Description
Tumor microenvironments present significant barriers to anti-tumor agents. Molecules involved in multicellular tumor microenvironments, however, are difficult to study ex vivo. Here, we generated a matrix-free tumor spheroid model using the NCI-H226 mesothelioma cell line and compared the gene expression profiles of spheroids and monolayers using microarray analysis. Microarray analysis revealed that 142 probe sets were differentially expressed between tumor spheroids and monolayers. Gene ontology analysis revealed that upregulated genes were primarily related to immune response, wound response, lymphocyte stimulation and response to cytokine stimulation, whereas downregulated genes were primarily associated with apoptosis. Among the 142 genes, 27 are located in the membrane and related to biologic processes of cellular movement, cell-to-cell signaling, cellular growth and proliferation and morphology. Western blot analysis validated elevation of MMP2, BAFF/BLyS/TNFSF13B, RANTES/CCL5 and TNFAIP6/TSG-6 protein expression in spheroids as compared to monolayers. Thus, we have reported the first large scale comparison of the transcriptional profiles using an ex vivo matrix-free spheroid model to identify genes specific to the three-dimensional biological structure of tumors. The method described here can be used for gene expression profiling of tumors other than mesothelioma.

Description
TGFBR1*6A is a common hypomorphic variant of the type 1 Transforming Growth Factor Beta Receptor (TGFBR1), which has been associated with increased cancer risk in some studies. Although TGFBR1*6A is capable of switching TGF- growth inhibitory signals into growth stimulatory signals when stably transfected into MCF-7 breast cancer cells, TGFBR1*6A biological effects are largely unknown. To broadly explore TGFBR1*6A potential oncogenic properties, we assessed its impact on the migration and invasion of MCF-7 cells. We found that TGFBR1*6A significantly enhances MCF-7 cell migration and invasion in a TGF- signaling independent manner. We set up and performed a gene array using the conditions mimicking the cell migration experiments to determine which genes in the migratory pathway were differentially regulated between the MCF-7*6A cells and the MCF-7*9A (wild type transfected) cells. The gene array identified two downregulated genes in *6A compared to *9A that are involved in cell migration and invasion: ARHGAP5, encoding ARHGAP5, and FN1, encoding fibronectin-1 (FN1). We were subsequently able to use this information in further studies in the lab.

Description
The aim of this study is to address the functional role of miRNAs in the FoxD1+ renal stroma progenitors and derivatives during embryonic kidney development. To achieve this, we generated transgenic mice that lack miRNAs in the renal stroma lineage (FoxD1 Cre;Dicer), and performed a microarray analysis on E15.5 whole kidneys to determine the transcriptional changes.

Description
MCF-7aro cells were used to generate a cell culture model system that is resistant to 3 aromatase inhibitors (AIs), letrozole, anastrozole and exemestane. For comparison, the MCF-7aro cells were also used to generate the tamoxifen-resistant cells as well as long-term estrogen deprived, LTEDaro.

Description
Analysis of gene expression of Pdx-EGFP1+ pancreatic progenitors before or after co-culture at mRNA level. The hypothesis tested in the study was that the overall gene expression in Pdx1-EGFP+ does not alter after co-culture with endothelial cells. The result supported our hypothesis. Overall design: Total RNA isolated from Pdx1-EGFP+ progenitors from the Pdx1-EGFP HUES8 cell-derived pancreatic progenitor population before (none) and after co-culture (AKT-HUVEC, MPEC, or BJ) Fig 2d in publication.
