Outline of Final Research Achievements

This study focused on hypopharyngeal carcinoma, which has a poor prognosis, and aimed to determine the role of non-coding RNAs in cancer cells. Our results showed that suppression of Molecule X decreased the proliferative capacity of cancer cells and altered their migratory ability and cell cycle. In addition, the binding of Molecule X and Protein Y was confirmed, and both were highly expressed in cancerous areas. This study raises the possibility that Molecule X is involved in the growth of hypopharyngeal cancer and is specifically regulated by its interaction with Protein Y. This is an important finding for the development of new targeted therapies.

Academic Significance and Societal Importance of the Research Achievements

下咽頭がんは主に扁平上皮癌で占められるが、有効な治療標的がないため進行がんの治療には難渋する。私たちは新しい治療標的をみつけるために、機能性RNAに着目してスクリーニングしたところ、分子Xが下咽頭がんの増殖に大きく関与することを見出した。さらに分子XはタンパクYと複合体を形成して機能することが示唆された。このことから、同複合体を治療標的として腫瘍縮小を狙えることが示唆され、さらなる基礎実験・データの蓄積が必要である。
