In vertebrates, gonadotropin-releasing hormone (GnRH) regulates gonadal maturation by stimulating the synthesis and release of pituitary gonadotropins. GnRH has also been identified in invertebrates. Crustacea consists of several classes including Cephalocarida, Remipedia, Branchiopoda (e.g., tadpole shrimp), Hexanauplia (e.g., barnacle) and

Endocrinology, 149(8), 3860-3869 (2008-04-26)
We cloned a cDNA encoding a novel (GnRH), named lamprey GnRH-II, from the sea lamprey, a basal vertebrate. The deduced amino acid sequence of the newly identified lamprey GnRH-II is QHWSHGWFPG. The architecture of the precursor is similar to that

General and comparative endocrinology, 161(1), 20-29 (2008-12-17)
The acquisition of a hypothalamic-pituitary axis was a seminal event in vertebrate evolution leading to the neuroendocrine control of many complex functions including growth, reproduction, osmoregulation, stress and metabolism. Lampreys as basal vertebrates are the earliest evolved vertebrates for which

General and comparative endocrinology, 148(1), 22-32 (2006-01-24)
We have identified the first and perhaps only gonadotropin beta-like protein by cDNA cloning in sea lamprey, a member of the oldest lineage of vertebrates, the agnathans. Two pituitary gonadotropins (GTHs: follicle-stimulating hormone (FSH) and luteinizing hormone (LH)) have been
