|
| Source name |
4 months old SHHF obese rat, left ventricular
|
| Organism |
Rattus norvegicus |
| Characteristics |
Strain: SHHF, Gender: Male, Age: 4 months, Tissue: left ventricular, Other: hypertension, metabolic syndrom, dilated cardiomyopathy starting from 10 months old
|
| Biomaterial provider |
Charles River laboratory
|
| Treatment protocol |
None
|
| Growth protocol |
Animals were lodged in the Zootechnic service of the Louis Bugnard Institute. A veterinary oversees animal health and management. Temperature : 22 +/- 1 degrees. Cycles nights/days : 12 hours. Food : Teklad Global 16% Protein Rodent Diet (Harlan)
|
| Extracted molecule |
total RNA |
| Extraction protocol |
General anesthesia by Isoflurane 4%. Heart extraction. Isolation of total RNA from left ventricular by : TRIzol (Invitrogen), homogeneisor Ika Ultra-Thurax T 25 (Janke and Kunkel), DNAfree (Ambion). Quality and quantity were determined by capillary electrophoresis (Agilent).
|
| Label |
33P
|
| Label protocol |
Reverse Transcription of 3 µg total RNA from each left ventricular with Superscript enzyme (Invitrogen). Purification of cDNA labelled with 33P with NucleoSpin Extract (Macherey-Nagel)
|
| |
|
| Hybridization protocol |
Using one nylon membrane per animal for the hybridization (kit Array-Advantage GF, Ambion)
|
| Scan protocol |
Exposition of each membrane during 24 hours (Storage Phosphor Screen, Molecular Dynamics). Revelation with Scan Typhoon 9400 (resolution at 50 µm per pixel). Analysis of images by Image Quant 5.1
|
| Description |
no functional leptin receptor
|
| Data processing |
background subtraction, log transformation, normalization by total mean, exponential (back from log), scaling by a factor 10000.
