The optimal schedule for 5-fluorouracil radiosensitization in colon cancer cell lines.
To evaluate the optimal schedule of 5-fluorouracil (5-FU) radiosensitization in rectal cancer, we investigated the interaction between radiation and several doses of 5-FU on colon cancer cell lines based on pharmacokinetics of oral fluoropyrimidine. Cellular cytotoxicity in colon cancer cell lines, LoVo, WiDr and Caco-2 was determined, using a WST-8 colorimetric assay, after 24 h exposure to se...

objective: the purpose of this study was to observe the effects of methoxyamine (mx) on the cytotoxic effects and dna damage caused by 5-fluorouoracil (5-fu), in combination with gamma-rays in human colon cancer cell line. materials and methods: in this experimental study, ht29 cells were cultured as a monolayer and treated with different concentrations of 5-fu along with 1 mm mx for 24 h. afte...
متن کاملSchedule-dependent cytotoxicity of methotrexate and 5-fluorouracil in human colon and breast tumor cell lines.
The effect of sequential methotrexate and 5-fluorouracil on the clonal growth of the human colon adenocarcinoma cell, HCT-8, and the hormone-dependent human breast carcinoma cell, 47-DN, was examined. In both cell lines, when 5-fluorouracil was given during the last 6 h of a 24 h methotrexate exposure period, there was marked synergistic inhibition of clonal growth. Shorter intervals or the rev...

OBJECTIVE This study intended to observe the effects of methoxyamine (Mx) on cytotoxic effects and DNA damage caused by 5-Fluorouracil (5-FU) in combination with gamma radiation in a human colon cancer cell line, HT29. MATERIALS AND METHODS In this experimental study, HT29 cells were cultured as a monolayer and treated with different concentrations of 5-FU along with 1 mM Mx for 24 hours. Nex...
متن کاملSchedule dependency of 5-fluorouracil.
5-Fluorouracil (5-FU) is cell-cycle specific for its cytotoxicity and has a pharmacokinetic profile characterized by a short, single-dose half-life of 10 to 20 minutes in plasma. Efforts to maximize its clinical efficacy have been directed at overcoming this short half-life. Strategies have included prolonging intracellular exposure by biochemical modulation or administration by infusional sche...
