Title |
Baseline.2 (II) |
Sample type |
RNA |
|
|
Source name |
Aortic vascular smooth muscle cells_baseline
|
Organism |
Mus musculus |
Characteristics |
strain: C57BL/6 age: 8 weeks-old stimulus: none cell type: primary aortic smooth muscle cells (SMCs)
|
Treatment protocol |
Cells were either harvested at baseline or treated with 10 μg/mL Cholesterol:methyl-β-cyclodextrin complex (1:6 molar ratio) for 72 h and then harvested, or treated with cholesterol for 72 h and then treated with 100 μg/mL HDL for an additional 72 h and then harvested.
|
Growth protocol |
Mouse aortic VSMCs were isolated from thoracic aortas of 8 week-old C57BL/6 mice (as described in Rong et al., Proc Nat Acad Sci USA, v100, pp13531–13536, 2003) and subconfluent cell preparations (≤ five passages) were grown in DMEM containing 10% FBS, 100 units/mL penicillin, and 100 μg/mL streptomycin, and incubated at 37 °C with 5% CO2 / 95% air.
|
Extracted molecule |
total RNA |
Extraction protocol |
Total RNA was isolated using TRIzol (Invitrogen). RNA quality was analyzed with an Agilent Bioanalyzer.
|
Label |
biotin
|
Label protocol |
RNA samples were reverse transcribed to cDNA, transcribed to obtain labeled aRNA, purified, and fragmented using the GeneChip 3’ IVT Express kit.
|
|
|
Hybridization protocol |
Labeled aRNA was hybridized onto the GeneChip® Mouse Genome 430 2.0 using the GeneChip Hybridization Oven 640, and the GeneChip was stained in a GeneChip Fluidics Station 450 with streptavidin-phycoerythrin conjugate.
|
Scan protocol |
GeneChips were scanned using the Affymetrix GeneChip Scanner 3000.

Description |
Analysis (II)
|
Data processing |
Probe-level intensities for all six samples (baseline, cholesterol-treated, and HDL-recovered) were background-adjusted and normalized using the Robust Multichip Average procedure. Probe-level log2 intensities were combined into probesets using probe-to-probeset mappings from the University of Michigan CustomCDF project version 13, based on Ensembl Gene identifiers (release 58).
