View SamplesMAP kinases are integral to the mechanisms by which cells respond to a wide variety of environmental stresses. In Caenorhabditis elegans, the KGB-1 JNK signaling pathway regulates the response to heavy metal stress. The deletion mutants of this cascade show hypersensitivity to heavy metals like copper or cadmium. However, factors that function downstream of KGB-1 pathway are not well characterized.
The Caenorhabditis elegans JNK signaling pathway activates expression of stress response genes by derepressing the Fos/HDAC repressor complex.

View SamplesAccording 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.

View SamplesIn 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.

View Samplesc-Myc is one of key players that are crucially involved in maintaining the undifferentiated state and the self-renewal of ESCs. To understand the mechanism by which c-Myc helps preserve these prominent characteristics of ESCs, we generated null-ES cells for the Max gene, which encodes the best characterized partner protein for all Myc family proteins. Although Myc/Max complexes have been widely regarded as crucial regulators of the ESC status, our data reveal that ESCs do not absolutely require these complexes in so-called ground state or related conditons and that this requirement is restricted to conventional ES culture conditions without using a MAPK inhibitor.

View SamplesIdiopathic pulmonary fibrosis (IPF) is a lethal interstitial lung disease causing alveolar remodeling, inflammation, and fibrosis. We utilized single cell RNA-sequencing (scRNA-Seq) to identify epithelial cell types and associated biological processes involved in the pathogenesis of IPF. Transcriptomic analysis of epithelial cells from normal human lung defined gene expression patterns associated with highly differentiated alveolar type 2 (AT2) cells, indicated by enrichment of RNAs critical for surfactant homeostasis. In contrast, scRNA-seq of IPF cells identified three distinct subsets of epithelial cell types with characteristics of conducting airway basal and goblet cells and, an additional atypical "transitional" cell that contribute to pathological processes in IPF. Individual IPF cells frequently co-expressed alveolar AT1, AT2, and conducting airway selective markers, demonstrating "indeterminate" states of differentiation not seen in normal lung development. Pathway analysis predicted aberrant activation of canonical signaling via TGF-ß, HIPPO/YAP, P53, and AKT-PI3 Kinase. Immunofluorescence confocal microscopy identified the disruption of alveolar structure and loss of the normal proximal-peripheral differentiation of pulmonary epithelial cells. Single cell transcriptomic analyses of respiratory epithelial cells identified loss of normal epithelial cell identities and unique contributions of epithelial cells to the pathogenesis of IPF. Present scRNA-seq transcriptomic analysis of normal and IPF respiratory epithelial cells provides a rich data source to further explore lung health and disease. Overall design: Dissociated single-cell preparations from peripheral lung of IPF patients (n = 3) and controls (n = 3) from cohort 2 were enriched for AT2 epithelial cells by FACS for CD326 (CD326) double positive, CD45 (hematopoietic) negative, CD31 (endothelial) negative cells, and HTII-280 after dissociation by proteases.
