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)
The adaptor protein MYD88 is critical for relaying activation of Toll-like receptor signaling to NF-κB activation. MYD88 mutations, particularly the p.L265P mutation, have been described in numerous distinct B-cell malignancies, including diffuse large B-cell lymphoma (DLBCL). Twenty-nine percent of activated B-cell-type DLBCL (ABC-DLBCL), which is(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)
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)
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)
This is a report of 47 followed-up children in whom open intramedullary splinting of the medullary space was effected because of fracture of the shaft of the femur, using the rush-pinning technique developed by the authors. In 33 children, a slight increase of longitudinal growth was seen, which amounted to 2-20 mm. The average longitudinal extension was(More)
Chronic lymphocytic leukemia (CLL) remains an incurable disease. Two recurrent cytogenetic aberrations, namely del(17p), affecting TP53, and del(11q), affecting ATM, are associated with resistance against genotoxic chemotherapy (del17p) and poor outcome (del11q and del17p). Both del(17p) and del(11q) are also associated with inferior outcome to the novel(More)
