Heme Peroxidase-Catalyzed Iodination of Human Angiotensins and the Effect of Iodination on Angiotensin Converting Enzyme Activity

open access: yes, 2016
The heme peroxidase-catalyzed iodination of human angiotensins I and II is described. It is observed that lactoperoxidase (LPO) can effectively and selectively iodinate the tyrosyl residues in angiotensin peptides.

A Generative Neuro‐Symbolic AI for Protein Sequence Design

open access: yesAdvanced Science, EarlyView.
We introduce EffieDes, a neuro‐symbolic framework coupling deep learning‐based fitness landscape parameterization with exact automated reasoning. Unlike greedy sampling, EffieDes identifies sequences that globally optimize fitness while satisfying intricate design constraints.

Angiotensin I-converting enzyme-like activity in tissues from the Atlantic hagfish (Myxine glutinosa) and detection of immunoreactive plasma angiotensins

open access: yes, 2004
Using a highly sensitive fluorimetric assay, significant levels of angiotensin I -converting enzyme-like activity (ACELA) were detected in a range of tissues (branchial heart, gill, kidney with associated vasculature and archinephric duct, liver, whole ...

SPARC Drives Podocyte Mitochondrial Damage and Ferroptosis in Diabetic Kidney Disease Following Klotho Deficiency

open access: yesAdvanced Science, EarlyView.
Klotho deficiency promotes podocyte mitochondrial dysfunction and ferroptosis through activation of the PKCα/CUX1/SPARC/TGFβ‐RII axis. SPARC emerges as a key mediator linking Klotho loss to podocyte injury in DKD and other kidney injury models, suggesting broader implications for CKD progression.

Protein translocation into dendrites: implication of glia-derived angiotensins in noradrenergic brainstem neurons.

open access: yes, 2006
Noradrenaline (NA) released by dendrites of locus coeruleus (LC) neurons controls LC neuron activity, and hence, NA released from noradrenergic fibers in terminal fields. NA synthesis is dependent on tyrosine hydroxylase (TH), whose dendritic presence is

Proteolytic processing of angiotensin-I in human blood plasma. [PDF]

open access: yesPLoS ONE, 2013
In mammalian species, except humans, N-terminal processing of the precursor peptide angiotensin I (ANG-1-10) into ANG-2-10 or ANG-3-10 was reported. Here we hypothesize that aminopeptidase-generated angiotensins bearing the same C-terminus as ANG-1-10 ...

An Engineered HR1‐Stem Helix‐HR2 Trimeric Platform for Developing Broad‐Spectrum Coronavirus Vaccines

open access: yesAdvanced Science, EarlyView.
Sun et al. report a self‐assembling trimeric subunit vaccine platform termed RHS, which integrates the JN.1 receptor‐binding domain (RBD) with the heptad repeat 1 (HR1), stem helix (SH), and heptad repeat 2 (HR2) regions. The SARS‐CoV‐2 RHS vaccine elicits variant‐reactive RBD‐specific antibodies and cross‐reactive SH‐specific antibodies against ...

Long-term habituation (LTH) in the crab Chasmagnathus: a model for behavioral and mechanistic studies of memory

open access: yesBrazilian Journal of Medical and Biological Research, 1997
A decade of studies on long-term habituation (LTH) in the crab Chasmagnathus is reviewed. Upon sudden presentation of a passing object overhead, the crab reacts with an escape response that habituates promptly and for at least five days. LTH proved to be

Site of Action of Angiotensin and other Vasoconstrictors on the Kidney

open access: yes, 1971
Angiotensin II, angiotensin I, adrenaline, or noradrenaline was infused in rabbit kidneys isolated and perfused with oxygenated Krebs solution. Adrenaline increased the perfusion pressure and slightly decreased the filtration fraction and the glomerular
