Characterization of a RAD51C-Silenced High Grade Serous Ovarian Cancer Model During PARP Inhibitor Resistance Development

R. M. Hurley, C. D. McGehee, K. Nesic, C. Correia, T. M. Weiskittel, R. L. Kelly, A. Venkatachalam, X. Hou, N. M. Pathoulas, X. W. Meng, O. Kondrashova, M. R. Radke, P. A. Schneider, K. S. Flatten, K. L. Peterson, , S. H. Kaufmann

This study shows that PARPi treatment can reverse RAD51C promoter methylation and restore expression in a high-grade serous ovarian cancer model, while maintaining platinum sensitivity.

Acquired RAD51C promoter methylation loss causes PARP inhibitor resistance in high grade serous ovarian carcinoma

K. Nesic, O. Kondrashova, R. M. Hurley, C. McGehee, C. J. Vandenberg, G.-Y. Ho, E. Lieschke, G. Dall, N. Bound, K. Shield-Artin, M. R. Radke, A. Musafer, Z. Qing Chai, M. R. Eftekhariyan Ghamsari, M. I. Harrell, , C. L. Scott

This study shows that loss of RAD51C promoter methylation leads to PARP inhibitor resistance in high-grade serous ovarian carcinoma, independent of BRCA1 methylation status.

Inhibition of RNA Polymerase I Transcription Activates Targeted DNA Damage Response and Enhances the Efficacy of PARP Inhibitors in High-Grade Serous Ovarian Cancer

E. Sanij, K. M. Hannan, S. Yan, X. Xuan, J. E. Ahern, K. T. Chan, J. Son, O. Kondrashova, E. Lieschke, M. J. Wakefield, A. S. Trigos, D. Frank, S. Ellis, C. Cullinane, J. Kang, , R. B. Pearson

This study shows CX-5461, an RNA polymerase I inhibitor, enhances PARP inhibitor efficacy in HR-deficient HGSOC by inducing replication stress and DNA damage, overcoming resistance mechanisms.
