Table 2. Individual data of expression levels of MMP-9 mRNA in AVMs and normal tissues.
| AVM | MMP-9 mRNA | Normal Tissue | MMP-9 mRNA |
|---|---|---|---|
| 1 | 0.03 | 1 | 0.09 |
| 2 | 0.53 | 2 | 0.72 |
| 3 | 2.85 | 3 | 0.39 |
| 4 | 5.78 | 4 | 1.00 |
| 5 | 4.27 | 5 | 0.47 |
| 6 | 0.65 | 6 | 0.85 |
| 7 | 1.01 | 7 | 0.84 |
| 8 | 0.22 | 8 | 0.24 |
| 9 | 1.91 | 9 | 10.22* |
| 10 | 4.23 | 10 | 13.03* |
| 11 | 1.60 |
*Note: Normal tissues 9 and 10 have abnormally high level of MMP-9 mRNA, histology examination shows lymphatic malformation invasion (9) and ear dermoid cyst (10). These two data were deleted when statistical analysis was conducted.
