Study TitleTCA Cycle Metabolites of Dietary Salt Effects on Blood Pressure in Rat Urine and Kidney Tissue (part X)
Study SummaryWe propose to analyze kidney tissue extract and urine samples from SS and SS.Fh1+ transgenic rats in addition to the analysis of urine samples from the DASH2 trial. The analysis of the rat samples will be highly valuable for several reasons. First, it will to take the findings in human subjects back to animal models and prepare us for further mechanistic studies. We hypothesize at least some of the effects of dietary salt intake on metabolite profiles in human will be recapitulated or altered in the SS rat. If this is confirmed, we will have a highly informative animal model ready for mechanistic studies in which we can investigate the functional contribution of specific metabolites to hypertension and the mechanisms involved. Second, the rat study will allow us to take advantage of a new and unique transgenic SS.Fh1+ model that we recently developed that overexpresses fumarase (Fh1) on the genetic background of the SS rat. Fumarase is a TCA cycle enzyme previously implicated in salt-induced hypertension in SS rats.
