| Abstract: | The aim of the study was to investigate the effects of adenosine 5'-monophosphate (AMP) in stroke-prone spontaneously hypertensive rats (SHRSP). Male rats (10 weeks old) were divided into three groups: a control group fed an AIN-93 M diet and two others fed supplemental AMP (17.5 and 87.5 mg/kg diet) for 3 weeks. AMP effectively improved hypertension, plasma triglyceride, and HDL-cholesterol, glucose, kidney function parameters, hepatic lipid, enhances plasma nitric oxide, and plasma adiponectin accompanied by the up-regulation of mRNA expression levels of the hepatic adiponectin receptor 2. Single and chronic oral administration of AMP affected the hepatic mRNA expression levels of genes involved in β-oxidation, fatty acid synthesis, and AMP-activated protein kinase. Furthermore, a single oral dose of AMP (40 mg/kg body weight) improved hypertension and hyperglycemia in SHRSP. In conclusion, AMP displays a novel effect in ameliorating metabolic-related diseases in SHRSP and could be beneficial as a functional food. |
