Sample GSM2578998 Query DataSets for GSM2578998
Status Public on Apr 05, 2018
Title RNASeq_Htz1_OE_caffeine-120-min_rep2
Sample type SRA
 
Source name Saccharomyces cerevisiae cells grown in caffeine
Organism Saccharomyces cerevisiae
Characteristics genotype: YDS2 + bar1::HIS htz1::TRP + p[HTZ1]-2u-URA
Growth protocol Cells were grown to mid-log phase in drug-free medium (SD-Ura) and then caffeine (Sigma) was added to 10 mM. MG-132 (Merck) 150 mM treatment was carried out in medium containing 0.006% SDS to facilitate drug uptake. For histone deacetylase inhibition, 75mM VPA was added to cells for 45 minutes.
Extracted molecule total RNA
Extraction protocol Cultures were crosslinked with 1% (v/v) formaldehyde, quenched with glycine, and cells were lysed with beads in a FastPrep-24 (MP Biomedicals) cell homogeniser. Sonicated, clarified extracts were immunoprecipitated with anti-Htz1 antibodies before washing and DNA extraction, or were used directly to prepare input DNA.
Illumina TruSeq ChIP Sample Prep Kit were used for ChIP-seq library preparation. RNA library was prepared using the Illumina TruSeq stranded mRNA sample preparation kit.
 
Library strategy RNA-Seq
Library source transcriptomic
Library selection cDNA
Instrument model Illumina HiSeq 2000
 
Data processing ChIP-seq and RNA-seq reads were mapped to the S. cerevisiae genome assembly sacCer1 using Bowtie2 and Tophat2 respectively, allowing up to 2 mismatches per sequence and no ambiguously mapped reads.
Normalisation for ChIP-seq (wild-type (WT) and 4KR samples) was performed based on the assumption that the genomic background is constant over the time course. Background signal was set to 1.2 standard deviations above the mean of the ChIP:input ratios and then subtracted from the ChIP-seq signal.
