GSE134888: Transcriptome wide analysis of translation efficiency in MCF7 cells using polysome profiling with and without eIF4A inhibition by hippuristanol treatment

Bulk RNA sequencing

To identify mRNAs that are most translationally repressed following eIF4A inhibition and those that are relatively insensitive, polysome profiling was carried with and without eIF4A inhibition by hippuristanol treatment. Polysomal, sub-polysomal and total RNA was sequenced and we used a Bayesian model to identify mRNAs that with greatest confidence had shifted from the polysomal into the sub-polysomal fractions, from the sub-polysomal into the polysomal fractionsand those mRNAs that did not change in their polysomal to sub-polysomal ratio, following hipp treatment, which were termed eIF4A-dependent, eIF4A-antidependent and eIF4A-independent mRNAs respectively SOURCE: Joseph,Alexander,Waldron (joe.waldron@hotmail.co.uk, J.Waldron@beatson.gla.ac.uk) - Beatson Institute for Cancer Research
