Abstract

Hypermetabolism is a prominent feature of burn injury, and altered mitochondria function is presumed to contribute to this state. Recently, brown adipose tissue (BAT) was found to be present not only in rodents but also in humans, and its activity is associated with resting metabolic rate. In this report, we elucidate the relationship between burn injury-induced hypermetabolism and BAT activity and the possible role of the mitochondria-targeted peptide SS31 in attenuating burn injury-induced hypermetabolism by using a rat burn injury model. We demonstrate that burn injury induces morphological changes in interscapular BAT (iBAT). Burn injury was associated with iBAT activation, and this effect was positively correlated with increased energy expenditure. BAT activation was associated with augmentation of mitochondria biogenesis, and UCP1 expression in the isolated iBAT mitochondria. In addition, the mitochondria-targeted peptide SS31 attenuated burn injury-induced hypermetabolism, which was accompanied by suppression of UCP1 expression in isolated mitochondria. Our results suggest that BAT plays an important role in burn injury-induced hypermetabolism through its morphological changes and expression of UCP1.

摘要

代谢亢进是烧伤损伤的一个显著特征,而改变的线粒体功能被认为是导致这种状态的原因之一。最近,人们发现棕色脂肪组织(BAT)不仅存在于啮齿动物中,也存在于人类中,其活性与静息代谢率相关。在本报告中,我们使用大鼠烧伤模型阐明了烧伤诱导的代谢亢进与 BAT 活性之间的关系,以及线粒体靶向肽 SS31 减轻烧伤诱导的代谢亢进的可能作用。我们证明烧伤损伤诱导了肩胛间 BAT(iBAT)的形态变化。烧伤与 iBAT 的激活有关,这种作用与能量消耗的增加呈正相关。BAT 的激活与线粒体生物发生的增加以及分离的 iBAT 线粒体中 UCP1 的表达有关。此外,线粒体靶向肽 SS31 减轻了烧伤诱导的代谢亢进,同时抑制了分离的线粒体中 UCP1 的表达。我们的结果表明,BAT 通过其形态变化和 UCP1 的表达在烧伤诱导的代谢亢进中发挥重要作用。
