Adipose tissue metabolism is closely linked to insulin resistance, and differential fat distributions are associated with disorders like hypertension, diabetes, and cardiovascular disease. Adipose tissues vary in their impact on metabolic risk due to diverse gene expression profiles, leading to differences in lipolysis and in the production and release of adipokines and cytokines, thereby affecting the function of other tissues. In this paper, the roles of the various adipose tissues in obesity are summarized, with particular focus on mitochondrial function. In addition, we discuss how a functionally mitochondrial-targeted compound, the modified fatty acid tetradecylthioacetic acid (TTA), can influence mitochondrial function and decrease the size of specific fat depots.
脂肪组织代谢与胰岛素抵抗密切相关,不同的脂肪分布与高血压、糖尿病和心血管疾病等病症有关。由于基因表达谱不同,脂肪组织对代谢风险的影响各异,导致脂解以及脂肪因子和细胞因子的产生与释放存在差异,进而影响其他组织的功能。本文总结了各种脂肪组织在肥胖中的作用,尤其关注线粒体功能。此外,我们还讨论了一种具有线粒体靶向功能的化合物——修饰脂肪酸十四烷基硫代乙酸(TTA),如何影响线粒体功能并减小特定脂肪储存库的大小。
