Modulation of intestinal proteome of juvenile common carp (Cyprinus carpio L.) after dietary exposure to ZnO nanoparticles

ABSTRACT: ZnO nanoparticles (NPs) are widely used in industrial and consumer products. Thus, understanding their interaction with biological systems is the key for their safe application. The aim of present study was to evaluate the toxicological effects on the intestine of common carp, Cyprinus carpio, after dietary exposure to ZnO NPs. To assess the toxicity of ZnO NPs and of their toxic mechanism to gastrointestinal tract, we applied label free protein quantification on carp intestine considering the fact that fish are on the top of food chain in aquatic ecosystems. Even though carp and zebrafish do not have five intestinal segments like mammals (Brugman, 2016), previous studies have revealed that intestinal anatomy and architecture in cyprinid teleost fish is closely related to mammals with functional homology (Curry, 1939). Therefore, the findings can also provide beneficial information to understand the mechanisms underlying NPs toxicity in mammals.

ZnO nanoparticles (NPs) are widely used in industrial and consumer products. Therefore understanding their interaction with biological systems is key to their safe application. Proteomics was applied to assess the sub-lethal effects of dietary ZnO NPs on two parts of carp intestine, the intestinal folds and the muscular parts. A commercial carp feed containing 500mgkg<sup>-1</sup> of ZnO NPs was fed to fish for six weeks. The abundances of 32 proteins in the treated intestinal folds were signifi ...[more]

Project description:Parasite-mediated selection is considered one of the potential mechanisms contributing to the coexistence of asexual-sexual complexes. Gibel carp (Carassius gibelio), an invasive fish species in Europe, often forms populations composed of gynogenetic and sexual specimens. In the present study, experimental infection was induced in gynogenetic and sexual gibel carp using eye-fluke Diplostomum pseudospathaceum (Trematoda), and the transcriptome profile of the spleen as a major immune organ in fish was analyzed to reveal the differentially expressed immunity-associated genes related to D. pseudospathaceum infection differing between gynogenetic and sexual gibel carp. High parasite infection was found in gynogenetic fish when compared to genetically diverse sexuals. Although metacercariae of D. pseudospathaceum are situated in an immune-privileged organ, our results show that eye trematodes may induce a host immune response. We found differential gene expression induced by eye-fluke infection, with various impacts on gynogenetic and sexual hosts, documenting for the majority of DEGs upregulation in sexuals, and downregulation in asexuals. Differences in gene regulation between gynogenetic and sexual gibel carp were evidenced in many immunity-associated genes. GO analyses revealed the importance of genes assigned to the GO terms: immune function, the Notch signaling pathway, MAP kinase tyrosine/threonine/phosphatase activity, and chemokine receptor activity. KEGG analyses revealed the importance of the genes involved in 12 immunity-associated pathways – specifically, FoxO signaling, adipocytokine signaling, TGF-beta signaling, apoptosis, Notch signaling, C-type lectin receptor signaling, efferocytosis, intestinal immune network for IgA production, insulin signaling, virion - human immunodeficiency virus, Toll-like receptor signaling, and phosphatidylinositol signaling system. Our study indicates the limited potential of asexual fish to cope with higher parasite infection (likely a loss of capacity to induce an effective immune response) and highlights the important role of molecular mechanisms associated with immunity for the coexistence of gynogenetic and sexual gibel carp, potentially contributing to its invasiveness.
