RNA Pol II Inhibition Triggers Apoptosis Beyond Transcriptio
2026-07-13
Harper et al. (2025) demonstrate that cell death following RNA polymerase II (Pol II) inhibition is not a passive consequence of transcriptional silencing but is instead an actively signaled apoptotic process initiated by the loss of hypophosphorylated RNA Pol IIA. This finding redefines the mechanistic understanding of apoptosis in the context of transcriptional inhibition and has broad implications for cancer biology and the interpretation of drug action.
