Thyroid. 2022 Apr;32(4):459-471. doi: 10.1089/thy.2021.0535. PMID: 35044245Brief Summary: This study combines animal model and patient cohort data on the effect of hyperthyroidism and hypothyroidism at birth on adrenal gland development and function. The data revealed reciprocal effects of neonatal hyper- and hypothyroidism on adrenal development, activity of the adrenal steroidogenic pathway a...

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...

Brief summary: A newly developed mouse model of congenital ablation of Dicer in kisspeptin neurons was used to identify a role for miRNAs in kisspeptin neuron activity and control of reproduction.The last few years have seen a shift in paradigm with the discovery of epigenetic mechanisms regulating GnRH neuron activity and thus puberty and reproduction. In particular, miRNAs appear to play a crucial role in the maturation and function of the hypothalamic...
