ABSTRACT: Within a GRO experiment, samples for Transcription rate (TR) analysis were taken at 0, 4, 11, 16, 26 and 40 minutes after heat stress (from 25ºC to 37ºC) and subjected to run-on. Analysis was done in filters also used for RA analysis of aliquots from the same cultures.

Analysis was done in filters also used for RA analysis of aliquots from the same cultures. The analysis includes 3 repeats of stress treatment of the W3030-1a strain. The same times were used for sampling in each repeat of the experiment. A single genomic DNA hybridization on every one of the filters is used for normalization between gene probes.

Project description:Transcription rate (TR) analysis of W303-1a yeast strain growing in exponential phase in YPD subjected to terbutyl stress Keywords: time course Transcription rate analysis by means of GRO of three independent replicates the yeast strain growing in exponential phase. Each time point replicate has been hybridized on a different macroarray (F5-F10). A single DNA genomic hybridization from the same labeling reaction was done on the same macroarrays for normalization.

Project description:This SuperSeries is composed of the following subset Series: GSE24483: TR heat-shock GSE24484: RA heat-shock Refer to individual Series
Project description:The effect of Kap120 deletion at transcriptional level was investigated by GRO analysis of the transcription rates (TR) and mRNA levels (RA) genome-wide. mRNA stabilities can be calculated as RA /TR for each gene in all samples.
Project description:Heat shock response (HSR) is a cellular defense mechanism against various stresses. Both heat shock and proteasome inhibitor MG132 cause the induction of heat shock proteins, a distinct feature of HSR. To better understand the molecular basis of HSR, we subjected the mouse fibrosarcoma cell line, RIF-1, and its thermotolerant variant, TR-RIF-1 cells, to heat shock and MG132. We compared mRNA expressions using microarray analysis during recovery after heat shock and MG132 treatment. This study led us to group the 3,245 up-regulated genes by heat shock and MG132 into three families: genes regulated 1) by both heat shock and MG132 (e.g. chaperones); 2) by heat shock (e.g. DNA-binding proteins including histones); and 3) by MG132 (e.g. innate immunity and defense-related molecules). RIF-1 and TR cells were heat shock treated or MG132 treated and harvested after various times of recovery. mRNA expressions were compared to untreated samples. Biological replication was done.
