Female controls also showed lowered ETF‐linked LEAK (p < 0.0001), cytochrome c response (p = 0.009), complex I (p = 0.001) and complex II (p = 0.042) activity, and OPCE ratio (p = 0.020) in ischemia‐reperfused tissue compared to control males (Table 1). The gene discussed is CYCS; the disease is ischemia.
