چکیده

The purpose of our study was to investigate whether the Trp64Arg polymorphism in beta3-AR gene and the -3826A/G polymorphism in the UCP1 gene were associated with the reduction in energy expenditure and fat oxidation both in resting and aerobic exercise in Japanese. Eighty-six nonobese young healthy Japanese were recruited. Energy expenditure was measured using indirect calorimetry. The subjects performed an aerobic exercise program at 60% of their maximal heart rate for 30 minutes. The level of fat oxidation at rest and aerobic exercise of the male subjects with Trp/Arg of the beta3-AR gene was significantly lower than that of the Trp/Trp genotype. No difference in FO(0-30) was observed in the female subjects. There was no association between UCP-1 polymorphism and energy expenditure during aerobic exercise. It was revealed that the Trp64Arg polymorphism in beta3-AR gene is associated with reduction of fat oxidation both in resting and aerobic exercise in healthy, young Japanese males.

Investigation of adrenoceptor genes (β2 & β3) in women with polycystic ovary syndrome

Background: Genetic polymorphism is responsible for variations and individual differences. Polymorphism is a major factor of complex diseases with unknown etiology and cancer. Inconsistency in the symptoms of polycystic ovary syndrome (monthly disorder, hirsutism, obesity, diabetes, infertility) is one of the major pathological complications of this syndrome. The present study was conducted to ...

The Trp64Arg mutation of the beta3 adrenergic receptor gene has no effect on obesity phenotypes in the Québec Family Study and Swedish Obese Subjects cohorts.

The beta adrenergic system plays a key role in regulating energy balance through the stimulation of both thermogenesis and lipid mobilization in brown and white adipose tissues in human and various animal models. Recent studies have suggested that a missense Trp64Arg mutation in the beta3 adrenergic receptor (ADRB3) gene was involved in obesity and insulin resistance. We have investigated the e...

ADRB3 Polymorphism Associated with BMI Gain in Japanese Men

OBJECTIVE The aim of this study was to evaluate the association between the Trp64Arg polymorphism in the beta3-adrenergic receptor gene (ADRB3: rs4994) and BMI and serological and anthropometric data in healthy Japanese. METHODS Healthy Japanese recruited in a large-scale integrated manufacturing facility in Japan (N = 1355; age: 37.25 ± 9.43; BMI: 22.86 ± 3.46) were eligible for analysis. Th...

Chronic effects of aerobic exercise on gene expression of LOX-1 receptor in the heart of rats fed with high fat diet

Objective(s):Lectin-like low density lipoprotein receptor (LOX-1) has pivot role in vascular complications, which is upregulated in numerous pathological conditions. Since exercise has beneficial effects in prevention of hyperlipidemic complications, present study examined protective effects of aerobic exercise through reduction of LOX-1 expression in heart during dyslipidemia. Materials and M...

Individual Responsiveness to Exercise-Induced Fat Loss and Improvement of Metabolic Profile in Young Women is Associated with Polymorphisms of Adrenergic Receptor Genes.

The effectiveness of physical exercise on fat loss and improvement of aerobic capacity varies considerably between individuals. A strong linkage exists between common allelic variants of the adrenergic receptor genes and weight gain, as well as changes in body composition. Therefore we aimed to check if body composition and metabolic variables were modulated by the ADRB2 (Gly16Arg and Glu27Gln)...
