| Title |
gall bladder epithelium_WT infected_replicate 2_vs_ΔcdtB infected_replicate 2 |
| Sample type |
RNA |
| |
|
| Channel 1 |
| Source name |
ΔcdtB infected, replicate 2
|
| Organism |
Homo sapiens |
| Characteristics |
tissue: gall bladder
cell type: epithelium
treatment: infected
bacteria_strain: S. paratyphi A, ΔcdtB
culture type: 2D
replicate: P2
|
| Treatment protocol |
Organoids were harvested 4 or 14 days (for early and differentiated organoids, respectively) after seeding. For infection experiments, 2D primary cells infected with /Salmonella/ paratyphi A were harvested 5 days post infection, FACS sorted based on the /Salmonella/ mCherry fluorescence to get 3x10^5 infected cells for RNA extraction.
|
| Growth protocol |
Human gall bladder epithelial cells were derived from patients that underwent cholecystectomy, stored in ice-cold PBS for up to 2 hours and the tissue was washed with PBS from the residual bile and mucus and it was incubated at 37°C with the mucosal side facing a solution of 0.2% collagenase type IV. The mucosa was abraded thoroughly with the end of a glass microscope slide held at an angle of 45°every 5 minutes, for 4 times. The isolated cells were passed through a cell strainer with 70μm pores, spun down and 1 to 3 million cells were resuspended in a drop of 50μl matrigel. The polymerized matrigel drop was then supplemented with a medium based on Advanced/DMEM F12 (Invitrogen). The medium was changed twice a week. Every 7 to 10 days the organoids were spit with a ratio 1 to 3-4 by treating with Trypsin, then passing them 10 times through a heat-narrowed Pasteur pipet.

|
| Label |
Cy3
|

| Label |
Cy5
|
| Label protocol |
RNA was labeled with the Low Input Quick Amp Labeling Kit (Agilent Technologies) according to manufacturer’s instructions.
|

|
| |
| Hybridization protocol |
After precipitation, purification and quantification, labeled samples were hybridized according to the supplier's protocol (Agilent Technologies).
|
| Scan protocol |
Scanning of microarrays was performed with 3µm resolution using a G2565CA high resolution laser microarray scanner (Agilent Technologies).
|
| Data processing |
Microarray image data were extracted and analyzed with the Image Analysis / Feature Extraction software G2567AA (Version A.10.10.1, Agilent Technologies) using default settings and the GE1_1105_Oct12 extraction protocol. The extracted dual-color raw data txt files were further analyzed using R and the associated BioConductor package limma. Agilent FE software processed green and red signals were extracted and within-array normalized using method LOESS followed by averaging of duplicated probes was applied.
