Figure 3 SOD Expression and Activity in Normal and Stenotic Aortic Valves
(A) Expression of the 3 superoxide dismutase (SOD) isoforms in normal and noncalcified and calcified regions of stenotic aortic valves (n = 16 normal valves, n = 15 stenotic valves). (B) Regional total SOD activity in stenotic aortic valves (n = 10 normal valves, n = 11 stenotic valves; *p < 0.05 vs. normal valves; #p < 0.05 vs. noncalcified stenotic tissue). mRNA = messenger ribonucleic acid; other abbreviations as in Figure 1.
