We evaluated the influence of a diet supplemented with olive oil (20% by weight) (OO) on the activity of glutamyl aminopeptidase (GluAP) and aspartyl aminopeptidase (AspAP), which are involved in angiotensin metabolism. Serum concentrations of total cholesterol and fatty acids were also measured. Animals fed on the OO diet gained significantly more weight than did controls from the second week until the end of the feeding period. Serum total cholesterol concentration was significantly higher in the OO group than in control mice. Total monounsaturated fatty acids increased in OO-fed animals, but total saturated fatty acids decreased. No differences between the two groups were observed for total polyunsaturated fatty acids. Serum from animals fed on the OO diet contained significantly lower proportions of myristic, pentadecanoic, palmitic, palmitoleic, vaccenic, alpha-linolenic, gamma-linolenic, and 11,14-eicosadienoic acids than did serum from control animals. In contrast, the OO group had higher levels of oleic, stearic, and gondoic acids. GluAP activity decreased significantly in the serum of OO-fed animals. In these animals soluble AspAP activity was significantly higher in the testis, and significantly lower in the lung and adrenal, in comparison to controls. Membrane-bound AspAP activity was higher in the testis and atrium, and lower in lung, in the OO group. Soluble GluAP activity was significantly lower in the testis of OO-fed animals. Membrane-bound GluAP activity did not differ between the two groups in any of the tissues analyzed. Serum AspAP and GluAP activities correlated negatively with palmitoleic and vaccenic acid respectively in the OO group. However, no significant correlations were found in the control group. These results may reflect functional changes in the renin-angiotensin system in the serum, adrenal, testis, lung and atrium after feeding with a diet enriched in olive oil.
