| Title |
Serie I, HepG2 exposed to DEN for 24h, biological rep 3 |
| Sample type |
RNA |
| |
|
| Source name |
hepatocellular carcinoma cell line
|
| Organism |
Homo sapiens |
| Characteristics |
cell line: HepG2
compound, dose: DEN
time: 24h
|
| Treatment protocol |
When the HepG2 cells were 80% confluent, the medium was replaced with fresh medium containing either compound or solvent (0.5% DMSO, 0.5% EtOH or PBS)
|
| Growth protocol |
HepG2 cells were cultured in 6-well plates in the presence of minimal essential medium (MEM) supplemented with 1% non-essential amino acids, 1% sodium-pyruvate, 2% penicillin/streptomycin and 10% fetal bovine serum (FBS) (all from Gibco BRL, Breda, The Netherlands). The cells were incubated at 37 C and 5% CO2.
|
| Extracted molecule |
total RNA |
| Extraction protocol |
Trizol extraction was performed using the miRNAeasy kit from qiagen accoding to the manufacturer’s protocol
|
| Label |
biotin
|
| Label protocol |
Biotinylated cRNA were prepared according to the standard Affymetrix protocol from 250ng total RNA using the 3’ IVT express kit
|
| |
|
| Hybridization protocol |
12.5µg of cRNA were hybridized for 16 hr on 45°C on GeneChip Human Genome U133 Plus 2.0 Array, using Affymetrix® GeneChip® Fluidics Station 450 and the GeneChip Hybridization, Wash and Stain Kit
|
| Scan protocol |
Arrays were scanned using genechip scanner 3000 7G
|
| Data processing |
Obtained data sets were re-annotated to the MBNI Custom CDF-files (http://brainarray.mbni.med.umich.edu/Brainarray/Database/CustomCDF/genomic_curated_CDF.asp) (Dai et al., 2005) and RMA normalized (Irizarry et al., 2003) using the NuGOExpressionFileCreator, an enhanced version of the standard ExpressionFileCreator module that is present in GenePattern (De Groot et al., 2008). The resulting 17,788 probe sets represent 17,726 unique genes and 62 internal controls
