Saccharomyces cerevisiae grown in nitrogen depletion with oligodT priming

ABSTRACT: Multi-targeting priming (MTP) for genome-wide gene expression assays provides selective targeting of multiple sequences and counter-selection against undesirable sequences. We demonstrated superior performance of two MTPs compared to oligo-dT microarray profling and RNA tag sequencing the response of Saccharomyces cerevisiae to nitrogen deficiency and profiling Neurospora crassa early sexual development. Priming with MTPs in addition to oligo-dT resulted in higher sensitivity, a greater number of well-measured genes, more genes significantly differentially expressed, and a greater power to detect meager differences.

Serum Starvation/Refeeding RNA vs. RAP

Project description:Low abundance mRNAs are more difficult to examine using microarrays than high abundance mRNAs due to the effect of concentration on hybridization kinetics, signal-to-noise ratios, and interference between signals from mRNA isoforms. Individual sequences in LCRs are more highly represented than in the mRNA population from which they are derived, leading to favorable hybridization kinetics. LCR targets permit the measurement of abundance changes that are difficult to measure using oligo dT priming for target synthesis. An oligo dT-primed target and three LCRs detect twice as many differentially regulated genes as could be detected by the oligo dT-primed target alone, as serum-starved fibroblasts responded to the reintroduction of serum. Thus, this target preparation strategy considerably increases the sensitivity of spotted cDNA microarrays. Keywords: parallel sample
