Nitric Oxide Signaling Pathway01:28

Nitric Oxide Signaling Pathway

5.9K
Nitric oxide (NO), an inorganic gas, acts as a potent second messenger in most animal and plant tissues. NO diffuses out of the cells that produce it and enters the neighboring cells to generate a downstream response. NO synthase (NOS) catalyzes NO production by the deamination of the amino acid arginine. There are three isoforms of NOS. Endothelial cells have endothelial NOS (eNOS), nerve and muscle cells have neuronal NOS (nNOS), and macrophages produce inducible NOS (iNOS) upon exposure...

Regulation of Angiogenesis and Blood Supply

3.1K
Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits.  Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl...

Regulation of the Unfolded Protein Response

2.8K
Inositol-requiring kinase one or IRE1 is the most conserved eukaryotic unfolded protein response (UPR) receptor. It is a type I transmembrane protein kinase receptor with a distinctive site-specific RNase activity. As the binding mechanics of the misfolded proteins with the N-terminal domain of IRE-1 are unclear, three binding models — direct, indirect, and allosteric -- are proposed for receptor activation. Nevertheless, it is known that once a misfolded protein associates with IRE1, it...

Area of Science:

  • Immunology
  • Cardiovascular Biology
  • Molecular Medicine

Background:

  • Inflammasomes are cytosolic protein complexes sensing pathogens and initiating inflammation.
  • The NLRP3 inflammasome activates caspase-1, leading to IL-1β/IL-18 secretion and pyroptosis.
  • Endothelial dysfunction is a key predictor of cardiovascular diseases.

Purpose of the Study:

  • To review the role of NLRP3 inflammasome in oxidative stress and endothelial dysfunction.
  • To explore the mechanisms linking NLRP3 inflammasome activation to endothelial dysfunction.
  • To highlight the contribution of noncoding RNAs and potential therapeutic targets.

Main Methods:

  • Comprehensive literature review.
  • Analysis of molecular mechanisms.
  • Discussion of clinical relevance and therapeutic strategies.

Main Results:

  • NLRP3 inflammasome activation exacerbates oxidative stress and endothelial dysfunction.
  • Reactive oxygen species (ROS) act as key triggers for NLRP3 inflammasome activation.
  • Noncoding RNAs play a role in NLRP3 inflammasome-mediated endothelial dysfunction.

Conclusions:

  • NLRP3 inflammasome activation is pivotal in promoting endothelial dysfunction and cardiovascular risk.
  • Targeting NLRP3 inflammasome and associated pathways presents a promising therapeutic avenue.
