Genes Dev. 2021;35(5–6):367–378. doi: 10.1101/gad.345686.120.The longstanding concept of thyroid hormone (TH) action is summarized as the canonical switch model. This study adds important aspects of TH action to our current understanding, modifying this longstanding switch model to a “shift” model.According to the current concept, TH dependent gene...

To read the full abstract: Nature Medicine 2019; 25(3):507-516.This paper shows that quantitative leptin expression is controlled by redundant cis elements and trans factors that interact with the proximal promoter together with a long noncoding RNA.Friedman’s research group discovered the adipocyte hormone leptin more than 20 years ago. They identified loss o...
