Normal epithelial tissues often put anti-tumorigenic pressure on newly emerged oncogenic cells through cell-cell communications. In Drosophila epithelium, clones of oncogenic cells mutant for evolutionarily conserved apico-basal polarity genes such as scribble (scrib) and discs large (dlg) are actively eliminated when surrounded by normal cells. It has been reported that c-Jun N-terminal kinase (JNK) signaling in polarity-deficient cells is crucial for their cell death. However, the mechanism by which normal epithelial tissues exert anti-tumorigenic effects on polarity-deficient cells had been elusive. Here, I describe our genetic studies in Drosophila epithelium especially focused on the role of surrounding normal epithelial cells in response to the emergence of polarity-deficient cells. Furthermore, I also describe recent studies regarding the mechanism by which polarity-deficient cells are extruded from the tissue, and discuss future perspectives on the study of cell-cell communications in epithelial homeostasis.
