ZEB1 and α-SMA expression in human oral submucous fibrosis
| Case Number | Weak/moderate | Strong | P value | |
|---|---|---|---|---|
| ZEB1 | ||||
| Normal | 10 | 7 | 3 | |
| OSF | 30 | 6 | 24 | 0.006 |
| α-SMA | ||||
| Normal | 10 | 7 | 3 | |
| OSF | 30 | 8 | 22 | 0.024 |
ZEB1 or α-SMA expression in human normal buccal mucosa or OSF was determined by immunohistochemistry as described in Materials and methods section. Specimens with 10–50% immunoreactive cells were considered as weak/moderate expression and there were more than 50% immunoreactive cells, which were defined as strong expression. P value was calculated by Fisher's exact test.
