Insights

The CYP4A11 gene

Area of Science:

  • Genetics and Cardiovascular Research

Background:

  • Cytochrome P450, family 4, subfamily A, polypeptide 11 (CYP4A11) metabolizes arachidonic acid to 20-hydroxyeicosatetraenoic acid (20-HETE).
  • 20-HETE is vital for maintaining cardiovascular homeostasis.
  • The role of CYP4A11 in coronary artery disease (CAD) requires further investigation.

Purpose of the Study:

  • To investigate the association between the human CYP4A11 gene and coronary artery disease (CAD).

Main Methods:

  • Genotyping of 361 CAD patients and 315 controls for four single-nucleotide polymorphisms (SNPs) in the CYP4A11 gene.
  • Analysis of SNP associations with CAD in total participants, men, and women using case-control studies.
  • Statistical analysis including recessive models and covariate adjustments.

Main Results:

  • A significant difference in the distribution of CYP4A11 SNP3 (rs3890011) genotypes was observed between CAD patients and controls in total participants and men.
  • The recessive model of SNP3 (GG vs CC + GC) was significantly more prevalent in CAD patients.
  • These associations remained significant after adjusting for covariates.

Conclusions:

  • The rs3890011 polymorphism in the CYP4A11 gene may be a novel genetic marker associated with coronary artery disease (CAD).
  • This finding is specific to the Han Chinese population studied.

Pharmacogenetic Phenotypes: Alterations in Pharmacokinetics, Drug Targets and Biologic Milieu

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...

Pharmacogenomics: Identification of New Drug Targets

Advances in genomics have profoundly influenced drug discovery by increasing both the speed and accuracy of pharmaceutical development. Pharmacogenomics, which examines how genetic variation influences drug response, facilitates the identification of novel therapeutic targets and enables patient stratification for personalized treatment. These strategies contribute to improved drug efficacy, minimized adverse effects, and more efficient clinical trial design.Mapping genetic differences...

Pharmacogenetics of Phase I Enzymes: Cytochrome P450 Isozymes

Cytochrome P450 (CYP450) enzymes are a superfamily of heme-containing monooxygenases that play a pivotal role in Phase I drug metabolism by catalyzing oxidation and reduction reactions.These enzymes transform lipophilic xenobiotics into more hydrophilic metabolites, facilitating subsequent Phase II conjugation and eventual excretion. The CYP450 family is classified into families (e.g., CYP1–CYP3) and subfamilies (e.g., CYP2A, CYP2C), based on amino acid sequence homology.CYP450 isoenzymes,...

Pharmacogenetics of Drug Targets: β₂-Adrenergic Receptors, Apo E, Thymidylate Synthase

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...

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...

Pharmacogenetics of Drug Transporters: P-Glycoprotein and Solute Carrier Transporters

The pharmacogenetics of drug transporters is increasingly recognized as a critical factor influencing interindividual variability in drug absorption, distribution, and elimination. These membrane-bound proteins regulate drugs' movement across cellular barriers by actively pumping them out (efflux) or facilitating their uptake (influx). Among the major transporter families, ATP-binding cassette (ABC) and solute carrier (SLC) transporters play particularly prominent roles. Genetic polymorphisms...
