(Submitter supplied) Determination of 3' or 5' intragenic RNA pol II occupancy. Maintaining the proper mRNA levels is a key aspect in the regulation of gene expression. The balance between mRNA synthesis and decay determines these levels. Using a whole-genome analysis, we demonstrate that most yeast mRNAs are degraded by the 5'-to-3' pathway (the "decaysome"), as proposed previously. Unexpectedly, the level of these mRNAs is highly robust to perturbations in this major pathway, as defects in various decaysome components lead to transcription down-regulation. more...

(Submitter supplied) Isogenic UPF1+ or upf1- yeast strains were treated with 10 ug/ml thiolutin to inhibit global transcription. Targets were obtained from 16 time points: 0, 2, 4, 6, 8, 10, 12, 15, 20, 25, 30, 35, 40, 45, 50, 60 minutes after transcription inhibition. Three biological replicates of each were generated and the expression profiles were determined using Affymetrix YG-S98 arrays. Comparisons between the sample groups allow the identification of genes with differential expression over time between UPF1+ and upf1-. more...

(Submitter supplied) We have taken five different time points of a Yeast culture in exponential grow in rich medium, each one elapsed ten minutes from de previous one (from OD600 0.36 to 0.47). Then, for each time point we have measured the transcription rates (TR) and mRNA amounts (RA) for all the genes using the Genomic run-on (GRO) technique .

Genome-wide mRNA expression profiles of Saccharomyces cerevisiae growing under hydrostatic pressure were characterized. We selected a hydrostatic pressure of 30 MPa at 25°C because yeast cells were able to grow under these conditions, while cell size and complexity were increased after decompression. more...
