Project description:Two-condition experiment, Wild-type biofilm cells vs. smcR mutant biofilm cells. Biological replicates: 3 control, 3 mutant strains, independently grown and harvested. One replicate per array. A significant portion of the SmcR regulon predicted on the basis of microarray analysis results is indeed regulated by SmcR and that SmcR functions on biofilm dispersion in V. vulnificus. For transcriptome analysis, the V. vulnificus whole genome TwinChip, manufactured by e-biogen (Seoul, South Korea), was used.
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:Sequencing of 16S ribosomal RNA (rRNA) gene, which has improved the characterization of microbial community, has made it possible to detect a low level Helicobacter pylori (HP) sequences even in HP-negative subjects which were determined by a combination of conventional methods. This study was conducted to obtain a cutoff value for HP colonization in gastric mucosa biopsies and gastric juices by the pyrosequencing method.

Project description:Anim Genet. 2009 Feb;40(1):115-8. Epub 2008 Oct 17. Differentially expressed transcripts in adipose tissue between Korean native pig and Yorkshire breeds. Moon JK, Kim KS, Kim JJ, Choi BH, Cho BW, Kim TH, Lee CK. Division of Biotechnology, College of Life Sciences & Biotechnology, Korea University, Seoul, South Korea. We measured and compared the transcripts of adipose tissue from Korean native pig (KNP) and Yorkshire (YS) breeds to investigate breed-specific transcription changes. We employed both the Affymetrix porcine genome array and quantitative reverse transcription-polymerase chain reaction (qRT-PCR). We found eight genes showing significant changes between the two breeds. Based on a literature review, these genes were indicative of differences in extracellular structure density and differences in the potential to metabolize xenobiotic chemicals and lipids. The differentially expressed genes indicated that KNP has a lower extracellular structure density and a lower potential to metabolize xenobiotic chemicals than YS. PMID: 18945290

Microbial DNA from gastric mucosal samples [gastric antrum (n=63, mucosal biopsy), follow-up sample on gastric antrum (n=16, mucosal biopsy), and gastric body (n=18, mucosal biopsy)] and gastric juices (n=4, not mucosal biopsy) was amplified by nested PCR using universal bacterial primers, and the 16S rRNA genes were pyrosequenced.
