At each time point, we harvested the cells directly into 1 mL of Trizol® (life technologies, CA, USA) and extracted total RNA according to the manufacturer's recommended protocol. We performed two rounds of poly-A selection and fragmented 100 ng of the resulting mRNA into approximately 200 bases fragments. We prepared cDNA and the second strand. We prepared Illumina multiplexed libraries. We prepared 14 individual libraries separately (one from each sample) and added a unique barcode to each library at the final step of PCR amplification. We pooled equal amounts of DNA from each library and sequenced one pool per lane of a flow cell on Illumina Genome Analyzer II using the manufacturer's recommended pipeline (versions 1.2 and 1.3, read length = 50 bases)
