【Abstract】 The recent research on the regulation of growth and growth hormone secretion in amphibians and reptiles is reviewed. Recent studies show the structure and function of growth hormone (GH) is highly conserved among vertebrate species including the amphibians and reptiles. Functional studies support a growth promoting role for GH in amphibians and reptiles. The GH somatomedin (insulin like growth factor, IGF) axis is present in herpetofauna. Hypothalamic regulation of GH secretion in herpetofauna is generally less specific than in mammals, a situation that is also found in fishes and birds. There are great applied prospects in promotion of growth and development through exogenous growth hormone in amphibians and reptiles.更多还原
