Chronic activation of the renin angiotensin system (RAS) favors several cardiac diseases, among which myocardial hypertrophy occupies an outstanding place. In this context, the hyperactivity of the cardiac Na+ /H+ (NHE-1) exchanger plays a key role. The pathologic remodeling of the myocardium constitutes an independent risk factor for morbidity and mortality with continuously increasing healthcare cost. Therefore, the development of better therapeutic strategies emerges as highly mandatory. Our goal was to prevent angiotensin II (ANGII)-induced cardiac hypertrophy by NHE-1 gene silencing in Wistar rats...

Human immunodeficiency virus associated nephropathy (HIVAN) is a unique form of a renal parenchymal disorder. This disease and its characteristics can be accredited to incorporation of DNA and mRNA of human immunodeficiency virus type 1 into the renal parenchymal cells. A proper understanding of the intricacies of HIVAN and the underlying mechanisms associated with renal function and disorders is vital for the potential development of a reliable treatment for HIVAN. Specifically, the renal tubule segment of the kidney is characterized by its transport capabilities and its ability to reabsorb water and salts into the blood...
