Effect of renin inhibitor ES-1005 or captopril on the renin synthesis by the kidney was investigated in sodium-depleted marmosets. The level of kidney renin mRNA was measured after 2-hour (acute study) and one-week (chronic study) administrations of the two agents. Relative amounts of kidney renin mRNA were measured by densitometric Northern blot analysis using an alpha-32P-labelled human renin cDNA fragment as a hybridization probe. In the acute study, treatment with captopril significantly increased plasma renin activity (PRA) (p less than 0.05), but did not change the level of kidney renin mRNA. In the chronic study, treatment with captopril markedly increased PRA as well as the level of kidney renin mRNA (4.7-fold and 6.3-fold increases, respectively). In contrast, treatment with ES-1005 completely inhibited PRA and significantly suppressed the level of kidney renin mRNA in both acute and chronic studies (about one-third of the normal control, p less than 0.05). These results suggest that renin inhibitor ES-1005 not only inhibits plasma renin activity but also suppresses the synthesis of renin by the kidney.

D012083 Renin A highly specific (Leu-Leu) endopeptidase that generates ANGIOTENSIN I from its precursor ANGIOTENSINOGEN, leading to a cascade of reactions which elevate BLOOD PRESSURE and increase sodium retention by the kidney in the RENIN-ANGIOTENSIN SYSTEM. The enzyme was formerly listed as EC 3.4.99.19.

D002216 Captopril A potent and specific inhibitor of PEPTIDYL-DIPEPTIDASE A. It blocks the conversion of ANGIOTENSIN I to ANGIOTENSIN II, a vasoconstrictor and important regulator of arterial blood pressure. Captopril acts to suppress the RENIN-ANGIOTENSIN SYSTEM and inhibits pressure responses to exogenous angiotensin.

D012333 RNA, Messenger RNA sequences that serve as templates for protein synthesis. Bacterial mRNAs are generally primary transcripts in that they do not require post-transcriptional processing. Eukaryotic mRNA is synthesized in the nucleus and must be exported to the cytoplasm for translation. Most eukaryotic mRNAs have a sequence of polyadenylic acid at the 3' end, referred to as the poly(A) tail. The function of this tail is not known for certain, but it may play a role in the export of mature mRNA from the nucleus as well as in helping stabilize some mRNA molecules by retarding their degradation in the cytoplasm.
