Abstract:
A variety of environmental, carcinogenic, and chemotherapeutic agents form bulky lesions on DNA that activate DNA damage checkpoint signaling pathways in human cells. To identify the mechanisms by which bulky DNA adducts induce damage signaling, we developed an in vitro assay using mammalian cell nuclear extract and plasmid DNA containing bulky adducts formed by N-acetoxy-2-acetylaminofluorene or benzo(a)pyrene diol epoxide. Using this cell-free system together with a variety of pharmacological, genetic, and biochemical approaches, we identified the DNA damage response kinases DNA-dependent pr

Abstract:
Humans are frequently exposed to the environmentally ubiquitous and potentially carcinigenic polycyclic aromatic hydrocarbon, benzo[a]pyrene (BP). BP is metabolized to highly reactive benzo[a]pyrene diol epoxides (BPDEs) in the cells. BPDEs react with DNA predominantly at the N2 position of guanine and form bulky adducts. The major BP adduct is (+)-trans-anti-[BP]-N2-dG (BP-N2-dG) that is carcinogenic. The bulky adduct block DNA synthesis by replicative or high-fidelity DNA polymerases. Some of the specialized lesion bypass polymerases (mostly belonging to Y-family) can replicate through this

Abstract:
Acrolein, a mutagenic aldehyde, is produced endogenously by lipid peroxidation and exogenously by combustion of organic materials, including tobacco products. Acrolein reacts with DNA bases forming exocyclic DNA adducts, such as γ-hydroxy-1,N2-propano-2′-deoxyguanosine (γ-HOPdG) and γ-hydroxy-1,N6-propano-2′-deoxyadenosine (γ-HOPdA). The bulky γ-HOPdG adduct blocks DNA synthesis by replicative polymerases but can be bypassed by translesion synthesis polymerases in the nucleus. Although acrolein-induced adducts are likely to be formed and persist in mitochondrial DNA, animal cell mitochondria l

Abstract:
DNA adducts play a central role in chemical carcinogenesis. The analysis of formation and repair of smoking-related DNA adducts remains particularly challenging as both smokers and nonsmokers exposed to smoke are repetitively under attack from complex mixtures of carcinogens such as polycyclic aromatic hydrocarbons andN-nitrosamines. The bulky DNA adducts, which usually have complex structure, are particularly important because of their biological relevance. Several known cellular DNA repair pathways have been known to operate in human cells on specific types of bulky DNA adducts, for example,

Studies showing that different types of DNA adducts are repaired in human cells at different rates suggest that DNA adduct conformation is the major determinant of the rate of nucleotide excision repair.

Abstract As the most nucleophilic site in DNA, the guanine N7 atom is a major site of adduction by a large number of alkylating mutagens and carcinogens. Aflatoxin B1, a powerful mutagen, is believed to act through its reaction with this DNA site. On the basis of the specificity of base substitutions induced by various adduct forms of aflatoxin, we have proposed that bulky guanine N7 adducts elicit base substitutions by two mechanisms. The first mechanism is similar to that observed for a number of bulky noninstructive lesions, whereas the second mechanism invokes mispairing between N7-adducte

Rifamycins are an extremely important class of antibacterial agents whose action results from the inhibition of DNA-dependent RNA synthesis. A special arrangement of unsubstituted hydroxy groups at C21 and C23, with oxygen atoms at C1 and C8 is essential for activity. Moreover, it is known that the antibacterial action of rifamycin is lost if either of the two former hydroxy groups undergo substitution and are no longer free to act in enzyme inhibition. In the present work, we describe the successful use of an Alder-Ene reaction between Rifamycin O, 1 and diethyl azodicarboxylate, yielding 2,

Abstract Abstract 1879 Poster Board I-903 DNA repair plays an important role in the protection of cells and tissues after exposure to genotoxic agents including chemotherapeutics. We have previously shown that, in peripheral blood mononuclear cells (PBMC) of multiple myeloma (MM) patients treated with melphalan, accumulation of DNA adducts in the p53 gene correlates with better therapeutic response, and that repair in different genes correlated with the gene transcriptional activity and the degree of local chromatin condensation (Dimopoulos et al, J Clin Oncol 2005;23:4381–9; Souliotis et al,

Abstract:
Histone deacetylase inhibitors (HDACi) are already approved for the therapy of leukemias. Since they are also emerging candidate compounds for the treatment of non-malignant diseases, HDACi with a wide therapeutic window and low hazard potential are desirable. Here, we investigated a panel of 12 novel hydroxamic acid- and benzamide-type HDACi employing non-malignant V79 hamster cells as toxicology guideline-conform in vitro model. HDACi causing a ≥10-fold preferential cytotoxicity in malignant neuroblastoma over non-malignant V79 cells were selected for further genotoxic hazard analysis, inclu

We have demonstrated that the noncovalent complex formed between DNA and an antitumor bifunctional intercalator, ditercalinium, is recognized in vitro as bulky covalent DNA lesions by the purified Escherichia coli UvrABC endonuclease. It was established that no covalent drug-DNA adduct was formed during the incubation of the drug with DNA or during subsequent incubation with the UvrAB proteins. The nucleoprotein-ditercalinium complexes appear different from those generated by repair of pyrimidine dimers. The UvrA protein is able to form a stable complex with ditercalinium-intercalated DNA in t

ABSTRACT We have investigated mechanisms that recruit the translesion synthesis (TLS) DNA polymerase Polκ to stalled replication forks. The DNA polymerase processivity factor PCNA is monoubiquitinated and interacts with Polκ in cells treated with the bulky adduct-forming genotoxin benzo[a]pyrene dihydrodiol epoxide (BPDE). A monoubiquitination-defective mutant form of PCNA fails to interact with Polκ. Small interfering RNA-mediated downregulation of the E3 ligase Rad18 inhibits BPDE-induced PCNA ubiquitination and association between PCNA and Polκ. Conversely, overexpressed Rad18 induces PCNA
