| Title |
COPD [294945_miRNA] |
| Sample type |
RNA |
| |
|
| Source name |
Lung tissue from smoker with COPD
|
| Organism |
Homo sapiens |
| Characteristics |
diagnosis: COPD
fvc-group: 1
gold stage: 4
age: 52
gender (1=male, 2=female): 2
pkyrs: 1
|
| Extracted molecule |
total RNA |
| Extraction protocol |
Total RNA was isolated from frozen tissue samples using a freeze fracture protocol, followed by Trizol extraction and precipitation at -20ºC overnight to increase the yield of small RNAs. RNA integrity was determined by capillary electrophoresis on an Agilent 2100 Bioanalyzer. Only RNA with an integrity number $7 was used in the profiling studies.
|
| Label |
Cy3
|
| Label protocol |
miRNAs were labeled according to the manufacturer's instruction (Exiqon, Woburn, Massachusetts, USA)
|
| |
|
| Hybridization protocol |
The labelled miRNA probes were hybridized to the miRCURY LNA arrays v11.0 for 16h at 56ºC
|
| Scan protocol |
Hybridized slides were washed and scanned with ScanArray Express (Perkin Elmer)
|
| Description |
COPD
|
| Data processing |
miRNA expression data was consolidated by taking median value across replicated probes. Then, it was normalized by quantile method, and transformed in log2-scale
