Gene expression profiling at the single nuclei level of channel catfish spleen

ABSTRACT: Channel catfish, Ictalurus punctatus, is an important model U.S. aquaculutre species. Given its role in food production, the catfish immune response to industry-relevant pathogens has been extensively studied and has provided crucial information on innate and adaptive immune function during disease progression. To further examine the channel catfish immune system, single-nuclei RNA sequencing on whole spleens from three adult individuals was performed. Spleen cell suspensions were prepared by passing tissues through cell sieves. Single-cell RNAseq libraries were then prepared using the 10X Genomics Chromium X with the Next GEM Single Cell 3’ Reagents and sequenced 2x150bp on an Illumina sequencer. Each demultiplexed library was aligned to the CoCo_2.0 channel catfish reference assembly, filtered, and counted to generate feature-barcode matrices. Cluster analysis allowed for the identification of multiple cell types including erythrocytes, hematopoietic stem cells, B cells, T/NK cells, myeloid lineage derivatives, plasma cells and endothelial cells. The majority of cells detected were erythrocytes, which are nucleated in teleost fish.

Comparative transcriptomics of geographic strains of catfishes exposed to chronic high temperatures

Project description:This study examined differentially expressed (DE) gene transcripts and regulated pathways of two geographically distinct channel catfish (Ictalurus punctatus) strains and one hybrid catfish (I. punctatus x [blue catfish] I. furcatus) strain to test whether one particular catfish type handled thermal stress better. Following a six-week growth experiment, where fish were subjected to daily cycling temperatures of either 27-31M-BM-0C or 32-36M-BM-0C, mimicking pond fluctuations. We sequenced 18 cDNA libraries of liver samples to obtain 61 million reads per library. There were 5,443 DE transcripts and 41,689 regulated pathways. Northern channel catfish had the highest amount of DE transcripts (48.6%), 5 times that of southern channel catfish, and the greatest amount of transcripts with fold changes M-bM-^IM-% 2. The overall amount of temperature-induced DE transcripts between southern hybrid and southern channel catfish was fairly comparable in relation to that of northern channel catfish, however, there were more transcripts up- or downregulated with M-bM-^IM-% 2 fold changes in channel catfish strains compared to the southern hybrid catfish. Results from this study strongly suggest genetic differences between geographic catfish types affect physiological responses to thermal stress. Furthermore, a number of genes were linked to thermal stress tolerance, which may be beneficial for understanding geographic differences in thermal stress tolerance in ectotherms and for strain development of catfish.

Environmental dependent heterosis and transgressive gene expression in reciprocal hybrids between the channel catfish Ictalurus punctatus and the blue catfish Ictalurus furcatus

Project description:The hybrid between female channel catfish (Ictalurus punctatus) and male blue catfish (Ictalurus furcatus) is superior in feed conversion, disease resistance, carcass yield, and harvestability compared to both parental species. However, heterosis and heterobeltiosis only occur in pond culture, and channel catfish grow much faster than the other genetic types in small culture units. This environment-dependent heterosis is intriguing, but the underlying genetic mechanisms are not well understood. In this study, phenotypic characterization and transcriptomic analyses were performed in the channel catfish, blue catfish, and their reciprocal F1s reared in tanks. The results showed that the channel catfish is superior in growth-related morphometrics, presumably due to significantly lower innate immune function, as investigated by reduced lysozyme activity and alternative complement activity. RNA-seq analysis revealed that genes involved in fatty acid metabolism/transport are significantly upregulated in channel catfish compared to blue catfish and hybrids, which also contributes to the growth phenotype. Interestingly, hybrids have a 40-80% elevation in blood glucose than the parental species, which can be explained by a phenomenon called transgressive expression (overexpression/underexpression in F1s than the parental species). A total of 1,140 transgressive genes were identified in F1 hybrids, indicating that 8.5% of the transcriptome displayed transgressive expression. Transgressive genes upregulated in F1s are enriched for glycan degradation function, directly related to the increase in blood glucose level. This study is the first to explore molecular mechanisms of environment-dependent hetero-sis/heterobeltiosis in a vertebrate species and sheds light on the regulation and evolution of heterosis vs. hybrid incompatibility.

Comparative genomic analysis revealed twenty-six candidate genes involved in the air-breathing function of the broadhead catfish Clarias macrocephalus

Project description:Walking catfish (Clarias macrocephalus) and channel catfish (Ictalurus punctatus) are freshwater fish species of the Siluriformes order. C. macrocephalus has both gills and modified gill structures serving as an air breathing organ (ABO) which allows them aerial breathing (AB), while I. punctatus does not possess an air-breathing organ (ABO), and thus cannot breathe in air. These two species provide an excellent model for studying the molecular basis of accessory air-breathing organ development in teleost fish. In this study, seven development stages in C. macrocephalus were selected for RNA-seq analysis to compare with channel catfish as the time when air breathing organ developed and became functional. Through comparative genetic contents analysis, 1,458 genes were identified to be present in C. macrocephalus, but absent from I. punctatus. Gene expression analysis and protein-protein intersection (PPI) analysis were performed, 26 genes were selected in C. macrocephalus, including mb, ngb, hbae genes, which are mainly associated with oxygen carrier activity, oxygen binding and heme binding activities. Our work provides a large data resource for exploring the genomic basis of air breathing function in C. macrocephalus and offers an insight into the adaption of aquatic organisms to hypoxia and high ammonia environment.

Transcriptome Analysis of Tra Catfish (Pangasianodon hypophthalmus) Early Development Provides Novel Insights for the Terrestrial Adaptation

Project description:Channel catfish (Ictalurus punctatus) and tra catfish (Pangasianodon hypophthalmus) both belong to the order Siluriformes. Channel catfish does not possess an air-breathing organ (ABO), and thus cannot breathe in the air, while tra catfish is a facultative air-breather and use the swim bladder as its air-breathing organ, which provides for aerial breathing in low oxygen conditions. Tra and channel catfish serve as a great comparative model for studying the transition of life from water to terrestrial living, as well as for understanding genes that are crucial for development of the swim bladder and the function of air-breathing in tra catfish. We selected seven developmental stages in tra catfish for RNA-Seq analysis based on their transition to a stage that could live at 0 ppm oxygen. More than 587 million sequencing clean reads were generated in tra catfish, and a total of 21, 448 unique genes were detected. A comparative genomic analysis was conducted between channel catfish and tra catfish. Gene expression analysis was performed for these tra catfish specific genes. Hypoxia challenge and microtomy experiments collectively suggested that there are critical timepoints for the development of the air-breathing function and swim bladder development stages in tra catfish. Key genes were identified to be the best candidates of genes related to the air-breathing ability in tra catfish. This study provides a large data resource for functional genomic studies in air-breathing function in tra catfish, and sheds light on the adaption of aquatic organisms to the terrestrial environment.

Global gene expression analyses of channel catfish after being fed diets with inclusion of frass from black soldier fly larvae

Project description:Frass is the by-product of the larval meal industry and includes larval waste, exoskeleton sheds, and residual feed ingredients. Experimental frass was derived from the larvae of black solder flies (Hermetia illucens) fed distillers dried grains. A 10-week study was conducted to evaluate the effect of dietary levels of frass on the global gene expression of channel catfish, Ictalurus punctatus. Three diets containing 0, 50, and 300 g frass per kg diet were fed to channel catfish (5.24 ± 0.04 g) in quadruplicate aquaria to apparent satiation twice daily. Intestine (n=12 in pools of 3) and liver (n=12 in pools of 3) tissues were taken from fish at the end of the trial and processed for high-throughput Illumina RNA sequencing (RNAseq). Pairwise comparisons identified both up- and down-regulated genes in frass diets compared to no frass controls.

Global gene expression in catfish spleen after injection of lipopolysaccharide

Project description:A high-density oligonucleotide microarray for channel catfish (Ictalurus punctatus) was designed and produced with Maskless Array Synthesizer technology (MAS). The microarray contained ~379,652 24-mer oligonucleotides covering ~18,999 catfish unique sequences. The global expression profiling of the catfish spleens stimulated by lipopolysaccharide (LPS) for 2h, 4h, 8h and 24h was investigated with the microarray. In the spleen samples, 409 genes were identified to be induced or repressed greater than 2-fold by LPS treatment. Self-organizing maps (SOM) clustering analysis was applied to interpret gene expression patterns, and 84 of these genes were clustered into six expression patterns. Real-time RT-PCR was used to verify the microarray results for 9 selected genes representing different expression levels. The results from real-time RT-PCR were positively correlated (R^2 = 0.87) with the results from the microarray. Channel catfish were injected with LPS or PBS carrier. Fish were killed by anesthesia overdose at 2, 4, 8, or 24h post-injection and total RNA was isolated from spleen. The experiment contained two replicate fish per time point. Relative signal intensities for each feature were generated using the Robust Multi-Array Average algorithm and log2 transformed. Transformed data were then processed using quantile normalization, and the average and std. error for each gene were calculated from the 10 perfectly matched oligos only. After detransformation, the ratio (fold change) was calculated using PBS treated samples (control) as the baseline against LPS-treated samples.
