Analysis of mitochondrial Ca²⁺ transients of sorcin-overexpressing cells. A: typical recording of Ca²⁺ transients from a cell infected with Adv-control and a cell infected with Adv-sorcin. B: cumulative diastolic and systolic mitochondrial Ca²⁺ concentrations ([Ca²⁺]_m) in control and sorcin-overexpressing cells. C: magnitude of the Ca²⁺ transient (difference between diastolic and systolic Ca²⁺). D: effect of sorcin on mitochondrial Ca²⁺ uptake and release. Values are means ± SE, n = 20 cells per group. *P < 0.05 vs. control.
