|
Source name |
HUVEC
|
Organism |
Homo sapiens |
Characteristics |
tissue: HUVEC sirna: control siRNA sirna treatment time point: 12hr
|
Treatment protocol |
siRNA treatment was performed through lipid-based transfection method with either PPARa siRNA (Cat. No. M-00343400) or control siRNA (Cat. No. D-001206-13), using SmartPool reagents (Dharmacon, Lafayette CO, USA) according to the manufacturers' instructions. HUVECs from 10 individuals were pooled, plated at 2.2×105 cells in six-well plates and allowed to recover for 24 hours at 37ºC/5%CO2, at which time they were approximately 80% confluent. For transfection, 5ul/well of 20uM RNAi (PPARa or control), 42ul/ well of siFECTAMINE (ICVEC, UK no longer available) and 500ul/well of serum-free medium were incubated at room temperature for 5 minutes. The relevant transfection mix was then added to each well containing 500 μl of fully supplemented media and incubated at 37ºC/5%CO2 for 3 hours after which the transfection medium was replaced with 3ml of fresh fully supplemented medium. 24 hours post transfection relevant wells were treated with 25umol fenofibrate (Sigma-Aldrich, UK) dissolved in DMSO (Sigma-Aldrich, UK). Cells were incubated at 37ºC/5%CO2 for the time points in transcriptional profiling.

Growth protocol |
HUVECs were isolated from umbilical cords by collagenase digestion and cultured at 37ºC/5%CO2 in basal culture medium supplemented with a proprietary mixture of heparin, hydrocortisone, epidermal growth factor, FGF and 2% foetal calf serum (FCS; EGM-2, Cambrex, Workingham, UK).

Extracted molecule |
total RNA |
Extraction protocol |
Total RNA was prepared from fenofibrate-treated or -untreated HUVECs using Trizol reagent (Invitrogen)
|
Label |
biotin
|
Label protocol |
Biotin-labelled complex cRNAs were prepared to according to the manufacturer's protocols (Applied Microarrays, formally supplied by GE Healthcare)
|
|
|
Hybridization protocol |
Biotin-labelled complex cRNAs were hybridized to CodeLink UniSet I Human 20K according to the manufacturer's protocols (Applied Microarrays, formally supplied by GE Healthcare).
|
Scan protocol |
The arrays were scanned with Agilnet DNA Microarray Scanner model G2565BA.
|
Description |
none
|
Data processing |
The scanned images were quantified with CodeLink Expression Array Software (Applied Microarrays, formally supplied by GE Healthcare), where the intensity of each spot was divided by the spot’s signal median.
