Kisspeptin, the endogenous ligand of the GPR54 receptor, is a key regulator of the hypothalamo-pituitary-gonadal (HPG) axis. GPR54-null mice exhibit reproductive dysfunction and exogenous kisspeptin potently stimulates the HPG axis in rodents, primates and human males. The effects of kisspeptin administration to human females are not known.Aim: To investigate the effects of kisspeptin on luteinising hormone (LH) release during the menstrual cycle in fema...

Sedlin mutations disrupt interactions with pituitary homeobox 1 (Pitx1) and steroidogenic factor 1 (SF1): potential cause of delayed puberty in boys with Spondyloepiphyseal dysplasia tarda (SEDT)

Delayed puberty may occur in some boys affected with X-linked Spondyloepiphyseal dysplasia tarda (SEDT), which is caused by mutations of the gene encoding a 140 amino acid protein designated Sedlin. Sedlin interacts with the pituitary homeobox 1 (Pitx1) and steroidogenic factor 1 (SF1) transcription factors, which are involved in the development and regulation of the hypothalamic-pituitary-gonadal axis. We have therefore investigated the hypothesis that SEDT associated mutatio...
