Homeobox C4 (HOXC4) links metabolic pathways and correlates inversely with mouse body weight and positively with Ucp1 expression in mouse adipose tissue. Gain- and loss-of-function experiments in mice demonstrated HOXC4's essential role in promoting adipose thermogenesis and providing metabolic benefits. HOXC4 interacts with the nuclear receptor coactivator 1 cofactor via its hexapeptide motif to activate Ucp1 transcription, revealing a novel mechanism of thermogenic gene regulation.
同源盒C4（HOXC4）连接代谢途径，与小鼠体重呈负相关，与小鼠脂肪组织中的Ucp1表达呈正相关。在小鼠中进行的功能获得和功能丧失实验表明，HOXC4在促进脂肪产热和提供代谢益处方面起着至关重要的作用。HOXC4通过其六肽基序与核受体辅激活因子1辅因子相互作用，以激活Ucp1转录，揭示了一种产热基因调控的新机制。
