Dual targeting of the proteasome regulates survival and homing in Waldenstrom macroglobulinemia.
Waldenström macroglobulinemia (WM) is an incurable low-grade B-cell lymphoma characterized by high protein turnover. We dissected the biologic role of the proteasome in WM using 2 proteasome inhibitors, NPI-0052 and bortezomib. We found that NPI-0052 inhibited proliferation and induced apoptosis in WM cells, and that the combination of NPI-0052 and bortezomib induced synergistic cytotoxicity in...
متن کاملThe Akt pathway regulates survival and homing in Waldenstrom macroglobulinemia.
Waldenstrom macroglobulinemia (WM) is an incurable low-grade lymphoplasmacytic lymphoma. We demonstrate up-regulated Akt activity in WM, and that Akt down-regulation by Akt knockdown and the inhibitor perifosine leads to significant inhibition of proliferation and induction of apoptosis in WM cells in vitro, but not in normal donor peripheral blood and hematopoietic progenitors. Importantly, do...
متن کاملWaldenström macroglobulinemia.
Waldenström macroglobulinemia is a lymphoplasmacytic lymphoma. A serum monoclonal IgM protein is required to establish this diagnosis. The clinical features patients develop include normochromic normocytic anemia, thrombocytopenia, hepatosplenomegaly, lymphadenopathy and signs of hyperviscosity. The International Staging System for Waldenström macroglobulinemia divides patients prognostically ...
متن کاملExtramedullary Waldenström macroglobulinemia.
Disease assessment in Waldenstrom Macroglobulinemia (WM) is dependent on the percent involvement of B-cell neoplasm in the bone marrow and IgM paraprotein in the serum. A subset of patients also demonstrates extramedullary involvement, which is infrequently examined. The role of extramedullary involvement in the diagnosis and prognosis of WM is poorly understood. The purpose of this study is to...
متن کاملBiology, prognosis, and therapy of Waldenström Macroglobulinemia.
Waldenström Macroglobulinemia (WM) is a rare B-cell lymphoma characterized by the uncontrolled accumulation of malignant lymphoplasmacytic cells, mainly in the bone marrow, and monoclonal IgM production. Despite its rarity, our understanding of the biology of this disease has improved significantly in recent years with the identification of recurrent mutations in the MYD88 and CXCR4 genes. Base...
