The primary purpose of this study was to evaluate the effect of CYP2C8*3 and three genetic ABCB1 variants on the elimination of paclitaxel. We studied 93 Caucasian women with ovarian cancer treated with paclitaxel and carboplatin. Using sparse sampling and nonlinear mixed effects modeling, the individual clearance of unbound paclitaxel was estimated from(More)
The p53 tumor suppressor protein inhibits the formation of tumors through induction of cell cycle arrest and/or apoptosis. In the present study we demonstrated that p53 is also a powerful inhibitor of human telomerase reverse transcriptase (hTERT), a key component for telomerase. Activation of either exogenous temperature-sensitive (ts) p53 in BL41 Burkitt(More)
The receptor-mediated degradation of 125I-low density lipoprotein (LDL) was compared in normal white blood cells and leukemic cells. The cells were isolated from the peripheral blood and bone marrow of healthy subjects and patients with newly diagnosed leukemia. The cells from most of the 40 consecutive patients with acute myelogenous leukemia showed(More)
PURPOSE P-glycoprotein, encoded by the mdr-1 gene, confers multidrug resistance to a variety of antineoplastic agents, e.g., paclitaxel. Recently, different polymorphisms in the mdr-1 gene have been identified and their consequences for the function of P-glycoprotein, as well as for the treatment response to P-glycoprotein substrates, are being clarified.(More)
59 patients with acute leukaemia were examined to see if hypocholesterolaemia, which is commonly found in acute leukaemia, was due to the high low-density-lipoprotein (LDL)-receptor activity of leukaemic cells. LDL-receptor activity was found to be inversely correlated with plasma-cholesterol concentration. Patients with both a high LDL-receptor activity(More)
In 95 leukaemic cell samples from 66 patients with acute myelogenous leukaemia (AML) (47 de novo and 19 secondary AML) telomerase activity was determined and the expression of the telomerase components: telomerase reverse transcriptase (hTERT), telomerase RNA template (hTR) and telomerase-associated protein (TP1) evaluated by RT-PCR. Compared to peripheral(More)
This study examined the role of thiopurine methyltransferase (TPMT) polymorphism in the metabolism and clinical effects of azathioprine and 6-mercaptopurine in the treatment of inflammatory bowel disease and childhood leukemia. The current hypothesis is that the cytotoxic effects of thiopurines are caused by the incorporation of thioguanine nucleotides into(More)
The purpose of this study was to evaluate the role of sequence variants in the CYP2C8, ABCB1 and CYP3A4 genes and the CYP3A4 phenotype for the pharmacokinetics and toxicity of paclitaxel in ovarian cancer patients. Thirty-eight patients were treated with paclitaxel and carboplatin. The genotypes of CYP2C8*1B, *1C, *2, *3, *4, *5, *6, *7, *8 and P404A, ABCB1(More)
Anthracycline antibiotics are widely used as anticancer agents. Idarubicin (4-demethoxydaunorubicin; Ida), a semisynthetic derivative of daunorubicin (Dnr) is more potent than the parent compound in vitro and in vivo. The equitoxic dose of Ida in patients is about one-fourth of that of Dnr. We compared these drugs regarding cytotoxicity, apoptosis(More)
