Several lines of evidence indicate that fatty acid oxidation contributes to control of eating. We examined the effect of inhibitors of fatty acid oxidation (mercaptoacetate, R-3-amino-4-trimethylaminobutyric acid = emeriamine) on food intake in mice because fatty acid oxidation has been shown recently to increase the hepatic membrane potential in mouse liver, and this potential has been proposed to represent a signal for control of food intake. The effect of intraperitoneal injection of mercaptoacetate (200, 400, or 600 micromol/kg body weight) and emeriamine dihydrochloride (8.7, 17.4, 34.8, or 69.6 micromol/kg body weight) was investigated in mice fed a fat-enriched diet (18% fat). Both mercaptoacetate (400 or 600 micromol/kg) and emeriamine (34.8 or 69.6 micromol/kg) significantly increased food intake. These results suggest that fatty acid oxidation is also involved in feeding control in mice. Therefore, the pertinent mechanisms can be studied in mice.
