Research Abstract |
Most cancers arise from a single cell of origin in an epithelial sheet. Therefore, a newly emerged oncogenic cell in the epithelium has to confront anti-tumor selective pressures in the host tissue. However, the mechanisms by which surrounding normal tissue exerts anti-tumor effects against oncogenically transformed cells are poorly understood. Using the Drosophila genetics, we found that normal epithelial cells activate JNK-dependent engulfment pathway in response to the emergence of oncogenic polarity-deficient cells, thereby eliminating oncogenic neighbors through cell competition.
