Complex interplay between p53 and chromosome stability.
2021
TP53-dependent cell cycle arrest has been proposed to limit the proliferation of aneuploid cells. We investigated the cellular response to aneuploidy in cell lines and organoid cultures and found that TP53 (also known as p53) is not activated following aneuploidy induction in organoids. However, we confirmed that p53 is required for high mitotic fidelity. Our findings provide a revised view on how p53 safeguards against aneuploidy.
