Project description:In previous study, we revealed that IRF10 is involved in the immune-reponse against bacteria and virus in Paralichthys olivaceus. However, the target genes of IRF10 is still unknown in teleosts. We searched the target genes of IRF10 by microarray in IRF10 over expressed HINAE cell HINAE cells were culured in 24-well plate. HINAE cells were transfected using lipofectamine2000 (Invitrogen, USA) with 7.2nM IRF10 expression plasmid vector (pcDNA3.1-IRF10) or empty-vector (pcDNA3.1). The equal volume of sterile water was used as a control. On other hands, the 1μg/ml of poly I:C also transfected to HINAE cells using lipofectamine2000 with each plasmid and vehicles (sterile water). After 48 hours from the transfection, we harvested the two samples of the control and poly I:C only and the three samples of plasmids or plasmids with poly I:C transfected cells (16 hybridization).

Project description:In this study, a high-throughput sequencing strategy was employed to identify the miRNAs involved in P. olivaceus albinism. High-throughput miRNA sequencing identified a total of 475 miRNAs, including 64 novel miRNAs. Furthermore, 33 differentially expressed miRNAs containing 13 up-regulated and 20 down-regulated miRNAs were identified in albino versus normally pigmented individuals (fold change ≥1.5 or ≤0.67 and p≤0.05).

Project description:In this study, a high-throughput sequencing strategy was employed to identify the mRNA involved in P. olivaceus albinism. Based on P. olivaceus genome, RNA-seq identified 21,787 know genes and 711 new genes by transcripts assembly. Of those, 235 genes exhibited significantly different expression pattern (fold change ≥2 or ≤0.5 and q-value≤0.05), including 194 down-regulated genes and 41 up-regulated genes in albino versus normally pigmented individuals. These genes were enriched to 81 GO terms and 9 KEGG pathways (p≤0.05). Among those, the pigmentation related pathways-Melanogenesis and tyrosine metabolism were contained.

Project description:After comparing albinism rate, T3 treatment and control larvae of 42 DAH were chosen for next high-throughput sequencing analyses of mRNA. RNA-seq identified 146 differentially expressed genes (DEGs) in D42_T3 versus D42_Con (|log2Foldchange| > 1 and q < 0.005), including pigmentation related genes such as the receptor tyrosine-protein kinase erbB-3, pro-opiomelanocortin A, melanotransferrin, and the growth-related gene somatotropin. These DEGs were significantly enriched to 15 GO terms and 8 KEGG pathways (q < 0.05), among which, several sugar metabolic pathways were included (glycolysis/gluconeogenesis and the pentose phosphate pathway).

Project description:The olive flounder (Paralichthys olivaceus) is an economically important flatfish in marine aquaculture with a broad thermal tolerance ranging from 14 to 23°C. Cold-tolerant flounder that can survive during the winter season at a temperature of less than 14°C might facilitate the understanding of the mechanisms underlying the response to cold stress. In this study, the transcriptional response of flounder to cold stress (0.7±0.05°C) was characterized using RNA sequencing. Transcriptome sequencing was performed using the Illumina MiSeq platform for the cold-tolerant (CT) group, which survived under the cold stress; the cold-sensitive (CS) group, which could barely survive at the low temperature; and control group, which was not subjected to cold treatment. In all, 29,021 unigenes were generated. Compared with the unigene expression profile of the control group, 410 unigenes were up-regulated and 255 unigenes were down-regulated in the CT group, whereas 593 unigenes were up-regulated and 289 unigenes were down-regulated in the CS group. Gene Ontology and Kyoto Encyclopedia of Genes and Genomes analyses revealed that signal transduction, lipid metabolism, digestive system, and signaling molecules and interaction were the most highly enriched pathways for the genes that were differentially expressed under cold stress. All these pathways could be assigned to the following four biological functions for flounder that can survive under cold stress: signal response to cold stress, cell repair/regeneration, energy production, and cell membrane construction and fluidity.

Project description:BACKGROUND: Japanese flounder (Paralichthys olivaceus) is one of the most economically important marine species in Northeast Asia. Information on genetic markers associated with quantitative trait loci (QTL) can be used in breeding programs to identify and select individuals carrying desired traits. Commercial production of Japanese flounder could be increased by developing disease-resistant fish and improving commercially important traits. Previous maps have been constructed with AFLP markers and a limited number of microsatellite markers. In this study, improved genetic linkage maps are presented. In contrast with previous studies, these maps were built mainly with a large number of codominant markers so they can potentially be used to analyze different families and populations. RESULTS: Sex-specific genetic linkage maps were constructed for the Japanese flounder including a total of 1,375 markers [1,268 microsatellites, 105 single nucleotide polymorphisms (SNPs) and two genes]; 1,167 markers are linked to the male map and 1,067 markers are linked to the female map. The lengths of the male and female maps are 1,147.7 cM and 833.8 cM, respectively. Based on estimations of map lengths, the female and male maps covered 79 and 82% of the genome, respectively. Recombination ratio in the new maps revealed F:M of 1:0.7. All linkage groups in the maps presented large differences in the location of sex-specific recombination hot-spots. CONCLUSIONS: The improved genetic linkage maps are very useful for QTL analyses and marker-assisted selection (MAS) breeding programs for economically important traits in Japanese flounder. In addition, SNP flanking sequences were blasted against Tetraodon nigroviridis (puffer fish) and Danio rerio (zebrafish), and synteny analysis has been carried out. The ability to detect synteny among species or genera based on homology analysis of SNP flanking sequences may provide opportunities to complement initial QTL experiments with candidate gene approaches from homologous chromosomal locations identified in related model organisms.

Project description:After comparing albinism rate, T3 treatment and control larvae of 42 DAH were chosen for next high-throughput sequencing analyses of miRNA. A total of 337 miRNAs were identified via miRNA-seq and 12 miRNAs exhibited significantly differential expression patterns in D42_T3 vs D42_Con (TPM > 10, fold change ≥ 1.5 or ≤ 0.67 and q ≤ 0.05). These differentially expressed miRNAs targeted 3658 putative genes, further enriching 10 GO terms (q < 0.05).

Project description:PRDM14 is a PR (PRDI-BF1-RIZ1 homologous) domain protein with six zinc fingers and essential roles in genome-wide epigenetic reprogramming. This protein is required for the establishment of germ cells and the maintenance of the embryonic stem cell ground state. In this study, we cloned the full-length cDNA and genomic DNA of the Paralichthys olivaceus prdm14 (Po-prdm14) gene and isolated the 5' regulatory region of Po-prdm14 by whole-genome sequencing. Peptide sequence alignment, gene structure analysis, and phylogenetic analysis revealed that Po-PRDM14 was homologous to mammalian PRDM14. Results of real-time quantitative polymerase chain reaction amplification (RT-qPCR) and in situ hybridization (ISH) in embryos demonstrated that Po-prdm14 was highly expressed between the morula and late gastrula stages, with its expression peaking in the early gastrula stage. Relatively low expression of Po-prdm14 was observed in the other developmental stages. ISH of gonadal tissues revealed that the transcripts were located in the nucleus of the oocytes in the ovaries but only in the spermatogonia and not the spermatocytes in the testes. We also presume that the Po-prdm14 transcription factor binding sites and their conserved binding region among vertebrates. The combined results suggest that Po-PRDM14 has a conserved function in teleosts and mammals.
