Genome stability disrupted by the circRBM39(4,5,6)-RPA2 axis represses breast tumorigenesis.
Genome instability (GI) is a hallmark of cancer. GI is associated with accumulative DNA damage and tumor-specific defects in DNA repair. Multiple antitumor drugs have been developed to promote persistent GI and to drive DNA damage beyond a threshold that tumor cells can survive. However, regulatory roles of circular RN...
