Human F1Fo-ATPsynthase deficiency
 Suldovská, Sabina ; Tesařová, Markéta (advisor) ; Černá, Leona (referee)
F1FO-ATPsynthase is a key enzyme in energy metabolism of the cell. Its deficit is caused usually by mutations in two structural genes MT-ATP6 and MT-ATP8 encoded by the mitochondrial DNA or in nuclear genes ATPAF2 and TMEM70 encoding the biogenesis factors and structural gene ATP5E. Deficiency of the F1FO-ATPsynthase leads to progressive and serious phenotype affecting organs with high energy demands. The first symptoms usually occurs in neonatal age and prognosis of the disease is fatal. Mutations in these genes result in both qualitative and quantitative defects of the F1FO-ATPsynthase. The study of molecular bases of mitochondrial disorders including F1FO-ATPsynthase deficiency uses large number of biochemical and molecular-genetic methods to determine a proper diagnosis which is essential for the symptomatic therapy and genetic counselling in affected families. The aim of the diploma thesis was to characterise the F1FO-ATPsynthase deficiency in isolated mitochondria from the lines of cultured cells by the determination oligomycin- sensitive ATP-hydrolytic activity of the F1FO-ATPsynthase, enzymatic activities of the respiratory chain complexes and to analyse changes in the steady-state levels of the representative subunits and whole complex of the F1FO-ATPsynthase in comparison with controls. 3...
