Melanocortin 4 receptor (Mc4r) plays a crucial role in the central control of energy homeostasis, but its role in peripheral organs has not been fully explored. We have investigated the roles of hypothalamus-mediated energy metabolism during Xenopus limb regeneration. We report that hypothalamus injury inhibits Xenopus tadpole limb regeneration. By loss of function and gain of function studies, we show that Mc4r signalling is required for limb regeneration in regeneration competent tadpoles and stimulates limb regeneration in later stage regeneration-defective tadpoles. It regulates limb regeneration through modulating energy homeostasis and ROS production. Even more interestingly, our results demonstrate that Mc4r signalling is regulated by innervation and α-MSH substitutes for the effect of nerves in limb regeneration. Mc4r signalling is also required for mouse digit regeneration. Thus, our findings link vertebrate limb regeneration with Mc4r mediated energy homeostasis and provide a new avenue for understanding Mc4r signaling in the peripheral organs. Zhang et al. describe a requirement for melanocortin receptor 4 (Mc4r) signaling in tadpole limb and mouse digit regeneration. They show that Mc4r signaling regulates energy homeostasis and ROS production in the regenerating limb. In addition, α-MSH/Mc4r signaling can substitute for the effect of innervation on limb regeneration.
