New data reveal that LINP1, a lncRNA overexpressed in triple-negative breast cancer, interacts with the Ku70–Ku80 complex and DNA-PKcs, thereby promoting NHEJ-mediated DNA double-strand-break repair. Long noncoding RNAs (lncRNAs) play critical roles during tumorigenesis by functioning as scaffolds t...
