| Sample type |
RNA |

|
| Source name |
healthy_monocytes_autologous_serum_IFNa2b_1hr
|
| Organism |
Homo sapiens |
| Characteristics |
disease state: healthy
cell type: monocyte
treatment: autologous serum IFNa2b
time: 1hr
|
| Treatment protocol |
incubated with 20% autologous serum alone or in the presence of 1000 U/ml of IFNα2b (Schering Plough, Kenilworth, NJ) in 6-well plates at a concentration of 106 monocytes per well in 3 ml of media. After incubation for one hour at 37 ⁰C, cells were harvested and RNA was extracted. Identical experiments were done after the following incubation time points: six hours, twenty four hours, two days, and three days.
|
| Growth protocol |
none
|
| Extracted molecule |
total RNA |
| Extraction protocol |
RNA was extracted using either the RNeasy® Mini Kit (Qiagen, Valencia, CA), if >5x105 were recovered, or PicoPureTM RNA Isolation Kit (Molecular Devices Corporation, Sunnyvale, CA) when <5x105 cells were recovered
|
| Label |
biotin
|
| Label protocol |
RNA was labeled using the GeneChip® Two-Cycle Target Labeling kit (Affimetrix, Santa Clara, CA) following the manufacturer’s recommended procedures
|
| |
|
| Hybridization protocol |
cRNA was fragmented and hybridized to the HG-U133A & HG-U133B Affymetrix GeneChip® arrays that contain 45,000 probe sets at 45 ⁰C for 16 hours
|
| Scan protocol |
GeneChip arrays were washed, stained, and scanned according to protocols described in the GeneChip Expression Analysis Technical Manual (Affymetrix, Santa Clara, CA)
|
| Data processing |
To analyze the data from monocytes from untreated and treated SLE patients, 5 samples in each data set were used for final analysis, and compared to 5 samples from healthy donors. Data were normalized to this set of healthy controls. For each set of experiments, unsupervised clustering of samples was performed using the list of genes present in at least one sample to rule out technical variability. For supervised analysis, an Affymetrix flag call of ‘present’ in 3 out of 5 samples from each cohort was used to designate the filter for a reliable intensity measurement from each individual gene chip. These two lists combined were used as a quality control measure for class comparison, which was performed using a non- parametric ranking statistical analysis test (Mann Whitney) as well as a 2-fold difference in the average normalized value of healthy to test set.
