cell line: hepatoma cell line SMMC-7721 genotype/variation: control
Treatment protocol
Each well of SMMC-7721 cells in six well plates was transfected by 10 nmol si-YWHAZ or the control siRNA-NC using Lipofectamine 3000 (Invitrogen, USA) according to the manufacturer’s instructions.
Growth protocol
SMMC-7721 cells were cultured in six well plates and incubated in a 37 °C, 5% CO2 humidified incubator
Extracted molecule
total RNA
Extraction protocol
48h after transient introduction of si-YWHAZ or siRNA-NC, total RNA was extracted and purified by RNeasy mini kit (Cat#74106, QIAGEN, GmBH, Germany) and RNase-Free DNase Set (Cat#79254, QIAGEN, GmBH, Germany).
Label
Cy3
Label protocol
Total RNA was amplified and labeled by Low Input Quick Amp Labeling Kit, One-Color (Cat.# 5190-2305, Agilent technologies, Santa Clara, CA, US), following the manufacturer’s instructions. Labeled cRNA were purified by RNeasy mini kit (Cat.# 74106, QIAGEN, GmBH, Germany).
Hybridization protocol
Each slide was hybridized with 600 ng Cy3-labeled cRNA using Gene Expression Hybridization Kit (Cat.# 5188-5242, Agilent technologies, Santa Clara, CA, US) in Hybridization Oven (Cat.# G2545A, Agilent technologies, Santa Clara, CA, US), according to the manufacturer’s instructions. After 17 hours hybridization, slides were washed in staining dishes (Cat.# 121, Thermo Shandon, Waltham, MA, US) with Gene Expression Wash Buffer Kit(Cat.# 5188-5327, Agilent technologies, Santa Clara, CA, US), followed the manufacturer’s instructions
Scan protocol
Slides were scanned by Agilent Microarray Scanner (Cat#G2565CA, Agilent technologies, Santa Clara, CA, US) with default settings, Dye channel: Green, Scan resolution=3μm, PMT 100%, 20bit.
Description
Gene expression after transfected with siRNA-NC
Data processing
Data were extracted with Feature Extraction software 10.7 (Agilent technologies, Santa Clara, CA, US). Raw data were normalized by Quantile algorithm, limma packages in R.
