Transcription profiling of rat heart at several time points after either a myocardial infraction or sham operation


ABSTRACT: Myocardial Infarction Model: Sixty nine animals (252 ± 2 g) were randomized to either myocardial infraction (MI) or sham operation. MI were produced by partial ligation of the left coronary artery as described in detail by Loennechen et al. (Loennechen JP, Stoylen A, Beisvag V, Wisloff U, Ellingsen O: Regional expression of endothelin-1, ANP, IGF-1, and LV wall stress in the infarcted rat heart. Am J Physiol Heart Circ Physiol 2001, 280: H2902-H2910.). Animals with large infarctions (45 ± 2% of LV) were euthanized on one of the following days: day 1 (n = 6), 3(n = 5), 7 (n = 6), 14 (n = 6), 42 (n =6) and 91 (n = 4); and sham-operated animals were euthanized on one of the following days: 1 (n = 6), 3(n = 6), 7 (n = 6), 14 (n = 6), 42 (n =6) and 91 (n = 6). After sacrifice, heart tissue was removed, weighted and scored for size of the healed infarction. Infarct size was measured and the left ventricular myocardium stored on -80°C for preparation of RNA.
