Research Abstract

Two recombinant eel gonadotropins (rGTH: rFSH-CTP and rLH-CTP) with long-lasting life were produced in mammalian cells. Administration of these rGTH could induce maturation of immature female eel. Furthermore, ovarian mass and expression of genes related to reproduction, induced by rFSH-CTP were significantly different from those by rLH-CTP, which indicates that two rGTH differentially act in the ovary of eel.
