Hypoxia-inducible factors (HIFs) are transcription factors that respond to changes in oxygen tension in the cellular environment. In this study, we identified full-length cDNAs of HIF-1α, HIF-2α and HIF-3α in an endangered hypoxia-sensitive fish species, Chinese sucker. The HIF-1α/2α/3α cDNAs are 3890, 3230 and 3374 bp in length, encoding 780, 782 and 632(More)
Megalobrama amblycephala suffers from serious liver diseases recently and PPARα gene has been reported to play an important role in the immune system of animal liver. On the basis of these facts, we have cloned and identified full-length cDNA of PPARα and examined its expression patterns at different embryo developmental stages and in different tissues of(More)
Histone deacetylase 4 (HDAC4) is an important modifier enzyme for chromatin remodeling and plays an essential role in regulating gene expression. Spatio-temporal expression spectrum revealed that zebrafish hdac4 mRNA, ubiquitously distributed in various tissues, were significantly higher at 36 hpf (hours post-fertilization) and 6 dpf (days(More)
Eleven microsatellite markers were isolated and characterized from enriched genomic libraries of Channa argus. The loci were scored in 40 specimens from one natural population. We explored 6–17 alleles per locus with observed and expected heterozygosities ranging from 0.8000 to 1.0000 and 0.7269 to 0.9551, respectively, containing 0.830 average polymorphic(More)
We described the isolation and characterization of 15 new microsatellite loci from golden mandarin fish, Siniperca scherzeri. The analysis of variability was performed in 34 individuals. Allelic diversity ranged from 2 to 7 alleles per locus, with observed and expected heterozygosities ranging from 0.294 to 1.000 and 0.261 to 0.740, respectively. Seven loci(More)
Crayfish exoskeleton (CE) samples are generally less invasive and easy to be collected. However, it is difficult to extract DNA from them. This study was intended to investigate CE as a DNA source and design an easy and efficient DNA extraction protocol for polymerase chain reactions. Specific primer pair (PPO-F, PPO-R) was used to amplify extracted DNA(More)
The present study describes the detection of sheeppox virus antigen in various lamb tissues, using an immunohistochemical technique, in sheeppox cases which occurred naturally. Sheeppox viral antigen was detected in the cytoplasm of sheeppox cells and degenerated epithelial cells of the skin, lungs and digestive tract involving typical sheeppox lesions.(More)
PHD3 is a hydroxylase that hydroxylates prolyl residues on hypoxia-inducible factors (HIFs) in mammals. In this study, the full-length cDNA and promoter sequences of Megalobrama amblycephala PHD3 gene were isolated by a modified RACE method. PHD3 cDNA was 1622 bp in length, including an ORF of 717 bp encoding 238 amino acid residues. The semi-quantitative(More)
Immunoglobulins (Igs), which bind antigens with high specificity, are essential molecules in adaptive immune system of jawed vertebrates. In this study, cDNA encoding the secreted form of the immunoglobulin heavy chain of IgM (sIgM) was cloned from the mesonephros of blunt snout bream (Megalabrama amblycephala) using RT-PCR and rapid amplification of cDNA(More)
