RNA Pol II Inhibition Triggers Apoptosis via PDAR, Not mRNA
2026-04-30
Harper et al. (2025) reveal that inhibition of RNA polymerase II (RNA Pol II) induces apoptosis through an active signaling pathway, independent of transcriptional shutdown. Their work identifies loss of hypophosphorylated RNA Pol IIA as the key trigger for cell death, overturning previous assumptions about passive mRNA decay as the main driver and highlighting mitochondrial signaling's pivotal role.
