Abstract

Background:

Metabolic syndrome (MetS) is defined as a metabolic dysfunction characterized by the co-occurrence of multiple risk factors. Our study aimed to elucidate the effects of ADIPOQ rs266729, rs17300539, and rs2241766, AGT rs699 and rs4762, AGTR1 rs5186, AGTR2 rs11091046, ApoC-III rs2854116 and rs2854117, NR3C1 rs10052957 and rs41423247, and GNB3 rs5443 gene polymorphisms on MetS.

Methods And Results:

A total of 200 patients who met the diagnostic criteria for MetS at the Internal Medicine Outpatient Clinic of Istanbul University, Faculty of Medicine, between 01.08.2022 and 20.05.2023, and 100 healthy controls were included in our study. ADIPOQ rs17300539 GA, AGT rs699 TT, AGTR1 rs5186 AC, and AGTR2 rs11091046 CC genotypes were more frequently observed in patients diagnosed with MetS compared to healthy controls (p < 0.05 for all). MetS patients with AGT rs699 TT genotype had a higher incidence of hypertension compared to individuals with CC/CT genotype of the same polymorphism (p = 0.047). Individuals with ADIPOQ rs17300539 AA/AG and NR3C1 rs41423247 CC genotypes were found to have higher mean waist circumferences compared to others (p < 0.05 for all). Individuals with ADIPOQ rs17300539 AA/AG, NR3C1 rs10052957 GG, and AGT rs4762 GA/AA genotypes exhibited significantly higher incidence of nephropathy. Individuals with ADIPOQ rs17300539 AA/AG and NR3C1 rs10052957 GG genotypes had a significantly higher incidence of retinopathy compared to others.

Conclusions:

The study demonstrated that the ADIPOQ rs17300539, AGT rs699, AGTR1 rs5186, and AGTR2 rs11091046 polymorphisms are associated with an increased susceptibility to MetS. Significant results concerning clinical features and complications were also observed. Further research is necessary to elucidate the relationship between susceptibility to MetS, clinical and laboratory characteristics, and epigenetic modifications.

Obesity

Obesity

The Body Mass Index (BMI) is a numerical value derived from a person's weight and height, used to categorize individuals into weight ranges. It is calculated using the formula: weight in kilograms divided by height in meters squared. Obesity is a health condition characterized by excessive accumulation of adipose tissue that poses health risks, often diagnosed with a BMI ≥ 30. This excess fat storage occurs when surplus dietary calories are converted into triglycerides and stored in...

Human Genetics

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...

GPCRs Regulate Adenylyl Cylase Activity

GPCRs Regulate Adenylyl Cylase Activity

Some GPCRs transmit signals through adenylyl cyclase (AC), a transmembrane enzyme. AC helps synthesize second messenger cyclic adenosine monophosphate (cAMP). AC catalyzes cyclization reaction and converts ATP to cAMP by releasing a pyrophosphate. The pyrophosphate is further hydrolyzed to phosphate by the enzyme pyrophosphatase, which drives cAMP synthesis to completion. However, cAMP is rapidly degraded to 5′ AMP by the enzymes phosphodiesterase (PDE), preventing overstimulation of...

Transducer Mechanism: Enzyme-Linked Receptors

Transducer Mechanism: Enzyme-Linked Receptors

Enzyme-linked receptors are cell-surface receptors acting as an enzyme or associating with an enzyme intracellularly. They make excellent drug targets. Drugs can bind to the extracellular ligand-binding domain or directly affect their enzymatic domain and alter their activity.
Major types that are helpful drug targets include:

Overview of Carbohydrate Metabolism

Overview of Carbohydrate Metabolism

Carbohydrate metabolism is a fundamental biochemical process that ensures a constant supply of energy to living cells. The most important carbohydrate is glucose, which can be broken down via glycolysis to enter into the Krebs cycle and eventually lead to the production of ATP through oxidative phosphorylation.
Glucose transport into cells is facilitated by a family of transport proteins called GLUT (Glucose Transporters). GLUT4 is the primary glucose transporter for insulin-stimulated glucose...

Regulation of Food Intake

Regulation of Food Intake

Short-term regulation of food intake primarily involves neural signals from the gastrointestinal (GI) tract, blood nutrient levels, and GI tract hormones. Communication between the gut and brain via vagal nerve fibers plays a significant role in evaluating the contents of the gut. Clinical studies have shown that protein ingestion produces a more prolonged response in these nerve fibers compared to an equivalent amount of glucose. Additionally, the activation of stretch receptors caused by GI...
