Scientists shut down cancer DNA repair to overcome drug resistance
Researchers have identified a small molecule, UNI418, that disrupts the DNA repair machinery in cancer cells, potentially overcoming drug resistance. By activating a protein disposal pathway, the treatment leaves cancer cells unable to repair genetic damage.
Why it matters
This discovery offers a promising new strategy to combat treatment-resistant cancers, which are a major hurdle in oncology.
Cancer cells have a remarkable ability to survive treatments that damage their DNA. One reason is that they rely on sophisticated repair systems that can fix genetic damage that would otherwise kill them. Among the most important of these systems is homologous recombination, a highly accurate DNA repair process that depends on proteins such as RAD51 and CHK1.
