Here, we use a large-scale cell line-based approach to identify cancer cell-specific mutations that are associated with DNA-dependent protein kinase catalytic subunit (DNA-PKcs) dependence. For this purpose, we profiled the mutational landscape across 1,319 cancer-associated genes of 67 distinct cell lines and identified numerous genes involved in(More)
Chronic lymphocytic leukemia (CLL) is the most common form of leukemia in the Western world and accounts for approximately 30% of adult leukemias and 25% of non-Hodgkin lymphomas. The median age at diagnosis is 72 years. During recent years numerous genetic aberrations have been identified that are associated with an aggressive course of the disease and(More)
Diffuse large B-cell lymphoma (DLBCL) is the most common type of aggressive lymphoma in the Western world and remains a clinical challenge. Two types of DLBCL are distinguishable, namely a germinal center B-cell-like phenotype (GCB) and an activated B-cell-like phenotype (ABC). Particularly ABC-DLBCL is difficult to treat, as this subentity typically(More)
Treatment resistance becomes a challenge at some point in the course of most patients with chronic lymphocytic leukemia (CLL). This applies to fludarabine-based regimens, and is also an increasing concern in the era of more targeted therapies. As cells with low-replicative activity rely on repair that triggers checkpoint-independent noncanonical pathways,(More)
Defects in maintaining genome integrity are a hallmark of cancer. The DNA damage response kinase ATM is frequently mutated in human cancer, but the significance of these events to chemotherapeutic efficacy has not been examined deeply in whole organism models. Here we demonstrate that bi-allelic Atm deletion in mouse models of Kras-mutant lung(More)
