KW-2149 is a new water-soluble analogue of mitomycin C which shows a broad spectrum antitumor activity in experimental tumor models including mitomycin C-resistant tumors and is less hematotoxic than mitomycin C. We have found that KW-2149 increases protein-DNA complexes in HeLa S3 cells using the potassium/sodium dodecyl sulfate precipitation method which recovers largely DNA bound covalently ...

NAD(P)H:quinone oxidoreductase 1 / (NQO1 / ), NQO1 along with NRH:quinone oxidoreductase 2 / (NQO2 / ), and wild-type (WT) mice were exposed to five once weekly doses of mitomycin C. The mice were euthanized 15 weeks after the first dose. Blood cell counts and histologic analyses were done. WT and NQO2 / mice showed hypocellularity and a significant increase in adipocytes in bone marrow. They a...

AIMS A prospective, randomised, double blind, placebo controlled study of intraoperative mitomycin C as adjunctive treatment of primary pterygium was conducted. METHODS A total of 66 eyes of 54 patients with primary pterygium were treated with excision, with or without a single intraoperative application of mitomycin C (0.1 mg/ml for 5 minutes) to evaluate the efficacy and toxicity of this ad...

PURPOSE Based on our previous report that showed enhanced transfer of mitomycin C to the sclera and the conjunctiva by dissolving the agent into a reversible thermo-setting gel, we conducted a study to investigate the efficacy of mitomycin C gel in the rabbit. METHODS We subconjunctivally injected 0.1 mL of the mitomycin C gel solution containing several different amounts of the agent. Trephi...

Over the years, mitomycin C has been used by refractive surgeons to prophylactically decrease haze after surface ablation procedures and therapeutically in the treatment of preexisting haze. Development of mitomycin C treatments has had a significant role in the revival of surface ablation techniques. We reviewed the literature regarding mechanism of action of mitomycin C, its role in modulatin...

Introduction Mitomycin C is an anticancer antibiotic agent that has the potential for broad-spectrum use against several cancers, including mammary cancers. Because its half-life is 17 min after a 30 mg intravenous bolus administration, the suitability of mitomycin C for wide use in the clinical setting is limited. Based on tumor pathophysiology, pH-sensitive liposomes could provide better tumo...

A temperate phage designated obeta1 (omicron beta) was mitomycin C induced and isolated from heat-labile enterotoxin (LT)-producing Escherichia coli E2631-C2. Phage obeta1 infected the nonlysogenic, nontoxigenic, mitomycin C-sensitive strain of E. coli K-12 (CSH38) and converted it to lysogeny and enterotoxigenicity. After the establishment of lysogeny, E. coli CSH38(obeta1) produced produced L...

purpose: to determine the efficacy and safety of subconjuctival injection of mitomycin c versus daunorubicin for treatment of pterygium. methods: this randomized double blind placebo-controlled clinical trial included 54 eyes of 36 patients with pterygium who were referred to al-zahra hospital, zahedan-iran in 2004. eyes were randomly assigned to three groups including mitomycin c, daunorubicin...

We have observed the selective toxicity of mitomycin C toward hypoxic as compared to aerobic cells in vitro for three established cell lines (Chinese hamster ovary, Chinese hamster V-79, and human HeLa) and for cells from the transplantable KHT murine tumor. The magnitude of the selective toxicity was cell line dependent. We have studied the in vivo effects of mitomycin C against aerobic and hy...
