RNA Pol II Degradation Triggers Apoptosis Beyond Transcripti
2026-04-27
Harper et al. (2025) reveal that cell death following RNA Pol II inhibition is not simply due to loss of transcription, but is activated by a dedicated apoptotic signaling pathway sensing loss of the hypophosphorylated RNA Pol IIA subunit. This paradigm-shifting discovery uncovers a mitochondria-linked cell death mechanism, informing both fundamental biology and strategies for optimizing apoptosis induction in cancer research.
