Western blot analysis for cyclooxygenase (COX) expression in coronary arteries from Dex-exposed and control (CTL) sheep. Representative immunoblots probed with antibodies against COX1 (A, molecular mass 72 kDa) and COX2 (B, molecular mass 72 kDa) identify bands between the 75- and 50-kDa molecular mass markers (white bars). There were no significant differences in COX expression between control (open bars, N = 6) and Dex-exposed sheep (shaded bars, N = 6) (B).
