Research progress on molecular mechanism of hormone regulation of vitellogenin synthesis in Pancrustacea
Crustaceans and insects are close in evolution and referred to as pancrustaceans.Most vitellogenin is a female-specific protein,which is the precursor of vitellin stored in oocytes.Vitellogenin plays a key role in repro-ductive success.It has been known that juvenile hormone,molting hormone,neuropeptide and insulin-like peptide are the main factors for regulating vitellogenin synthesis in pancrustaceans.The juvenile hormone and ecdysone exert promoting effect on vitellogenesis in insects,while the effect of neuropeptides and insulin-like peptides on the vitellogenesis in a species-specific manner.In addition to the above hormones,the crustacean unique hor-mones,such as eyestalk hyperglycemic hormone(CHH)family and insulin-like androgenic gland hormone(IAG),have inhibitory effects on the vitellogenin synthesis.This review summarized the research progress on the regulat-ory mechanism of vitellogenin synthesis in pancrustaceans,and make detail comparisons of the main hormones and their regulation of vitellogenin synthesis between insects and crustaceans,providing a valuable reference for future studies on reproduction control in cultivated decapod crustaceans.
