Chronic hypoxia reduced glycosylation level of the beta-1 regulatory subunit of the cardiac mitochondrial large-conductance calcium-activated potassium channels (BK). Ventricular myocytes isolated from chronically hypoxic rats retained the improved resistance against injury caused by simulated ischemia/reperfusion. The blunting effect of paxilline (BK inhibitor) and the absence of additive protection by NS-1619 (BK opener) suggest that chronic hypoxia leads to the activation of these channels, which contribute to the protective mechanism
