Sample GSM474503 Query DataSets for GSM474503
Status Public on Mar 01, 2010
Title human_LIMA_artery_patient5_bare_metal_cardiovascular_stent
Sample type RNA
 
Source name Human LIMA artery from patient 5, treatment: bare metal cardiovascular stent
Organism Homo sapiens
Characteristics gender: male
individual: patient 5
treatment: bare metal cardiovascular stent
Treatment protocol Thereafter, a bare metal stent (Express2, 2.5 x 16 mm stent, Boston Scientific Corporation, MA, USA) was implanted (1 min, 10 bar) into one of the three LIMA pieces and a paclitaxel-eluting stent (TAXUS Express2 2.5 x 16 mm stent, Boston Scientific Corporation, MA, USA) was implanted into another. The third part was left as unstented control. Forty-eight hours post stent implantation, the stents were removed and the LIMA samples snap frozen in liquid nitrogen.
Growth protocol As part of elective Coronary Artery Bypass Graft Surgery procedures performed at Lund University Hospital, Sweden, tissues containing parts of the LIMA from four coronary artery bypass graft (CABG) patients (68-73 year old males with stable angina and 3-vessel coronary atheroslerosis, two had hypertension, none were diabetic) were collected and stored in DMEM low glucose at 4C. Each LIMA (n=4) was dissected free of surrounding tissues, cut into three equal parts and incubated under tissue culture conditions in serum-free DMEM. All LIMA vessel segments were approximately 2 mm in diameter. The vessel segments were incubated for 24 h to induce quiescence.
Extracted molecule total RNA
Extraction protocol Tissues were homogenized in TRIzol and RNA purified as described in Amisten et al 2008 (PMID 17920662).
Label biotin
Label protocol Biotinylated cRNA were prepared according to the standard Affymetrix protocol from 1 ug total RNA (Expression Analysis Technical Manual, 2006, Affymetrix).
 
Hybridization protocol Following fragmentation, 10 ug of cRNA were hybridized for 16 hr at 45C on GeneChip Human Hu133Plus2.0 Array. GeneChips were washed and stained in the Affymetrix Fluidics Station 400.
Scan protocol GeneChips were scanned using the Hewlett-Packard GeneArray Scanner G2500A.
Description stable angina and 3-vessel coronary atheroslerosis
Data processing The data were analyzed with Expression Console ver.1 using Affymetrix default analysis settings followed by MAS5 as normalization method. The trimmed mean target intensity of each array was arbitrarily set to 100.
