细胞因子如白细胞介素-6诱导Stat 3的酪氨酸和丝氨酸磷酸化,导致Stat 3应答基因的激活。我们提供的证据表明,Stat 3存在于培养细胞和原代组织的线粒体中,包括肝脏和心脏。在Stat 3 −/−细胞中,电子传递链(ETC)的复合物I和II的活性显著降低。我们确定了Stat 3突变体,选择性地恢复蛋白质的功能,作为一个转录因子或其功能内的ETC。在小鼠不表达Stat 3在心脏,也有选择性的缺陷,在活动的复合物I和II的ETC。这些数据表明,Stat 3是必需的ETC的最佳功能,这可能使它能够协调响应细胞内稳态。
Cytokines such as interleukin-6 induce tyrosine and serine phosphorylation of Stat3 that results in activation of Stat3-responsive genes. We provide evidence that Stat3 is present in the mitochondria of cultured cells and primary tissues, including the liver and heart. In Stat3−/− cells, the activities of complexes I and II of the electron transport chain (ETC) were significantly decreased. We identified Stat3 mutants that selectively restored the protein's function as a transcription factor or its functions within the ETC. In mice that do not express Stat3 in the heart, there were also selective defects in the activities of complexes I and II of the ETC. These data indicate that Stat3 is required for optimal function of the ETC, which may allow it to orchestrate responses to cellular homeostasis.
