To read the full abstract: Nat Commun. 2018 Oct 10;9(1):4194.This study identifies Sirtuin 1 (SIRT1), a fuel-sensing deacetylase, as a molecule that restrains female puberty via epigenetic repression of the puberty-activating gene, Kiss1 in rats.The last few years have brought evidence regarding the epigenetic control of the onset of puberty. It is now cle...

To read the full abstract: Proc Natl Acad Sci U S A. 2018 Nov 6;115(45):E10758–E10767.The authors show for the first time that central AMP-activated protein kinase (AMPK), the major cellular energy sensor, interplays with Kiss1 to control puberty onset.AMPK is an indispensable cellular energy sensor (1). Beside its ability to directly sense ener...
