In particular, we were intrigued by the finding that when endometrial DNA samples of women taking tamoxifen were analyzed, dG-N2-TAM adducts were detected at a frequency of 1.5–13.1 adducts/108 nucleotides in six Differential repair of platinum-DNA adducts in human bladder and testicular tumor continuous cell lines. Cancer Res. 1988 Jun 1; 48 (11):3019–3024. [Google Scholar] Eastman A, Schulte N. Enhanced DNA repair as a mechanism of resistance to cis-diamminedichloroplatinum(II). Biochemistry. 1988 Jun 28; 27 (13):4730–4734. DNA repair pathways are triggered to maintain genetic stability and integrity when mammalian cells are exposed to endogenous or exogenous DNA-damaging agents. The deregulation of DNA repair pathways is associated with the initiation and progression of cancer.

It is hypothesized that futile cycles of translesion synthesis past cisplatin-DNA adducts followed by removal of the newly synthesized DNA by an active mismatch repair system may lead to cell death. The variability in DNA repair capacity of the general population may depend in part upon common variants in DNA repair genes. X-ray repair cross complementing group 1 (XRCC1) is an important DNA base excision repair gene and exhibits polymorphic variation. Using the Long Island Breast Cancer Study Project, a population-based case-control study, we coli glycosylases excising analogous etheno adducts. DNA Repair 3: 1311–1321. 81. Habraken Y, Carter CA, Kirk MC, Ludlum DB. 1991.

DNA repair mitigates the deleterious effects of DNA damage. Nucleotide Excision Repair (NER) detects and removes bulky DNA adducts that disrupt base pairing and distort the DNA helix whereas Transcription-Coupled DNA Repair (TCR) removes DNA adducts that impede RNA polymerase elongation during gene expression. Se hela listan på sigmaaldrich.com repair pathways, among which nucleotide excision repair pathway constitutes the main mechanism to detect and repair cisplatin-induced DNA adducts6–8.

Glob J Pharmaceu Sci. 2017; 3(2): 002 555613. molecule’s regular helical structure by forming non native chemical bonds or bulky adducts [8]. DNA damage can occur due to two main agents viz. endogenous cellular processes and exogenous agents.

DNA DAMAGE - DiVA Portal

To explore the distribution and repair rate of TAM-DNA adducts, the level of TAM-DNA adducts in all tissues of rats and mice was monitored for 28 days and 7 days, respectively, after the termination of TAM treatment, form of covalent DNA adducts. DNA adducts are poten-tial substrates for repair enzymes or polymerases, or they can block these activities, triggering biological responses including cell death and mutation. Diverse chemical sources, structures and biological consequences are associated with DNA adduct formation. Furthermore, when considering DNA ably repaired by homologous recombinational repair.

O6-Methylguanine DNA methyltransferase (MGMT; DNA alkyltransferase) cleaves both methyl and ethyl adducts from guanine bases on the DNA structure.
