The Nordic Myeloma Study Group conducted an open randomized trial to compare bortezomib as consolidation therapy given after high-dose therapy and autologous stem cell transplantation (ASCT) with no consolidation in bortezomib-naive patients with newly diagnosed multiple myeloma. Overall, 370 patients were centrally randomly assigned 3 months after ASCT to(More)
Glucocorticoids are fundamental drugs used in the treatment of lymphoid malignancies with apoptotic cell death as the hitherto proposed mechanism of action. Recent studies, however, showed that an alternative mode of cell death, autophagy, is involved in the response to anticancer drugs. The specific role of autophagy and its relationship to apoptosis(More)
Here, we identified caspase-2, protein kinase C (PKC)delta, and c-Jun NH2-terminal kinase (JNK) as key components of the doxorubicin-induced apoptotic cascade. Using cells stably transfected with an antisense construct for caspase-2 (AS2) as well as a chemical caspase-2 inhibitor, we demonstrate that caspase-2 is required in doxorubicin-induced apoptosis.(More)
BACKGROUND AND OBJECTIVES The mechanism of glucocorticoid -induced apoptosis is not fully understood and early predictive assays based on apoptotic markers for clinical outcome in acute lymphoblastic leukemia (ALL) are scarce. The aim of this study was to characterize the involvement of Bcl-2 family members and caspase activation in(More)
BACKGROUND Fine-needle aspiration (FNA) with immunophenotyping by immunocytochemistry (IC) on cytospins has recently received increased consideration in the diagnosis of lymphoma. The aim of our study was to establish the diagnostic value of a four-color flow cytometric (FCM) panel, including cytoplasmic Bcl-2, in cytologic diagnosis of malignant(More)
Glucocorticoids are fundamental drugs used in the treatment of lymphoid malignancies with apoptotic cell death as the hitherto proposed mechanism of action. We have recently shown that dexamethasone induces autophagy in lymphoid leukemia cells and in this particular setting this cell death modality is a prerequisite for the efficient killing of the leukemic(More)
Dendritic cells (DC) play a pivotal role in coordinating functions of the immune system. Little is known about DC levels in the bone marrow (BM) of patients receiving cytostatic treatment. We investigated DC levels by flow cytometry in BM at diagnosis, during and post-treatment in 76 children with acute lymphoblastic leukaemia (ALL). The levels of both(More)
Dendritic cells (DCs) develop in the bone marrow from haematopoietic progenitor cells. Two subsets, plasmacytoid DCs (pDCs) and myeloid DCs (mDCs), have been identified. Little is known regarding DC levels in bone marrow of patients with acute myeloid leukaemia (AML) before and after chemotherapy. We investigated relative pDC and mDC levels in bone marrow(More)
Multiple myeloma (MM) is a B-cell malignancy characterized by the expansion of clonal plasma blasts/plasma cells within the bone marrow that relies on multiple signaling cascades, including tyrosine kinase activated pathways, to proliferate and evade cell death. Despite emerging new treatment strategies, multiple myeloma remains at present incurable. Thus,(More)
Minimal residual disease (MRD) levels were determined by multi-parameter flow cytometry in 45 younger adult patients ( pound60 years old) with acute myeloid leukemia (AML) in complete remission. Data were collected after induction (MRD1; n=43) and/or at the end of post-remission chemotherapy or before stem cell transplantation (SCT)(MRD2; n=31). Patients(More)
