Hepatic Fatty Acid Profile of Rats Fed a Triheptanoin-based Ketogenic Diet.

چکیده
OBJECTIVE the aim of this study was to evaluate the influence of consumption of a ketogenic diet supplemented with triheptanoin, a medium-chain anaplerotic triacylglycerol, on the liver fatty acid profile of Wistar rats. METHODS three groups of male Wistar rats (n = 10) were submitted to an AIN-93 control diet, a triheptanoin- based ketogenic diet, or a soybean oil-based ketogenic diet for 60 days. Excised livers were subjected to lipid extraction and methylation to obtain fatty acids methyl esters, which were subjected to gas chromatography- mass spectrometry. RESULTS AND DISCUSSION compared to the rats fed the control diet, those fed ketogenic diets showed a significant reduction in the concentrations of 9-hexadecenoic and 9-octadecenoic acids, whereas those fed triheptanoin showed increased levels of octadecanoic acid. CONCLUSION changes in the liver fatty acid profiles of the rats fed a triheptanoin-based or a soybean oil-based ketogenic diet did not seem to be related to the dietary fat source, but rather to the characteristics of the ketogenic diets themselves.

The anaplerotic odd-medium-chain triglyceride triheptanoin is used in clinical trials for the chronic dietary treatment of patients with long-chain fatty acid oxidation disorders. We previously showed (Kinman RP, Kasumov T, Jobbins KA, Thomas KR, Adams JE, Brunengraber LN, Kutz G, Brewer WU, Roe CR, Brunengraber H.

متن کاملDietary intake of ain-93 standard diet induces Fatty liver with altered hepatic fatty acid profile in Wistar rats.
BACKGROUND There are several standard diets for animals used in scientific research, usually conceived by scientific institutions. The AIN-93 diet is widely used, but there are some reports of fatty liver in Wistar rats fed this diet. OBJECTIVE We aimed to evaluate the hepatic repercussions of the AIN-93 diet intake in Wistar rats. METHODS Forty newly-weaned 21-day-old male Wistar rats were...
متن کاملHormonal control of ketogenesis. Rapid activation of hepatic ketogenic capacity in fed rats by anti-insulin serum and glucagon.
The enhanced capacity for long-chain fatty acid oxidation and ketogenesis that develops in the rat liver between 6 and 9 h after the onset of starvation was shown to be inducible much more rapidly by administration of anti-insulin serum or glucagon to fed rats. After only 1 h of treatment with either agent, the liver had clearly switched from a "nonketogenic" to a "ketogenic" profile, as determ...

Backgrounds: Type 2 diabetes mellitus is the most common metabolic disease and free fatty acids, as signaling molecules, can play a crucial role in the development of it. Different free fatty acids, through various cell membrane receptors, induce different effects on metabolic pathways and thereby affect insulin sensitivity. Simvastatin is a cholesterol decreasing drug prescrib...
