O6-Methylguanine DNA methyltransferase (MGMT; DNA alkyltransferase) cleaves both methyl and ethyl adducts from guanine bases on the DNA structure. Two major nucleotide excision repair pathways, transcription-coupled repair (TCR) and global repair (GR), are well known to remove cisplatin-induced DNA adducts. TCR acts on the transcribed strands Formation and repair of DNA adducts in vinyl chloride- and vinyl fluoride-induced carcinogenesis.

Tolerance and Repair of Lipid Peroxide DNA Adducts The major DNA adduct produced by the reaction of various lipid hydroperoxides with DNA is the N2 -dG adduct where the fatty acid-derived chain points into the minor groove of the DNA helix. Although this type of lesion can be repaired by NER [106,249], such a repair is not very efficient.

toxicity and repair of dna adducts produced by the natural product yatakemycin elwood a Mullins, rongxin shi & Brandt F eichman* Yatakemycin (YTM) is an extraordinarily toxic DNA alkylating agent with potent antimicrobial and antitumor properties and is the most recent addition to the CC-1065 and duocarmycin family of natural products. Taken together with our recent data on B[a]P-DNA adducts (20), it seems that the DNA repair system differentiates between adduct structure and conformation in the process of repairing DNA damage resulting from PAH diol epoxides.The finding that DB[a,l]PDE-dA adducts are the major adducts formed in mouse skin DNA in vivo is in agreement with an earlier study performed in MCF-7 cell cultures DNA repair mitigates the deleterious effects of DNA damage.

DNA repair mitigates the deleterious effects of DNA damage.

Diverse chemical sources, structures and biological consequences are associated with DNA adduct formation. Furthermore, when considering DNA ably repaired by homologous recombinational repair. To extend our work, we investigated whether fludarabine inhibits nucleotide excision repair (NER) of CDDP-induced DNA intrnstrand adducts.

2016-10-11 OSTI.GOV Conference: Enzymology of repair of DNA adducts produced by N-nitroso compounds individual DNA adducts, such as those induced by exposures to AFB 1-exo-8,9-epoxide, to be situated at defined sites in the E. coli virus M13mp8 (39). 1-N7-dG adduct is a substrate for nucleotide excision repair (50). Significantly, DNA damage frequently involves the "flipping" of damaged bases DNA–topoisomerase adducts are toxic lesions that result from normal cell physiology and chemotherapeutic treatments with topoisomerase inhibitors. These lesions block RNA transcription and DNA replication and must be removed to preserve genomic integrity and cell homeostasis. 1985-10-01 can lead to the formation of DNA adducts.

5. Repair Pathways for Pyridyloxobutyl DNA Adducts. DNA adduct repair protects a cell against the toxic and genotoxic effects of DNA damage. There are multiple pathways involved in the removal of alkylated DNA bases generated by reactive alkanediazohydroxides. 30 DNA DAMAGE AND REPAIR: INTERSPECIES COMPARISONS heterogeneity of adduct disttibution and processing, and the role of the adducts in oncogene activation.
