BACKGROUND The redox-active isoflavene anti-cancer drug, phenoxodiol, has previously been shown to inhibit plasma membrane electron transport and cell proliferation and promote apoptosis in a range of cancer cell lines and in anti-CD3/anti-CD28-activated murine splenocytes but not in non-transformed WI-38 cells and human umbilical vein endothelial cells. DESIGN AND METHODS We determined the e...
In anticipation of using single or fractionated hyperthermia treatment in ex vivo purging of leukemic bone marrow in the clinic, we have compared the hyperthermic sensitivity, kinetics of thermotolerance, and heat-shock protein synthesis in three human myelogenous leukemic cell lines. In terms of heat sensitivity, the chronic myelogenous leukemic cell line K562 was found to be the most resistan...

BACKGROUND Leukemic cells originate from hypoxic bone marrow, which protects them from anti-cancer drugs. Although many factors that cause drug resistance in leukemic cells have been studied, the effect of hypoxia on drug-induced apoptosis is still poorly understood. METHODS In this study, we examined the effect of hypoxia on anti-leukemic drug resistance in leukemic cell lines treated with c...
Modulation of Cell Behavior In Vitro by the Substratum in Fibroblastic and Leukemic Mouse Cell Lines
Peripheral blood mononuclear cells (PBMC) from 17 patients receiving HLA-identical sibling bone marrow grafts were stimulated with host pretransplant PBMC. Cytotoxic T-cell lines (TCL) with specificity for host pretransplant PBMC were obtained from 9 of these patients, all presenting with severe graft-versus-host disease (GVHD), but from none of the remaining cases lacking evidence of disease. ...
Hereditary deficiency of adenosine deaminase (ADA) usually causes profound lymphopenia with severe combined immunodeficiency disease. Cells from patients with ADA deficiency contain less than normal, and sometimes undetectable, amounts of ADA catalytic activity and ADA protein. The molecular defects responsible for hereditary ADA deficiency are poorly understood. ADA messenger RNAs and their tr...
