Mitomycin C and decarbamoyl mitomycin C induce p53-independent p21WAF1/CIP1 activation
Mitomycin C (MC), a commonly used anticancer drug, induces DNA damage via DNA alkylation. Decarbamoyl mitomycin C (DMC), another mitomycin lacking the carbamate at C10, generates similar lesions as MC. Interstrand cross-links (ICLs) are believed to be the lesions primarily responsible for the cytotoxicity of MC and DMC. The major ICL generated by MC (α-ICL) has a trans stereochemistry at the gu...
متن کاملDecarbamoyl mitomycin C (DMC) activates p53-independent ataxia telangiectasia and rad3 related protein (ATR) chromatin eviction
Interstrand crosslinks induce DNA replication fork stalling that in turn activates the ATR-dependent checkpoint and DNA repair on nuclear chromatin. Mitomycin C (MC) and Decarbamoyl Mitomycin C (DMC) induce different types of DNA crosslinks with DMC being a more cytotoxic agent. We previously reported that the novel DMC induced β-interstrand DNA crosslinks induce a p53-independent form of cell ...
متن کاملTopical Mitomycin C and Radiation Induce Conjunctival DNA-Polyploidy
INTRODUCTION Atypical cell changes often occur following treatment of premalignant or malignant conjunctival neoplasias with topical mitomycin C (MMC) and/or radiation. These reactive, non-neoplastic alterations of the conjunctival epithelium can be a differential diagnostic problem. Our aim was to investigate changes in the nuclear DNA-distribution of conjunctival epithelial cells after MMC- a...
متن کامل[Mitomycin C and excimer laser].
Mitomycin C is an antimetabolite agent that blocks DNA and RNA replication and protein synthesis. It has been used in several ophthalmologic areas, and recently as a modulator of corneal wound healing in excimer laser surgeries. A single application of mitomycin C during surface corneal photoablative surgery seems a safe and efficient therapeutic option for eyes with corneal opacity and/or as p...
متن کاملMitomycin-C Use in Ophthalmology
Mitomycin-C is a chemotherapeutic drug that acts by inhibiting DNA synthesis. Its use and application in ophthalmology has been increasing in recent years because of its mandatory effects on wound healing. Current applications include pterygium surgery, glaucoma surgery, corneal refractive surgery, cictracial eye disease, conjunctivalneoplasia, dacryocystorhinostomy surgeries and allergic eye d...
