(Submitter supplied) The maize spikelet contains two florets, each of which contains three anthers. Morphologically, the anthers in the upper and lower florets proceed through the same developmental program. To test for global differences in gene expression between these anthers and to identify genes that are coordinately regulated during development, RNA isolated from upper and lower floret anthers at six developmental stages was used to hybridize cDNA microarrays. 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) A novel porcine cDNA microarray, containing PCR products selected for embryonic expression, was used for transcriptional profiling during conceptus development. Total RNA from quadruplicate samples of small spherical (1-5mm), large spherical (6-11mm), tubular (13-45mm), and filamentous (>100mm) was extracted, amplified, and converted to 32P labeled target and hybridized to membranes. Porcine peri-implantation embryo development order is from small spherical to large spherical, then to Tubular, then to filamentous. more...

(Submitter supplied) In this study we evaluate the Swine Protein-Annotated Oligonucleotide Microarray by profiling the expression of transcripts in four porcine tissues. We validate the hybridization results by comparative analysis of expression in human orthologs, confirm expression patterns for a subset of genes by QPCR, and assess the usefulness of designed control oligonucleotides. Simple descriptive diagnostic analyses of PM/MM probe sets introduced in this paper are useful to detect non-specific hybridization. more...

(Submitter supplied) A number of methods have been proposed to incorporate multiple scans at different intensities to reduce the quantification error and to minimize effects of saturation, but no direct comparison of their efficacy has been made. Here we used 40 technical replicates to compare individual scans at low, medium and high sensitivity with three methods for combining data from multiple scans (either 2 scan or 3 scan cases) using a variety of metrics Keywords: Multiple Scans

(Submitter supplied) The aim of the study was to identify markers for the early diagnosis of endoprosthesis loosening, for the differentiation between wear-particle induced and septic loosening, as well as to gather new insights into the pathogenesis. 824 genes were differentially expressed with a fold change greater than 2. Among these were Chitinase 1, CD52, Calpain 3, Apolipoprotein, CD18, Lysyl oxidase, Cathepsin D, E-Cadherin, VE-Cadherin, Nidogen, Angiopoietin 1 and Thrombospondin 2, and the differential expression levels were validated by RT-PCR. more...
