SMARCA4 Loss Increases RNA Polymerase II Pausing and Elevates R-Loops to Inhibit BRCA1-Mediated Repair in Ovarian Cancer
Pol II stalling induced by SMARCA4 loss leads to R-loop accumulation that sequesters BRCA1 to transcription complexes, underlying the sensitivity of SMARCA4-deficient ovarian cancers to inhibitors targeting PARPs and Pol II elongation.
