| Title |
IMR90-Senescent-4 |
| Sample type |
RNA |
| |
|
| Source name |
IMR90 fibroblasts_90 population doublings
|
| Organism |
Homo sapiens |
| Characteristics |
cell line: IMR90
cell type: primary human fibroblasts
cell type: senescent
population doublings: 90
|
| Treatment protocol |
Senescence cells were maintained in dishes for 2 weeks to ensure growth termination. Senescence was determined by monitoring p16 upregulation, downregulation of cyclin genes, and by SA-beta galactosidase staining.
|
| Growth protocol |
IMR90 cells (obtained from Coriell Institute for Medical Research, Camden, NJ) were grown in standard tissue culture medium (DMEM with 10% FBS and 1% penicillin streptomycin) at 3% oxygen. For senescence studies, cells were replicatively passaged until growth ceased.
|
| Extracted molecule |
total RNA |
| Extraction protocol |
RNA was purified using Trizol extraction.
|
| Label |
biotin
|
| Label protocol |
Standard Affymetrix labeling, per manual.
|
| |
|
| Hybridization protocol |
Standard Affymetrix hybridization, per manual.
|
| Scan protocol |
Standard Affymetrix scanning, per manual.

| Description |
SAMPLE 9
|
| Data processing |
Data were imported into Partek and background-subtracted using GC-RMA. Data were quantile-normalized, median-polished, and subjected to a log2 transform.
