| Title |
microRNA_IFNaIHH001_IFN_18h_3 |
| Sample type |
RNA |
| |
|
| Source name |
IHH cells, IFN treatment, 18 hours, replicate 3
|
| Organism |
Homo sapiens |
| Characteristics |
time: 18h
virus: IFN
replicate: 3
|
| Treatment protocol |
Treatments were initiated by replacing culture medium (containing 10% FBS) with fresh medium containing 500 U/ml of human interferon α (PBL Biosciences). Mock-treated cells were given normal culture medium only. Mock and treated cells were incubated at 37°C until sample collection time points.
|
| Growth protocol |
IHH cells were maintained in DMEM medium with 5% FCS with L-glut, Anti-Anti, Na Pyruvate, and Non-essential AA
|
| Extracted molecule |
total RNA |
| Extraction protocol |
RNA samples were collected by lysing cells directly in TRIzol. Lysates were scraped into a tube, vortexed thoroughly and directly frozen at -80°C.
|
| Label |
Cy3
|
| Label protocol |
Total RNA from each sample was amplified and transcribed into fluorescent cRNA using Agilent’s Quick Amp Labeling protocol (version 5.7, Agilent Technologies)
|
| |
|
| Hybridization protocol |
Sample labeling and array hybridization were performed according to the Agilent One-Color Microarray-Based Gene Expression Analysis protocol (Agilent Technology). Briefly, total RNA from each sample was linearly amplified and labeled with Cy3-UTP. The Labeled cRNAs were purified by RNeasy Mini Kit (Qiagen). The concentration and specific activity of the labeled cRNAs (pmol Cy3/μg cRNA) were measured by NanoDrop ND-1000. 1 μg of each labeled cRNA was fragmented by adding 11 μl 10 × Blocking Agent and 2.2 μl of 25×Fragmentation Buffer, then heated at 60 °C for 30 min, and finally 55 μl 2 × GE Hybridization buffer was added to dilute the labeled cRNA. 100μl of hybridization solution was dispensed into the gasket slide and assembled to the gene expression microarray slide. The slides were incubated for 17 hours at 65°C in an Agilent Hybridization Oven.
|
| Scan protocol |
The hybridized arrays were washed, fixed and scanned with using the Agilent DNA Microarray Scanner (part number G2505C).
|
| Data processing |
Scanned images were analyzed using Agilent Feature Extraction Software (v11.0.1.1). The limma package for R (available on Bioconductor) was used to perform background correction, quantile normalization (normalizeBetweenArrays), and summarization (avereps) to derive a single normalized intensity value per probe. Outlier samples were detected using PCA and by visual inspection of heatmaps, and all data was re-processed after removing outlier samples. All data processing for each of the biological replicates was performed independently of the other.
