Abstract

Mitochondrial uncoupling protein (UCP), mitochondrial transporters, function as a proton channel and increase thermogenesis. UCP1 is expressed in brown adipose tissues (BAT), UCP2 is widely expressed in multiple tissues, while UCP3 is expressed in skeletal muscle. Thus, UCPs, especially UCP3, in skeletal muscles is a good candidates for prevention of obesity and diabetes. However, the role of UCP3 in skeletal muscle for energy expenditure and obesity has been controversial. There is some evidence that the UCP3 is possibly regulated by energy substrate, such as lipid and glucose. These observations suggest that increased energy substrate entry in muscle results in an increase in UCP3 expression which leads to an increase in energy expenditure.
