| Title |
MDA::ER::pcDNA_EtOH_1 |
| Sample type |
RNA |
| |
|
| Source name |
MDA::ER::pcDNA cells treated for 4h with 0.1% ethanol (vehicle control)
|
| Organism |
Homo sapiens |
| Characteristics |
gender: female
cell type: breast cancer cells
er status: Positive
integrated vectors: pCDNA3.1-Hygro-ER + pcDNA6/TR + empty pcDNA4/TO
|
| Treatment protocol |
Cells were plated at 2x106 cells per 9cmØ dishes in DMEM/2.5% FCS (complemented with 0.8 mg/ml hygromycin, 5 µg/ml Blasticidin and 75 µg/ml Zeocin) for 16h. Following two washes with PBS, cells were then cultivated for 3 days in DMEM/0.5% charcoal-stripped serum (BioWest) complemented with all antibiotics. Confluent cells were then treated with Estradiol (E2, Sigma) at a final concentration of 10-8 M for 4h or with equivalent amounts of ethanol vehicle (0.1%).
|
| Growth protocol |
Cells were maintained in DMEM (Sigma) supplemented with 5% fetal calf serum (FCS, BioWest) and antibiotics (Roche) at 37°C under 5% CO2. Media was complemented with 0.8 mg/ml Hygromycin (Calbiochem), 5 µg/ml Blasticidin (Invitrogen) and 75 µg/ml Zeocin (Invitrogen) for continuous selection of pCDNA3.1-Hygro-ER, pcDNA6/TR and empty pcDNA4/TO or pcDNA4/FOXA1 vectors, respectively.
|
| Extracted molecule |
total RNA |
| Extraction protocol |
Total RNA was extracted using the RNeasy Mini kit (Qiagen) with homogenization facilitated by QIAShredders (Qiagen). Integrity and purity of the RNAs were controlled on an Agilent Bioanalyzer using the RNA 6000 Nano Assay (Agilent). Ten micrograms of selected samples exhibiting a RIN >9.8 were then subjected to cDNA synthesis using the Superscript Double-Stranded cDNA Synthesis Kit (Invitrogen) and 50 pmol random hexamers. cDNAs were then treated for 10 min at 37°C with 5 μg RNaseA (Invitrogen), purified through a phenol:chloroform:isoamyl alcohol extraction on Phase Lock light gels (Fisher Scientific) and then precipitated.

| Description |
This sample is of MDA::ER::pcDNA cells (MDA-MB231 cells engineered to express the estrogen receptor and expressing the Tet Repressor) treated with ethanol (vehicle control) for 4h. First of the three independent replicates used in this experiment, each constituted by a pool of three separate cultures.
|
| Data processing |
Raw data (.pair) were subjected to the RMA algorithm (Robust Multi-Array Analysis; Irizarry et al. Biostatistics 4(2):249) with quantile settings (Bolstad et al. Bioinformatics 19(2):185) for background correction and normalization, as implemented within the ArrayStar software package (DNAstar, Inc.).
