| Title |
Footprints from cells infected with HCMV for 72hr, pretreated with cycloheximide |
| Sample type |
SRA |
| |
|
| Source name |
Human fibroblasts infected with HCMV, cycloheximide, 72hr
|
| Organism |
Human betaherpesvirus 5 |
| Characteristics |
strain: Merlin
cell type: HCMV-infected human foreskin fibroblasts
drug pre-treatment: cycloheximide
infection duration: 72hr
|
| Extracted molecule |
total RNA |
| Extraction protocol |
Cells were lysed with 0.5% Triton, and the lysate was cleared by centrifugation, treated with RNase I for 45min and then loaded on a sucrose cushion. RNA was then isolated from cells using the acid:phenol extraction method.
Small RNA fragments were size selected via gel purification, dephosphorylated, ligated, and reverse transcribed. The resulting cDNA was circularized and PCR amplified.

| Description |
fp_chx_72hr_s1
Ribosome-protected mRNA.
|
| Data processing |
Prior to alignment, linker and polyA sequences were removed from the 3' ends of reads.
Bowtie v0.12.7 (allowing up to 2 mismatches) was used to perform the alignments. First, reads that aligned to human rRNA sequences were discarded.
All remaining reads were aligned to the HCMV virus genome (NC_006273.2).
Still-unaligned reads were aligned to 200bp sequences that spanned splice junctions.
Wig files were then generated by summing the numbers of reads obtained from each position in the viral genome. For this, each read was counted once. For the ribosome footprints samples, the calculated position of the ribosome P-site was used; for the mRNA samples, the 5' end of each read was used.
