| Title |
mRNASeq_mock_32hr_runs1-3 |
| Sample type |
SRA |
| |
|
| Source name |
HeLa
|
| Organism |
Homo sapiens |
| Characteristics |
transfection: mock
time: 32hr
|
| Treatment protocol |
All samples were treated with cycloheximide (100 ug/ml) for 8 min just before harvesting.
|
| Extracted molecule |
total RNA |
| Extraction protocol |
mRNA-Seq: poly(A)-selected RNA was randomly fragmented by partial alkaline hydrolysis. Size-selected RNA fragments (25-45 nt) were used for library preparation.
Ribosome profiling: Cell extracts were digested with RNase I for 30 min at room temperature, and monosomes were purified by sucrose gradient centrifugation. Size-selected RNA fragments (~27-33 nt) were used for library preparation.
Library preparation: Libraries were prepared as in Grimson et al, 2008 (GSE12578) but with the following modifications. Because RNase I-digestion and alkaline-fragmentation products terminate with a 5'-hydroxyl and a 3'-phosphate, they were 3'-dephosphorylated before ligation to the 3' adaptor. Gel-purified 3'-ligation products were then 5'-phosphorylated before the 5'-ligation step.

| Data processing |
Reads were mapped to the indicated genome build (hg18) using the Bowtie short-read mapping program. For each sample, uniquely-mapping reads from multiple runs were combined to generate the processed data file.
