Mitochondrial energy conversion disturbance with decrease in ATP production as a source of systemic arterial hypertension  Yuvenalii V. Postnov, Sergei N. Orlov, Yegor Y. Budnikov, Alexander D. Doroschuk, Anton Y. Postnov  Pathophysiology  Volume 14, Issue 3, Pages (December 2007) DOI: /j.pathophys Copyright © 2007 Elsevier Ireland Ltd Terms and Conditions

2 Fig. 1 Major systems involved in oxidative phosphorylation and Ca2+ transport in mitochondria. Abbreviations: IMM, inner mitochondrial membrane; PM, plasma membrane; I-IV, complexes providing electron (e−) transport from NADH to O2; 1, mitochondrial ATP synthase (F1Fo-ATPase); 2, adenine nucleotide translocase; 3, phosphate carrier; 4, Ca2+ uniporter; 5 and 6, Ca2+/Na+ and Ca2+/H+ antiporters, respectively; 7, mitochondrial permeability transition (MPT) pore; 8 and 9, Ca2+-ATPase and Na+, K+-ATPAse, respectively. Factors involved in activation (+) and inhibition (−) of MPT are shown by broken arrows. For more details, see the text. Note that the scheme does not reflect the relative locations of membrane proteins. Pathophysiology  , DOI: ( /j.pathophys ) Copyright © 2007 Elsevier Ireland Ltd Terms and Conditions

3 Fig. 2 Rate of ATP synthesis in isolated mitochondria from the liver and brain of SHR and WKY rats measured in Ca2+-free medium. Mean values obtained in mitochondria from WKY were taken as 100%. *p<0.01. For more details, see [22,23].

5 Fig. 4 Dependence of the ATP synthesis rate by mitochondria isolated from SHR and WKY rat livers on free Ca2+ concentration. For more details, see [26–28]. Pathophysiology  , DOI: ( /j.pathophys ) Copyright © 2007 Elsevier Ireland Ltd Terms and Conditions

6 Fig. 5 Kinetics of Ca2+-induced Ca2+ release in mitochondria isolated from SHR and WKY rat livers. Abbreviations: V1, rate of calcium uptake by mitochondria; Cmin-SHR, Cmin-WKY, minimal values of Ca2+ concentrations in the incubation medium; V2-SHR, V2-WKY, rates of Ca2+ release from mitochondria; tSHR, tWKY, times of cycle duration; M, addition of mitochondria into incubation medium containing free [Ca2+] at the initial concentration of 55μM.
