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: This study provides evidence for the role of miR-137/325 in obesity-induced hypogonadism (OIH) and metabolic dysfunction.Obesity is associated with different forms of gonadal and reproductive dysfunction, including central male hypogonadism (1, 2). Although weight loss is the ideal therapeutic strategy for patients with OIH, significant weight loss is usually difficult to achieve only with lifestyle changes. Hence, androgen administration ...
