Gonadotropin-releasing hormone in elasmobranch (electric ray, Torpedo marmorata) brain and plasma: Chromatographic and immunological evidence for chicken GnRH II and novel molecular forms

Gonadotropin-releasing hormone (GnRH) peptides in the brain, testis and plasma of an electric ray ( Torpedo marmorata) were investigated by gel filtration chromatography, reverse phase high performance liquid chromatography and radioimmunoassay with region-specific antisera. In the brain, two major...

description Gonadotropin-releasing hormone (GnRH) peptides in the brain, testis and plasma of an electric ray ( Torpedo marmorata) were investigated by gel filtration chromatography, reverse phase high performance liquid chromatography and radioimmunoassay with region-specific antisera. In the brain, two major forms of GnRH were demonstrated. One form had identical chromatographic and immunological properties to chicken GnRH II, and the second, novel, molecular form had structural features in common with mammalian, chicken II and salmon GnRHs. A minor, early-eluting immunoreactive peak, possibly also a novel GnRH, was also evident. Immunoreactive GnRH was not detected in the testis. In the plasma, a single major early-eluting immunoreactive peak was demonstrated. This peak, identical to the minor peak observed in the brain, is likely to represent a novel form of GnRH which has immunological properties in common with mammalian, chicken II and salmon GnRHs. Immunoreactive GnRH was not detected in the plasma of species from other vertebrate classes, including rabbit, chicken, monitor lizard, clawed toad, frog, cichlid fish and lamprey. The finding of chicken GnRH II in a species of Chondrichthyes adds further support to our hypothesis that this widespread structural variant may represent an early-evolved and conserved form of GnRH. The presence of a GnRH molecular form in the plasma of the electric ray suggests that GnRH may reach target organs (pituitary and gonads) via the general circulation in some species of Chondrichthyes.
