Treatment with A71915 led to a significant reduction in renal cGMP content material in 4-copy mice (60.8 2.8 pmole/mg protein; P .05), though Rp remedy created only a modest change in renal cGMP content in 4-copy mice (Table 1). Similarly, we located a substantial reduction in plasma cGMP levels in 0-copy mice (2.five 0.four pmole/mL; P .001), a proportionate significant raise (two-fold) in plasma cGMP concentration occurred in untreated 4-copy mice (40.9 2.5 pmole/mL; P .001) as compared to 2-copy mice (19.1 1.1 pmole/mL). Plasma cGMP content was considerably reduced in 2-copy mice after remedy with each A71915 (7.4 0.7 pmole/mL; P .001) and Rp (14.9 1.five pmole/mL; P .05).The protein levels of cGK I and cGK II inside the kidneys of all of the experimental animals have been determined by Western blot analysis (Figure 1B). Densitometric evaluation showed that cGK1 expression was reduced by 90 and cGK II expression by virtually 66 in the kidneys of 0-copy mice as compared to 2-copy wild-type mice provided exactly the same remedies (Figure 1C,D). Gene-duplication of Npr1 (4-copy) mice showed a considerable boost in renal expression of cGK I (1.7-fold; P .01) and cGK II (two-fold; P .001). There was a considerable reduction in expression of cGK I (80) and cGK II (67) in 2-copy mice immediately after A71915 therapy (Figure 1C,D). Similarly, just after A71915 treatment for 15 days, 4-copy mice also showed significant compromises with renal cGK I (46) and cGK II (65) expression. Rp therapy led to reductions of only 20 in cGK I and 30 in cGK II expression inside the kidneys of 4-copy mice compared with untreated handle mice.3.three Renal cGK activity and cGK expressionThe final results of renal cGK activity assays are shown in Figure 1. The endogenous cGK activity in kidney tissues was downregulated in 0-copy mice by 60 (P .001), in 2-copy + A71915 mice by 53 (P .01), and in 2-copy + Rp mice by 39 (P .05) as when compared with untreated 2-copy manage mice. The endogenous cGK activity of gene-duplicated 4-copy mice was improved by two.8-fold as compare.
