Insights

Genetic variants in PPAR-alpha, LPL, and TNF-alpha influence cardiovascular risk factors like lipid levels, inflammation, and oxidative status in the Mediterranean population.

Area of Science:

  • Cardiovascular Genetics
  • Atherothrombosis Research
  • Population Health

Background:

  • Atherothrombosis development is linked to established cardiovascular risk factors, with emerging evidence for genetic and non-classical factors.
  • Investigating these factors is crucial for understanding disease progression in diverse populations.

Purpose of the Study:

  • To determine the association between classical and non-classical cardiovascular risk factors and candidate gene polymorphisms in a Mediterranean population.
  • To explore the role of specific gene variants in cardiovascular risk.

Main Methods:

  • A cross-sectional study was conducted on a general Mediterranean population.
  • Prevalence of classical (lipids, blood pressure, BMI, etc.) and non-classical (CRP, oxidative status, etc.) risk factors was assessed.
  • Associations with five gene polymorphisms (ATP-binding cassette transporter A1, PPAR-alpha, LPL, PON1, TNF-alpha) were analyzed.

Main Results:

  • PPAR-alpha-V and LPL-H alleles correlated with lower HDL-c and higher cholesterol/triglyceride ratios.
  • The PPAR-alpha-V allele was linked to elevated C-reactive protein.
  • Homozygotes for LPL-H and TNF-alpha-G alleles exhibited higher oxidative status.

Conclusions:

  • Genetic variants PPAR-alpha-L162V, LPL-HindIII, and TNF-alpha-G-308A are associated with non-classical cardiovascular risk factors.
  • These genetic factors impact lipid profiles, inflammation, and oxidative status, contributing to atherothrombosis risk.

Coronary Artery Disease I: Introduction

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...

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...

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...

Human Genetics

Human genetics provides a profound framework for understanding the interplay between genetic predispositions and human psychology. At the heart of this discipline lies the study of how genes influence physical traits, behaviors, and susceptibility to diseases. Each person carries a unique genetic code that subtly or significantly shapes their psychological and behavioral landscape.
The complex relationship between genetics and psychology is observable through common biological components such...

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...

Genome-wide Association Studies-GWAS

Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
GWAS does not require the identification of the target gene involved in...
