Mitomycin C is an antineoplastic antibiotic by inhibiting DNA synthesis, used to treat different cancers. Mitomycin C induces apoptosis in a caspases-dependent and Fas/CD95-independent manner. In vitro
Mitomycin C, by inducing DNA interstrand crosslinks, physically blocks DNA replication, recombination, and RNA transcription. [1] Mitomycin C potentiates TRAIL-induced apoptosis in HCT116 (p53-/-) colon cancer cells and sensitizes TRAIL-resistant colon cancer cells HT-29 to the cytokine by through JNK-independent upregulation of death receptors. [2] In different human cancer cell lines, such OVCAR-5 (ovary), HT-29 (colon), SK-N-MC (neuroblastoma), HEP-2 (liver), COLO-205 (colon), NIH-OVCAR-3 (ovary) and A-549 (lung) cells, Mitomycin C shows cytotoxic activity.
In vivo
As the clinical first choice in superficial bladder tumors, in a rat bladder tumor model, Mitomycin C (400 μM) significantly prevents intravesical tumor growth. Cell Data
