| Title |
AGS treated rep 1 |
| Sample type |
RNA |
| |
|
| Source name |
AGS cells treated with 10 μg/ml H. pylori LPS for 8h rep 1
|
| Organism |
Homo sapiens |
| Characteristics |
cell type: gastric epithelial cells
cell line: AGS
|
| Treatment protocol |
The morning of treatment, the cell culture medium was replaced with either fresh medium (untreated) or medium containing 10 μg/ml H. pylori lipopolysaccharide
|
| Growth protocol |
AGS cells were routinely maintained in nutrient mixture F-12 Ham (Sigma) supplemented with 10% foetal calf serum (Gibco), 2 mM L-glutamine (Sigma), 100 U/ml penicillin (Sigma) and 100 μg/ml streptomycin. The day before treatment, cells were seeded in 6-well plates at 1x106 cells/well.
|
| Extracted molecule |
total RNA |
| Extraction protocol |
8h post-stimulation, cells were harvested and RNA isolated using the Nucleospin RNAII kit (Machery Nagel) according to the manufacturer's instructions.
|
| Label |
biotin
|
| Label protocol |
Biotinylated cRNA were prepared according to the standard Affymetrix protocol from 5 μg total RNA (Expression Analysis Technical Manual, 2001, Affymetrix) using the Affymetrix IVT labeling kit.
|
| |
|
| Hybridization protocol |
Following fragmentation, cRNA was hybridized for 16 hr at 45C on Affymetrix U133 plus 2.0 genechips. GeneChips were washed and stained in the Automated fluidics 450 station.
|
| Scan protocol |
Genechips were scanned using the GeneChip 3000 7G scanner
|
| Description |
gene expression in H. pylori LPS-treated cells
|
| Data processing |
Scanned images, obtained using Affymetrix Software (MAS5), were normalized using robust multichip average (RMA) analysis with RMAExpress version 0.4.1.
