Mechanism and pharmacological specificity of dUTPase-mediated protection from DNA damage and cytotoxicity in human tumor cells
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 1998-09)
Purpose : We have reported previously that the expression of E. coli dUTPase (dutE) can protect HT29 cells from 5-fluorodeoxyuridine (FdUrd)-induced DNA fragmentation and cytotoxicity. In the study reported here, we further ...
Augmentation of hepatic doxorubicin extraction with extracorporeal filtration avoids the dose-dependent, nonlinear increase in AUC observed with systemic administration
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 1997-12)
Purpose : Regional therapy of primary or metastatic liver cancer with low hepatic extraction ratio drugs such as doxorubicin is constrained by development of systemic toxicity. To examine the effect of augmentation of ...
Combination vinorelbine and capecitabine for metastatic breast cancer using a non-body surface area dosing scheme
(Springer-Verlag, 2006-07)
Purpose : This study sought to determine the maximum tolerated dose of flat-dosed vinorelbine in combination with capecitabine in patients with metastatic breast cancer. At the time of study initiation, it was anticipated ...
The effect of vehicle on the tissue distribution profiles of radioiodinated cholesterol esters in the rat
(Elsevier, 1981)
Several groups have examined the possible use of radioiodinated cholesterol esters to achieve selective uptake of radioactivity in the adrenal cortex and have obtained variable results. This study indicates that the tissue ...
Dependence of fluorodeoxyuridine-induced cytotoxicity and megabase DNA fragment formation on S phase progression in HT29 cells
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 1996-02)
The relationship between cell cycle progression and induction of DNA double-strand breaks and cytotoxicity by exposure to fluorodeoxyuridine (FdUrd) was studied in HT29 human colon cancer cells. Fractionation of drug-treated ...
Interaction between gemcitabine and mitomycin-C in vitro
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 2000-01)
Both gemcitabine (2′,2′-difluorodeoxycytidine; dFdCyd) and mitomycin-C (MMC) are active against several solid malignancies. dFdCyd is an attractive agent for use in combination with drugs which damage DNA and with radiation ...
Hepatic arterial chemotherapy for primary and metastatic liver cancers
(Springer-Verlag, 1989-01)
Hepatic arterial chemotherapy represents a means of selectively exposing hepatic tumor to cytotoxic agents. Although 5-fluoro-2′-deoxyuridine has been shown to generate a higher response rate in the treatment of colorectal ...
Response of human HT-29 colorectal tumor cells to extended exposure to bromodeoxyuridine
(Springer-Verlag, 1989-01)
Effects of the extended exposure of a human colorectal tumor-cell line (HT-29) to bromodeoxyuridine (BrdUrd) were studied in anticipation of the clinical use of that agent to treat colorectal cancer, particularly as a ...
Pharmacologic studies on the dibutyl and γ-monobutyl esters of methotrexate in the rhesus monkey
(Springer-Verlag, 1982-12)
The pharmacokinetics and metabolism of dibutyl methotrexate (DBMTX) and γ-monobutyl methotrexate (γ-MBMTX) were studied in Rhesus monkeys. When a bolus IV dose of either [ 3 H]DBMTX or [ 3 H]γ-MBMTX was given, the principal ...
Prediction of thioguanine-induced cytotoxicity by dual-parameter flow cytometric analysis
(Springer-Verlag, 1989-10)
A method is presented for the quantitative analysis of delayed cytokinetic effects resulting from the treatment of L1210 cells with 6-thioguanine (TG). By using dual-parameter (DNA/protein) flow cytometry, we could observe ...
