1.3. AstA signaling functions as an evolutionary conserved mechanism timing juvenile to adult transition

D Deveci , FA Martin , P Leopold , NM Romero

To read the full abstract: Curr Biol 2019;29:813–822 e4.In vertebrates, puberty is the critical transitional step which leads to major somatic changes and the acquisition of the reproduction function. At the molecular level, puberty equates to the reactivation of the gonadotropic axis after a period of childhood quiescence, and hence increases sex steroid production. This reactivati...

1.4. Estrogen signaling in arcuate Kiss1 neurons suppresses a sex-dependent female circuit promoting dense strong bones

CB Herber , WC Krause , L Wang , JR Bayrer , A Li , M Schmitz , A Fields , B Ford , Z Zhang , MS Reid , DK Nomura , RA Nissenson , SM Correa , HA Ingraham

To read the full abstract: Nat Commun 2019;10:163.Central estrogen signaling via estrogen receptor alpha (ERα) coordinates energy expenditure, reproduction and, in concert with peripheral estrogen, impacts skeletal homeostasis. Here, the authors showed that eliminating ERα in kisspeptin arcuate nucleus neurons resulted in high bone mass phenotype in female mice only.<p clas...

1.5. CRISPR-mediated activation of a promoter or enhancer rescues obesity caused by haploinsufficiency

N Matharu , S Rattanasopha , S Tamura , L Maliskova , Y Wang , A Bernard , A Hardin , WL Eckalbar , C Vaisse , N Ahituv

To read the full abstract: Science 2019;363(6424).A wide range of human diseases result from haploinsufficiency, where gene expression is decreased as compared to normal conditions. Haploinsufficiency is a typical mechanism in autosomal dominant disorders. Rare mutations in Sim1 or Mc4r are models of haploinsufficiency causing severe early-onset obesity with hyperphagia...

1.6. Regulation of feeding by somatostatin neurons in the tuberal nucleus

SX Luo , J Huang , Q Li , H Mohammad , CY Lee , K Krishna , AM Kok , YL Tan , JY Lim , H Li , LY Yeow , J Sun , M He , J Grandjean , S Sajikumar , W Han , Y Fu

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...
