A newly discovered molecule may help defeat one of cancer therapy’s biggest challenges: drug resistance. By dismantling the cellular machinery that repairs DNA, it made resistant tumors vulnerable to treatment once again. Credit: AI/ScienceDaily.com 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
