CAT | CuZnSOD | GPX | MnSOD | ALR2 | |
---|---|---|---|---|---|
Z − 2/X (n = 15) | 0.4 ± 0.04* | 0.3 ± 0.02†‡ | 0.4 ± 0.03§ | 0.8 ± 0.02 | 4.7 ± 0.8 |
Z + 2/Y (n = 3) | 0.6 ± 0.08 | 1.7 ± 0.47 | 0.6 ± 0.05 | 0.8 ± 0 | 2.0 ± 0.5 |

Data are mean fold increases ± SE of the PBMCs exposed to hyperglycemia versus those cultured under normal conditions. X, any allele other than Z + 2; Y, any allele other than Z − 2.
* versus CAT X/Y, P = 0.02.
† versus CuZnSOD Z + 2/Y, P < 0.001.
‡ versus CuZnSOD Z − 2/Z + 2, P = 0.009.
§ versus GPX Z + 2/Y, P = 0.02.
