Excessive E2F Transcription in Single Cancer Cells Precludes Transient Cell-Cycle Exit after DNA Damage

Abstract

Graphical Abstract Highlights d Individual cycling cancer cells display enhanced E2F target gene expression d E2F7/8 deletion or E2F3 overexpression overrides cell-cycle exit after DNA damage d Elevated levels of the E2F target Emi1 prevent DNA-damage-induced cell-cycle exit d The cell-cycle exit after DNA damage is transient and leads to endoreplication
