Chlorpyrifos (CPF) is an environmental pollutant with increasing importance due to its high toxicity to fish and aquatic animals. To understand how CPF impacts immune response and oxidative stress in common carp (Cyprinus carpio L.), we investigated the transcriptomic profiles of the head kidneys from common carp exposed to CPF for 15days. A total of 52, 297, 928 and 52, 273, 784 high quality clean reads were obtained from CPF exposure groups, 44,677,578 and 44,106,696 high quality clean reads were obtained from corresponding control groups...

Rapid recruitment of small fish after biomanipulation in warm lakes may delay the reestablishment of submerged macrophytes, not least at high nutrient concentrations. Success has recently been obtained in controlling phosphorus (P) loading to many lakes, but nitrogen (N) inputs often remain high. To determine the interactive effects of N loading and the abundance of small-sized fish on the growth of the submerged macrophyte Vallisneria natans, we conducted an outdoor mesocosm experiment with a factorial design on the north shore of Lake Taihu, China...

In this study, two experiments were performed to explore the function of silymarin in adipogenesis in grass carp (Ctenopharyngodon idellus) using in vitro and in vivo models. In experiment 1, differentiated grass carp pre-adipocytes were treated with silymarin for 6 days. Treatment with 100 μg mL(-1)silymarin (SM100 group) significantly reduced triglyceride accumulation at day 6. The adipogenic gene expression levels of PPARγ, C/EBPα, SREBP1c, FAS, SCD1, and LPL, and the protein expression level of PPARγ were significantly down-regulated in the SM100 group...

It is commonly believed that hybridization might lead to the formation of new polyploidy species, but it is unclear whether hybridization can produce a new homodiploid species. Here, we report the spontaneous occurrence of a new crucian carp-like homodiploid fish (2n = 100) that originated from the interspecific hybridization of female common carp (Cyprinus carpio, Cyprininae, 2n = 100) × male blunt snout bream (Megalobrama amblycephala, Cultrinae, 2n = 48). The phenotype and reproductive traits of this new crucian carp-like homodiploid fish were found to be very similar to those of the existing diploid species (diploid crucian carp; Carassius auratus)...

It is well known that aluminium is the principle toxicant killing fish in acidified freshwater systems, and it has been shown that crucian carp (Carassius carassius) can survive exposures to aqueous aluminium levels toxic to most other freshwater fish species. The crucian carp has a remarkable ability to survive anoxic conditions, and the aim of the present study was to reveal if the tolerance to aluminium can be associated with the ability to survive prolonged anoxia. Crucian carps were exposed to either acidic Al-rich water (pH 5...

Glutamine synthetase (GS) is considered a master enzyme that catalyses ATP-dependent biosynthesis of glutamine from glutamate. In the present study, the GS gene was cloned from the intestine of grass carp, (Ctenopharyngodon idellus). The full-length cDNA sequence of GS encodes a 371-amino-acid polypetide. Phylogenetic analysis of the C. idellus GS sequence reveals common carp (Cyprinus carpio) as its closest neighbor. GS mRNA was differentially expressed in different tissues, with high to low gradient expression the intestine, brain, muscle, heart, gill, liver, pituitary gland, and spleen...

Bone morphogenetic proteins (Bmps) are a group of signaling molecules known to play important roles during formation and maintenance of various organs, not only bone, but also muscle, blood and so on. Common carp (Cyprinus carpio) is one of the most intensively studied fish due to its economic and environmental importance. Besides, common carp had encountered an additional round of whole genome duplication (WGD) compared with many closely related diploid teleost, which make it one of the most important models for genome evolutionary studies in teleost...

The present study was focused on the growth, body composition, metabolic abilities and innate immune responses in juvenile black carp Mylopharyngodon piceus fed with six levels of dietary leucine (7.3, 12.4, 16.2, 21.9, 28.3 and 34.5 g kg(-1)) for 9 weeks. Results showed that the highest weight gain (WG) and the lowest feed conversion ratio (FCR) was obtained at 23.5 and 23.9 g kg(-1) dietary leucine using second-order polynomial model, respectively. Adequate dietary leucine content (21.9 and 28.3 g kg(-1)) could significantly up-regulate the expression levels of neuropeptide Y (NPY) and ghrelin (GRL) in the brain of black carp juveniles...

Bacterins obtained from recombinant bacteria displaying heterologous antigens in its surface coded by prokaryotic rather than eukaryotic expression plasmids (here called "spiny" bacterins or spinycterins), have been used to increase fish immunogenicity of recombinant viral protein fragments. To explore their immunogenicity, five bacterial-specific membrane anchor-motifs characterized in the literature (Nmistic, Mistic, NTD, YAIN and YBEL) were genetically fused to the immunorelevant cystein-free 117 amino acid fragment II from the ORF149 of cyprinid herpes virus 3 (frgIICyHV3)...

As one of the most serious pathogens in the freshwater aquatic environment, spring viraemia of carp virus (SVCV) induces a high mortality rate in several cyprinid fishes. In this study, we designed and synthesized a total of 44 coumarin derivatives to evaluate the anti-SVCV activity. By comparing the inhibitory concentration at half-maximal activity (IC50), two imidazole coumarins (B4 and C2) were selected, with maximum inhibitory rates on SVCV more than 90%. Mechanistically, B4 or C2 did not affect viral adhesion and delivery from endosomes to the cytosol...

This study evaluated the protective effect of α-lipoic acid (LA) on n-3 highly unsaturated fatty acids (HUFAs)-induced lipid peroxidation in grass carp. The result indicated that diets with n-3 HUFAs increased the production of malondialdehyde (MDA) (P < 0.05), thereby inducing lipid peroxidation in liver and muscle of grass carp. Meanwhile, compared with control group, the hepatosomatic index (HSI) and kidney index (KI) of grass carp were markedly increased in n-3 HUFAs-only group. However, diets with LA remarkably inhibited the n-3 HUFAs-induced increase of HSI, KI, and MDA level in serum, liver and muscle (P < 0...

Muscle Ankyrin Repeat Proteins (MARPs) are a family of titin-associated stress response molecules and putative transducers of stretch-induced signalling in skeletal muscle. In cardiac muscle, Cardiac Ankyrin Repeat Protein (CARP) and Diabetes-Related Ankyrin Repeat Protein (DARP) reportedly redistribute from binding sites on titin to the nucleus following prolonged stretch. However, it is unclear whether Ankyrin repeat-domain protein2 (Ankrd2) shows comparable stretch-induced redistribution to the nucleus. We measured in rested human skeletal muscle 1) the absolute amount of MARPs, and 2) the distribution of Ankrd2 and DARP in both single fibers and whole muscle preparations...
