Title |
transcriptional profiling of CD133+ cells in coronary artery disease, SG-6B |
Sample type |
RNA |
|
|
Source name |
CAD patient, after 3 months of exercise
|
Organism |
Homo sapiens |
Characteristics |
tissue: peripheral blood cell type: CD133+ cells disease: coronary artery disease treatment: 3 months of exercise
|
Treatment protocol |
Cardivovascular examination and baseline testing were performed after an overnight fast (except for water). Symptom-limited treadmill exercise was performed using the modified Bruce protocal. Healthy subjects of similar age and sex distribution were recruited for the study to serve as controls for baseline analysis.
|
Growth protocol |
CAD patients enrolled in a cardiac rehabilitation program consisting of 36 sessions of 60 minutes each, spaced over 3 months. Medical management was stable for at least a month prior to program participation and all patients were maintained on medications throughout the study as prescribed without change in preparation or dose.
|
Extracted molecule |
total RNA |
Extraction protocol |
32 ml of PB was used for isolation of CD133+ cells using fluorescence-actived cell sorting. Total RNA was extracted from CD133+ cells with an RNAqueous micro RNA isolation kit (Ambion, Austin, TX). Cells were lysed in buffer containing guanidinium thiocyanate.
|
Label |
biotin
|
Label protocol |
Biotin labeled with Affymetrix's IVT labeling kits (Affymetrix, Santa Clara, CA).
|
|
|
Hybridization protocol |
Fragmented RNA was assessed for relative length on Agilent 2100 bioanalyzer and hybridized to Affymetrix HG-U133 Plus 2.0 chips for 16 hours.
|
Scan protocol |
Affymetrix GeneChip scanner.
|
Description |
CD133+ cells sorted from PB. SG-6B
|
Data processing |
Intensities were pre-processed with MAS5.0, and further processed with variance stablization transformation ('S10'). 26,123 probesets present in at least 2 out of 14 chips (4 healthy controls and 10 CAD baselines) were S10 transformed and analyzed.
