Sample GSM1193122 Query DataSets for GSM1193122
Status Public on May 09, 2014
Title PBMC_Ctrl_subj6
Sample type RNA
 
Source name Peripheral blood mononuclear cells, 13hr incubation with 0.05% DMSO (control), subject 6
Organism Homo sapiens
Characteristics gender: male
subject: 6
age: 65 yr
age group: old
tissue: cultured peripheral blood mononuclear cells
treatment: 0.05% DMSO
Treatment protocol Peripheral blood mononuclear cells were incubated in RPMI1640 medium with 2 mmol/L L-glutamine, 10% fetal bovine serum and antibiotics (penicillin and streptomycin) in the presence of 5% CO2 at 37°C at 1.0 × 10^6 cells per ml with either WY14,643 (50 μM) or vehicle (DMSO, 0.05%). After 13 hrs of exposure the cell suspensions were transferred to 15ml tubes and centrifuged for 5 minutes at 1,600rpm at 4°C. The two cell pellets per donor were re-suspended in ice-cold PBS, and each transferred to separate eppendorf tubes for RNA and DNA isolation and again centrifuged for 5 minutes at 5,000rpm at 4°C. After removing the supernatant, pellets for DNA isolation were snap frozen on dry-ice and stored at -80°C. The pellets for RNA isolation were resuspended in 700 μL of Buffer RPE with added B-mercaptoethanol according to manufacturer’s instructions (Qiagen) and passed five times through a 23G needle before freezing at -80°C.
Growth protocol Peripheral blood mononuclear cells from ten healthy Caucasian male blood donors, aged 30, 31, 34, 35, 43, 52, 62, 64, 65 and 66 years, were isolated directly after arrival of the buffy coat (max. 8 hours after donation) by Ficol-paque Plus density gradient centrifugation (Amersham Biosciences, Roosendaal, the Netherlands). All donors gave full written informed consent.
Extracted molecule total RNA
Extraction protocol Total RNA was isolated using RNeasy micro kit from Qiagen. RNA integrity was checked on chip analysis (Agilent 2100 bioanalyzer, Agilent Technologies, Amsterdam, the Netherlands) according to the manufacturer's instructions. RNA was judged as suitable for array hybridization only if samples exhibited intact bands corresponding to the 18S and 28S ribosomal RNA subunits, and displayed no chromosomal peaks or RNA degradation products (RNA Integrity Number > 8.0).
Label biotin
Label protocol One hundred nanogram of RNA was used for whole transcript cDNA synthesis with the Ambion WT expression kit [catalog number 4411974] (Applied Biosystems/Life Technologies, Nieuwekerk a/d IJssel, The Netherlands).
 
Hybridization protocol Hybridization and washing of the Affymetrix GeneChip Human Gene 1.1 ST peg arrays were performed on a GeneTitan Instrument (Affymetrix, Santa Clara, CA) according to the manufacturer's recommendations.
Scan protocol Arrays were scanned on an Affymetrix GeneTitan instrument (Affymetrix, Santa Clara, CA).
Data processing Expression estimates were calculated applying the RMA algorithm in the Bioconductor library 'Oligo' (v1.24.0).
