Mutant p53 Directs PARP to Regulate Replication Stress and Drive Breast Cancer Metastasis

Gu Xiao, George K. Annor, Katherine W. Harmon…·Jill Bargonetti

This study shows mutant p53 uses its C-terminal domain to reprogram PARP activity, enabling replication stress adaptation and metastasis in TNBC, and identifies mtp53 as a biomarker for PARP inhibitor and DNA-damaging therapy.

A CANCER PERSISTENT DNA REPAIR CIRCUIT DRIVEN BY MDM2, MDM4 (MDMX), AND MUTANT P53 FOR RECRUITMENT OF MDC1 AND 53BP1 TO CHROMATIN

Viola Ellison, Alla Polotskaia, Gu Xiao…·Jill Bargonetti

This study identifies a cancer persistent DNA repair circuit involving mtp53, MDM2, and MDMX that recruits 53BP1 and MDC1 to chromatin, enhancing cell survival.
