Systemic exposure to 13% oxygen for 24 h increases SUR2A, ATP and CK in the myocardium. Original Western blots for SUR2A under labeled conditions (A) and corresponding graph (B) as well as bar graphs depicting ATP (C) and CK levels (D) in the myocardial tissue under the same conditions. Each bar is a mean ± SEM (n = 3–5). *P < 0.05. AU = arbitrary units. Western blots and methods used to measure ATP and CK are described in details in refs. [2] and [3].
