Biology of the Japanese medaka Oryzias latipes and its culture for toxicological tests

In 1998, the Research Institute of Fish Culture and Hydrobiology at Vodňany has launched a breeding shoal of Japanese medaka (Oryzias latipes) strain bbRR for the embryotoxicological purpuses. Fish breed succesfully from Ma...

Ovarian structure protein 1: A sensitive molecular biomarker of gonadal intersex in female Japanese medaka after androgen exposure

Intersex in gonochoristic fish can be induced after exposure to androgens and estrogens. The main objective of the present study was to identify biomarkers that would be predictive of intersex in Japanese medaka (Oryzias latipes) af...

A lens-specific co-injection marker for medaka transgenesis

Recent advances in generating transgenic fish have improved the efficiency of germline transmission and enabled the generation of large numbers of transgenic animals. A suitable co-injection marker may help facilitate the preselection of tra...

Asymmetric pitx2 expression in medaka epithalamus is regulated by nodal signaling through an intronic enhancer

The epithalamic region of fishes shows prominent left-right asymmetries that are executed by nodal signaling upstream of the asymmetry-determining transcription factor pitx2. Previous reports have identified that nodal controls the left-side...

Differential retinoic acid sensitivity of oral and pharyngeal teeth in medaka (Oryzias latipes) supports the importance of pouch–cleft contacts in pharyngeal tooth initiation

Background: Previous studies have claimed that pharyngeal teeth in medaka in embryonic medaka, as it is in zebrafish. We used 4-[diethylamino]benzaldehyde (DEAB teeth in medaka were present only when the corresponding anter...

Genetic analysis of medaka fish illuminates conserved and divergent roles of Pax6 in vertebrate eye development

such as vertebrates. Here, to determine the functional role of the fish orthologue of mammalian Pax6 in eye development we analyzed mutants in medaka Pax6.1 gene generated lens tissue of Pax6.1 mutant fish resulting in aph...
