Project description:Heterosis is a complex biological phenomenon in which hybridization exhibit superior phenotypic characteristics. The underlying molecular basis for heterosis, particularly for fishes, remains elusive. In this study, we used next-generation sequencing technologies and tandem mass tags to characterise mRNA-seq, miRNA-seq and proteomic of Pelteobagrus fulvidraco, P. vachelli and hybrid yellow catfish Huangyou-1 (P. fulvidraco ♀×P. vachelli ♂) livers and in doing so, offer deeper insight into the transcriptional and protein changes in heterosis uncovers key roles for miRNAs.

Project description:The present NGST, TMT and Q-TOF MS platform should provide unprecedented resources to address such questions as to how hypoxic condition affects gene, miRNA, protein, and metabolite expression and changes the molecular pathways, and whether miRNAs participate in this process. For this purpose, we characterise transcriptomic, miRNAomic, proteomic and metabonomic sequencing of control- and hypoxia-treated P. vachelli muscles to elucidate the molecular mechanisms of hypoxia adaptation. We were able to find the predicted miRNA-mRNA-protein-metabolite regulatory network using bioinformatics analysis and miRNA prediction algorithms (Fig. 1). This is the first report on integrated analysis of transcriptome, miRNAome, and proteome, and metabolome in fishes and as such offers deeper insight into the hypoxia molecular mechanisms. We provide a good case study with which to analyse mRNA, miRNA, protein and metabolite expression and profile non-model fish species.

Project description:DEAD-box RNA-binding proteins (RBPs) play a significant role in RNA metabolism to achieve cellular homeostasis, including miRNA biogenesis and transcription. Hypoxia induces stemness cell-like characteristics in cancer cells and promotes malignant progression. Despite the fact that hypoxia can induce the changes in protein and RNA modification, thereby regulating downstream gene expressions, how modifications at different molecular layers interplay with each other are poorly understood. Here we show that hypoxia induces HectH9-mediated K63-linked polyubiquitination of the DEAD-box protein DDX17 as well as reduces N6-methyladenosine (m6A) marks in pri-miRNAs. While m6A potentiates DDX17 binding to pri-miRNAs, decreased m6A modifications of pri-miRNAs and increased polyubiquitination of DDX17 under hypoxia lead to decreased DDX17 binding to pri-miRNAs binding. These events enhance the association of DDX17 with the ubiquitin receptor p300 and lead to a decrease in miRNA biogenesis, especially for miRNAs regulating stemness and stemness-related genes. In addition, polyubiquitinated DDX17 together with p300 upregulates H3K56Ac levels on the stemness and stemness-related genes, resulting in enhancement of tumor initiating ability. Post-transcriptionally, decreased miRNA production, including those targeting stemness genes or stemness-related genes, also facilitates tumor initiation. Together, hypoxia triggers DDX17 poly-ubiquitination, which orchestrates dual mechanisms to increase tumor initiating ability and promote tumor progression.

Project description:Heterosis is a complex biological phenomenon in which hybridization exhibits superior phenotypic characteristics. The underlying molecular basis for heterosis, particularly for fishes, remains elusive. The utilization rate of fish heterosis far exceeds our understanding of it on a theoretical level. To gain a comprehensive and unbiased molecular understanding of fish heterosis, we characterized mRNA-seq, miRNA-seq, and proteomes of Pelteobagrus fulvidraco, P. vachelli, and the hybrid yellow catfish Huangyou-1 (P. fulvidraco ♀×P. vachelli ♂) livers using next-generation sequencing technologies and tandem mass tags. Our results show that the nonadditive, homoeologue expression bias and expression level dominance pattern were readily identified in transcriptional, post-transcriptional, or protein levels, providing the evidence for the widespread presence of dominant models during hybridization. At the same time, a number of miRNA-mRNA-protein pairs were found and validated by qRT-PCR and parallel reaction monitoring assays.

Project description:Background: Yellow catfish (Pelteobagrus fulvidraco) is one of the important aquaculture species in China. In recent years, due to the high breeding density, the increasing frequency of feeding, and the excessive addition of feed fat, the excessive deposition of body fat in cultured yellow catfish has become more frequent. MicroRNAs (miRNAs) are an important gene expression regulatory signal molecule that regulates liver fat synthesis and transport and play an important role in fat deposition. However, there is a little research on the mechanism of fatty liver caused by excessive deposition of liver fat. Results: After 60 days of high-fat stress, the growth and feed conversion rate of hybrid yellow catfish (Pelteobagrus fuIvidraco♀×P. vachelli♂) were significantly inhibited, and hepatosomatic index, viscerosomatic index, hepatic triglyceride and cholesterol, and red lipid droplets in liver tissues were increased. Through high-throughput sequencing, we constructed miRNA libraries of high-fat stress at 60d, identified 346 conserved miRNAs and 410 novel miRNAs, among which 13 differentially expressed miRNAs were screened between high-fat diet group and normal-fat diet group. Also, we constructed mRNA transcriptome libraries after high-fat stress. Potential target genes for differentially expressed miRNAs were identified by bioinformatics analysis. Seven miRNA-mRNA pairs were screened. The expression of differential miRNA and mRNA and potential binding sites were analyzed by qRT-PCR and dual luciferase assay. Hybrid yellow catfish could promote the oxidative degradation of liver glucose, reduce fatty acid peroxidation, regulate antioxidant enzyme activity and response of immune and inflammatory to relieve fat deposition and liver stress. Conclusions: The disorders of fat metabolism in liver not only result in feed wastage, increase metabolic burden of yellow catfish, but also cause immune function damage, resulting in a variety of nutritional diseases. The development of this study is to understand the molecular mechanism of hepatic fat deposition in yellow catfish. It has important biological significance for improving protection of liver against stress and healthy culture.
