The role of mitochondrial genome in cardioprotection induced by the adaptation to chronic hypoxia
Nedvědová, Iveta
Cardiovascular intervention studies are a very important issue given that the ischaemic heart disease is one of the main mortality and morbidity causes in the Western world. Cardioprotection is mediated through a variety of signalling pathways in the cell that may directly or indirectly affect energy metabolism and mitochondria. Ischaemia-reperfusion injury of the heart significantly affect mitochondrial function revealing a potential therapeutic target. The role of mitochondria in the myocardium is not only in the field of energy homeostasis, but also in mediating the cellular response to reduced oxygen supply and in apoptosis regulation. This thesis aims to elucidate the response of the hypertrophied heart of the spontaneously hypertensive rat (SHR) and the derived conplastic strain with mitochondrial genome of normotensive Brown Norway (SHR-mtBN ) to the cardioprotective regime of adaptation to chronic normobaric hypoxia (CNH, Fi 0.1). The adaptive changes were studied at the cellular, protein and gene levels using Real-time RT-PCR, Biomark Chip Analysis, Western Blot, spectrophotometric measurements of enzyme activity and quantitative immunofluorescence analyses. The present thesis was based on a different cardioprotective phenotype between SHR and SHR-mtBN strains, i.e. a significantly smaller...
