Project description:Common carp is one of the main commercial fishes captured and cultured worldwide. Although common carp genome is not finished yet, this study provides a first large scale cloning and characterization of common carp miRNAs and their potential targets. These miRNAs add to the growing database of new miRNA and lay the foundation for further understanding of miRNA function in gene regulation of common carp. We constructed a small RNA library from 17 Cyprinus carpio samples.

Project description:Purpose:In order to elucidate the molecular mechanism of the effects of different diets on the antioxidant capacity of fish, three groups of adult common carp (Cyprinus carpio) (initial weight 517.8 ±50 g) were fed with earthworm, earthworm + duckweed and duckweed, respectively, which were performed by miRNA sequencing. Methods:MiRNA profiles of common carp fed with earthworm, earthworm + duckweed and duckweed were generated by deep sequencing, in duplicate, using Illumina Hiseq 2500 platform. qRT–PCR validation was performed using SYBR Green assays Results: We built microRNA libraries by using total RNA and contained filtered 20,868,000, 18,984,242, 22,300,487, 19,538,683, 17,110,676 and 14,747,090 high-quality reads that were obtained from sample A1, A2, M1, M2, P1 and P2 respectively.In total, we discovered 236 known carp miRNAs (225, 225, 222, 227, 228 and 219 in A1, A2, M1, M2, P1and P2, respectively).For the known miRNA, 9 differentially expressed miRNAs (DEM) were found between A and M and 8 known miRNAs differentially expressed between P and M, and 11 of these were validated with qRT–PCR. The expression level of 11 known microRNAs via miRNA-seq had highly similar with the relative expression level of 11 known microRNAs via qRT-PCR. Conclusions: In present study, we demonstrated the transcriptional profiles, identification of 5 differentially expressed miRNAs be reported related to oxidative stress, including miR-137-3p, miR-143-3p, miR-146a-5p, miR-21-5p and miR-125b-5p. For omnivorous fish, feed a single bait may might cause oxidative stress inordinately.

Project description:purpose?To elucidate the relationship of utilization different type of diets in fish method?enzyme activity determination and transcriptome sequencing were performed in common carp fed with single animal diet group (group AD), plant diet group (group PD) and mix diets group (group MD). Group MD as control group results? 916 and 1296 differentially expressed genes were identified between group AD vs MD and PD vs MD. Protein digestion and absorption, bile secretion, hematopoietic cell lineage and intestinal immune network for IgA production pathways were significantly differentially expressed between common carp fed with single type of diet and mix diets. Conclusion?common carp fed with mix diets had stronger immunity than common carp fed with single type of diets.

Project description:Perfluorooctane sulfonate (PFOS) has been manufactured for over 50 years in increasing quantities and has been used for several industrial and commercial aims. Due to the persistence and the bioaccumulation of this pollutant, it can be found worldwide in wildlife and humans. Biochemical effects of PFOS exposure are mainly studied in mammalian model species and information about effects on fish species remain largely scarce. This lack of toxicity data points out that there is an urgent need for the mechanistic molecular understanding of the mode of action of this pollutant. In the present study, common carp (Cyprinus carpio) was exposed through water for 14 days at concentrations of 0.1; 0.5 and 1 mg/l PFOS. Liver was selected as target tissue. Custom microarrays were constructed from cDNA libraries obtained with Suppression Subtractive Hybridization-Polymerase chain reaction (SSH-PCR) experiments. Microarray data revealed that the expression of several genes in the liver was influenced by PFOS exposure and real-time PCR was used to confirm these gene expression changes. The affected genes were mainly involved in energy metabolism, reproduction and stress response. Furthermore, the relative condition factor and the hepatosomatic index of the exposed fish were significantly lower after 14 days of exposure as well as the available glycogen reserves. At all levels of biological organization, indications of a trade-off between the metabolic cost of toxicant exposure on one hand and processes vital to the survival of the organism on the other hand were seen. Our results support the prediction that increases in energy expenditure negatively affects processes vital to the survival of an organism, such as growth. Keywords: PFOS, common carp, microarray, condition factor, energy reserves, metabolic cost There were 3 biological replicates for each exposure concentration. For each biological replicate control versus exposed hybridizations were carried out. The mean of the biological replicates was calculated for the differentially expressed genes.

Project description:Genome-wide analysis of skin color-related lncRNA and mRNA expression in Koi carp, Cyprinus carpio L. LncRNAs information linked to fish skin color regulation is over-limited. In this study, Illumina sequencing and bioinformatics were primarily conducted on black, white and red skin colors of Koi carp. A total of 590,415,050 clean reads, 446,614 putative transcripts, 4,252 known and 72,907 novel lncRNAs were simultaneously obtained, respectively. Out of these genes, 92 significant differentially expressed lncRNAs and 722 mRNAs were excavated. Ccr_lnc5622441, Ccr_lnc765201 were found up-regulated in black and red skins; Ccr_lnc14074601 were up-regulated in white skin; and premelanosome proteins a (Pmela), tyrosinase (Tyr) were up-regulated in black skin, etc. Quantitative real-time PCR (qRT-PCR) further validated 12 differentially expressed genes were consistent with RNA-seq. Moreover, 70 lncRNAs on 107 target mRNAs in cis and 79 lncRNAs on 41,625 target mRNAs in trans were investigated, the networks revealed one lncRNAs can connected with numerous mRNAs, vice versa. These findings broadened the lncRNAs landscape of skin colors and provided new insights into the mechanisms underlying lncRNAs mediated pigmentation and differentiation in Koi carp.
