| Outline of Final Research Achievements |
To evaluate the role of cancer stem cells in lung cancer, we developed patient-derived xenografts (PDXs) on NOG mice. We sorted the cells from lung squamous cell carcionoma PDXs by known cell surface markers and xenograft into NOG mice. We found that high expression of a molecule XX possess high tumorigenicity. By XX knock down using siRNA, the proliferation capacity was completely inhibited. Apoptotic cells were increased and migration capability was attenuated by XX knock down. These results suggested that XX may be a good therapeutic target for lung squamous cell carcionoma.
