Systems biological analysis of immunity to dengue
  • organism-icon Homo sapiens
  • sample-icon 55 Downloadable Samples
  • Technology Badge Icon Affymetrix HT HG-U133+ PM Array Plate (hthgu133pluspm)

Description

Dengue virus (DENV) infects hundreds of millions of people annually, yet there is only a limited knowledge of the host immune response to dengue. Here, we used a systems biological approach to perform a detailed analysis of the innate immune response to DENV infection in the whole blood samples of acutely infected humans in Bangkok, Thailand. Transcriptomic analysis revealed that genes encoding pro-inflammatory mediators and type I IFN related proteins, were associated with high levels of virus during the first few days of infection. Individuals with low or negative viremia at the late stage of fever were enriched with genes associated with pathways involved in cell cycle, proliferation, cell metabolism and translational control. Meta-analysis showed significant enrichment in genes specific for innate cells (monocytes, macrophages and DCs) in the specimens with high VL and enrichment in genes specific for NK cells, CD4+ and CD8+ T cells as well as B cells in specimens with low VL. Furthermore, flow cytometric analysis revealed an expansion in the numbers of CD14+CD16+ monocytes and depletion of CD14dimCD16++ cells and BDCA-1+ myeloid DC in blood. Consistent with this, in a non-human primate model, infection with DENV boosted the numbers of CD14+CD16+ monocytes in the blood and in secondary lymphoid organs. In vitro, freshly isolated blood monocytes infected with DENV up regulated CD16 and mediated robust differentiation of resting B cells to CD27++CD38++ plasmablasts and IgG and IgM secretion. Taken together, these data provide a detailed picture of the innate response to dengue infection in humans, and highlight an unappreciated role for CD14+CD16+ monocytes in promoting the differentiation of plasmablasts and mediating antibody response to DENV.

Publication Title

Dengue virus infection induces expansion of a CD14(+)CD16(+) monocyte population that stimulates plasmablast differentiation.

Chemo-resistance to platinum such as cisplatin is critical in the treatment of ovarian cancer. Recent evidences have linked epithelial-mesenchymal transition (EMT) with the drug resistance as a contributing mechanism. The current study explored the connection between cellular responses to cisplatin with EMT in ovarian cancer.

Gene expression profiling of anterior and posterior palatal tissue from Tgfbr2 mutant mouse models
  • organism-icon Mus musculus
  • sample-icon 18 Downloadable Samples
  • Technology Badge Icon Affymetrix Mouse Genome 430 2.0 Array (mouse4302)

Description

The overall goal of this project is to investigate the role of TGF-beta signaling in epithelial cells as it pertains to the orientation of muscle fibers in the soft palate during embryogenesis. Here, we first conducted gene expression profiling of the anterior and posterior portions of the palate from wild-type mice. In addition, we also conducted gene expression profiling of the posterior palate in mutant mice with an epithelium-specific conditional inactivation of the Tgfbr2 gene. The latter mice provide a model of submucosal cleft palate, which is a congenital birth defect commonly observed in many syndromic conditions.

Publication Title

TGFβ regulates epithelial-mesenchymal interactions through WNT signaling activity to control muscle development in the soft palate.

Cytokinin treatment on roots of seedlings
  • organism-icon Arabidopsis thaliana
  • sample-icon 10 Downloadable Samples
  • Technology Badge Icon Affymetrix Arabidopsis ATH1 Genome Array (ath1121501)

Description

According to the well-documented scenario with regard to the cytokinin-mediated phosphorelay signal transduction in Arabidopsis thaliana, certain members of the type-B ARR family are crucially implicated in the regulatory networks that are primarily propagated by the cytokinin-receptors (AHKs) in response to cytokinin. Nevertheless, clarification of the biological impact of these type-B ARR transcription factors is at a very early stage. Here we focused on a pair of highly homologous ARR10 and ARR12 genes by constructing an arr10 and arr12 double-null mutant. The mutant alleles used in this study were arr10-5 and arr12-1. arr10-5 is the SALK_098604 T-DNA insertion line, whose mutation was determined to be located in the fifth exon of the ARR10 coding sequence. arr12-1 is the SALK_054752 T-DNA insertion line, whose mutation was determined to be located in the third exon of the ARR12 coding sequence. The resulting mutant showed remarkable phenotypes with special reference to the cytokinin-action in roots (e.g., inhibition of root elongation, green callus formation from explants). Furthermore, we demonstrated that ARR10 and ARR12 are involved in the AHK-dependent signaling pathway that modulates the differentiation of root-vascular tissues (i.e., protoxylem-specification), suggesting that ARR10 and ARR12 are the prominent players that act redundantly in the AHK-dependent cytokinin signaling in roots. Keeping this in mind, we then collected the root-specific and combinatorial DNA microarray datasets with regard to the cytokinin-responsible genes by employing both the wild-type and arr10 arr12 double-mutant plants. In this study, wild-type and the arr10 arr12 mutant grown vertically on MS agar plates for 2 weeks were treated with 20 microM of the cytokinin trans-zeatin (TZ) or 0.02% DMSO (solvent for trans-zeatin solution) for 1h. These treated plant samples were divided into three portions, from which RNA samples were prepared separately from roots of seedlings with use of RNeasy Plant Mini Kit (Qiagen, Valencia, CA, U.S.A.). The quality of RNAs prepared was analyzed by Bioanalyzer 2100 (Agilent Technologies). These RNA samples were processed as recommended by the Affymetrix instruction (Affymetrix GeneChip Expression Analysis Technical Manual, Affymetrix). These datasets will provide us with bases for understanding the early response to cytokinin on roots of seedlings in Arabidopsis thaliana.

Cytokinin treatment on aerial parts of seedlings
  • organism-icon Arabidopsis thaliana
  • sample-icon 12 Downloadable Samples
  • Technology Badge Icon Affymetrix Arabidopsis ATH1 Genome Array (ath1121501)

Description

In Arabidopsis thaliana, the immediate early response of plants to cytokinin is formulated as the multistep AHK-AHP-ARR phosphorelay signaling circuitry, which is initiated by the cytokinin-receptor histidine protein kinases. In the hope of finding components (or genes) that function downstream of the cytokinin-mediated His-Asp phosphorelay signaling circuitry, we carried out genome-wide microarray analyses. To this end, we focused on a pair of highly homologous ARR10 and ARR12 genes by constructing an arr10 arr12 double null mutant. The mutant alleles used in this study were arr10-5 and arr12-1. arr10-5 is the SALK_098604 T-DNA insertion line, whose mutation was determined to be located in the fifth exon of the ARR10 coding sequence. Arr12-1 is the SALK_054752 T-DNA insertion line, whose mutation was determined to be located in the third exon of the ARR12 coding sequence. The resulting mutant exhibits a characteristic phenotype with regard to the cytokinin-mediated His-Asp phosphorelay. Here we, therefore, compared response to cytokinin in wild type with that in arr10 arr12 double mutant. In this study, wild type and the arr10 arr12 double mutant grown vertically on MS agar plates for 2 weeks were treated with 20uM t-zeatin or 0.02% DMSO (solvent for t-zetion solution) for 1h. These treated plant samples were divided into three portions, from which RNA samples were prepared separately from aerial parts of seedlings with use of RNeasy Plant Mini Kit (Qiagen, Valencia, CA, U.S.A.). The Quality of RNAs prepared was analyzed by Bioanalyzer 2100 (Agilent Technologies). These RNA samples were processed as recommended by the Affymetrix instruction (Affymetrix GeneChip Expression Analysis Technical Manual, Affymetrix). These dataset will provide us with bases for understanding the early response to cytokinin on aerial parts of seedlings in Arabidopsis thaliana.

Effect of DMHF (2,5-dimethyl-4-hydroxy-3(2H)-furanone) inhalation on gene expression in Rat brain
  • organism-icon Rattus norvegicus
  • sample-icon 10 Downloadable Samples
  • Technology Badge Icon Affymetrix Rat Genome 230 2.0 Array (rat2302)

Description

Background: 2,5-Dimethyl-4-hydroxy-3(2H)-furanone (DMHF) is one of the major odor compounds generated by the Maillard reaction. We previously reported that the inhalation of DMHF decreased systolic blood pressure via the autonomic nervous system in rats. The autonomic nervous system is also closely related to appetite regulation. The present study investigated the effects of DMHF on dietary intake and gene expression.

Publication Title
