Thin-section studies of the sino-auricular border region in the hearts of 20 species of teleost fish revealed the cardiac internuncial cell (CIC), hitherto known only in Misgurnus, to occur also in 8 species (Acheilognathus lanceolatus, Carassius auratus longsdorffii, Cyprinus carpio, Girella punctata, Kareius bicoloratus, Rhodeus ocellatus ocellatus, Rhyncopelates oxyrhynchus, Tilapia nilotica...

The gene, vitellogenin (vtg) was cloned and characterized in the dojo loach (Misgurnus anguillicaudatus), an indigenous freshwater species in East Asia, in order to develop tools for detecting the effects of estrogenic endocrine-disrupting chemicals (EEDCs). Full-length cDNAs encoding seven distinct vtg transcripts (vtg1-7) were obtained. The corresponding deduced amino acid sequences (Vtg1-7) ...

Using a modified radiolabeled primer extension method (we named this modification misGvA-"misincorporation of G versus A") we have investigated the DNA synthesis and repair at early and late stages of development of loach Misgurnus fossilis. The misincorporation activity of DNA polymerase iota (Pol ι) in wild-type loach could not be detected by this method at any stage of loach development. In ...

Guizhou is an important ecological barrier in the upper reaches of Yangtze River and Pearl basins with abundant fish species. However, from these regions are threatened by anthropogenic activities, including overfishing habitat destruction. Here, we assessed diversity more than half species region using DNA barcoding (partial sequence cytochrome c oxidase subunit I (COI) gene). We obtained 800 ...
