Genetically unstable tetraploid cells can promote tumorigenesis. Recent estimates suggest that ∼37% of human tumors have undergone a genome-doubling event during their development. This potentially oncogenic effect of tetraploidy is countered by a p53-dependent barrier to proliferation. However, the cellular defects and corresponding signaling pathways that trigger growth suppression in tetraploid cells are not known. Here, we combine RNAi screening and in vitro evolution approaches to demonstra ...[more]
