Sample GSM63084 Query DataSets for GSM63084
Status Public on Mar 16, 2006
Title HSVMC_HighK+_rep2
Sample type RNA
 
Source name cerebral artery
Organism Homo sapiens
Characteristics Gender: Male
Age: 45 years
Tissue: human cerebral artery
Biomaterial provider Human cerebral vascular smooth muscle cells (hcVSMCs) (passages 2-4) were obtained from human cerebral artery explants (IRB# CHRMS 01-195; informed consent) and maintained in SMGM2 (Clontech, Palo Alto, CA
Treatment protocol Early passage hcVSMCs (passage 2-4) were obtained from human cerebral artery explants. Briefly, 2 mm slices of human pial artery (IRB# CHRMS 01-195; informed consent) were applied to scored 60 mm culture dishes, cultured in SMGM2 media (Cambrex Bio Science, Hopkinton, MA), and passaged with trypsin/EDTA. For hypoxia exposure, cells were incubated at 2% O2 by N2 injection into a humidified CO2 incubator (Forma, Marietta, OH). NOC-18, Cu/Zn superoxide dismutase (SOD), catalase, xanthine, and xanthine oxidase were obtained from Calbiochem (San Diego, CA). S-nitroso-L-glutathione (GSNO) was obtained from Alexis
Growth protocol hcVSMCs and rat VSMCs (passages 2-4) were grown to approximately 60% confluence and serum starved in DMEM containing 0.1% FBS 24-48 hr prior to treatment
Extracted molecule total RNA
Extraction protocol Total RNA was extracted from treated hc VSMCs using TriZol reagent and chloroform. RNA was precipitated using isoproponol and glycoblue, washed with 75% ethanol, dissolved in RNAse free water and quantified using the NanoDrop® spectrophotometer.
Label biotin-labeled
Label protocol Double-stranded cDNA was then synthesized followed by an in vitro transcription reaction and fragmentation reaction to produce biotin-labeled cRNA fragments that were hybridized to the probe array at 45°C for 16 hr
 
Hybridization protocol biotin-labeled cRNA fragments that were hybridized to the probe array at 45°C for 16 hr
Scan protocol The probe arrays were scanned (Hewlett-Packard GeneArray Scanner, Agilent Technologies, Inc.) to quantify the fluorescence intensity associated with each oligonucleotide probe.
Description each of three experiments cell cultures were split three ways; one of the resulting samples was left untreated (C), another was treated with thapsigargin (TG), and the third was treated with elevated K+ (K)
