| Title |
set1_calu3_moi01_48hpi_sRNA |
| Sample type |
SRA |
| |
|
| Source name |
Epithelial cell in human lung adenocarcinoma
|
| Organisms |
Homo sapiens; Severe acute respiratory syndrome coronavirus 2 |
| Characteristics |
cell line: Calu-3
treatment: infected, 48hpi
concentration: MOI 0.1
assay: small RNA-seq
biorep: rep1
|
| Treatment protocol |
Prior to lysis, cells were seeded in 100mm dishes, and treated cells were infected with SARS-CoV-2 (MOI = 0.1). At 48 hpi, both mock and treated dishes for RPF, QTI, and mRNA-seq were treated with either 100 μg/ml cycloheximide (CHX) or 2 µg/ml harringtonine (Harr) for 10 min.
|
| Growth protocol |
Calu-3 cells were cultured in DMEM with 10% FBS and 1% penicillin/streptomycin
|
| Extracted molecule |
total RNA |
| Extraction protocol |
For sRNA-seq, RNA was extracted using Trizol. For rest, cells were washed with PBS then lysed with lysis buffer (10 mM Tris-HCl (pH 7.4), 5 mM MgCl2, 100 mM KCl, 1% Triton X-100, 100 μg/ml CHX, 1 mM dithiothreitol, 0.2 U/μl RiboLock RNase inhibitor, and 1 × EDTA-free protease inhibitor cocktail). For RPF-seq and QTI-seq, lysates were treated with RNase I and ribosome protected fragments were isolated using illustra MicroSpin S-400 HR Columns (GE Healthcare).
All of the libraries (mRNA-seq, RPF-seq, QTI-seq, and sRNA-seq) were constructed following the Illumina Truseq small RNA library preparation protocol (TruSeq Small RNA Library Prep Guide, Part # 15004197 Rev. G)

| Data processing |
1. Base-calling by RTA(Real Time Analaysis) software within HiSeq 2500 (mRNA-Seq) or HiSeq 2000 (sRNA-Seq)
2. Quality trimming by the highest scoring path algorithm (hsptrim-1.2.6)
3. Adapter trimming by cutadapt-1.2.1
4. Remove sequencing artifacts by fastx_artifacts_filter of fastx_toolkit
5. Remove ncRNA-derived reads by Bowtie2 alignment
6. Remove mycoplasma-derived reads by Bowtie2 alignment
7. Alignment of filtered reads to SARS-CoV-2 and host genome by STAR (mRNA-seq, RPF-seq, QTI-seq) or Bowtie2 (sRNA-seq)
8. Calculation of log2(expression fold changes) and differential expression for human genes by DESeq2
Genome_build: NC_045512.2 (SARS-CoV-2)
Genome_build: hg38 (GRCh38)
Genome_build: chlSab2
Supplementary_files_format_and_content: bigwig (coverage depth), tab-delimited text files, containing gene expression levels (average RPKM within replicates), log2(expression fold changes), and statistical significances calculated by DESeq2.
