The ability to adapt to changing environmental stimuli, such as the availability of food, is essential for the survival of species. As such, complex mechanisms have evolved to maintain metabolic homeostasis during periods of nutritional challenge. In 2007, the Fibroblast Growth Factor 21 (FGF21) was identified as a nuclear receptor-regulated hepatokine that is induced during starvation. Since then, considerable effort has been devoted to elucidate the breadth of actions of FGF...

Kisspeptin is a recently identified reproductive hormone which serves as a crucial activator of the Hypothalamic–Pituitary–Gonadal (HPG) axis via stimulation of GnRH neurones. We have previously observed that a single kisspeptin injection increases LH pulsatility while twice daily kisspeptin injections can even advance the menstrual cycle. Furthermore, we have demonstrated that kisspeptin restores LH pulsatility in women with hypothalamic amenorrhoea and can potently...
