JNK and Yorkie drive tumor progression by generating polyploid giant cells in Drosophila.

Abstract excerpt

Epithelial cancer tissues often possess polyploid giant cells, which are thought to be highly oncogenic. However, the mechanisms by which polyploid giant cells are generated in tumor tissues and how such cells contribute to tumor progression remain elusive. We previously noticed in Drosophila imaginal epithelium that cells mutant for the endocytic gene rab5 exhibit enlarged nuclei. Here we find that mutations in...
