However, rats with chronic progressive nephropathy showed augmented renal content of angiotensinogen protein (13.5 +/- 3.5 versus 2.2 +/- 0.4 pixels in control rats; P &lt; 0.05), enhanced expression of cathepsin D-a renin-like enzyme-in cortical collecting tubules (103.5 +/- 27.0 versus 66.2 +/- 3.6 cells/mm2 in controls; P &lt; 0.01), and increased expression of AT1 receptor in interstitium (54.7 +/- 7.8 versus 1.3 +/- 0.4 cells/mm2 in controls; P &lt; 0.001).
