Outline of Final Research Achievements

The goal of this study was to detect alternative splicing of MUC1 mucin in oral squamous cell carcinoma and to evaluate its relationship with clinicopathological factors. First, we investigate the expression level of membranous mucin in the resected tumor samples by immunohistochemistry and found that aberrant expression MUC1 was an independent prognostic factor indicating poor prognosis in patients with OSCC. Next, we have started to evaluate the expression level of each splicing variant of MUC1, using the specimen from surgically resected oral squamous cell carcinoma. The expression level and proportion of MUC1 splicing variants showed a huge variety in each specimen. The specific splicing variants may play a critical role for progression of OSCC and these might be the target of OSCC therapy in the future.
