| Research Abstract |
A newly emerged oncogenic cell in the epithelium has to confront anti-tumor selective pressures in the host tissue. However, the underlying mechanism is poorly understood. Using Drosophila model system, we found that normal epithelial cells activate JNK signaling through "cell competition" in response to the emergence of oncogenic polarity-deficient cells, which activates phagocytic pathway, thereby eliminating oncogenic neighbors by engulfment.
