Platinum-based chemotherapy robustly induces nuclear F-actin assembly in ovarian cancer cells, and this response is driven by the p38α MAPK–MK2 signaling axis.
- Why it matters: Nuclear F-actin supports DNA damage repair and chemoresistance, but the upstream regulators that control its dynamic polymerization after genotoxic stress are not well defined.
- What they did: The study built nFANet, a deep learning pipeline for high-throughput nuclear F-actin detection, then combined it with kinome screening to pinpoint p38α MAPK and MK2 and test formin-mediated assembly.
- The result: Pharmacological inhibition or genetic knockout of the p38α MAPK–MK2 pathway sensitized ovarian cancer cells to platinum-based therapy, enabling subgroup-focused therapeutic targeting.
