| Outline of Final Research Achievements |
Main purpose of this study is to demonstrate the efficacy of mRNA-binding protein Sam68 as new biomarker and therapeutic target in oral squamous cell carcinoma (OSCC). Immunohistochemical staining study of Sam68 in OSCC tissues revealed that OSCC with metastasis to cervical lymph nodes had high expression of cytoplasmic Sam68. The differences of stress-induced cytoplasmic granules (Stress granules) were observed between cancer cells and normal cells.

| Academic Significance and Societal Importance of the Research Achievements |
本研究では、Sam68の細胞質内発現の増加が口腔扁平上皮癌の転移能に寄与していることが示唆された。また、正常細胞とがん細胞ではStress granulesの挙動が異なり、ストレス下でのmRNA制御機構に違いがあることが示唆された。これらの結果は、口腔扁平上皮癌のSam68細胞質内高発現やがん細胞でのStress granulesの特異的挙動が、新規バイオマーカーおよび治療標的として有用である可能性を示している。
