Bursicon hormone
WebEclosion assays are experimental procedures used to study the process of eclosion in insects, particularly in the model organism Drosophila melanogaster (fruit flies). Eclosion is the process in which an adult insect emerges from its pupal case, or a larval insect hatches from its egg. In holometabolous insects, the circadian clock regulates the timing of adult … WebOct 1, 2008 · If Bursicon is the hormone that initiates EMT in the wing epithelia through Rickets, mutations in bursicon and its likely heterodimer partner pupal would be expected to mimic rickets. To test this hypothesis, the strongest bursicon alleles, burs Z4410 and burs Z5569, were chosen.

WebCitation 18 The neurohormone Bursicon is the crucial hormone responsible for the coordination of those final steps of adult ecdysis. The molecular identity of Bursicon remained unknown for decades until the CG13419 locus (called bursicon or burs, hereafter called burs-α) was identified to be responsible for wing inflation. Citation 6 The molecular structure of the hormone has been characterized rather recently. Bursicon is a 30 kDa neurohormone heterodimeric protein which is encoded by CG13419 gene and made of two cysteine knot subunits, Burs-α and Burs-β.
