Sample GSM1924804 Query DataSets for GSM1924804
Status Public on Dec 11, 2015
Title Mock 24 h replicate 3
Sample type SRA
 
Source name cell culture infection model
Organism Homo sapiens
Characteristics human cell line: HeLa-S3 (ATCC CCL-2.2)
organism: human cell line HeLa-S3
Treatment protocol Infection samples: In vitro infection was carried out following the protocol of (Schulte et al., 2011) with the indicated Salmonella Typhimurium (SL1344) strain in 6-well format. At the indicated time point post-infection, cells were fixed with RNAlater (Qiagen) and sorted for invaded (GFP+) and non-infected (GFP-) host cells using a FACSAria III device (BD). Total RNA from the sorted cells was extracted following the miRvana protocol (Ambion). "0 h" refers to RNA extracted from mixed lysates of extracellular Salmonella and host cells.
Growth protocol HeLa-S3 cells were cultured according the guidelines provided by the ENCODE consortium (http://genome.ucsc.edu/encode/protocols/cell/human/Stam_15_protocols.pdf). Cells were grown in DMEM (Gibco) supplemented with 10% fetal calf serum (FCS; Biochrom), 2 mM L-glutamine (Gibco) and 1 mM sodium pyruvate (Gibco) in T-75 flasks (Corning) in a 5% CO2, humidified atmosphere at 37°C. All further cell lines used in this study (THP-1, CaCo-2, AGS, HEK, MEF and RAW264.7) were cultured in RPMI (Gibco) supplemented with 10% FCS, 2 mM L-glutamine, 1 mM sodium pyruvate in a 5% CO2, humidified atmosphere at 37°C.For the differentiation of bone marrow derived macrophages the marrow of femur and tibia was isolated from 8-12 week old female C57BL/6 wild-type mice and stored in RPMI supplemented with 10% FCS. The cell suspension was centrifuged for 5 min at 250 g and the leukocyte pellet was resuspended in differentiation medium consisting of X-vivo-15 medium (Lonza) supplemented with 10% FCS and 10% L929 conditioned DMEM medium (same composition as above). Cells were cultured for 3 days at 3*106 cells per 10 mL in a T-75 flask. At day 3 another 3 mL of differentiation medium were added and cells were further cultured until day 5. Successful macrophage differentiation was validated by microscopy on day 5 upon which the cells were disattached using a rubber scraper (Sarstedt) and seeded into 6-well plates at 105 cells per well in fresh differentiation medium. Infection was carried out on day 7 as described below.
Extracted molecule total RNA
Extraction protocol miRvana kit for total RNA (Ambion) or TRIzol (Invitrogen) as indicated
The total RNA samples were first fragmented using ultrasound (4 pulses of 30 s each). Then, RNAs <20 nt were removed using the Agencourt RNAClean XP kit (Beckman Coulter Genomics). This was followed by a dephosphorylation with Antarctic Phosphatase (AP, NEB) and re-phosphorylation with T4 Polynucleotide Kinase (PNK, NEB). Oligonucleotide adapters were ligated to the 5' and 3' ends of the RNA samples. First-strand cDNA synthesis was performed using M-MLV reverse transcriptase and the 3’ adapter as primer. The resulting cDNAs were amplified with PCR using a high fidelity DNA polymerase. The cDNA was purified using the Agencourt AMPure XP kit (Beckman Coulter Genomics) and was analyzed by capillary electrophoresis. For Illumina NextSeq sequencing, the samples were pooled in approximately equimolar amounts. An aliquot of the size fractionated pool was analyzed by capillary electrophoresis.
