Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
Research in human immunobiology is mainly based on working with peripheral blood mononuclear cells (PBMC). However, recent investigations have shown that circulating CD4+ T cells are less sensitive to several T-cell activating monoclonal antibodies (mAb) and to recall antigens as compared to tissue-resident cells or cells that were in-vitro cultured at a high cell density of 10^7 cells/mL for 2 days at 37C and 5% CO2 (RESTORE protocol, Rmer et al., Blood 2011, PMID: 21931118). To explain the increase in sensitivity of CD4+ T-cells to mAbs and recall antigens on a molecular level, we performed microarray hybridizations of total RNA from T-cells isolated from PBMC that were cultured at a low or high cell density. To avoid the detection of genes that are up- or down-regulated by the culture process itself, we used low cell density cultured PBMC, instead of freshly prepared PBMC.

- Affymetrix Mouse Gene 1.0 ST Array (mogene10st)
Description
Parietal epithelial cells (PECs) are crucially involved in the pathogenesis of rapidly progressive glomerulonephritis (RPGN) as well as in focal and segmental glomerulosclerosis (FSGS). In this study, transgenic mouse lines were used to isolate pure, genetically tagged primary cultures of PECs or podocytes using FACsorting. By this approach, the morphology of primary glomerular epithelial cells in culture could be resolved: Primary podocytes formed either large cells with intracytoplasmatic extensions or smaller spindle shaped cells, depending on specific culture conditions. Primary PECs were small and exhibited a spindle-shaped or polygonal morphology. In the very early phases of primary culture, rapid changes in gene expression (e.g. of WT-1 and Pax-2) were observed. However, after prolonged culture primary PECs and podocytes still segregated clearly in a transcriptome analysis - demonstrating that the origin of primary cell cultures is important. Of the classical markers, synaptopodin and podoplanin expression were differentially regulated the most in primary PEC and podocyte cultures. However, no expression of any endogenous gene allowed to differentiate between the two cell types in culture. Finally, we show that the transcription factor WT1 is also expressed by PECs. In summary, genetic tagging of PECs and podocytes is a novel and necessary tool to derive pure primary cultures with proven origin. These cultures will be a powerful tool for the emerging field of parietal epithelial cell biology.

Description
The discovery of activity-dependent neuroprotective protein (ADNP) regulated tooth eruption in mice and man, provides, for the first time, an early detection of tooth eruption, with full or almost full mouth of teeth at one year of age, as a potential biomarker for an intellectual disability (ID)/autism spectrum disorder (ASD) syndrome, toward improved translational medicine. Overall design: RNAseq of 4 samples, comparing three ADNP-mutated lymphoblastoid cell lines (LCLs, derived from ADNP-mutated children) with a non-mutated cell line. No replicates were performed but results were verified usign RT-PCR.

Description
A key function of Na+/H+ exchanger regulatory factor 2 (NHERF2) is spatial organization of signaling proteins to facilitate signal transduction. The role of NHERF2 in cancer progress is not well understood. This study determines how loss of NHERF2 alter colon cancer progress. Overall design: We show that loss of NHERF2 decreases colon cancer cell proliferation. To compare the effects of NHERF2 and LPA2 at the molecular level, HCT116 colon cancer xenograft with knockdown of NHERF2 or LPA2 was analyzed by RNAseq. Please note that standard cufflinks/cuffdiff output files are provided in the compressed tar files as processed data and Cufflinks/Cuffdiff output file content/formats are described at: https://cole-trapnell-lab.github.io/cufflinks/cuffdiff/#cuffdiff-output-files https://cole-trapnell-lab.github.io/cufflinks/file_formats/ (also included in the ''readme.txt'' file)

Description
Experiments in rodents have shown that kidney ischemia/reperfusion injury (IRI) facilitates lung injury and inflammation. To identify potential ischemia-specific lung molecular pathways involved, we conducted global gene expression profiling of lung 6 or 36 hours following 1) bilateral kidney IRI, 2) bilateral nephrectomy (BNx), and 3) sham laparotomy in C57BL/6J mice. Total RNA from whole lung was isolated and hybridized to 430MOEA (22,626 genes) GeneChips (n=3/group).

Description
Drosophila miRNAs show distinct change in isoform distribution pattern with age. Some miRNAs show accumulation of the short isoforms, while other miRNAs show the accumulation of the long isoforms with age. The increase of the long isoforms of some miRNAs reflects increased 2''-O-methylated miRNA isoforms with age. The increase in 2''-O-methylated miRNA isoforms reflected increased Ago2-loading, but not Ago1-loading of specific miRNA isoforms with age. This raised a question on whether there is global shift in small RNA loading pattern between Ago1 and Ago2 with age. To investigate change in small RNA loading pattern between Ago1 and Ago2 with age, we performed small RNA deep-sequencing of Ago1 vs Ago2-IP small RNAs at 3d and 30d in Drosophila. This analysis revealed global increase of miRNA loading into Ago2, but not into Ago1 with age. Overall design: 3d and 30d FLAG-HA-Ago2 male flies were collected. Ago1 and Ago2 were immunoprecipitated by anti-Ago1 and anti-FLAG M2 beads respectively. RNA was purified from the beads, P32-labeled, and small RNA fraction was gel-purififed. Small RNA libraries were prepared using Illumina''s TruSeq small RNA sample preparation kit (#RS-200-0012, Illumina, Inc. San Diego, CA), following the manufacturer''s protocol. The libraries were multiplexed and sequenced on HiSeq2000 platform (Illumina).
