Melanin-concentrating hormone: A neuropeptide hormone affecting the relationship between photic environment and fish with special reference to background color and food intake regulation.
Melanin-concentrating hormone (MCH) was first discovered in the pituitary gland of the chum salmon for its role in the regulation of skin pallor. Currently, MCH is known to be present in the brains of organisms ranging from fish to mammals. MCH has been suggested to be conserved principally as a central neuromodulator or neurotransmitter in the brain. Indeed, MCH is considered to regulate food intake in mammals. In this review, profiles of MCH in the brain and pituitary gland of teleost fishes are described, focusing on the involvement of MCH in background color adaptation and in food intake regulation.
