How to make cancer cells more sensitive to treatment. 💊

Preprint from Hasan Mamar & team shows that the loss of POLE4 - component of POLε - contributes to PARPi sensitivity, regardless of BRCA status.

POLE4: how to make cancer cells more sensitive to treatment

PARP inhibitors (#PARPi) resistance is ubiquitous in the clinic. A newly discovered pan-PARP inhibitor, thioparib, is highly effective against #olaparib -resistant cancer models, which suggests that therapeutic vulnerabilities still exist in PARPi-resistant tumors.
