The impact of a bulky DNA lesion on the structure and dynamics of a nucleosome core particle (NCP) containing a lesion derived from the unusually potent tumorigen dibenzo[a,l]pyrene that resists nucleotide excision repair (NER) in free DNA was investigated using
Chemical research in toxicology, 22(7), 1264-1276 (2009-05-20)
Assessment of human cancer risk from animal carcinogen studies is severely limited by inadequate experimental data at environmentally relevant exposures and by procedures requiring modeled extrapolations many orders of magnitude below observable data. We used rainbow trout, an animal model

Dibenzo[def,p]chrysene (DBC) is a potent environmental carcinogen in rodents, fish, and human cells examined in culture. There are numerous similarities between the patterns of cytochrome P-450 (P450) activation of DBC and its covalent binding to DNA and proteins with another
The carcinogenic potential of dibenzo[a,l]pyrene (DBP) has been well characterized in numerous animal models. We have previously documented that a single dose of 15 mg/Kg DBP to pregnant mice late in gestation (GD 17) produces an aggressive T-cell lymphoma as
International journal of cancer, 133(6), 1300-1309 (2013-03-14)
We previously reported that dibenzo[a,l]pyrene (DB[a,l]P), the most potent known environmental carcinogen among polycyclic aromatic hydrocarbons (PAH) congeners, is carcinogenic in the oral tissues of mice. We have now developed a new mouse model which employs the oral application of
This application note describes the fast and efficient separation of the EU’s list of 15 + 1 polynuclear aromatic hydrocarbons (PAHs) using Ascentis® Express PAH HPLC column.
