From: Angiostatin production increases in response to decreased nitric oxide in aging rat kidney
Angiostatin production in aging rat kidney. (a) Western blot analysis for angiostatin, cathepsin D (CTPD), and matrix metalloproteinase 9 (MMP-9). n=6 for each group. Data are expressed as mean±s.e.m. *P<0.05 versus 4 months of age (4 months). Glyceraldehyde-3-phosphate dehydrogenase (GAPDH). (b) Cathepsin activity as determined by enzyme-linked immunosorbent assay. n=6–8 for each group. Data are expressed as mean±s.e.m. *P<0.05 versus 4 months. (c) MMP-9 activity as determined by zymography. n=6 for each group. Data are expressed as mean±s.e.m. *P<0.05 versus 4 months.
