group: treatment perturbagen: Liquiritin cell line: breast cancer cell line MCF7 duration: 12 h
Treatment protocol
The MCF7 cells were treated by 102 molecules at 10μM or 1μM, DMSO, and 10μM mixture of four compounds (1:1:1:1) for 12h.
Growth protocol
The MCF7 cells were cultured in MEM/EBSS supplemented with 10% fetal bovine serum, 1mmol/L sodium pyruvate, 0.1mmol/L MEM non-essential amino acids, 100 unit/mL penicillin, and 100 mg/mL streptomycin in a incubator containing 5% CO2 at 37℃.
Extracted molecule
total RNA
Extraction protocol
Total RNA was extracted using TRIZOL Reagent (Cat#15596-018，Life technologies, Carlsbad, CA, US)following the manufacturer’s instructions and checked for a RIN number to inspect RNA integrity by an Agilent Bioanalyzer 2100 (Agilent technologies, Santa Clara, CA, US).Qualified total RNA was further purified by RNeasy micro kit (Cat#74004, QIAGEN, GmBH, Germany) and RNase-Free DNase Set (Cat#79254, QIAGEN, GmBH, Germany).
Label
biotin
Label protocol
Total RNA were amplified, labeled and purified by using GeneChip 3’IVT Express Kit (Cat#901229, Affymetrix, Santa Clara, CA, US) followed the manufacturer’s instructions to obtain biotin labeled cRNA.
Hybridization protocol
Array hybridization and wash was performed using GeneChip® Hybridization, Wash and Stain Kit (Cat#900720, Affymetrix, Santa Clara, CA, US)in Hybridization Oven 645 (Cat#00-0331-220V, Affymetrix, Santa Clara, CA, US)and Fluidics Station 450 (Cat#00-0079, Affymetrix, Santa Clara, CA, US) followed the manufacturer’s instructions.
Scan protocol
Slides were scanned by GeneChip® Scanner 3000 (Cat#00-00212, Affymetrix, Santa Clara, CA, US)
Description
