Corin: an ANP protease that may regulate sodium reabsorption in nephrotic syndrome

Abstract:
The serine/threonine protease corin, which proteolytically activates atrial natriuretic peptide (ANP), is reduced in the kidneys of animals with nephrotic syndrome and glomerular nephritis. Polzin et al. provide evidence for a linkage between the decreased corin and β-epithelial sodium channel, phosphodiesterase 5, and cGMP-dependent protein kinase II in the nephrotic kidney. They propose that decreases in cGMP resulting from the reduced corin may be responsible for the Na(+) retention and volume expansion that are hallmarks of these kidney diseases.

Glomerulus: Structure and Function
The glomerulus is a tiny, intricate network of capillaries located at the beginning of the nephron. It's enveloped by the Bowman's capsule and receives its blood supply from an afferent arteriole, which divides into numerous capillaries...
Renal Regulation of Acid-Base Balance
In the kidneys, cells within the proximal convoluted tubules (PCT) and the collecting ducts secrete hydrogen ions (H+) into the tubular fluid. Specifically, in the PCT, Na+/H+ antiporters secrete H+ while reabsorbing Na+.
