Development of Hypertension and Kidney Hypertrophy in Transgenic Mice Overexpressing ARAP1 Gene in the Kidney
Why the study?
Does proximal tubule-specific overexpression of ARAP1 cause hypertension in mice?
Population
Male transgenic mice overexpressing rat ARAP1 cDNA specifically in proximal tubules (lines 650 and 670)
Comparison
Proximal tubule-specific overexpression of ARAP1 vs Nontransgenic litter mates
Design
Preclinical
Follow-up
Up to 20 weeks of age
