| Source name |
UPR-induced S2 cells, T1 RNA-seq
|
| Organism |
Drosophila melanogaster |
| Characteristics |
cell type: S2 cell
time: T1 (1 hour)
|
| Extracted molecule |
total RNA |
| Extraction protocol |
[RNA-seq] 10^7 Drosophila S2 cells were harvested on ice, washed in cold PBS and their RNA was extracted using the RNeasy Kit (Qiagen) with on column DNAse digestion according to the manufacturer’s protocol. Ribosomal RNA was depleted from the total RNA (5ug) by using the RiboZero gold magnetic kit (Epicentre/Illumina) according to manufacturer’s instructions. cDNA was generated with the TruSeq non–stranded kit (Illumina) according to manufacturer’s instructions

| Data processing |
MNase-seq, ATAC-seq and ChIP-seq: The sequenced paired-end reads were mapped to dm3 genome using Bowtie aligner v. 0.12.939. Only uniquely mapped reads with no more than two mismatches were retained. The reads with the insert sizes less than 50 bp or larger than 500 bp were filtered out. Genomic positions with the numbers of mapped tags above the significance threshold of z-score = 7 were identified as anomalous, and the tags mapped to such positions were discarded. Read frequencies were computed in 300-bp non-overlapping bins in the case of fly data and in 500-bp bins in the case of human data for each titration point independently. The read frequencies were normalized by the corresponding library sizes to represent values per one million of mapped reads. To facilitate the comparison of the results between different genomes, the frequencies were additionally scaled by the factors representing ratios between the corresponding genome size and 100 Mb.
RNA-seq: Tags were aligned using Tophat software package with default parameters. RNA-Seq tag frequencies were normalized for GC-content using bioconductor package EDASeq and then the expression estimates for each gene were obtained using bioconductor package DESeq.
