Summary
Nutrigenomics uses genomics to study diet-gene interactions, revealing how nutrition impacts gene expression and chronic disease risk. This science enables personalized nutrition for improved health outcomes.
Area of Science:
- Nutrigenomics integrates genomics, biochemistry, and epidemiology.
- Focuses on diet-gene interactions and their health effects.
Context:
- Nutrition is a key environmental factor influencing gene expression.
- Characterization of the human genome enables advanced nutrigenomic research.
- Chronic diseases like cancer, T2DM, obesity, and CVD are studied.
Purpose:
- To understand the etiologic aspects of chronic diseases.
- To identify dietary components with beneficial or detrimental health effects.
- To explore the link between nutrigenetics and individual responses to nutrition.
Summary:
- Nutrigenomics applies high-throughput genomics to diet-gene interactions.
- It examines how nutrition influences gene expression and health.
- Nutrigenetics studies genetic variations in response to diet.
Impact:
- Emerging theories suggest a shift towards personalized dietetic interventions.
- Future diets will integrate nutritional status, needs, and genotype.
- Genomic, proteomic, and metabolomic analyses will define the "nutritional phenotype".

01:29Pharmacogenomics: 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...
01:29Pharmacogenetics and Pharmacogenomics: Overview
Pharmacogenetics and pharmacogenomics examine how genetic factors influence an individual's response to drugs. While pharmacogenetics focuses on the impact of specific genetic variants on drug effects, pharmacogenomics takes a broader approach, studying how genetic variation across populations contributes to differences in drug responses. These fields aim to explain why individuals may experience varying levels of efficacy or adverse reactions to the same medication.Variability in drug...
01:29Pharmacogenetic 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...
01:27Pharmacogenetics 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...
02:50Combination Therapies and Personalized Medicine
Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...
