These data reveal that endogenous androgens (TES) exert anti-hypertensive effects that appear to involve non-genomic and possibly genomic mechanism(s), resulting in reductions in RAS expression in the kidney and enhanced systemic vasodilation. (biomedcentral.com)
Using knockout mice lack of receptors essential to the proximal tubule endocytic uptake of proteins from the glomerular ultrafiltrate, the mechanism of renal uptake of 99m Tc-DMSA is recently suggested as receptor-mediated endocytosis [ 6 ]. (chikd.org)
