Spinal Nitric Oxide Synthase Type II Increases Neurosteroid-metabolizing Cytochrome P450c17 Expression in a Rodent Model of Neuropathic Pain. [PDF]

Exp Neurobiol, 2019
We have previously demonstrated that the neurosteroid dehydroepiandrosterone sulfate (DHEAS) induces functional potentiation of N-methyl-D-aspartate (NMDA) receptors via increases in phosphorylation of NMDA receptor GluN1 subunit (pGluN1). However, the modulatory mechanisms responsible for the expression of the DHEA-synthesizing enzyme, cytochrome ...

ALDH2 rs671 Variant Lowers Blood Pressure Via the Endothelial HSPA5–PIEZO1–eNOS Pathway [PDF]

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease
Background The inactivating ALDH2 rs671 polymorphism, present in ≈8% of the global population and up to 30% to 50% of East Asian individuals, has been negatively associated with hypertension.

Differential contribution of T‐type voltage‐gated calcium channels to vascular reactivity in the aorta and renal artery of healthy rabbits [PDF]

Experimental Physiology
T‐type voltage‐gated calcium channels (VGCCs) are comparatively understudied in large conduit artery function relative to the well‐characterized L‐type channel subtype.

Inhibition of nitric oxide production of activated mice peritoneal macrophages is independent of the Toxoplasma gondii strain [PDF]

Memorias do Instituto Oswaldo Cruz, 2021
BACKGROUND Toxoplasma gondii causes toxoplasmosis and is controlled by activated macrophages. However, infection of macrophages by tachyzoites induces TGF-β signaling (TGF-s) inhibiting nitric oxide (NO) production.

Spironolactone treatment attenuates vascular dysfunction in type 2 diabetic mice by decreasing oxidative stress and restoring NO/GC signaling [PDF]

, 2015
Type 2 diabetes (DM2) increases the risk of cardiovascular disease. Aldosterone, which has pro-oxidative and pro-inflammatory effects in the cardiovascular system, is positively regulated in DM2.

Parkia speciosa Hassk. Empty Pod Extract Alleviates Angiotensin II-Induced Cardiomyocyte Hypertrophy in H9c2 Cells by Modulating the Ang II/ROS/NO Axis and MAPK Pathway

Frontiers in Pharmacology, 2021
Cardiac hypertrophy is characteristic of heart failure in patients who have experienced cardiac remodeling. Many medicinal plants, including Parkia speciosa Hassk., have documented cardioprotective effects against such pathologies.

NEURONAL (TYPE I) NITRIC OXIDE SYNTHASE REGULATES NUCLEAR FACTOR ϰ B ACTIVITY AND IMMUNOLOGIC (TYPE II) NITRIC OXIDE SYNTHASE EXPRESSION [PDF]

Japanese Journal of Pharmacology, 1997
Nitric oxide subserves diverse physiologic roles in the nervous system. NO is produced from at least three different NO synthase (NOS) isoforms: neuronal NOS (nNOS), endothelial NOS, and immunologic NOS (iNOS). We show that nNOS is the predominant isoform constitutively expressed in glia.

Activation of Endothelial Nitric Oxide Synthase by the Angiotensin II Type 1 Receptor [PDF]

Endocrinology, 2006
Enhanced angiotensin II (AngII) action has been implicated in endothelial dysfunction that is characterized as decreased nitric oxide availability. Although endothelial cells have been reported to express AngII type 1 (AT1) receptors, the exact role of AT1 in regulating endothelial NO synthase (eNOS) activity remains unclear.
