Background: Polycyclic aromatic hydrocarbons (PAHs) are carcinogenic environmental pollutants generated during incomplete combustion. After exposure and during metabolism, PAHs can form reactive epoxides that can covalently bind to DNA.

Site-specific DNA substrates for human excision repair: comparison between deoxyribose and base adducts [PDF]
Background: The genetic integrity of living organisms is maintained by a complex network of DNA repair pathways. Nucleotide excision repair (NER) is a versatile process that excises bulky base modifications from DNA.

DNA damage by lipid peroxidation products: implications in cancer, inflammation and autoimmunity
Oxidative stress and lipid peroxidation (LPO) induced by inflammation, excess metal storage and excess caloric intake cause generalized DNA damage, producing genotoxic and mutagenic effects.

BackgroundThe incidence rate of missed abortion is increasing year by year, but the etiology has not been fully elucidated. Adverse pregnancy history and exposure to polycyclic aromatic hydrocarbons (PAHs) may increase the risk of missed abortion ...

Cyclization of Short DNA Fragments [PDF]
From the per unit length free energy for DNA under tension, we have calculated an effective contour length dependent persistence length for short DNA. This effective persistence length results from the enhanced fluctuations in short DNA. It decreases for shorter DNA, making shorter DNA more flexible.

ERCC1 expression and RAD51B activity correlate with cell cycle response to platinum drug treatment not DNA repair [PDF]
Background: The H69CIS200 and H69OX400 cell lines are novel models of low-level platinum-drug resistance. Resistance was not associated with increased cellular glutathione or decreased accumulation of platinum, rather the resistant cell lines have a cell

Defects Can Increase the Melting Temperature of DNA-Nanoparticle Assemblies [PDF]
DNA-gold nanoparticle assemblies have shown promise as an alternative technology to DNA microarrays for DNA detection and RNA profiling. Understanding the effect of DNA sequences on the melting temperature of the system is central to developing reliable detection technology.

Estrogens as endogenous genotoxic agents--DNA adducts and mutations.
Estrogens induce tumors in laboratory animals and have been associated with breast and uterine cancers in humans. In relation to the role of estrogens in the induction of cancer, we examine formation of DNA adducts by reactive electrophilic estrogen ...

Controlling platinum, ruthenium, and osmium reactivity for anticancer drug design [PDF]
The main task of the medicinal chemist is to design molecules that interact specifically with derailed or degenerating processes in a diseased organism, translating the available knowledge of pathobiochemical and physiological data into chemically ...
