Celecoxib Reprograms Cancer Chromatin to Double Chemotherapy Efficacy in Mice

Mouse model results that doubled chemotherapy efficacy have prompted plans for clinical translation of chromatin-modulating therapy.

Overview

  • Published July 22 in the Proceedings of the National Academy of Sciences, the study showed adding celecoxib to paclitaxel doubled tumor suppression in a mouse ovarian cancer model compared to chemotherapy alone.
  • The approach targets three-dimensional chromatin packing domains that store transcriptional memory and drive rapid treatment resistance.
  • A physics-based Chromatin-Dependent Adaptability model guided high-throughput screening of FDA-approved drugs, identifying the anti-inflammatory celecoxib as a transcriptional plasticity regulator.
  • Enhancing chemotherapy efficacy through chromatin reprogramming could enable lower, less toxic drug doses without compromising treatment outcomes.
  • Researchers are expanding their screening for more selective chromatin modulators and planning immune-competent studies to pave the way for human clinical trials.
