An investigation of the molecular complexities that regulate molting in decapod crustaceans
MetadataShow full item record
Molting in decapod crustaceans is regulated by the interaction of two hormones, molt inhibiting hormone (MIH) and ecdysteroids. Ecdysteroids are steroid hormones secreted from the molting gland or Y-organ (YO) and fluctuations in hemolymph ecdysteroid titers regulate progression through the molt cycle. Secretion of ecdysteroids is controlled by the peptide hormone MIH, which is synthesized and released from the X-organ/sinus gland (XO/SG) complex in the eyestalk ganglia (ESG). The field of crustacean endocrinology has mainly focused on understanding the molecular underpinnings of MIH’s action ...
