Human UCP2 and UCP3, expressed in yeast, were studied to establish their high affinity regulatory ligands. UCPn were reconstituted into liposomes and assayed for fatty acid (FA)-induced H efflux. All natural long chain FAs activated UCP2and UCP3-mediated H translocation. Coenzyme Q10 had no further significant activating effect. Evaluated parameters of FA activation (FA cycling) kinetics reveal...
objective(s):high-intensity interval training (hiit) increases energy expenditure and mechanical energy efficiency. although both uncoupling proteins (ucps) and endothelial nitric oxide synthase (enos) affect the mechanical efficiency and antioxidant capacity, their effects are inverse. the aim of this study was to determine whether the alterations of cardiac ucp2, ucp3, and enos mrna expressio...
مقدمه: داروهای مهار کننده سیستم رنین آنژیوتانسین مستقل از اثرات همودینامیکی با عمل در سطح سلولی مولکولی میتوانند اثرات محافظتی در سیستم قلب و عروق اعمال نمایند اما مکانیسم عملکرد آنها همچنان ناشناخته است. یکی از منابع اصلی تولید رادیکالهای آزاد اکسیژن (ros)در ایسکمی رپرفیوژن میوکارد (nadph oxidase)nox2 است که بیان و فعالیت آن توسط آنژیوتانسین القا میگردد. در مقابل پروتئینهای uncoupling (ucp...
Intramyocellular lipids (IMCL) and mitochondrial uncoupling protein-3 (UCP3) have been implicated in the development of muscular insulin resistance. This study aimed to investigate the role of IMCL and UCP3 in the development of glucose intolerance and muscular insulin resistance during 12 weeks of an obesity-inducing 'cafeteria-style' diet alone (CAF), or in conjunction with exercise training ...
An efficient uncoupling process is generally considered to have a protective effect on the aging muscle by slowing down its age-related decay. Genetic polymorphisms in the Uncoupling Protein 3 (UCP3) gene, whose product is mainly expressed in skeletal muscle, were suggested to be associated with hand grip (HG) performances in elderly populations. Considering the population specificity of the qu...
Malonyl-CoA functions as a mediator in the hypothalamic sensing of energy balance and regulates the neural physiology that governs feeding behavior and energy expenditure. The central administration of C75, a potent inhibitor of the fatty acid synthase (FAS), increases malonyl-CoA concentration in the hypothalamus and suppresses food intake while activating fatty acid oxidation in skeletal musc...
Cellular adaptations to endurance training are influenced by the intensity and duration of exercise. To examine the impact of exercise intensity and duration on the acute transcriptional regulation of metabolic genes in red (RG) and white (WG) gastrocnemius muscle, rats completed either low-intensity [ approximately 50% maximal O2 uptake (VO2 max)] treadmill exercise (LIE) for 45 min, LIE for 1...
The mRNA expressions of UCP2 and UCP3, two newly described genes with high sequence homology to the uncoupling protein UCP1 in brown adipose tissue (BAT), were examined in two skeletal muscles (gastrocnemius and soleus) as well as in interscapular BAT (IBAT) of the rat in response to food deprivation and controlled refeeding. In IBAT (a tissue highly dependent on lipids for thermogenesis), the ...
Uncoupling proteins (UCP), specific mitochondrial proton transporters that function by uncoupling oxidative metabolism from ATP synthesis, are involved in thermoregulation and control of energy expenditure. The hibernoma-derived T37i cells, which possess functional endogenous mineralocorticoid receptors (MR), can undergo differentiation into brown adipocytes. In differentiated T37i cells, UCP1 ...
