UCP-3: regulação da expressão gênica no músculo esquelético e possível relação com o controle do peso corporal

Abstract: Uncoupling proteins constitute a subgroup of mitochondrial carrier proteins that are located in the inner mitochondrial membrane. By dissipating proton gradients, they act to uncouple respiration from oxidative phosphorylation and convert fuel to heat. Four homologous UCP isoforms have been identified. UCP-1, the first UCP to be described, is found exclusively in brown adipose tissue, UCP-2 in several tissues, UCP-3 in human skeletal muscle and rat brown adipose tissue and skeletal muscle, whereas UCP-4 is exp… Show more

“…Several studies 31,32,12 , assessing the effect of weight training on REE have reported increases in energy expenditure, lean body mass, fat free mass, and even muscle mass. However, changes in resting energy expenditure may be due to factors independent of lean body mass, the main such factor being muscle mass, which has led to increased research interest in other components of energy expenditure, including genetic factors 33 , and dietary aspects, Age (years) 58 (7) 57 (9) 60 (5) 60 (7) 0.7…”

“…Moreover, other investigations on energetic metabolism have evidenced that high levels of FFAs regulate the gene expression of the UCP-3 in the skeletal muscle, liver, pancreas, and other tissues, and that this protein family is in close association with obesity, fasting, and exercise 15,16 . These and other effects of low-intensity ultrasound therapy (LIUST) on the lipid and glycemic metabolism fostered several new possibilities for therapy applications in the treatment of obesity and type-II diabetes mellitus (DM 2 ).…”

“…Embora seus mecanismos de ação não estejam totalmente estabelecidos, sua função termogênica no TAM é relatada em alguns estudos (KNUDSEN et al, 2014;LIU et al, 2013). A família das proteínas desacopladoras auxiliam no combate a obesidade, devido a sua localização na membrana interna mitocondrial relacionada a produção de energia sob a forma de calor (KLAUS et al, 2012;DEPIERI et al, 2004). Em pesquisas realizadas com ratos observou-se que o aumento da expressão da UCP1 tanto em TAB quanto em músculo esquelético conduziu ao aumento no gasto energético (KLAUS et al, 2005;STEFL et al, 1998).…”

“…O aumento da expressão do gene UCP2 na presente pesquisa confirma os achados na literatura, a qual mostra que as proteínas desacopladoras produzem energia, desencadeando uma maior produção de calor e elevando a taxa metabólica de repouso por quilograma de peso nos pacientes após a cirurgia bariátrica. A análise das UCPs tornam evidente que a energia intracelular das células do tecido adiposo desempenham importante função no metabolismo energético, sendo possíveis alvos para intervenções nutricionais personalizadas e abordagens farmacológicas, visando aumentar o gasto energético e oxidação de gordura (KOPECKY et al, 2004;DEPIERI et al, 2004).…”
