FAT1 [Homo sapiens FAT tumor suppressor homolog 1 (Drosophila)] is an intrinsic membrane protein classified as a member of the Cadherin superfamily The FAT1 gene is a tumor suppressor in humans as well as being the pivotal gene for cell morphogenesis and migration. Deletion of this gene could play a role in the characteristics of oral squamous cell carcinomas (OSCCs), involving cell adhesion, migration and/ or invasion. This study investigated the mechanisms by which FATl is involved in the biological behavior of OSCCs. First, a rat monoclonal antibody was developed against a FAT1 intracellular domain epitope, and used for an immunohistochemical study of FATl in clinically obtained OSCC samples. FATl was localized at lamellipodial edges or cell-cell boundaries in normal cells and well differentiated OSCCs, but showed a diffuse cytoplasmic and nuclear distribution in moderately-poorly differentiated OSCCs. FAT1-siRNA was transfected into OSCCs resulting in a drastic inhibition of cell migration and invasion based on the suppression of FAT1 expression and disorganized localization of β-catenin which is associated with cell polarity and migration. These results suggested that FAT1 may be involved in the migration and invasion mechanisms of OSCCs and, therefore, it could be an important target for the development of new therapeutic strategies.

Aims: The aim was to determine the prevalence of erosion in 13- to 14-year-old children on the Isle of Man and to investigate the strength of association with dietary risk factors. Methods: Exposed dentine was assessed on smooth surfaces of incisors/canines and occlusal surfaces of first molars. A questionnaire assessed the consumption frequency of foodstuffs. Results: Of 629 children examined, 124 (20%) had dentine exposed labially, palatally or occlusally. More males had dentine exposed on these surfaces (OR = 1.7, 95% CI = 1.2-2.6). Palatal dentine exposure was present in 3% of the children and occlusal dentine exposure in 18%. In bivariate analyses, drinking fizzy drinks more than once a day was associated with erosion (OR = 1.6, 95% CI = 1.1-2.3). The mean DMFT scores were not statistically different for the children with smooth surface/occlusally exposed dentine (1.37) compared to those without (1.58). Multiple regression analysis showed age, gender and toothbrushing to be significant predictors of erosion. Conclusion: This study has found a higher proportion of 13- to 14-year-old children with exposed dentine in molars than previous studies. The results corroborate previous reports that males have more erosion than females. © 2010 S. Karger AG, Basel.
