Optimization of a protocol for fertilized egg production in Japanese eel using recombinant gonadotropins, LHRHa, pimozide, and 17α-hydroxyprogesterone
Autor: Hiroshi Suzuki, Toshiomi Tanaka, Koichiro Gen, Kazuharu Nomura, Yukinori Kazeto
Publikováno v: Aquaculture Reports, Vol 37, Iss , Pp 102270- (2024)
Recently, two types of Japanese eel recombinant gonadotropins (rGths), recombinant follicle-stimulating hormone (rFsh) and luteinizing hormone (rLh), have been successfully produced. However, the protocol for obtaining fertilized eggs using rGths has

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

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

Effects of rearing temperature manipulation on oocyte maturation progress in Japanese eel
Autor: Tatsuya Unuma, Kazuharu Nomura, Hideki Tanaka, Shinji Adachi, Toshiomi Tanaka
Publikováno v: Fisheries Science. 87:681-691
During the induction of Japanese eel maturation, administering maturation-inducing steroids (MIS) or their precursors at an inappropriate maturational status is a major cause of poor egg quality. In this study, we investigated the feasibility of cont

Maternal transcripts in good and poor quality eggs from Japanese eel, Anguilla japonica—their identification by large‐scale quantitative analysis
Autor: Seishi Hagihara, Koichiro Gen, Toshiomi Tanaka, Shigeho Ijiri, Shinji Adachi, P. Mark Lokman, Hikari Izumi, Moemi Horiuchi
Publikováno v: Molecular Reproduction and Development. 86(12):1846-1864
Our understanding of maternal control of development in vertebrates remains incomplete. In this study, we investigated levels of maternal transcripts in good and poor quality eggs from artificially matured Japanese eel, using RNA-Seq and quantitative

Publikováno v: Fisheries Science. 85:829-837
Two types of gonadotropins (Gths), follicle-stimulating hormone (Fsh) and luteinizing hormone (Lh), are primary regulators of reproduction in vertebrates, including teleost fish. In this study, recombinant Japanese eel Gths (reGth; reFsh and reLh), a

Fusion of lipid droplets in Japanese eel oocytes: Stage classification and its use as a biomarker for induction of final oocyte maturation and ovulation
Autor: Toshiomi Tanaka, Kazuharu Nomura, Tatsuya Unuma, Hideki Tanaka, Takahiro Matsubara, Sayumi Sawaguchi, Natsuki Hasegawa
Publikováno v: Aquaculture. :142-148
The quality of eggs obtained from maturation-induced Japanese eel, Anguilla japonica , is unstable. One of the causes for low quality eggs is that females are artificially induced to ovulate at an inappropriate maturational status. Here we investigat

Publikováno v: FEBS Journal. 278:3711-3723
We purified eel hatching enzyme (EHE) from the hatching liquid of Japanese eel Anguilla japonica belonging to Elopomorpha to a single band on SDS/PAGE. TOF-MS analysis revealed that the purified EHE contained several isozymes with similar molecular m

Publikováno v: Reviews in Fisheries Science. 16:228-234
We identified the optimal location for releasing hatchery-produced juveniles of ocellate puffer (Takifugu rubripes) for stock enhancement by tag and release experiments. The fish were released at four areas, Suruga Bay, Enshu Nada, Ise Bay, and Kuman
