| Title |
Monocyte_obese_rep1 |
| Sample type |
RNA |
| |
|
| Channel 1 |
| Source name |
Human, CD14+ monocytes, obese
|
| Organism |
Homo sapiens |
| Characteristics |
gender: female
cell type: CD14+ monocytes
disease state: obese
gender: female
cell type: CD14+ monocytes
disease state: lean-obese
|
| Growth protocol |
Blood samples were collected and after removal of the plasma fraction, peripheral blood mononuclear cells (PBMCs) were isolated using gradient separation on Histopaque-1077. CD14+ monocytes were isolated from the PBMC fraction using CD14 immunomagnetic beads (Miltenyi).
|
| Extracted molecule |
total RNA |
| Extraction protocol |
Total RNA was extracted with Trizol reagent, followed by clean-up and DNase I treatment with Qiagen miRNeasy mini kit in accordance with the prescribed protocol provided with the kit. Quality control was performed with Agilent Bioanalyzer.
|
| Label |
Hy3
|
| Label protocol |
600 ng total RNA from sample and reference pool was labelled with Hy3 and Hy5 fluorescent label, respectively, using the miRCURY LNA Array power labelling kit (Exiqon).

|
| Channel 2 |
| Source name |
Human, CD14+ monocytes, lean-obese reference pool
|
| Organism |
Homo sapiens |
| Characteristics |
gender: female

|
| |
|
| |
| Hybridization protocol |
The hybridization was performed according to the miRCURY LNA array manual using a Tecan HS4800 hybridization station.
|
| Scan protocol |
The microarray slides were scanned using the Agilent G2565BA Microarray Scanner System and the image analysis was carried out using the ImaGene 8.0 software (BioDiscovery).
|
| Data processing |
The quantified signals were background corrected (Normexp with offset value 10) and normalized using the global LOWESS (LOcally WEighted Scatterplot Smoothing) regression algorithm.
