Title |
Dex and COS conditions rep 2 |
Sample type |
RNA |
|
|
Channel 1 |
Source name |
C2C12
|
Organism |
Mus musculus |
Characteristics |
cell type: Myotubes treatment: DEX+COS culture conditions day 5-8 post differentiation: 4% O2, low-frequency (1Hz/0.1Hz for 18h/6h respectively) biphasic 5ms square-wave electrical stimulation, and daily TNF-α (20 pg/ml; R&D systems) and IL-6 (100 pg/ml; R&D systems) + daily Dexamethasone (1µM)
|
Treatment protocol |
All treatments started day 5 post differentiation including transfer to new culture conditions (COS) and/or treatment with additional soluble agents. All media and treatments were changed every 24hrs prior to harvesting cells (D5-D7).
|
Growth protocol |
C2C12 myoblasts (ATCC) less than 10 passages grown in high-glucose DMEM (Gibco) with 10% FBS (invitrogen) seeded on 0.15% gelatin-coated 6-well plates at at 2.2 x 10^6 cells per well, grown to 80% confluence and differentiated in medium containing 10% horse serum. All initial cultures were performed in standard tissue culture conditions (21% O2, 5% CO2, humidified incubator at 37C)
|
Extracted molecule |
total RNA |
Extraction protocol |
RNA was extracted using the miRNeasy mini protocol (Qiagen) as per the manufacturer's instructions
|
Label |
Hy3
|
Label protocol |
2µg total RNA from each experimental sample was covalently 3’-labeled with a single Hy3 (test) or Hy5 (reference) fluorophore per molecule using the Hi-Power Labeling kit (Exiqon, Woburn MA)

|
|
Hybridization protocol |
Performed on fully-automated enclosed hybridisation station (Tecan HS400Pro). Samples were injected manually then co-hybridised (56 degrees C x 16 hrs) then washed and dried automatically prior to scanning
|
Scan protocol |
Scanned on an Agilent G2505B scanner.
|
Description |
Biological replicate 2 of 2: Dex treatment under COS conditions vs COS conditions
|
Data processing |
Two-colour images were analysed using Spot software (CSIRO, 2007) and mean signal intensity for each spot was determined after background correction and Loess print-tip (within-array) normalisation of the log2 ratio (FlexArray, Genome Quebec, McGill University). Normalized log2 ratio (Hy3/Hy5)
