RNA Pol II Inhibition: Distinct Apoptotic Pathway Beyond Tra
2026-06-02
Harper et al. (2025) reveal that inhibition of RNA polymerase II triggers apoptosis via a signaling cascade initiated by the loss of hypophosphorylated RNA Pol IIA, rather than by passive mRNA decay. This discovery redefines the mechanistic basis for cell death in response to transcriptional inhibitors and has significant implications for the design and interpretation of apoptosis assays and epigenetic modulation strategies in oncology.
