Insights

Genetic variations in vascular endothelial growth factor (VEGF) are linked to preterm birth and serious infant complications. Specific VEGF polymorphisms increase risks for necrotizing enterocolitis and acute renal failure in low birth weight infants.

Area of Science:

  • Perinatal Medicine
  • Medical Genetics
  • Neonatology

Background:

  • Low birth weight (LBW) infants face higher risks of perinatal complications due to immature vascular systems.
  • Vascular Endothelial Growth Factor (VEGF), crucial for embryonic blood vessel development, is implicated in these complications.

Purpose of the Study:

  • To investigate the association between functional genetic polymorphisms of VEGF and the risk of preterm birth or perinatal morbidity in LBW infants.

Main Methods:

  • Genotyping of VEGF T-460C, C-2578A, and G+405C polymorphisms in 128 LBW infants using real-time PCR or PCR-RFLP.
  • Comparison of VEGF genotypes with 200 healthy, term neonates.

Main Results:

  • The VEGF+405 C allele was more prevalent in LBW infants (OR: 1.29).
  • VEGF -2578A allele carrier status was an independent risk factor for necrotizing enterocolitis (NEC) (aOR: 2.77).
  • VEGF -2578AA genotype carriers showed a reduced risk of acute renal failure (ARF) (aOR: 0.2).

Conclusions:

  • VEGF G+405C polymorphism may be associated with an increased risk of preterm birth.
  • VEGF C-2578A polymorphism appears to play a role in the pathogenesis of perinatal complications like NEC and ARF in LBW infants.

Regulation of Angiogenesis and Blood Supply

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 hydroxylase and factor...

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...
Teratogenicity01:07

Teratogenicity

The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...

Pharmacogenetics of Drug Metabolism: Overview

Genetic polymorphism in drug metabolism is crucial to the inter-individual variability observed in drug responses. Drug metabolism primarily involves the chemical modification of drugs and other xenobiotics to enhance their elimination by increasing their polarity. Two main classes of enzymes mediate this biotransformation process: Phase I enzymes, primarily cytochrome P450s, catalyze oxidation and reduction reactions, while other enzymes, such as esterases, mediate hydrolysis, and Phase II...

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...

Principles of Pharmacogenetics: Types of Genetic Variants

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...
