ABSTRACT
Objective To investigate the expression and significance of microtubule-associated protein 1 light chain 3 (LC3), an autophagy marker protein, in ameloblastomas. Methods Immunohistochemical methods were employed to evaluate the expression of LC3 in104 cases of ameloblastomas and 20 cases of normal oral mucosal tissues. The results were analyzed by a semiquantitative analysis method. Results The reactivity of LC3 in the epithelial cells of ameloblastomas was positive, and the positivity rate was significantly higher than that in normal oral mucosal tissues (P < 0.05). There were no significant differences between the LC3 expression levels with respect to age, gender, or recurrence (P < 0.05). The positivity rate in mandible ameloblastomas was significantly higher than that in maxilla and gingiva ameloblastomas (P < 0.05). The reactivity for LC3 was significantly higher in solid ameloblastomas than that in the other three tissue types (P < 0.05). Conclusion Autophagic activity in ameloblastomas was higher than that in normal oral mucosal tissues. This suggests that autophagy plays an important role during tumorigenesis, and contributes to the local invasion of ameloblastomas.
