| Outline of Final Research Achievements |
Head and neck squamous cell carcinoma(HNSCC) results in cervical lymph node metastasis and distant metastasis and is often discovered as progressive cancer, and the prognosis is very poor. It is difficult to aim at the radical cure for a case resulting in distant metastasis in particular, but the metastatic mechanism is unknown. Recently, about twenty base micro RNAs which do not encode protein has been studied all over the world.
Using a specimen operated at a hospital attached to the Chiba University School of Medicine, we made the downregulated microRNAs profile in HNSCC. Moreover, we identified tumor suppressive microRNAs in the profile, and elucidated the functional roles of cancer metastasis network controlled by the tumor suppressive microRNAs.
