| Sample type |
SRA |

|
| Source name |
SLKK cells
|
| Organisms |
Homo sapiens; Human gammaherpesvirus 8 |
| Characteristics |
infection status: Chronically KSHV-infected
cell line: SLKK cells
|
| Growth protocol |
Human KS-derived SLK and SLKK cells (also known as SLK+rKSHV.219) (Herndier et al., 1994; Stürzl, Gaus, Dirks, Ganem, & Jochmann, 2013; Jeffrey Vieira & O’Hearn, 2004; Ziegelbauer, Sullivan, & Ganem, 2009) were maintained in Dulbecco’s Modified Eagle medium supplemented with 10% v/v fetal bovine serum and 1% Penicillin/streptomycin/glutamine solution. Additionally, KSHV-positive SLKK cells were periodically grown under selection with 10mg/mL puromycin to maintain the viral episome. Experiments were done in triplicate independent cell cultures maintained at 37°C in humidified 5% CO2.

| Extracted molecule |
polyA RNA |
| Extraction protocol |
Total RNA was extracted from cells using miRVana miRNA isolation kit (Ambion, Life Technologies) according to manufacturer instructions. RNA abundance and integrity were determined after isolation using a Nanodrop-ND-1000 spectrophotometer (Thermo Fisher Scientific) and an Agilent 2100 Bioanalyzer, respectively.
For mRNA-Seq: Total RNA of samples used for small RNA-Sequencing was treated with Turbo DNA-free DNase I and Dynabeads to deplete samples from the residual DNA and to isolate the polyadenylated mRNA transcriptome, respectively. PolyA+ RNA libraries were then prepared with the ScriptSeq v2 RNA-Seq kit (Epicentre). The final concentration and size distribution of the RNA libraries were measured by using a Nanodrop-ND-1000 spectrophotometer, and by running a DNA 100 chip on an Agilent 2100 Bioanalyzer. Finally, a total of 6 polyadenylated mRNA libraries (3 SLK and 3 SLKK samples) were sequenced using the Illumina HiSeq platform.

| Data processing |
For mRNA sequencing: Adapter sequences were trimmed using the Fastx toolkit. Reads were aligned against two target genomes, human (hg19) and KSHV (Genbank accession number NC_009333.1) using TopHat (Trapnell, Pachter, & Salzberg, 2009) to generate spliced alignments. Transcripts were assembled using Cufflinks and Cuffdiff (Trapnell et al., 2010) in order to reveal differentially expressed genes. Significant mRNA fold change was determined by an adjusted p-value lower than 0.05 based on the Benjamini and Hochberg multiple testing correction.
Genome_build: Human genome (hg19) and KSHV genome (Genbank accession number NC_009333.1)
