The results indicate an antiproteinuric and antifibrotic nephroprotective effect of ramipril in COL4A3 -/- mice is mediated by down-regulation of TGF-beta1. This effect in mice is enhanced by initiation of therapy during pre-symptomatic disease. The data in COL4A3 -/- mice as an animal-model for Alport syndrome suggest that ramipril might as well delay renal failure in humans with AS. Early diagnosis and preemptive treatment also may be crucial in humans.
The results indicate an antifibrotic, nephroprotective effect of ACE inhibitors and AT1 antagonists in an animal model of progressive renal fibrosis. The greater antifibrotic effect of ramipril at the maximal therapeutic doses employed may not be explained by different antiproteinuric or blood pressure lowering properties, but by-in contrast to candesartan-its ability to hinder the proinflammatory, profibrotic activation of the angiotensin receptor 2.
Cerivastatin prolongs the lifespan of COL4A3 knockout mice, reduces proteinuria and delays uraemia. These effects are associated with decreased renal fibrosis and a reduction of inflammatory cell infiltration.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
