(Submitter supplied) Both spotted long oligonucleotide arrays and Affymetrix GeneChips were used to measure differential gene expression in two RNA samples (K562 erythroleukemia RNA and the Stratagene Universal Human Reference RNA). For Affymetrix technology, the two RNAs were analyzed separately. There are two replicates for K562 RNA (GSM4843 and GSM4844) and three for the Stratagene Universal reference (GSM4845-GSM4847). more...

(Submitter supplied) We analysed the transcriptional effects of the TOR2-controlled signaling function using a genome-wide microarray approach in yeast. In S. cerevisiae, TOR2 has two essential signaling functions. One, shared with TOR1, is required for translation initiation, transcription, and cell growth in response to the presence of nutrients. The second is unique to TOR2, and functions in cell-cycle-dependent actin polarization and possibly in transcription. more...

(Submitter supplied) Background:Alternative splicing and isoform level expression profiling is an emerging field of interest within genomics. Splicing sensitive microarrays, with probes targeted to individual exons or exon-junctions, are becoming increasingly popular as a tool capable of both expression profiling and finer scale isoform detection. Despite their intuitive appeal, relatively little is known about the performance of such tools, particularly in comparison with more traditional 3’ targeted microarrays. more...

(Submitter supplied) There is an increasing interest on the role of Alternative splicing (AS) in different pathologies. The Affymetrix Human Transcriptome Array (HTA 2.0) can be used to explore AS very efficiently. However, the interpretation software provided by its vendor (TAC 3.0) does not fully exploit its potential and can only be applied to case-control studies. EventPointer is an R package to identify Alternative Splicing events using HTA 2.0 arrays. more...

(Submitter supplied) Microarray technology provides a powerful tool for defining gene expression profiles of airway epithelium that lend insight into the pathogenesis of human airway disorders. The focus of this study was to establish rigorous quality control parameters to ensure that microarray assessment of the airway epithelium is not confounded by experimental artifact. Samples (total n=223) of trachea, large and small airway epithelium were collected by fiberoptic bronchoscopy of 144 individuals (42 healthy non-smokers, 49 healthy smokers, 11 symptomatic smokers, 22 smokers with lone emphysema with normal spirometry, and 20 smokers with COPD) were processed and hybridized to Affymetrix HG-U133 2.0 Plus microarrays. more...

(Submitter supplied) Purified DNA of some 4600 overlapping shotgun clones in vector pCR-BluntII-TOPO (Invitrogen, Groningen, The Netherlands) was used as template in standard PCR amplification with the vector-specific primer pair d(TCGGATC CACTAGTAACG) and d(GGCCGCCAGTGTGATG). Shotgun cloning had been performed according to the procedures described by the vector's manufacturer. Each PCR reaction was individually checked by agarose gel electrophoresis. more...

(Submitter supplied) Knowledge of the biological and technical variation for fermentor-grown Aspergillus niger cultures is needed to design DNA microarray experiments properly. We cultured A. niger in batch-operated fermentor vessels and induced with D-xylose. Transcript profiles were followed in detail by qPCR for 8 genes. A variance components analysis was performed on these data to determine the origin and magnitude of variation within each process step for this experiment. more...

(Submitter supplied) Variance in microarray studies has been widely discussed as a critical topic of the identification of differentially expressed gene; however, few studies have addressed the influence of estimating variance. To break intra- and inter-individual variance in clinical studies down to three levels: technical, anatomic, and individual, we designed experiments and algorithms to investigate three forms of variances. more...
