Rucaparib: PARP Inhibition Beyond BRCA
2026-09-17
Rucaparib (AG-014699) is a potent PARP1 inhibitor for dissecting DNA damage, repair deficiency, and radiosensitization. This article connects its established repair biology with SmD2-regulated splicing in hepatocellular carcinoma and translates that evidence into better assay decisions.

BH3 Mimetics in TP53-Wild-Type Breast Cancer
2026-09-17
A 2020 Cell Death & Differentiation study shows that chemotherapy-induced senescent breast cancer cells can retain a druggable dependence on antiapoptotic BCL-2 family proteins. In TP53-wild-type models, sequential treatment with chemotherapy and BH3 mimetics promoted tumor regression and extended survival in mice, supporting senolytic elimination of residual disease as a therapeutic strategy.

Piezo1, Matrix Stiffness, and DRG Axon Regeneration
2026-09-15
Lei and colleagues show that extracellular matrix stiffness regulates dorsal root ganglion axon regrowth through a Piezo1-dependent Ca2+–CaMKII–FAK–actin signaling axis. The study identifies stiffness as a context-dependent regulator rather than a simple linear stimulus and links Piezo1 suppression to improved sensory recovery after peripheral nerve injury.
