As the nation gets fatter, the incidence of diabetes is also rising. The brain is now emerging as a critical mediator of blood sugar control, re-directing focus away from the traditional pancreas-centred model. The enzyme glucokinase (GK) acts as a glucose sensor in many tissues including glucose-sensitive neurones within the hypothalamic arcuate nucleus. However, the role of GK here is unclear. We investigated the role of arcuate GK in glucose homeostasis in both healthy and ...

Background: Limited data exists on the hormonal mediators connecting metabolism and reproduction. Animal studies show that the reproductive hormone, kisspeptin, may also be important in metabolism. We investigated the effects of kisspeptin on human metabolism for the first time, to explore possible kisspeptin-mediated links between reproduction and metabolism.Methods: We performed intravenous glucose tolerance tests (IVGTTs) in 15 healthy men (age 25&#17...
