Analysis of the Ush2a Gene in Medaka Fish (Oryzias latipes)
Patients suffering from Usher syndrome (USH) exhibit sensorineural hearing loss, retinitis pigmentosa (RP) and, in some cases, vestibular dysfunction. USH is the most common genetic disorder affecting hearing and vision and is included in a group of hereditary pathologies associated with defects in ciliary function known as ciliopathies. This syndrome is clinically classified into three types: ...
متن کاملBetanodavirus infection in the freshwater model fish medaka (Oryzias latipes).
Betanodaviruses, the causal agents of viral nervous necrosis in marine fish, have bipartite, positive-sense RNA genomes. As their genomes are the smallest and simplest among viruses, betanodaviruses have been studied in detail as model viruses by using a genetic-engineering system, as has occurred with the insect alphanodaviruses, the other members of the family Nodaviridae. However, studies of...
متن کاملAn Approach to Elucidate NBS1 Function in DNA Repair Using Frequent Nonsynonymous Polymorphism in Wild Medaka (Oryzias latipes) Populations
Nbs1 is one of the genes responsible for Nijmegen breakage syndrome, which is marked with high radiosensitivity. In human NBS1 (hNBS1), Q185E polymorphism is known as the factor to cancer risks, although its DSB repair defect has not been addressed. Here we investigated the genetic variations in medaka (Oryzias latipes) wild populations, and found 40 nonsynonymous single nucleotide polymorphism...
متن کاملStructural components of the synaptonemal complex, SYCP1 and SYCP3, in the medaka fish Oryzias latipes.
The synaptonemal complex (SC) is a meiosis-specific structure essential for synapsis of homologous chromosomes. For the first time in any non-mammalian vertebrates, we have isolated cDNA clones encoding two structural components of the SC, SYCP1 and SYCP3, in the medaka, and investigated their protein expression during gametogenesis. As in the case of mammals, medaka SYCP1 and SYCP3 are express...
متن کاملCytoplasmic Location of DNA Polymerase in Oocytes of the Teleost Fish, Oryzias latipes
The intracellular location of DNA polymerase α during oocyte maturation in the teleost fish Oryzias latipes was examined. In order to define the optimum assay conditions, DNA polymerase α from the ovaries of the fish was isolated and partially purified by column chromatography before it was characterized. Optimum conditions for the assay of DNA polymerase α activity were Tris-HCl(pH7.8)as a buf...
