| Title |
BEAS-2B_rep_1 |
| Sample type |
RNA |
| |
|
| Source name |
parental cell line used for As and Ni exposures
|
| Organism |
Homo sapiens |
| Characteristics |
cell line background: BEAS-2B
background cell type: immortalized human bronchial epithelial cell
cell type: parental cell line used for As and Ni exposures
|
| Treatment protocol |
Cells were treated with an aqueous filter-sterlized solution of metals at the concentrations and days indicated prior to seeding in soft agar; metal was removed before seeding in soft agar and for the remainder of the experiment.
|
| Growth protocol |
cell were grown under standard laboratory conditions in DMEM supplemented with 10% FBS and 1% PenStrep; a single cell suspension of 5,000 cells per 9.6 square cm was seeded in soft agar at a concentration of 0.35%
|
| Extracted molecule |
total RNA |
| Extraction protocol |
Total RNA was extracted using Trizol (Invitrogen) according to the manufacturer’s protocol and purified using RNeasy Plus Micro Kit (Qiagen).
|
| Label |
biotin
|
| Label protocol |
The cDNA probes were synthesized using the WT Expression Kit for Affymetrix Whole Transcript Expression Arrays (Ambion), fragmented, and labeled using Affymetrix Whole Transcript Terminal Labeling Kit (Affymetrix).
|
| |
|
| Hybridization protocol |
cRNA generated by the labeling procedure was hybridized for 16 hr to the Affymetrix array according to the manufacturer's manual. Genechips were processed using protocol FS450_0007 for Genechip® fluidics station 450.
|
| Scan protocol |
Affymetrix GeneArray scanner 7G
|
| Description |
P-1
|
| Data processing |
Feature intensity was extracted by GeneChip Operating System as CEL files; data from cel files were batch normalized in R using the COMBAT package. The probe-level analysis of the batch-normalized data was done by the RMA-16 algorithm using GeneSpring GX11.5 program.
