Hypobaric hypoxia induces right ventricular hypertrophy. The relative contribution of pulmonary hypertension, decreased arterial oxygen, and neuroendocrine stimulation to the transcriptional profile of hypoxia-induced right ventricular hypertrophy is unknown. Whereas both ventricles are exposed to hypoxia and neuroendocrine stimulation, only the right(More)
BACKGROUND The peroxisome proliferators-activated receptor-alpha (PPARalpha), a transcription factor that modulates fatty acid metabolism, regulates substrate preference in the heart. Although in acute ischemia there is a switch in substrate preference from fatty acids to glucose, metabolic gene expression in repetitive ischemia is not well described. In a(More)
