To read the full abstract: Science 2018;361:76–81.The tuberal nucleus (TN) is a hypothalamic region which is well described in humans but remains poorly defined in rodents. In this paper, the authors demonstrated by specific and sophisticated techniques the role of somatostatin expressing TN (TNSST) neurons in the control of food intake in mice. Interestingly, their resul...

To read the full abstract: Nat Commun. 2018 19;9:2394.“Somatopause” causes the physiological decline over time in GH secretion leading to low IGF-I levels in aging subjects. GH has been proposed as an anti-aging therapy, but with no evidence of beneficial effects and with some potential risks [1,2]. Therefore, current guidelines do not recommend GH therapy as anti-aging treatme...

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...

3.14. SIRT2 regulates extracellular vesicle-mediated liver-bone communication

L Lin , Z Guo , E He , X Long , D Wang , Y Zhang , W Guo , Q Wei , W He , W Wu , J Li , L Wo , D Hong , J Zheng , M He , Q Zhao

In Brief: These authors studied liver-specific SIRT2 knockout mice to examine how loss of hepatocyte SIRT2 (Sirtuin 2) prevents bone loss in aged mice. Hepatocyte SIRT2 deficiency led to upregulation of Leucine rich α2 glycoprotein (LRG1) in hepatocyte-derived small extracellular vesicles (sEVs) which inhibited osteoclastogenesis in bone marrow.Commentary: Liver-bone communication has been implicated in bone homeostasis.
