The NADPH Oxidase Isoform 1 Contributes to Angiotensin II-Mediated DNA Damage in the Kidney
In higher concentrations, the blood pressure regulating hormone angiotensin II leads to vasoconstriction, hypertension, and oxidative stress by activating NADPH oxidases which are a major enzymatic source of reactive oxygen species (ROS).

In silico Prediction of Mozenavir as potential drug for SARS-CoV-2 infection via Binding Multiple Drug Targets [PDF]
Since the epidemic began in November 2019, no viable medicine against SARS-CoV-2 has been discovered. The typical medication discovery strategy requires several years of rigorous research and development as well as a significant financial commitment, which is not feasible in the face of the current epidemic.

Modification of tumour blood flow using the hypertensive agent, angiotensin II [PDF]
The effects of different doses of angiotensin II (0.02 to 0.5 microgram kg-1 min-1 on mean arterial blood pressure, tissue blood flow and tissue vascular resistance were investigated in BD9 rats.

A new amphipathic molecule, S416 is discovered, that locks the SARS‐CoV‐2 spike protein in its closed state, blocking viral entry. S416 acts as a molecular bolt, binding six sites: three between adjacent RBDs and three connecting NTDs to RBDs. This dual‐locking mechanism stiffens the spike structure and reduces its flexibility.

Analysis of the Vasorelaxant Action of Angiotensin II in the Isolated Rat Renal Artery
Taking into consideration that mechanisms involved in the vasodilatator actions of angiotensin II have not yet been completely elucidated, the present study was undertaken in order to examine the mechanisms underlying the angiotensin II–induced ...

Statin treatment in hypercholesterolemic men does not attenuate angiotensin II-induced venoconstriction. [PDF]
Experimental studies suggested that statins attenuate vascular AT1 receptor responsiveness. Moreover, the augmented excessive pressor response to systemic angiotensin II infusions in hypercholesterolemic patients was normalized with statin treatment.

Featuring ACE2 binding SARS-CoV and SARS-CoV-2 through a conserved evolutionary pattern of amino acid residues [PDF]
Spike (S) glycoproteins mediate the coronavirus entry into the host cell. The S1 subunit of S-proteins contains the receptor-binding domain (RBD) that is able to recognize different host receptors, highlighting its remarkable capacity to adapt to their hosts along the viral evolution.

Calpain‐2‐Mediated Endothelial Focal Adhesion Disruption in Thoracic Aortic Dissection
The elevated expression of Capn2 in endothelial cells activates focal adhesion signaling by cleaving Talin1 and assembling Itgav, which compromises the integrity of the endothelial barrier and induces vascular inflammation. Inhibition of calpain through both pharmacological and transgenic approaches has effectively suppressed the onset and progression ...

Effect of Angiotensin II on Blood Flow in Acute and Chronically Inflamed Knee Joints of Rabbits: The Role of Nitric Oxide [PDF]
Background: Angiotensin converting enzyme (ACE) upregulationin stromal cells of joints affected by rheumatoid arthritismay lead to higher tissue angiotensin II that is a vasoconstrictorand mitogen factor.

Mapping active allosteric loci SARS-CoV Spike Proteins by means of Protein Contact Networks [PDF]
Coronaviruses are a class of virus responsible of the recent outbreak of Human Severe Acute Respiratory Syndrome. The molecular machinery behind the viral entry and thus infectivity is based on the formation of the complex of virus spike protein with the angiotensin-converting enzyme 2 (ACE2).
