Summary
Genetic variations influence Vitamin E (VE) status by affecting its absorption and metabolism. Identifying these genetic factors is key for personalized nutrition and understanding VE
Area of Science:
- Nutritional Genomics
- Biochemistry
- Human Genetics
Background:
- Vitamin E (VE) encompasses tocopherols and tocotrienols, with α-tocopherol being the most biologically active form.
- Individual Vitamin E status is influenced by dietary intake, absorption efficiency, and metabolic breakdown.
- Genetic variations in relevant genes can significantly modulate these factors affecting Vitamin E levels.
Purpose of the Study:
- To identify genetic variations impacting fasting blood Vitamin E concentration and α-tocopherol bioavailability.
- To explore the role of genetic factors in personalized nutrition strategies.
- To lay the groundwork for predicting individual Vitamin E status based on genotype.
Main Methods:
- Utilized genome-wide association studies (GWAS) and candidate gene association studies.
- Focused on identifying single nucleotide polymorphisms (SNPs) associated with Vitamin E levels.
- Investigated genetic variations influencing Vitamin E absorption and catabolism.
Main Results:
- Identified several single nucleotide polymorphisms (SNPs) associated with fasting blood Vitamin E concentration.
- Established a connection between specific genetic variations and α-tocopherol bioavailability.
- Highlighted the influence of genetic factors on Vitamin E metabolism and status.
Conclusions:
- Genetic variations play a significant role in determining an individual's Vitamin E status.
- Further research is needed to identify all relevant SNPs and other genetic variations (e.g., copy number variants, epigenetic modifications).
- This research holds promise for personalized nutrition and future clinical trials on Vitamin E isoforms.

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...

68
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...

2.7K
Vitamins, derived from the Latin word for life, are essential organic substances required in small quantities for optimal growth and overall well-being. Unlike other organic nutrients, vitamins don't act as sources of energy or building materials but rather facilitate these nutrients' utilization by the body. Vitamins are predominantly coenzymes, assisting enzymes in specific chemical actions, like the oxidation of glucose for energy involving B vitamins. Most vitamins are not produced...

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...

Sequencing of the human genome has opened up several best-kept secrets of the genome. Scientists have identified thousands of genome variations that exist within a population. These variations can be a single nucleotide or a larger chromosomal variation.
Copy number variations or CNVs are the structural variations that cover more than 1kb of DNA sequence. The single nucleotide polymorphism (SNP), on the other hand, is a single nucleotide change or a point mutation that is found in more than 1%...
