Title Affinity purification of ribosomes and associated RNAs from stress-treated cells
Organism Saccharomyces cerevisiae
Experiment type Expression profiling by array
Other
Summary In this study, we systematically identified ribosome associated RNAs. To identify ribosome associated RNAs, C-terminal ZZ-tagged Rpl16a, expressed under control of its native promoter, was affinity purified from whole cell extracts of cultures grown to mid-log phase. Extracts were incubated with immunoglobulin G (IgG) coupled microbeads, washed, and ribosomes were eluted by tobacco etch virus (TEV) protease treatment. To analyze how changes in steady-state mRNA levels (= transcriptome) are related to changes of respective messages in the translatome, total RNA and ribosome associated RNA from stress-treated and untreated cells were analyzed with yeast cDNA microarrays. To achieve this, fluorescently labeled (Cy5) cDNA was prepared from total RNA isolated from yeast cell extracts and from affinity-purified ribosomes, and each sample was mixed with differentially labeled (Cy3) cDNA prepared from a common reference RNA pool, and competitively hybridized on yeast cDNA microarrays. We performed five independent experiments with untreated cells grown in minimal medium (t=0 reference) and three or more independent biological replicates of treated cells. Altogether, we sampled the cell's response to five different "stress treatments" that were applied for relatively short periods of time (10 or 20 minutes) to avoid secondary effects triggered by transcriptional adaption.
A stimulus or stress experiment design type is where that tests response of an organism(s) to stress/stimulus. e.g. osmotic stress, behavioral treatment
