The aromatic amine carcinogen 2-aminofluorene (AF) forms covalent adducts with DNA, predominantly with guanine at the C8 position. Such lesions are bypassed by Y-family polymerases such as Dpo4 via error-free and error-prone mechanisms. We show that Dpo4 catalyzes elongation from

Mounting evidence has shown that a novel subset of mesenchymal stem cells (MSCs) derived from human gingiva referred to as gingival mesenchymal stem cells (GMSCs) displays a greater immunotherapeutic potential and regenerative repair expression than MSCs obtained from other tissues.

Fluorescence spectroscopy was used to study carcinogen-induced conformational heterogeneity in DNA duplexes. The fluorophore 2-aminopurine (AP) was incorporated adjacent (5') to the lesion (G*) in eight different DNA duplexes [d(5'-CTTCT PG* NCCTC-3'):d(5'-GAGGN XTAGAAG-3'), G* = FAF adduct, P = AP
In this paper, the results on horseradish peroxidase (HRP)-catalyzed oxidative polymerization of amine-functionalized fluorene monomer, 2-amino fluorene (AF), are reported. The resulting polymer exhibits an exciting molecular structure and spectral properties. FT-IR and NMR studies show that the two fluorene
2-Acetylaminofluorene and 2-aminofluorene are among the most intensively studied of all chemical mutagens and carcinogens. Fundamental research findings concerning the metabolism of 2-acetylaminofluorene to electrophilic derivatives, the interaction of these derivatives with DNA, and the carcinogenic and mutagenic responses that
