Fig. 7. CENP-A overexpression promotes distinct cell fates depending on p53 status.

Fig. 7

CENP-A overexpression reprograms cell fate with distinct effects on cell state and cell identity that depend on p53 status. Perturbation (a) by CENP-A overexpression (in blue) induces mitotic defects in both wild-type p53 (p53-WT, top panel blue) and p53-defective cells (p53-DN, dominant negative, bottom panel green). These defects provoke distinct cell fate decisions according to p53 status, impacting cell state (b) or identity (c). When p53 is functional, cell state shifts toward acute cell cycle arrest and senescence, reducing self-renewal capacity. Additional stress, like DNA damage from X-irradiation, amplifies this response, resulting in radiosensitivity. Furthermore, functional p53 ensures the preservation of epithelial identity. In contrast, when p53 is defective, the cells evade arrest and continue cycling, allowing CENP-A overexpression to promote epithelial–mesenchymal transition (EMT). * symbol: reprogramming stimulated by CENP-A overexpression.
