A two-receptor model for salmon gonadotropins (GTH I and GTH II).
TL;DR: A two-receptor model for the postvitellogenic/preovulatory salmon ovary is proposed with the following features: there are two types of gonadotropin receptors in the salmon Ovary, type I and type II; and the type I receptor binds both GTHs, but with higher affinity for GTH I, whereas the type II receptor is highly specific for G TH II and may have only limited interaction with G TH I.

Changes in plasma vitellogenin, sex steroids, calcitonin, and thyroid hormones related to sexual maturation in female brown trout (Salmo trutta).

TL;DR: Female brown trout from a wild strain and a cultured strain were sampled individually for blood plasma at regular intervals during the period around final sexual maturation, finding discrepancies observed between wild and cultured females may be due to differences in stress susceptibility, environmental conditions, life cycles, or to genetic divergence between the strains.

Gonadotropin and Activin Enhance Maturational Competence of Oocytes in the Zebrafish (Danio rerio)
Yefei Pang,Wei Ge +1 more
TL;DR: Pretreatment of follicles with gonadotropin (hCG) significantly enhanced the responsiveness of midvitellogenic oocytes to DHP in a clear time- and dose-dependent manner, and activin, an ovarian growth factor, also had a potent stimulatory effect on the acquisition of oocyte maturational competence.

Cloning, Functional Characterization, and Expression of a Gonadotropin Receptor cDNA in the Ovary and Testis of Amago Salmon (Oncorhynchus rhodurus)
Yuichi Oba,Toshiaki Hirai,Yasutoshi Yoshiura,Michiyasu Yoshikuni,Hiroshi Kawauchi,Yoshitaka Nagahama +5 more
TL;DR: Results indicate that the cloned cDNA encodes a functional amago salmon GTH receptor protein, which belongs to the glycoprotein hormone receptor family with a large extracellular and seven-transmembrane domains.
