Sample GSM3421730 Query DataSets for GSM3421730
Status Public on Jul 28, 2019
Title Breast adenocarcinoma cell line MCF7 – Long Term Estrogen Deprived (LTED) – rep3
Sample type RNA
 
Source name Breast adenocarcinoma
Organism Homo sapiens
Characteristics treatment: Long Term Estrogen Deprived MCF7 cells
cell type: LTED
Treatment protocol MCF7- and LTED cells were maintained in sterol-deprived medium in phenol red–free RPMI1640 medium containing 10% dextran charcoal-stripped (DCC) FBS and 2 mmol/L glutamine (DCC medium). MCF7+ cells were grown as MCF7+ and LTED in the presence of 1 nM 17β-oestradiol (E2, Sigma).
Growth protocol MCF7 and LTED human breast cancer cells were obtained from ATCC and cultured in phenol free-red RPMI 1640 medium supplemented with 10% foetal bovine serum and 2 mmol/L glutamine. Cells were short tandem repeat tested, amplified, stocked, routinely subjected to mycoplasma testing and once thawed were kept in culture for a maximum of 20 passages.
Extracted molecule total RNA
Extraction protocol Total RNA (including microRNA) was extracted using miRNeasy (Qiagen) according to the manufacturer’s instructions.
Label Cy3
Label protocol RNA labeling was performed in accordance to manufacturer’s indications.
 
Hybridization protocol RNA hybridization was performed in accordance to manufacturer’s indications.
Scan protocol Arrays were scanned with Agilent Technologies Scanner G2505C. Numerical raw values were obtained using Feature Extraction 10.7.3.1 software (Agilent Technologies). Grid: 028004_D_F_20140813. Protocol: GE1_107_Sep09
Description Gene expression of Long Term Estrogen Deprived MCF7 cells (LTED)
Data processing Data were normalized and analyzed using GeneSpring GX v.14.8 software (Agilent Technologies). Data transformation was applied to set all the negative raw values at 1.0, then the quantile normalization was applied. A filter on low gene expression was used to keep only the probes expressed in at least one sample.
