Expression of Pejerrey Gonadotropin-Releasing Hormone in Three Orders of Fish
Molecular variants of GnRH were characterized by reverse-phase, high-performance liquid chromatography from brain extracts of fish in three different orders: Synbranchiformes (swamp eel [ Synbranchus marmoratus ]), Cyprinidontiformes (platyfish [ Xiphophorus maculatus ] and green swordtail [ X. hell...

description | Molecular variants of GnRH were characterized by reverse-phase, high-performance liquid chromatography from brain extracts
of fish in three different orders: Synbranchiformes (swamp eel [ Synbranchus marmoratus ]), Cyprinidontiformes (platyfish [ Xiphophorus maculatus ] and green swordtail [ X. helleri ]), and Atheriniformes (Patagonia pejerrey [ Odontesthes hatchery ]). Also, pituitary gland extracts from the pejerrey O. bonariensis (Atheriniformes) were characterized. Eluted fractions were tested in radioimmunoassays with antisera specific to GnRH, including
both antisera that detected only one form of GnRH and those that detected several forms. The results show that brain extracts
obtained from all species contained the same three molecular forms of GnRH, which were immunologically and chromatographically
undistinguishable from chicken GnRH-II, pejerrey GnRH (pjGnRH), and salmon GnRH. This study supports the hypothesis that expression
of these three forms is common in different fish orders and that pjGnRH is the main regulator of pituitary function in these
fish. |
