Identification and characterization of two distinct GnRH receptor subtypes in a teleost, the medaka Oryzias latipes.
We report the identification and characterization of two distinct GnRH receptor (GnRH-R) subtypes, designated GnRH-R1 and GnRH-R2, in a model teleost, the medaka Oryzias latipes. These seven-transmembrane receptors of the medaka contain a cytoplasmic C-terminal tail, which has been found in all other nonmammalian GnRH-Rs cloned to date. The GnRH-R1 gene is composed of three exons separated by t...
متن کاملThe Genomic and Genetic Toolbox of the Teleost Medaka (Oryzias latipes)
The Japanese medaka, Oryzias latipes, is a vertebrate teleost model with a long history of genetic research. A number of unique features and established resources distinguish medaka from other vertebrate model systems. A large number of laboratory strains from different locations are available. Due to a high tolerance to inbreeding, many highly inbred strains have been established, thus providi...
متن کاملSex determination in fish: Lessons from the sex-determining gene of the teleost medaka, Oryzias latipes.
Although sex determination systems in animals are diverse, sex-determining genes have been identified only in mammals and some invertebrates. Recently, DMY (DM domain gene on the Y chromosome) has been found in the sex-determining region on the Y chromosome of the teleost medaka fish, Oryzias latipes. Functional and expression analyses of DMY show it to be the leading candidate for the male-det...
متن کاملOvarian Germline Stem Cells in the Teleost Fish, Medaka (Oryzias latipes)
In the mammalian testis germline stem cells keep producing many sperms, while there is no direct evidence for the presence of germline stem cells in the ovary. It is widely accepted in mammals that the mature oocytes are supplied from a pool of primordial follicles in the adult ovary. In other vertebrates, such as fish, however, there has been no investigation on the mechanism underlying the hi...
متن کاملTransgenic Medaka, Small Fresh Water Teleost (Oryzias latipes), is Now Available for Environmental Science
Recently, small model fish, medaka and zebrafish, have been casted a light on environmental science. Transgenic technique is a method that introduce exogenous gene into host genome and enables to generate unique model creature. Adapting transgenic technique on these fish, they become more powerful tool for evaluating aquatic contamination. Chemical analysis and in vitro bioassay, such as ELISA,...
