    • The invention provides recombinant forms of piscine follicle-stimulating hormone (FSH) with characteristic intramolecular disulfide bonds and modified glycosylation patterns in the β-subunit that enhance the stability and metabolic activity of the hormone. Also provided are recombinant materials to produce the FSH β and glycoprotein α-subunits singly or in combination to obtain complete heterodimeric hormone of regulated glycosylation pattern. The piscine FSH agonists of the invention are therapeutically useful to expedite the onset of puberty in captive fish and to alleviate reproductive dysfunctions in fish. Likewise, the piscine FSH antagonists of the invention will be therapeutically useful to halt gonadal development, thereby contributing to body weight gain of the fish.
    • 本发明提供了具有特征性分子内二硫键的鱼类促卵泡激素(FSH)的重组形式,并且在β亚单位中改进了糖基化模式,其增强了激素的稳定性和代谢活性。 还提供了单独或组合产生FSHβ和糖蛋白a-亚基的重组材料,以获得调节的糖基化模式的完全异二聚体激素。 本发明的鱼类FSH激动剂在治疗上有助于加速捕获鱼中青春期的发病并减轻鱼中的生殖功能障碍。 同样地,本发明的鱼FSH拮抗剂在治疗性腺炎发展方面是有用的,从而有助于鱼的体重增加。
