Summary
This study explored iris constitution and tumor necrosis factor-alpha (TNFalpha) gene variations in Koreans with hypertension. Certain TNFalpha genotypes were associated with hypertension risk and specific iris constitution types.
Area of Science:
- Genetics
- Internal Medicine
- Ophthalmology
Background:
- Iridology analyzes iris pigmentation for diagnosing conditions, with a hereditary basis.
- Tumor necrosis factor-alpha (TNFalpha), a cytokine, is linked to various pathologies, including hypertension.
- Investigating genetic factors in hypertension is crucial for understanding disease mechanisms.
Purpose of the Study:
- To examine the association between iris constitution and TNFalpha gene polymorphism in hypertensive individuals.
- To determine if specific TNFalpha genotypes correlate with hypertension in a Korean population.
- To explore the interplay between genetic predisposition, iris characteristics, and hypertension.
Main Methods:
- Eighty-seven hypertensive patients and 79 controls were recruited.
- Participants were classified based on iris constitution.
- TNFalpha gene polymorphism (genotyping) was determined for all individuals.
Main Results:
- A marginal association (p=0.08) was observed, with lower frequency of TNFalpha GA heterozygote in hypertensive individuals, suggesting potential disease resistance.
- The TNFalpha GG genotype was significantly more frequent (p=0.001) in hypertensive individuals with cardio-renal connective tissue weakness, compared to controls.
- A significant association was demonstrated between TNFalpha gene polymorphism, iris constitution, and hypertension in Koreans.
Conclusions:
- Iris constitution and TNFalpha gene polymorphism are associated with hypertension in the studied Korean population.
- Specific TNFalpha genotypes may influence hypertension susceptibility or resistance, potentially linked to iris characteristics.
- This research highlights the potential of integrating genetic and phenotypic markers for hypertension risk assessment.

01:11Pharmacogenetics 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...
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...
01:29Hypertension II: Pathophysiology
Hypertension is a chronic condition in which the blood's force against artery walls is excessively high, posing risks such as heart disease. The condition's underlying mechanisms involve complex interactions among the cardiovascular, kidney, and autonomic nervous systems.Renin-Angiotensin-Aldosterone System (RAAS): This system significantly influences blood pressure regulation. When blood pressure decreases, the kidneys secrete renin. This enzyme transforms angiotensinogen, a plasma protein,...
