The cellular function of kinases combined with the difficulty of designing selective small molecule kinase inhibitors (SMKIs) poses a challenge for drug development. The late-stage attrition of SMKIs could be lessened by integrating safety information of kinases into the lead optimization stage of drug development. Herein, a mathematical model to predict bone marrow toxicity (BMT) is presented ...

In a consecutive entry trial, the incidence and time course of decreased neutrophil function was assessed in 20 patients treated with allogeneic bone marrow transplantation (BMT). The aim of the study was to assess the prognostic value of low neutrophil function for late pyogenic infections. Chemotaxis, superoxide production, and phagocytic-bactericidal activity were studied before and 2,6,9, a...

Major symptoms of diabetes mellitus manifest, once pancreatic β-cell numbers have become inadequate. Although natural regeneration of β-cells after injury is very limited, bone marrow (BM) transplantation (BMT) promotes their regeneration through undetermined mechanism(s) involving inter-cellular (BM cell-to-β-cell) crosstalk. We found that two microRNAs (miRNAs) contribute to BMT-induced β-cel...

Preclinical models have shown that transplantation of marrow mesenchymal cells has the potential to correct inherited disorders of bone, cartilage, and muscle. The report describes clinical responses of the first children to undergo allogeneic bone marrow transplantation (BMT) for severe osteogenesis imperfecta (OI), a genetic disorder characterized by defective type I collagen, osteopenia, bon...

Hemopoietic stem cells (HSCs) can be harvested from the bone marrow, peripheral blood or umbilical cord blood. HSC transplantation is used to treat hematologic and lymphoid cancers and other disorders. Some reports have indicated that Bone Marrow Transplantation (BMT) might cure these intractable diseases--including hematological disorders, autoimmune diseases and age-associated diseases. Intra...

Using OKT3 monoclonal antibody as a mitogen, we have studied interleukin 2 (IL2) production and proliferation in peripheral blood mononuclear cells (PBMC) of 23 patients receiving bone marrow transplants. Twenty patients were recipients of allogeneic bone marrow for treatment of hematologic malignancies, aplastic anemias (AA), or severe combined immunodeficiencies (SCID). Three patients with Ho...

Acute graft-versus-host disease (GVHD). a major complication of allogeneic bone marrow transplantation (BMT). is probably mediated by T lymphocytes present in the marrow graft. In this study. the repopulation of the peripheral blood with T4 and T8 T cells was investigated during the period preceding the occurrence of acute GVHD. Twentyfour allogeneic and 1 1 autologous BMT recipients were monit...

Chronic myelocytic leukemia (CML) may display a lymphoproliferative phase (lymphoid blast crisis) that is generally of B cell phenotype. Since lymphoproliferative disorders may occur following bone marrow transplantation (BMT), it may be difficult to distinguish posttransplant relapse of CML lymphoid blast crisis from de novo lymphoproliferation. Lymphoid blast crisis cells from a patient with ...

Increasingly, bone marrow transplant (BMT) is the treatment of choice for certain hematologic diseases. BMT is, however, a risky procedure with many potentially serious complications. Some complications are the result of the conditioning regimen, a stage of transplantation that includes large doses of chemotherapy and/or radiation therapy. Conditioning-induced neutropenia and thrombocytopenia o...

Bone marrow transplantation (BMT) is often followed by significant morbidity and mortality due to protracted immunodeficiency. We have hypothesized that the bone marrow-ablative regimen may delay the recovery of normal immune function following transplantation by impairing the interaction of host endothelial cells with circulating graftderived lymphocytes. This report compares the relative effe...
