Summary
Genetic variations in the endothelial nitric oxide synthase (eNOS) gene, like Glu298Asp and -786T/C, are linked to cardiovascular diseases. These eNOS polymorphisms affect nitric oxide production, influencing disease susceptibility.
Area of Science:
- Molecular Biology
- Genetics
- Cardiovascular Science
Background:
- Endothelial nitric oxide synthase (eNOS) produces nitric oxide (NO), crucial for endothelial function.
- Dysfunctional NO production is implicated in various diseases.
- Genetic variations (polymorphisms) in the eNOS gene can alter NO bioavailability.
Purpose of the Study:
- To review the role of common eNOS gene polymorphisms in disease susceptibility.
- To highlight the functional significance of specific eNOS variants.
- To explore the association between eNOS polymorphisms and cardiovascular diseases.
Main Methods:
- Literature review of studies investigating eNOS gene polymorphisms.
- Analysis of functional data on eNOS variants (Glu298Asp, -786T/C, intron 4 VNTR).
- Examination of epidemiological evidence linking polymorphisms to disease outcomes.
Main Results:
- The Glu298Asp (rs1799983) and -786T/C (rs2070744) polymorphisms are significantly associated with cardiovascular diseases.
- The intron 4 variable number tandem repeat also influences disease risk.
- These eNOS variants impact NO production and endothelial function.
Conclusions:
- Specific eNOS gene polymorphisms play a significant role in the genetic predisposition to cardiovascular diseases.
- Understanding these genetic factors is important for assessing disease risk and developing targeted interventions.
- eNOS variants contribute to the onset of complex diseases beyond cardiovascular conditions.

01:28Nitric Oxide Signaling Pathway
5.2K
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...

Genetic variations significantly influence drug response through pharmacokinetics, receptor interactions, and biologic milieu modifications. Pharmacokinetic alterations impact drug metabolism and clearance, affecting efficacy and toxicity. Variants in drug-metabolizing enzymes, such as CYP2C9 and CYP2C19, alter drug activation and elimination. For example, CYP2C9 loss-of-function variants require lower warfarin doses to prevent excessive bleeding, while CYP2C19 variants reduce clopidogrel...

Genetic polymorphisms in drug targets have emerged as critical determinants of interindividual variability in drug response and toxicity. Pharmacogenomic investigations increasingly focus on identifying these variations to personalize and optimize therapeutic interventions. A drug target may be a receptor, enzyme, or signaling protein involved in pharmacologic responses or disease-related pathways. While early pharmacogenetic studies focused primarily on drug metabolism, current research...

1.1K
Coronary Artery Disease (CAD) originates from a series of events that impair the function of coronary arteries, the blood vessels responsible for delivering oxygen-rich blood to the heart muscle. The pathophysiology of CAD is closely linked to atherosclerosis, a chronic inflammatory and lipid-driven condition affecting the vascular endothelium.1. Endothelial DamageThe process begins with damage to the vascular endothelium, which serves as a protective barrier between the blood and the vessel...

The human genome is over 99.9% identical between individuals, yet genetic differences exist at millions of bases. The human genome contains approximately 3 million variant positions per individual, many of which are heterozygous, contributing to genetic diversity and individual traits. Genetic variations include single-nucleotide polymorphisms (SNPs), insertions, deletions, and copy number variations (CNVs).SNPs, the most common variation, involve single-base changes in DNA. These can be...

Coronary Artery Disease (CAD): An Overview with Scientific InsightsCoronary Artery Disease (CAD), often referred to as C-A-D, is a prevalent blood vessel disorder classified under the broader category of atherosclerosis. Atherosclerosis is a pathological process characterized by the hardening and narrowing of arteries due to the accumulation of atherosclerotic plaques. These plaques are composed of cholesterol, fatty substances, inflammatory cells, calcium, and fibrin, reducing blood flow to...
