Project description:In order to identify gene expression difference between marine and freshwater stickleback populations, we compared the transcriptomes of seven adult tissues (eye, gill, heart, hypothalumus, liver, pectoral muscle, telencephalon) between a marine population sampled from the mouth of the Little Campbell river in British Columbia (LITC) and a freshwater population (Fishtrap Creek, FTC) from northern Washington. For each population, the sampled individuals were the lab-reared progeny of a single pair of wild-caught parents. Four to five fish from each population were used as biological replicates for each of the seven tissues. For each population, the sampled individuals were the lab-reared progeny of a single pair of wild-caught parents. All fish were of similar age and were raised in the same aquarium (salinity: 3.5 ppt), with a plastic divider separating the marine and freshwater groups. One male and four females were sampled from each population. Microarray experiments were performed in a 2-color format on custom Agilent arrays: experimental RNA samples were labeled with Cy5, and the common reference RNA sample was labeled with Cy3. The reference RNA was total RNA isolated from a large number of 7-day-post-hatch embryos from the freshwater population of Bear Paw Lake, Alaska (BEPA). One technical replicate was used for each array, and one of the hypothalamus samples (Hyp_FTC#3) was excluded from further analysis due to poor quality indicators. FTC#1 liver and LITC#2 pectoral muscle samples did not yield RNA of sufficient quality for the microarray experiment, and were also excluded from hybridization.

Project description:RNA from PCB-126 exposed 10 days post-fertilization (dpf) embryos were sequenced to characterize the chemical exposure response of killifish from a PCB-resistant population (NBH, New Bedford Harbor, MA, Superfund site) as compared to a reference (SC, Scorton Creek, MA) population. Since the genome sequence was not available, we also performed shot-gun sequencing of RNA from 1-15 dpf embryos sampled every day from both populations to serve as a transcriptome assembly. The results suggest that the NBH fish possess a gene regulatory defect that is not limited to a few target genes. We detected multiple genes that were differentially expressed in these two populations. This study was the first application of pyrosequencing technology to combine transcriptome characterization and gene expression profiling in a marine animal.

Project description:We report the application of Solexa/IlluminaM-bM-^@M-^Ys RNA-seq sequencing approaches for transcriptome in a marine fish under different conditions (bacterial- and mock-challenged conditions). By obtaining over four billion bases of sequence from the cDNA, we generated 169,950 none-redundant consensus sequences, from which 44842 functional transcripts with complete or various length of encoding regions were identified. More than 52% of these transcripts could be enriched in approximately 219 known metabolic or signaling pathways, among of which 2673 transcripts were found to be associated with immune-relevant genes. Besides, about 8% of the transcripts seemed fish-specific genes that have never been described before. This study provides a framework for the application of comprehensive chromatin profiling towards characterization of diverse mammalian cell populations. Our study provided a global survey of the gene activities in host defense against bacterial infection in a non-model marine fish. Examination of different transcriptome in baterial- and mock challenged fish.
