저장배에서 분리한 15그룹 3종을 KCTC, KCCM, 충남대에서 분양받은 16균주를 대상으로 상호 유연관계를 분석하고자 배양적 특성을 관찰하고 RAPD 검정에 의한 진단 가능성을 검토하였다. 병원균의 배양특성을 조사한 결과 배지상 생육형태, 색, 속도 등에 있어서 균주간 차이를 보였으며 배양적 특성과 RAPD에 의한 유연관계 분석 결과를 비교 분석하기 위하여 배에서 분리한 15개 균주와 16개 표준 균주의 종간 다형성을 관찰하였다. RAPD을 이용하여 유전적 다양성을 분석하기 위하여 5개의 URP primer를 이용하여 genomic DNA를 증폭시킨 결과 $0.1{\sim}2.0kb$ 크기의 총 744개 band들이 증폭되었다. cluster 분석결과 전체 유사도는 47.7%로 31 균주들은 4개의 genomic DNA RAPD 집단으로 분류되었다. 배에서 분리한 P. expansum 균주간에는 87.4% 이상의 상동성을 보였고, P. solitum 균주간에는 97.5%, P. crustosum 균주 간에는 95.1% 이상의 상동성을 보였다. 배에서 분리된 동일한 종내에서는 배양적 특성에 의한 동정결과와 RAPD에 의한 분석결과와 일치하였다.

Activation of Toll-like receptor-4 (TLR-4) in articular chondrocytes increases the catabolic compartment and leads to matrix degradation during the development of osteoarthritis. In this study, we determined the proteomic and genomic alterations in human chondrocytes during lipopolysaccharide (LPS)-induced inflammation to elucidate the underlying mechanisms and consequences of TLR-4 activation. Human chondrocytes were cultured with LPS for 12, 24, and 36 h to induce TLR-4 activation. The TLR-4-induced inflammatory response was confirmed by real-time PCR analysis of increased interleukin-1 beta ($IL-1{\beta}$), interleukin-6 (IL-6), and tumor necrosis factor alpha ($TNF-{\alpha}$) expression levels. In TLR-4-activated chondrocytes, proteomic changes were determined by two-dimensional electrophoresis and matrix-assisted laser desorption/ionization-mass spectroscopy analysis, and genomic changes were determined by microarray and gene ontology analyses. Proteomics analysis identified 26 proteins with significantly altered expression levels; these proteins were related to the cytoskeleton and oxidative stress responses. Gene ontology analysis indicated that LPS treatment altered specific functional pathways including 'chemotaxis', 'hematopoietic organ development', 'positive regulation of cell proliferation', and 'regulation of cytokine biosynthetic process'. Nine of the 26 identified proteins displayed the same increased expression patterns in both proteomics and genomics analyses. Western blot analysis confirmed the LPS-induced increases in expression levels of lamin A/C and annexins 4/5/6. In conclusion, this study identified the time-dependent genomic, proteomic, and functional pathway alterations that occur in chondrocytes during LPS-induced TLR-4 activation. These results provide valuable new insights into the underlying mechanisms that control the development and progression of osteoarthritis.

Despite its economic importance as an aquaculture species, the molecular and genetic information regarding physiologically important elements in rock bream (Oplegnathus fasciatus) is not completely understood. Rab proteins play a vital role in cellular mechanisms and immunity as one of the key regulators of membrane trafficking. In this investigation, a Rab gene, named as RbRab-5C-like, was identified from Oplegnathus fasciatus. RbRab-5C-like protein exhibited high homology with Rab proteins of other species and possessed signature characteristics of Rab proteins with four conserved cysteine residues. Phylogenetic analysis showed that RbRab-5C-like clustered with other fish counterparts. The RbRab-5C-like genomic sequence possesses six exons and five introns. Transcriptional analysis revealed that RbRab-5C-like was ubiquitously expressed in all examined tissues with the highest expression occurring in the liver. While the structural and homologic characteristics of RbRab-5C-like suggest a strong conservation of this element in different species, its mRNA distribution implies a wide range of biological significance in rock bream.

A visual analysis approach and the developed supporting technology provide a comprehensive solution for analyzing large and complex integrated genomic and biomedical data. This paper presents a methodology that is implemented as an interactive visual analysis technology for extracting knowledge from complex genetic and clinical data and then visualizing it in a meaningful and interpretable way. By synergizing the domain knowledge into development and analysis processes, we have developed a comprehensive tool that supports a seamless patient-to-patient analysis, from an overview of the patient population in the similarity space to the detailed views of genes. The system consists of multiple components enabling the complete analysis process, including data mining, interactive visualization, analytical views, and gene comparison. We demonstrate our approach with medical scientists on a case study of childhood cancer patients on how they use the tool to confirm existing hypotheses and to discover new scientific insights.

사람에게서 유래된 DNA시료의 X,Y 특이의 alphoid gene을 PCR법으로 분석하면 성별을 확인할 수 가 있다. PCR법으로 alphoid gene을 분석한바 매우 예민도가 높아 genomic DNA 약 60pg까지 성별을 분석할 수 있었다. 그리고 성별이 혼합되어 있는 DNA에서 female DNA의 1/10비 까지는 male DNA를 분석할 수 있었다. 따라서 이 결과는 혼합된 DNA에서 X,Y 특이의 alphoid gene을 분석하는데 기준으로 활용할 수가 있다.
