Project description:To identify potential target genes of leukemia-related miRNAs such as miR-196b and miR-150 in human MLL-associated leukemia, we performed Affymetrix Human Exon 1.0 ST array assay of 15 human MLL-associated samples and 9 human normal bone marrow (including 3 each of CD34+, CD33+, and MNC) cell samples.
Project description:To identify potential target genes of leukemia-related miRNAs such as miR-196b and miR-150 in human MLL-associated leukemia, we performed Affymetrix Human Exon 1.0 ST array assay of 15 human MLL-associated samples and 9 human normal bone marrow (including 3 each of CD34+, CD33+, and MNC) cell samples. A total of 15 MLL-associated (9 primary untreated leukemia and 6 leukemia cell line) samples and 9 human normal bone marrow samples (including 3 each of CD34+ hematopoietic stem/progenitor, CD33+ myeloid, and mononuclear cell (MNC) samples) were analyzed by use of Affymetrix Human Exon 1.0 ST arrays (Affymetirx, Santa Clara, CA).
Project description:The Affymetrix Human Exon 1.0 ST array was used to measure differential splicing patterns in archived RNA isolated from 26 of 80 children (11 Rejectors and 15 Non-Rejectors). The exon-level probe summaries reported in this series were computed using the Affymetrix Power Tools (APT) software and 'rma-sketch' normalization method. Keywords: Affymetrix 1.0 ST exon array; exon-level analysis
Project description:Bone marrow-derived macrophages from Dhps fl/fl mice and mice with specific deletion of Dhps in myeloid cells were infected with Helicobacter pylori PMSS1 for 24 hours. Cells were washed and lysed. Proteins were analyzed by isobaric tags for relative and absolute quantitation (iTRAQ).
Project description:The aim of the experiment was to evaluate the performance of the Affymetrix Brassica Exon 1.0 ST array. Root and leaf samples from Brassica rapa line R-O-18 were compared. The same RNA samples were hybridised to the Agilent Brassica array, to compare the performance of the two arrays.
Project description:The presence of different transcripts of a gene across samples can be analysed by whole-transcriptome microarrays. Reproducing results from published microarray data represents a challenge owing to the vast amounts of data and the large variety of preprocessing and filtering steps used before the actual analysis is carried out. To guarantee a firm basis for methodological development where results with new methods are compared with previous results, it is crucial to ensure that all analyses are completely reproducible for other researchers. We here give a detailed workflow on how to perform reproducible analysis of the GeneChip®Human Exon 1.0 ST Array at probe and probeset level solely in R/Bioconductor, choosing packages based on their simplicity of use. To exemplify the use of the proposed workflow, we analyse differential splicing and differential gene expression in a publicly available dataset using various statistical methods. We believe this study will provide other researchers with an easy way of accessing gene expression data at different annotation levels and with the sufficient details needed for developing their own tools for reproducible analysis of the GeneChip®Human Exon 1.0 ST Array.

The same RNA samples were hybridised to the Agilent Brassica array, to compare the performance of the two arrays. 6 samples were hybridised to each array. Triplicate samples of 11-day-old roots and 2 semi-expanded leaves from 23-day-old Brassica rapoa R-O-18 plants.
Project description:Macrophages were derived from the bone-marrow of 3 x fl/+ Dicer LysCre +/- (wild-type) and 3 x fl/fl Dicer LysCre +/- mice and stimulated with IL-4 (50ng/mL) for 72h. Total RNA was isolated and analyzed by gene array. In this experiment, we derived Dicer deficient bone-marrow macrophages using Dicer fl/+ LysM-Cre by Dicer fl/+ crossed mice to obtain Dicer fl/fl LysM-cre progeny (and Dicer deficient macrophages). Next, we studied the effects of IL-4 stimulation in macrophage with a deficiency in Dicer/microRNAs.
