Establishment of cell-lines stably expressing recombinant Japanese eel follicle-stimulating hormone and luteinizing hormone using CHO-DG44 cells: fully induced ovarian development at different modes
Autor: Yukinori Kazeto, Risa Ito, Toshiomi Tanaka, Hiroshi Suzuki, Yuichi Ozaki, Koichi Okuzawa, Koichiro Gen
Publikováno v: Frontiers in Endocrinology, Vol 14 (2023)
The gonadotropins (Gth), follicle-stimulating hormone (Fsh) and luteinizing hormone (Lh), play central roles in gametogenesis in vertebrates. However, available information on their differential actions in teleost, especially in vivo, is insufficient

Effect of GnRHa on plasma levels of Fsh and Lh in the female greater amberjack Seriola dumerili
Autor: Kazuhisa Hamada, Koichi Okuzawa, Yukinori Kazeto, Mitsuo Nyuji, Ikki Yamamoto
Publikováno v: Journal of Fish Biology. 95:1350-1354
The effects of gonadotropin-releasing hormone agonist (GnRHa) on plasma levels of follicle-stimulating hormone (Fsh) and luteinising hormone (Lh) are reported for female greater amberjack Seriola dumerili with post-vitellogenic ovarian oocytes. Five

Photoperiodic regulation of plasma gonadotropin levels in previtellogenic greater amberjack (Seriola dumerili)
Autor: Miyuki Mekuchi, Kazuhisa Hamada, Kiyoshi Soyano, Mitsuo Nyuji, Koichi Okuzawa, Yukinori Kazeto, Koichiro Gen
Publikováno v: General and Comparative Endocrinology. 269:149-155
In Seriola species, exposure to a long photoperiod regime is known to induce ovarian development. This study examined photoperiodic effects on pituitary gene expression and plasma levels of follicle-stimulating hormone (Fsh) and luteinizing hormone (

Development of a homologous radioimmunoassay for red seabream follicle stimulating hormone and regulation of gonadotropins by GnRH in red seabream, Pagrus major
Autor: Mitsuo Nyuji, Toshiya Yamaguchi, Yukinori Kazeto, Hideki Tanaka, Koichiro Gen, Susumu Uji, Koichi Okuzawa
Publikováno v: General and Comparative Endocrinology. 239:4-12
Using a recombinant chimeric single-chain follicle stimulating hormone (FSH), we established a radioimmunoassay (RIA) for red seabream (Pagrus major) FSH (pmFSH) which became a powerful tool for studying reproductive physiology. We studied the profil

Pelvic fin removal modifies escape trajectory in a teleost fish
Autor: Hideaki Yamada, Koichi Okuzawa, Taku Sato, Kimio Asami, Yuuki Kawabata, Masato Kobayashi
Publikováno v: Fisheries Science. 82:85-93
Pelvic fin removal has been used in mark-recapture studies and non-lethal tissue samplings; however, there is limited knowledge on the effect of fin removal on the locomotor performance in fish. We investigated the effect of pelvic fin removal on the
