Description
To identify genes that mediate altered communication between fat body and peripheral tissues, we report the gene expression changes in Drosophila third instar larval fat bodies with or without constitutively-active Toll (Toll10b) to activate innate immune signaling, myristoylated Akt (myrAkt) to activate insulin signaling, or both transgenes to bypass the block from Toll signaling to the upstream part of the insulin signaling pathway Overall design: Comparison of RFP/GFP (Control), Toll10b/GFP (Toll10b), RFP/myrAkt (myrAkt), and Toll10b/myrAkt (Toll10b + myrAkt)

Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
Resident stem/progenitor cells in the lung are important for tissue homeostasis and repair. However, a progenitor population for alveolar type II (ATII) cells in adult human lungs have not been identified. Here we isolated alveolar epithelial progenitor cells (AEPCs) from adult human lungs. AEPCs showed mesenchymal stem cell (MSC)-like characteristics combined with ATII cell-phenotypes. AEPCs had the capability for self-renewal and the potential to generate ATII cells in vitro. Furthermore, cells expressing similar markers were present within alveolar walls in normal lungs and these cells were significantly increased in ATII cell hyperplasias. These results suggest that adult human lungs contain a progenitor population for ATII cells.

Description
Human mesenchymal stem cells (hMSCs), which are multipotent cells to differentiate into several cell types, are expected to be a useful tool for cellular therapy. In some clinical settings, hMSCs have immuno-suppressive effects for GVHD (Graft-versus-host disease) and are expanded in vitro before application. To find biomarkers that indicate the culture stage of hMSCs, we performed microarray analysis for hMSCs derived from bone marrow, using Affymetrix GeneChip Human Genome U133 Plus 2.0 (54,613 probe sets).

Description
Tissue morphogenesis relies on proper differentiation of morphogenetic domains, adopting specific cell behaviours. Yet, how signalling pathways interact to determine and coordinate these domains remains poorly understood. Dorsal closure (DC) of the Drosophila embryo represents a powerful model to study epithelial cell sheet sealing. In this process, JNK (JUN N-terminal Kinase) signalling controls leading edge (LE) differentiation generating local forces and cell shape changes essential for DC. The LE represents a key morphogenetic domain in which, in addition to JNK, a number of signalling pathways converges and interacts (anterior/posterior -AP- determination; segmentation genes, such as Wnt/Wingless; TGF/Decapentaplegic). To better characterize properties of the LE morphogenetic domain, we used microarrays to identify genes whose expression is regulated by the JNK pathway during dorsal closure of the Drosophila embryo.

Description
Prostate cancer is the most common cancer in men and AR downstream signalings promote prostate cancer cell proliferation. Androgen-deprivation therapy is the first-line treatment strategy for advanced prostate cancer. However, many tumors develop to castration-resistant prostate cancer (CRPC) and relapse. Thus, analyzing key factors for development of CRPC is important. We found PSF functions as RNA binding protein and transcription factor to promote castration-resistant tumor growth. High expression of PSF in metastatic prostate cancer tissue indicates the clinical relevance.

Description
Alveolar epithelial type II (ATII) cells play a critical role in homeostasis and repair process of the lungs. In lung diseases such as chronic obstructive pulmonary disease (COPD), ATII cells are damaged and fall into apoptosis or senescence. Until to date, global gene expression of ATII cells in COPD lungs has not been analyzed. We isolated ATII cells from three non-COPD and three COPD patients using a FACS method. Then, we performed microarray analysis to compare gene expression profiles of ATII cells between non-COPD and COPD patients.

Description
We developed a novel culture system to obtain multilineage undifferentiated stem/progenitor cells from normal human thyroid tissues. This seems to be achieved by direct reprogramming of thyroid follicular cells. The objective of the study was to reveal gene expression profile of the obtained cells compared to primary thyrocytes. After enzymatic digestion, primary thyrocytes, expressing thyroglobulin and cytokeratin-18, were cultured in a serum-free medium called SAGM containing insulin and EGF. Although the vast majority of cells died, a small proportion (~0.5%) survived and proliferated. During initial cell expansion, thyroglobulin/cytokeratin-18 expression was gradually declined, suggesting that those cells are derived from thyroid follicular cells or at least thyroid-committed cells. The SAGM-grown cells did not express any thyroid-specific genes. However, after four-week incubation with FBS and TSH, cytokeratin-18, thyroglobulin, TSH receptor, PAX8 and TTF1 expressions re-emerged. Moreover, surprisingly, the cells were capable of differentiating into neuronal or adipogenic lineage depending on differentiating conditions.
