Characterization of phospho-(tyrosine)-mimetic calmodulin mutants.

open access: yesPLoS ONE, 2015
Calmodulin (CaM) phosphorylated at different serine/threonine and tyrosine residues is known to exert differential regulatory effects on a variety of CaM-binding enzymes as compared to non-phosphorylated CaM.

Glu298Asp endothelial nitric oxide synthase gene polymorphism interacts with environmental and dietary factors to influence endothelial function [PDF]

open access: yes, 2002
An endothelial nitric oxide synthase (eNOS) gene polymorphism (Glu298Asp) has been associated with cardiovascular disease. We investigated whether carriage of the polymorphism was associated with functional changes in the endothelium, and how genotype ...

A Hydrogen Sulfide–Releasing Dynamic Hydrogel Modulates Coordinated Neurovascular, Immune, and Angiogenic Responses for Scar‐Suppressed Diabetic Wound Repair

open access: yesAdvanced Science, EarlyView.
ROS‐Responsive H2S Hydrogel (HAPPF) Coordinated Regeneration for High‐Quality Diabetic Wound Repair.A self‐regulating dynamic hydrogel is developed to deliver a fluorogenic H2S donor in response to excessive ROS. Released H2S acts as a master regulator to resolve chronic inflammation (M2 polarization), restore VEGF‐driven angiogenesis, and rebalance ...

Salmonella typhimurium exploits macrophage-derived arginine as an intracellular signal for SPI-2 virulence gene activation

open access: yesFrontiers in Cellular and Infection Microbiology
BackgroundArginine contributes to host defense by serving as a substrate for inducible nitric oxide synthase (iNOS) to produce antimicrobial nitric oxide (NO). However, how bacterial pathogens respond to host arginine metabolism remains poorly understood.

Characterisation of type I and type II nNOS-expressing interneurons in the barrel cortex of mouse

open access: yesFrontiers in Neural Circuits, 2012
In the neocortex, neuronal Nitric Oxide-Synthase (nNOS) is essentially expressed in two sets of GABAergic neurons: type I neurons displaying a high expression and type II neurons displaying a weaker expression.

Tonic and phasic nitric oxide signals in hippocampal long-term potentiation [PDF]

open access: yes, 2006
Nitric oxide ( NO) participates in long-term potentiation (LTP) and other forms of synaptic plasticity in many different brain areas but where it comes from and how it acts remain controversial.

Nitric oxide formation during cortical spreading depression is critical for rapid subsequent recovery of ionic homeostasis [PDF]

open access: yes, 2003
NoCortical spreading depression (CSD) is a temporary disruption of local ionic homeostasis that propagates slowly across the cerebral cortex. Cortical spreading depression promotes lesion progression in experimental stroke, and may contribute to the ...

Metagenomic Association Uncovers Host Genotype‐Structured Rhizobacterial Networks and Novel Taxa That Enhance Soybean Salt Tolerance

open access: yesAdvanced Science, EarlyView.
An STI‐guided metagenomic association framework links soybean salt‐tolerance phenotypes with rhizosphere microbiome composition and network organization in natural saline soils. The approach identifies candidate beneficial taxa, including Thalassospira xiamenensis, and provides an efficient strategy for mining stress‐protective microbes from native ...

Targeting p21‐High Senescent Kupffer Cells Nanotherapeutically Potentiates Antitumor Immunity in Advanced Hepatocellular Carcinoma with Portal Vein Tumor Thrombus

open access: yesAdvanced Science, EarlyView.
Schematic illustration of a biomimetic SKEV@AAV platform targeting p21‐high senescent Kupffer cells (sKCs) in hepatocellular carcinoma (HCC) with portal vein tumor thrombus (PVTT). p21‐high sKCs accumulate in the PVTT microenvironment and establish an immunosuppressive, SASP‐rich environment that facilitates tumor cell proliferation and immune evasion.

eNOS protects from atherosclerosis despite relevant superoxide production by the enzyme in apoE mice. [PDF]

open access: yes, 2012
All three nitric oxide synthase (NOS) isoforms are expressed in atherosclerotic plaques. NOS enzymes in general catalyse NO production. However, under conditions of substrate and cofactor deficiency, the enzyme directly catalyse superoxide formation ...
