was normal, but FAS was decreased in D (P<0.05). ACC and FAS were normal in both IP and SC. Thus, in streptozotocin-diabetic rats, chronic intraperitoneal or subcutaneous insulin treatment increases TGSR and FAS activity from their low levels in insulin-deficient rats to levels equal to but not higher than those in normal rats.
