5.11. Dicer ablation in Kiss1 neurons impairs puberty and fertility preferentially in female mice

J Roa , M Ruiz-Cruz , F Ruiz-Pino , R Onieva , MJ Vazquez , MJ Sanchez-Tapia , JM Ruiz-Rodriguez , V Sobrino , A Barroso , V Heras , I Velasco , C Perdices-Lopez , C Ohlsson , MS Avendano , V Prevot , M Poutanen , L Pinilla , F Gaytan , M Tena-Sempere

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...

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 ...
