Interferon production was demonstrated by the goldfish-derived CAR cell line in response to infection by goldfish virus-2. Supernatants of infected cultures provided antiviral protection to CAR cells and another cell line derived from goldfish, ABIII. The protective factor retained activity after ultracentrifugation, dialysis, freezing and thawing, acid treatment (pH 2), or heating to 56 degree...
We have used the polymerase chain reaction to isolate cDNAs coding for goldfish and zebrafish neurolin, a previously identified 86 kDa cell surface glycoprotein in the goldfish visual system. Sequence analysis demonstrates that neurolin belongs to the immunoglobulin superfamily and is 51% similar to the chick cell adhesion molecule DM-GRASP, SC-1, BEN. Northern analysis with a riboprobe coding ...
Goldfish retinal ganglion cells (RGCs) can regrow their axons after optic nerve injury. However, the reason why goldfish RGCs can regenerate after nerve injury is largely unknown at the molecular level. To investigate regenerative properties of goldfish RGCs, we divided the RGC regeneration process into two components: (1) RGC survival, and (2) axonal elongation processes. To characterize the R...
A high-density linkage map of goldfish (Carassius auratus) was constructed using RNA-sequencing. This map consists of 50 linkage groups with 8,521 SNP markers and an average resolution of 0.62 cM. Approximately 84% of markers are in protein-coding genes orthologous to zebrafish proteins. We performed comparative genome analysis between zebrafish and medaka, common carp, grass carp, and goldfish...
Effects of representative mid-Michigan (USA) wastewater treatment plant (WWTP) effluents on the reproductive physiology of common goldfish (Carassius auratus) were assessed in situ by measuring plasma concentrations of vitellogenin (VTG), 17 beta-estradiol (E2), and testosterone (T), and evaluating gonad histology. Caged adult male and female goldfish were exposed for six weeks to WWTP effluent...
Twin-tail goldfish strains are examples of drastic morphological alterations that emerged through domestication. Although this mutation is known to be caused by deficiency of one of two duplicated chordin genes, it is unknown why equivalent mutations have not been observed in other domesticated fish species. Here, we compared the chordin gene morphant phenotypes of single-tail goldfish and comm...
Clear peaks of trematode Clinostomum complanatum cercariae detection rate in snails Radix auricularia japonica were observed around July a goldfish Carassius auratus farm Aichi Prefecture. Effects Trichlorfon and praziquantel examined against C. artificially infected goldfish. Both effective the early phase infection cohabitating with snails. Trichlorfon was 300 mg/t bath treatment for 13 d ...
goldfish carassius auratus were subjected to either formalin (250 ppm) or nacl (10 ppt), over a 0.5-h period followed by 24-h freshwater exposure. serum biochemistry was monitored before exposure (0), immediately after (0.5) plus 3 and 24 h after exposure. results showed that both formalin and nacl treatments caused rapid increase in cortisol with a peak at 3 h, which did not recover until 24 h...
This article describes a novel approach to study the metabolic regulation of the respiratory system in vertebrates that suits physiology lessons for undergraduate students. It consists of an experimental demonstration of the goldfish's (Carassius auratus) adaptations to anoxia. The goldfish is one of the few vertebrates showing strong enzymatic plasticity for the expression of alcohol dehydroge...
Nucleotide sequences for two immunoglobulin heavy chain variable region (VH) genes and one pseudogene in the goldfish (Carassius auratus) and the family relationships and distribution of these genes in individual fish are presented. Comparison of the nucleotide and inferred amino acid sequences of goldfish and other vertebrate VH genes indicates that goldfish VH genes show the major VH gene reg...
