GRO analysis of rap1-sil, tpk1 & tpk2.

ABSTRACT: GRO (Genomic run-on) experiments with different mutants that affect to the accumulation of non active RNA pol II along the yeast genome. Keywords: Genomic run-on GRO There are 4 different strains: rap1-sil (without the silencing domain), RAP1(both from Graham I.R. et al 1999) and tpk1 & tpk2 mutants (Euroscarf). For each experiment there are GRO data (Transcription Rate) and gDNA data used for normalizing the GRO signals. The last number of the GRO filters correspond to the number of gDNA filters.There are 3 independent biological replicates of Rap1 and rap1-sil experiments and 2 for the tpk1 & tpk2 experiments.

Regulon-specific control of transcription elongation across the yeast genome.

Pelechano Vicent V Jimeno-González Silvia S Rodríguez-Gil Alfonso A García-Martínez José J Pérez-Ortín José E JE Chávez Sebastián S

PLoS genetics 20090821 8

Transcription elongation by RNA polymerase II was often considered an invariant non-regulated process. However, genome-wide studies have shown that transcriptional pausing during elongation is a frequent phenomenon in tightly-regulated metazoan genes. Using a combination of ChIP-on-chip and genomic run-on approaches, we found that the proportion of transcriptionally active RNA polymerase II (active versus total) present throughout the yeast genome is characteristic of some functional gene classe ...[more]

Yeast mRNA decay analysis after addition of 3 Âµ/mL thiolutin

Project description:Time course after the addition of the transcriptional inhibitor thiolutin at 3Âµg/mL to an exponential growing culture of S. cerevisiae in YPD. Total RNA from BQS252 yeast strain (Mat a, ura 3-52 derived from FY1679) growing in exponential phase in YPD was extracted at different times after thiolutin 3Âµg/mL addition. All the samples were hybridized on the same nylon array. In order to estimate mRNA stability the intensities where normalized using global poly(A) data from a RNA dot-blot and assuming a first order decaying. There is only 1 replicate.

GRO analysis of topoisomerase mutants

Project description:Genomic Run-on analysis of topoisomerase mutants (top1-delta/top2ts or top2ts) has been conducted at reference temperature for wt strain and at non-permissive temperature for wt and mutant strains. Keywords: Genomic Run On The analysis includes 3 repeats of the wild type strain (JCW25) at 30ÂºC and 3 more at 37ÂºC, 3 repeats of the top2ts mutant (JCW26) at 37ÂºC and 3 repeats of the double top1 (delta) top2ts mutant at 37ÂºC. A single genomic DNA hybridization on one of the filters can be used for normalization between gene probes if needed.

Comparison of natural yeast hybrids

Project description:Analysis of genomic variation in several Saccharomyces cerevisiae x S. kudriavzevii natural hybrids S. cerevisiae and S. kudriavzevii yeasts have been described among wine strains. These strains exhibit enological properties of interest for the wine industry. A preliminary characterization of these hybrids showed a trend to reduce the S. kudriavzevii fraction of the hybrid genome. As a first approach to understand the mechanisms involved in the genome changes occurred after hybridization that may account for differences in their enological properties, we characterized the genomic constitution of several wine S. cerevisiae x S. kudriavzevii strains by using a combined approach based on the RFLP analysis of gene regions, comparative genome hybridizations with S. cerevisiae DNA arrays, ploidy analysis and gene dose determination by quantitative real-time PCR. Genomic DNA hybridizations of w27, w46, SPG1691 and 441 hybrids were compared against the laboratory strain FY1679. Hybridizations were performed by triplicate in order to obtain the final CGH ratio.

Genomic Run On (GRO): determination of the nascent transcriptional rates in a spt16 mutant

Project description:We analyzed the effect of SPT16 on the transcription rates, mRNA stabilities and mRNA levels by doing GRO experiments in a thermosensitive spt16 point mutant (G132D) mutant at 35 ÂºC comparing with permisive temperature (30 ÂºC) and a wt treated in the same way. Cells (wt or spt16 mutant) were grown in SC-ura at 30 ÂºC to 0.25 OD600. At that time Î± factor was added and let to stand for 160 min in the same conditions. Then each sample (wt or mutant) was separated in two aliquots. One of them remain at 30ÂºC and the other was incubated at 35ÂºC. Both aliquots in the presence of Î± factor for 1h more. Finally, samples were processed for GRO experiment as described in Garcia-Marinez et al (2004). Three replicates of the whole experiment were done.
