Combined analysis of transcriptome and metabolome in tilapia (GIFT, Oreochromis niloticus) exposed to acute hypoxia stress

Project description:Dissolved oxygen (DO) in cultured water is one of the important environment factor in fish farming. Hypoxic environment affects fish growth, metabolism and immune system. Multi-omics integrative analysis helps to uncover the underlying molecular mechanisms. In this study, the 96h median lethal hypoxia (96h-LH50) for Genetically Improved Farmed Tilapia (GIFT, Oreochromis niloticus) was first analyzed by linear interpolation. We built control (5mg/l) and hypoxic stress (96h-LH50) groups, and extracted the liver tissues for high-throughput transcriptome and metabolome sequencing. The identification and quantification results of metabolites showed that a total of 19656 metabolites had been obtained, of which 10390 were annotated. There were 3028 differentially expressed (DE) metabolites, of which 1596 metabolites were up-regulated and 1432 metabolites were down-regulated. We obtained 2375 DE genes, of which 1201 genes were up-regulated and 1174 genes were down-regulated. We verified 8 DE genes by quantitative real-time PCR. Our finding reveals the changes in metabolites and genes expression of GIFT and facilitate the understanding of regulatory pathways under hypoxic stress, which will help reduce the damage caused by hypoxic stress during culture.

Nile tilapia (Oreochromis niloticus) gene expression profiling in males and females at early embryonic development (2, 5 and 9 days post fertilization )

Project description:Commercial production of tilapia relies on monosex cultures of males, which so far proved difficult to maintain in large scale production facilities. Thus, a better understanding of the genetic architecture of the complex trait of sex determination in tilapia is needed.We aimed to detect genes that were differentially expressed by gender at early embryonic development. Artificial fertilization of O. niloticus females with either sex-reversed males (ΔXX) or genetically-modified YY 'supermales' resulted in all-female and all-male embryos, respectively. Pools of all-female and all-male embryos at 2, 5 and 9 days post fertilization were used for custom Agilent eArray. 56 pool samples of Nile tilapia full siblings groups (female or male) at day 2, 5 or 9 post fertilization were subjected to total RNA extraction from whole embryo tissues and hybridized to the custom Agilent array. Each sample was yielded from different cross of artificial fertilization: six dams X five sires. The resulting gender were known based on the sire, sex-reversed males (ΔXX) or genetically-modified YY 'supermales' resulted in all-female and all-male embryos, respectively.

Total RNA sequencing of the liver tissues of Oreochromis niloticus (Nile Tilapia) and of Pundamilia nyerei

Project description:Cichlids fishes exhibit extensive phenotypic diversification and speciation. In this study we integrate transcriptomic and proteomic signatures from two cichlids species, identify novel open reading frames (nORFs) and perform evolutionary analysis on these nORF regions. We embark comparative transrcriptomics and proteogenomic analysis of two metabolically active tissues, the testes and liver, of two cichlid species Oreochromis niloticus (Nile tilapia, ON) and Pundamilia nyererei (Makobe Island, PN). Our results suggest that the time scale of speciation of the two species can be better explained by the evolutionary divergence of these nORF genomic regions.

Growth, blood biochemistry, histology and transcriptomic profile analysis influences liver fat deposition and inflammation process following dietary supplementation of apple peel powder in Genetically Improved Farmed Tilapia (GIFT, Oreochromis niloticus)

Project description:GIFT is a type of freshwater farmed fish with high economic value and nutritional value. The liver is an important organ of fish metabolism. Once it is damaged or the disease occurs, it will lead to metabolic disorders and decreased disease resistance, and may cause other secondary diseases. In the high-density intensive culture of tilapia, the feed nutrition is not balanced, especially the addition of high-fat feed. High fat content can accelerate the growth of fish, but long-term feeding of high-fat diet can lead to metabolic disorders of fish, accumulation of fat in the body, easy to cause fatty liver, and ultimately death due to liver necrosis or hemorrhage, seriously affecting the breeding benefits. The main purpose of this study was to investigate the effects of apple peel added to feed on liver fat metabolism and fat deposition in tilapia tilapia; use transcriptomics to analyze related signal regulation pathways, focusing on fat metabolism and inflammatory response; and finally screening differentially expressed genes. The development of this study is helpful to understand the molecular mechanism of apple peel extract powder-mediated liver fat metabolism and inflammatory response in GIFT, and relieve liver stress. It also provides theoretical support for the application of apple peel extract powder as a feed additiion in aquatic products.

Metacercarial infection of wild Nile tilapia (Oreochromis niloticus) from Brazil.

Project description:Fingerlings of Oreochromis niloticus collected in an artificial urban lake from Belo Horizonte, Minas Gerais, Brazil, were evaluated for natural infection with trematodes. Morphological taxonomic identification of four fluke species was performed in O. niloticus examined, and the total prevalence of metacercariae was 60.7% (37/61). Centrocestus formosanus, a heterophyid found in the gills, was the species with the highest prevalence and mean intensity of infection (31.1% and 3.42 (1-42), resp.), followed by the diplostomid Austrodiplostomum compactum (29.5% and 1.27 (1-2)) recovered from the eyes. Metacercariae of Drepanocephalus sp. and Ribeiroia sp., both found in the oral cavity of the fish, were verified at low prevalences (8.2% and 1.6%, resp.) and intensities of infection (only one metacercaria of each of these species per fish). These species of trematodes are reported for the first time in O. niloticus from South America. The potential of occurrence of these parasites in tilapia farming and the control strategies are briefly discussed.
