- Abstract: Objetivo: To study some metabolic and cardiovascular phenotypes in diabetic genetically modified mice for the ACE gene. Métodos e Resultados: Three groups of male (C57BL/6J) mice with the following genotypes, wild (+/+), heterozygous (+/-), and insertional (+/++) for the ACE gene, were studied. Three-week-old mice were randomized into control (nondiabetic -ND) or diabetic groups (D). They were either fed with an atherogenic (AD) or a control diet (CD). At 7 weeks of age, streptozotocin (STZ-125mg/kg body weight-ip) was injected. Weekly tail-cuff blood pressure (BP), blood glucose (BG), body weight (BW), and chow consumption were measured from 7 (before diabetes) until 20 weeks of age when blood samples were collected for BG determination and the heart, aorta and kidneys were removed for hystological analysisResults: No differences were observed in BP and heart rate among all groups. D -+/++ mice had a higher mortality rate than +/+ and +/- mice. In ND+ CD animals, BG was higher in +/+ then in +/- mice. BG was higher in ND + AD mice with all genotypes. The +/- mice had the highest BG and the lowest BW among diabetics, fed with CD or AD. BW decrease was more critical in the +/- group fed with CD. In the ND mice, BW was not influenced by the diet. Diabetic animals fed with AD had a higher BG than in the group treated with CD. Conclusões: It was shown that this model is adequate for the study of diabetes pathophysiology. In this context, the extreme loss of BW inthe diabetics fed with CD is a metabolic characteristic of diabetic patients. Interestingly, it was also shown that despite of the highest BG and BW loss, +/- animals had the lowest mortality. This indicates that beside the metabolic environment, ACE genetic background is an important factor associated with mortality
