The aim of the present study was to test the hypothesis that elevation of prorenin in plasma is sufficient to induce cardiac fibrosis. Normotensive cyp1a1ren-2 transgenic rats with normal plasma prorenin and aldosterone levels were given 0.125% indole-3-carbinol (I3C) orally for a period of 12 wk. Plasma prorenin and aldosterone levels were determined in 4-wk intervals, and cardiac marker enzym...
Prorenin is expressed in certain extrarenal tissues, but normally only the kidneys process prorenin to renin and secrete renin into the circulation. Although transgenic animal lines containing the human renin (hREN) structural gene with either 0.9-kb or 3-kb 5'-flanking DNA express the transgene appropriately in renal juxtaglomerular cells and secrete hREN into the circulation, the source of th...
Human preprorenin was synthesized in Chinese hamster ovary (CHO) cells transfected with an expression vector containing renin cDNA sequences. These cells secrete an inactive form of renin (EC 3.4.23.15) that can be activated by trypsin. This inactive renin is precipitable by antibody generated against purified human renal renin and also by antisera generated to a synthetic peptide derived from ...
Recently, the binding of renin and prorenin to cellular receptors with the subsequent generation of second messengers and the production of physiological effects has been demonstrated. In addition, the internalization of prorenin by target cells has been associated with increased cellular synthesis of angiotensin and cardiac pathology. Also, a renin transcript lacking the sequences encoding a s...
To investigate whether mast cells release renin in the heart, we studied renin and prorenin synthesis by such cells, using the human mast cell lines human mastocytoma 1 and LAD2, as well as fresh mast cells from mastocytosis patients. We also quantified the contribution of mast cells to cardiac renin levels in control and infarcted rat hearts. Human mastocytoma 1 cells contained and released an...
The importance of the (pro)renin receptor (PRR) in the function of the central nervous system is increasingly evident because PRR seems to play a role in neuronal control of cardiovascular function. PRR expression is elevated in the nucleus of the solitary tract (NTS) of spontaneously hypertensive rats (SHR). In this study, we tested the hypothesis that altered activity of PRR in the NTS is lin...
