Transcription profiling of rat heart after treatment with PETN or NTG


ABSTRACT: Male Wistar rats (6 weeks, 250g), (Charles River, Sulzfeld, Germany) were equipped with micro osmotic pumps model 2001 from Alzet (Cupertino, CA) containing 400mM PETN dissolved in DMSO or the solvent and infusion was maintained for four days at 1?l/h (10.5?g/kg/min). For direct comparison, rats were also infused with 450mM NTG (6.6?g/kg/min in ethanol or the solvent as a control).
After 4d rats were sacrificed by exsanguinations under Isofluran anesthesia (5% inhalant in room air), the heart was rapidly excised, placed in ice-cold Krebs-HEPES-solution (composition in g/l: 5.78 NaCl, 0.35 KCl, 0.37 CaCl2, 0.30 MgSO4, 2.1 NaHCO3, 0.14 K2HPO4, 5.21 HEPES and 2.0 D-glucose) and dissected.
Total RNA was isolated from the hearts. Direct labeled cDNA was synthezised and hybridized to Rat OpArray Microarray (total genom expression profiling).
