| Research Abstract |
The purpose of the present study is to find markers, which might be molecules of targeted cancer therapy for the patients with oral squamous cell carcinoma(OSCC),by means of investigating the expression level of splicing isoforms of cancer-related genes in samples from patients with OSCC. The correlation between the expression level of several genes and clinicopathological factors was also evaluated. We harvested samples of the biopsy and operation in 107 patients with OSCC,and investigated the expression level of proteins of MUC1, MUC4, VEGF, and SULF2. Also mRNA expression of each cancer-related genes in the oral rinse obtained from 55 patients with OSCC was semi-quantitated by RT-PCR.The results obtained are as follows :
I. The expression level of SULF2, MUC1 and MUC4 was significantly correlated with higher T classification, metastasis to regional lymph node, advanced tumor stage and poor prognosis. II. The expression levels of cancer-related genes were varied in each patient. III. The specific primer sets for MUC1, VEGF and VEGFR splicing variants were conducted, and those sensitivity and specificity were confirmed by using cultured cell. These results suggest that the expression level of SULF2, MUC1 and MUC4 gene might be the new useful prognostic factors of OSCC patients.
