Expression profiling of breast cancer cell lines HCC 1954 and MDA-MB-436 in reference to mammary epithelial cells. Results used to validate a method of comparing data generated from cDNA arrays to that from Affymetrix arrays. The method uses DNA sequence to match probes between platforms.

(Submitter supplied) Primary cultures of human trophoblasts were established from normal, term placenta. Cells were treated five hours after plating. This sample was treated with 1 uM GW7845. RNA was extracted after 48 hours of treatment using Tri-reagent. Each sample was pooled from three individual placentas prior to target generation. Targets were produced using standard Affymetrix procedures from 30ug of total RNA. Keywords: parallel sample

(Submitter supplied) Compatibility between high-density oligonucleotide arrays is significantly affected by probe-level sequence information. With a careful filtering of the probes based on their sequence overlaps, data from different generations of microarrays can be combined more effectively. The dataset of 14 human muscle biopsy samples from patients with inflammatory myopathies that were hybridized on both HG-U95Av2 and HG-U133A human arrays for this purpose. more...

(Submitter supplied) Microarrays have been widely used for the analysis of gene expression and several commercial platforms are available. The combined use of multiple platforms can overcome the inherent biases of each approach, and may represent an alternative that is complementary to RT-PCR for identification of the more robust changes in gene expression profiles. In this paper, we combined statistical and functional analysis for the cross platform validation of two oligonucleotide-based technologies, Affymetrix (AFFX) and Applied Biosystems (ABI), and for the identification of differentially expressed genes. more...

(Submitter supplied) To assist in the identification of proteases, their endogenous inhibitors, and proteins that interact with proteases or proteolytic pathways in biological tissues, a dual species oligonucleotide microarray has been developed in conjunction with Affymetrix, Inc. To investigate the performance of the array, gene expression profiles were analyzed in pure mouse and human samples and orthotopically implanted xenografts of human A549 lung and MDA-MB-231 breast carcinomas. more...

(Submitter supplied) The growth in popularity of RNA expression microarrays has been accompanied by concerns about the reliability of the data especially when comparing between different platforms. Here we present an evaluation of the reproducibility of microarray results using two platforms, Affymetrix GeneChips and Illumina BeadArrays. The study design is based on a dilution series of two human tissues (blood and placenta), tested in duplicate on each platform. more...

(Submitter supplied) Gene expression microarrays have made a profound impact in biomedical research. The diversity of platforms and analytical methods has made comparison of data from multiple platforms very challenging. In this study, we describe a framework for comparisons across platforms and laboratories. We have attempted to include nearly all the available commercial and in house platforms. Using probe sequences matched at the exon level improved consistency of measurements across the different microarray platforms compared to annotation-based matches. more...
