Research Abstract

The present study examined a role of mucosa-associated lymphoid tissue 1 (MALT1), whose expression is inactivated in oral carcinomas with worse prognosis, in oral carcinoma cells and its involvement in phenotypic alteration of the cells by the microarray and proteomic analyses. MALT1 down-regulated expression of genes in the TGF-ss and EGF pathways, alternated keratin species involved in aggressive feature of carcinoma cells, and suppressed proliferation and migration of the cells. Furthermore, E-cadherin-mediated carcinoma cell-cell adhesion machinery, which was also strongly down-regulated by MALT1, was rapidly obstructed with progression of oral carcinomas.
