Illumina HumanHT-12 V4.0 expression beadchip
Description
To induce a differentiated phenotype, primary pancreatic TIC cultures were grown in 10% FBS containing conditions. To analyze gene expression changes upon induction of a differentiated phenotype, total RNA of cells cultured in FBS containing conditions and parallel control cells cultured under serum-free conditions was isolated and comparative gene expression profiling was performed.

Description
Non-small cell lung cancer (NSCLC) can be classified into the major subtypes adenocarcinoma (AC) and squamous cell carcinoma (SCC) subtypes. Although explicit molecular, histological and clinical characteristics have been reported for both subtypes, no specific therapy exists so far. However, the characterization of suitable molecular targets holds great promises to develop novel therapies in NSCLC. In the present study, global gene expression profiling of 58 human high grade NSCLC specimens revealed large transcriptomic differences between AC and SCC subtypes: More than 1.700 genes were found to be differentially expressed.

Description
We investigated whether biomarker analysis in endobronchial epithelial lining fluid (ELF) collected by bronchoscopic microsampling may be useful for a definitive preoperative diagnosis. Therefore we compared ELF samples close to nodule and from the contralateral site from patients with malignant or benign diagnosis.

Description
Dilated cardiomyopathy (DCM) is a common cause of heart failure and a leading cause of cardiac transplantation in western countries. The robust predictive expression profile of cardiomyopathic and NF hearts as well as the functional classification can help to identify promising candidates for DCM and may improve the early diagnosis of cardiomyopathy.

Description
The stromal microenvironment plays a vital role in cancer initiation and progression. We performed a comparative expression profiling of pulmonary MSC derived from NSCLC and corresponding normal lung tissue of 5 newly diagnosed patients. The analysis indicated variable expression of genes involved in DNA repair, apoptosis, proliferation or angiogenesis between NSCLC-MSC and NLT-MSC.

Description
Tumor progression is associated with an immunosuppressive microenvironment that consists of several elements, such as regulatory T cells, type 2 macrophages and myeloid-derived suppressor cells. Here, we identify for the first time a BDCA1+CD14+ population of immunosuppressive cells that resides both in the blood and tumor of melanoma patients. We demonstrated that the presence of these cells in dendritic cell (DC)-based anti-tumor vaccines significantly suppresses CD4+ T cells in an antigen-specific manner. In an attempt to reveal the mechanism of this suppressive activity, we noticed that BDCA1+CD14+ cells express elevated levels of the check-point molecule PD-L1, which thereby hinders T cell proliferation. Importantly, although this suppressive BDCA1+CD14+ population expresses markers of both BDCA1+ DCs and monocytes, functional, transcriptome and proteome analyses clearly revealed that they comprise a unique population of cells that is exploited by tumors to evade immunity. Thus, targeting these cells may improve the efficacy of cancer immunotherapy.

- Affymetrix Human Genome U95 Version 2 Array (hgu95av2)
Description
Rotavirus infection is the single most important cause of severe diarrhea in young children worldwide. We used Affymetrix Human U95Av2 high density oligonucleotide arrays to compare gene expression profiles in peripheral blood mononuclear cells (PBMC) of 10 children with acute rotavirus diarrhea and 8 age-matched healthy children. We also examined patterns of gene expression in 5 convalescent-phase PBMC samples from rotavirus patients. For data analysis, we imported .cel files generated by Affymetrix MAS5.0 into Genetraffic 3.1 software (Iobion) and performed robust multi-chip analysis. We considered a gene in patients differentially expressed if its level of expression was at least 1.5-fold higher or lower than the baseline (arithmetic mean) of the corresponding gene in 8 controls and if its pattern of elevated or repressed expression was observed in at least 7 of the 10 patients. Using these criteria, we identified ~1% up- and ~2% down-regulated genes in acute-phase PBMC of patients. Up-regulated genes included those involved in the differentiation, maturation, activation, and survival of B cells, as well as an array of genes with function in inflammatory and antiviral activities. We observed a pattern of repressed expression of a number of genes involved in the various stages of T-cell development and activation. On the basis of these results, we conclude that rotavirus infection induces robust inflammatory response and B-cell activation but represses T-cell response.
