| Outline of Final Research Achievements |
We previously reported that CD271 (p75 neurotrophin receptor) is a marker for tumor formation and correlated with a poor prognosis in human hypopharyngeal cancer. To elucidate the role of CD271 in HPC, we established HPC cell lines and CD271-knockdown cells using siRNA. We revealed that CD271-knockdown strongly suppressed the tumorigenesis and cell growth.In addition, CD271 depletion diminished the in vitro migration capability of the HPC cells. Collectively, CD271 initiates tumor formation by increasing the cell proliferation capacity and by accelerating the migration signaling pathway in HPC.
