A Review on the Clinical and Pathological Significance of Prorenin Receptor [(P)RR]
Abstract: The (pro)renin receptor (P)RR discovery, which is a novel constituent of Renin Angiotensin-Aldosteron System (RAS) has brought renin and (pro)renin back into spotlight. The (P)RR binds both renin and its inactive precursor (pro)renin, this binding triggers a cascade of intracellular signalling that eventually leads to upregulation of the expression of profibrotic genes, potentially leading to pathogenesis of cardiac and renal fibrosis, growth and remodelling. Clinically, it is also seen that …
