Renal Effects

I've got it right here in my textbook (Medical Physiology, Boron and Boulpaep 2005) that the net renal effect of ATII is to DECREASE glomerular filtration rate, not increase it as the article currently states. --AaronM (talk) 16:48, 19 March 2008 (UTC)

ATII constricts the efferent arteriole *increasing* the GFR. The action of an ACE inhibitor will decrease GFR (but will maintain perfusion of the vasa recta and other tissues) Falconerd (talk) 05:29, 27 September 2012 (UTC)

More correctly, low(er) levels of ATII preferentially constrict the efferent arteriole, increasing the GFR. At high enough levels of ATII, total resistance will be so high that total GFR will actually decrease.130.132.173.48 (talk) 04:33, 3 November 2014 (UTC)

As I understand things, Angiotensin has been factored out to seven levels recently. A1-A7.

"Broken" reference

Reference #3 - ^ Physiology at MCG 7/7ch09/7ch09p16 - leads me to a 403 error:

How to mention drug formulations and approvals

Eg Giapreza redirects here but it is not mentioned. It is an IV angiotensin II - could mention brand names under each type - or perhaps in a separate section Proprietary formulations or As medical therapy ? - Rod57 (talk) 12:44, 4 March 2018 (UTC)

There don't seem to be a lot of different formulations or brands of angiotensin II and the other forms (angiotensin I, III, and IV) do not seem to have been used as drugs. As each form of angiotensin is a distinct molecular entity, if Giapreza were mentioned in this article, it should be under the angiotensin II section. However because of conflicts between WP:MCBMOS and WP:MEDMOS, I think it would be better to split out angiotensin II (medication) as a separate article. Boghog (talk) 17:26, 4 March 2018 (UTC)

I took the liberty of creating angiotensin II (medication). I hope this is OK. Boghog (talk) 20:40, 4 March 2018 (UTC)

Adding Angiotensinogen Information

Hi all, I'm working on this page for a school project. I have some edits on the angiotensinogen portion that I'm planning to update. They're included below in case someone has comments before I go making changes.

Angiotensinogen is synthesized in the liver[1] and is a precursor for angiotensin, but has also been indicated as having many other roles not related to angiotensin peptides.[2] It is a member of the serin family of proteins, leading to another name: Serin A8[3]. In addition, a generalized crystal structure can be estimated by examining other proteins of the serin family, but angiotensinogen has an elongated N-terminus compared to other serin family proteins.[4] Angiotensinogen is cleaved at the N-terminus by renin to result in angiotensin I, which will later be modified to become angiotensin II.[2][4] This peptide is 485 amino acids long, and 10 N-terminus amino acids are cleaved when renin acts on it.[2]

Error in PDB codes

The list of PDB codes for AGT's infobox (currently) looks like this: 2WXW, 2X0B, 4APH,%%s1N9U, 1N9V,%%s1N9V, 1N9U, 3CK0, 4AA1, 4APH, 5E2Q. Note the %%s leading two of the codes. I checked the source at http://www.rcsb.org/pdb/results/results.do?tabtoshow=Current&qrid=834DF9F1, and found it wasn't the source of extraneous symbols. So it might be in the infobox, but more likely it's something in wikidata. The wikidata entry for AGT is very large, and a quick search didn't reveal where PDB codes are drawn from. I'm hoping someone more familiar with the subject content will know what's up with the PDB codes. Prime Lemur (talk) 23:05, 5 May 2020 (UTC)
