Project description:Spirosoma montaniterrae DY10T is an uncharacterized radiation-resistanct bacteria isolated from soil in South Korea. In order to identify the underlying mechanisms involved in UVC-resistance, we generated time-series transcriptome data with UVC radiation and analyzed data with computational methods.
Project description:The gut of chicken is mostly colonised with Campylobacter jejuni and with 100 fold less C. coli. The competitive ability of C. coli OR12 over C. jejuni OR1 has been examined in experimental broiler chickens following the observation that C. coli replaced an established C. jejuni intestinal colonisation within commercial chicken flocks reared outdoors (El-Shibiny, A., Connerton, P.L., Connerton, I.F., 2005. Enumeration and diversity of campylobacters and bacteriophages isolated during the rearing cycles of free-range and organic chickens. Applied Environmental Microbiology. 71, 1259-1266).
Project description:Agelena koreana is indigenous spider in South Korea that lives on piles of trees building webs. RNA-sequencing was performed for venom gland tissue and whole body except venom gland.
Project description:Purpose: to identify how condensin I removal affects gene expression globally. Methods: Chicken DT40 CAP-H KO cells were treated with or without dox for 36 h. Total RNA samples were extracted and subjected to sequencing using an Illumina Hiseq2000 platform. Library preparation and Illumina sequencing were performed by Macrogen (South Korea). The sequence tags were spliced-mapped onto the chicken genome galGal4 using Tophat and Bowtie2 following quality test using FASTQC. Differential expression of genes was analyzed using the Bioconductor v2.3 package edgeR v3.2.3. Tag enrichment in NCBI RefSeq genes was calculated between dox-treated and untreated cells using edgeR exact test with tag-wise dispersion estimation. Results: We identified a total of 3798 genes to be differentially expressed in G1 condensin I-depleted chicken DT40 cells: 2495 down regulated and 1303 up regulated. Conclusions: Removal of CAP-H leads to significant misregulation of gene expression, suggesting a key role for condensin I in transcription during interphase.

Project description:Castellaniella spp. isolated from chicken
Project description:Campylobacter jejuni is a human pathogen which causes campylobacteriosis, one of the most widespread zoonotic enteric diseases worldwide. Most cases of sporadic C. jejuni infection occur through the handling or consumption of undercooked chicken meat, or cross-contamination of other foods with raw poultry fluid. A common practice to combat Campylobacter infection is to treat chickens with chlorine which kills the microbe. This analysis aimed to elucidate the transcriptomic response of Campylobacter jejuni treated with hypochlorite through Illumina sequencing. C. jejuni was grown and treated with hypochlorite. Samples were taken 5, 20 and 45 min after treatment for RNAseq analysis.The data generated were compared to the transcriptome pre-exposure to determine C. jejuni's response to hypochlorite.

Total RNA profiles of CAP-H KO cells with or without Dox were generated by sequencing using Illumina Hiseq2000 platform.
