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.

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:In this study, three small RNA libraries constructed from gonad tissues of XX female, XY male and YY super-male yellow catfish were sequenced by Solexa high-throughput sequencing technology to investigate the expression pattern of sex-biased microRNA. The sequencing data generated a total of 384 conserved miRNAs and 113 potential novel miRNAs, among which 23, 30 and 14 miRNAs were specifically detected in XX ovary, XY testis, and YY testis, respectively. Interestingly, more abundant piRNAs were found in ovary compared to testis in yellow catfish, which phenomenon is also observed in other fish species but opposite in mammalians. We detected a number of microRNAs differentially expressed between ovary and testis, such as miR-21, miR-462, miR-430 and -200 family. When compared the transcriptome between XY and YY testis, we observed relative lower expression of miR-141 and miR-429 in YY testis. Histological analysis indicated that YY super-males have more spermatids and less spermatocytes in spermatogenic cyst than XY males under the same age and culturing conditions. The expression level of miR-141 and 429 coincides with the progression of spermatogenesis both in yellow catfish and human. At last, The expression pattern of nine arbitrarily selected miRNAs detected by quantitative RT-PCR was consistent with the Solexa sequencing results. Our study provides a comprehensive miRNA transcriptome analysis for gonad of yellow catfish with different sex genotypes, and identifies a number of sex-biased miRNAs that are potentially involved in sex differentiation and spermatogenesis.
