Effects of Mitomycin C on Human Chromosomes
Mitomycin C (MC) is a chemically reactive antibiotic derived from Streptomyces caespitosus. The drug selectively inhibits DNA synthesis (2, 15, 29, 34, 39, 40, 43, 44, 49) and degrades cellular DNA but does not affect the synthesis of R N A or protein (31, 33, 40). MC induces bacteriophage production in lysogenic bacteria (23, 29), increases the rate of genetic recombination among mutant forms ...
متن کاملIn vitro effects of mitomycin-C on human keratocytes.
BACKGROUND The purpose of the present study is to quantify the in vitro antiproliferative and cytotoxic effects of mitomycin-C on human keratocytes for their potential to modulate corneal stromal wound healing. METHODS Cultured human keratocytes were exposed to various concentrations of mitomycin-C for periods of 5 minutes and 1 hour. Keratocyte proliferation and viability were assessed by ph...
متن کاملEffects of BMY 25282, a mitomycin C analogue, in mitomycin C-resistant human colon cancer cells.
BMY 25282, a newly designed analogue of mitomycin C (MMC), was assessed for its non-cross-resistant cytotoxic and biochemical action against MMC-resistant human colon carcinoma cells. The analogue has an amidine substituted at position 7 of MMC and has a more efficient intracellular activation to its active species than MMC. In this study we demonstrated that BMY 25282 can overcome MMC resistan...
متن کاملEffects of Mitomycin C on Crossing over in Drosophila Melanogaster.
RECENT evidence indicates that a large proportion of increases in crossing over induced in Drosophila melanogmter females is of gonia1 ongin (WHITTINGHILL 1955; THOMPSON 1964; SUZUKI 1965). HOLLIDAY (1964) and ESPOSITO and HOLLIDAY (1964) find that treatment of Ustilago and Saccharomyces with agents that inhibit DNA replication (mitomycin C, 5-fluorodeoxyuridine) results in increased somatic re...
متن کاملEffects of caffeine on L-cells exposed to mitomycin C.
Mouse L-cells were grown in suspension culture and exposed to varying concentrations, from 0.2 to 4 ¿ig/ml,of mitomycin C for periods ranging from 0.5 to 3.5 hr. A plot of cell colony-forming ability versus concentration of mitomycin C for different times of exposure yielded a series of exponential survival curves which were related by the fact that the product of the time of exposure and the ...
