Table 4. Expression levels, carbonyl levels and enzyme activity of GAPDH in controls (CTR), dysplastic (DYS) and carcinoma tissues (SCC) are reported.
| CTR | DYS | SCC | |
| GAPDH Expression levels(fold vs. CTR) | 1±0.1 | 1.6±0.3 | 2.4±0.2 |
| GAPDH Carbonylation levels(fold vs. CTR) | 1±0.3 | 9.0±0.4 | 1.2±0.3 |
| GAPDH Enzymatic activity(uA/mg) | 45±5.4(100±12%) | 26.8±6.3(59.5±14%) | 52.8±4.9(117.3±11%) |
Levels are expressed as fold increase/decrease vs CTR. Enzyme activity is calculated as A340/mg protein and also as % vs CTR. Data are expressed as mean ± SEM.
