Transplacental Carcinogenesis with Dibenzo[def,p]chrysene (DBC): Timing of Maternal Exposures Determines Target Tissue Response in Offspring

Creator:: Shorey, Lyndsey, Castro, David J., Baird, William, Siddens, Beth, Lohr, Christiane, Matzke, Melissa, Waters, Katrina M., Corley, Richard A., and Williams, David E.
Abstract:: Dibenzo[def,p]chrysene (DBC) is a transplacental carcinogen in mice (15 mg/kg; gestation day (GD) 17). To mimic residual exposure throughout pregnancy, dams received 4 smaller doses of DBC (3.75 mg/kg) on GD 5, 9, 13 and 17. This regimen alleviated the previously established carcinogenic responses in the thymus, lung, and liver....

Preliminary physiologically based pharmacokinetic models for benzo[a]pyrene and dibenzo[def,p]chrysene in rodents

Creator:: Crowell, Susan Ritger, Amin, Shantu G., Anderson, Kim A., Krishnegowda, Gowdahalli, Sharma, Arun K., Soelberg, Jolen J., Williams, David E., and Corley, Richard A.
Abstract:: Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous environmental contaminants generated as byproducts of natural and anthropogenic combustion processes. Despite significant public health concern, physiologically based pharmacokinetic (PBPK) modeling efforts for PAHs have so far been limited to naphthalene, plus simpler PK models for pyrene, nitropyrene, and benzo[a]pyrene (B[a]P). The dearth of...

Kim
Abstract:: An increasing number of studies suggest an important role of host immunity as a barrier to tumor formation and progression. Complex mechanisms and multiple pathways are involved in evading innate and adaptive immune responses, with a broad spectrum of chemicals displaying the potential to adversely influence immunosurveillance. The evaluation of...

Polycyclic aromatic hydrocarbons as skin carcinogens: Comparison of benzo[a]pyrene, dibenzo[def,p]chrysene and three environmental mixtures in the FVB/N mouse

Creator:: Siddens, Lisbeth K., Larkin, Andrew, Krueger, Sharon K., Bradfield, Christopher A., Waters, Katrina M., Tilton, Susan C., Pereira, Cliff B., Lohr, Christiane V., Arlt, Volker M., Phillips, David H., Williams, David E., and Baird, William M.
Abstract:: The polycyclic aromatic hydrocarbon (PAH), benzo[a]pyrene (BaP), was compared to dibenzo[def,p]chrysene (DBC) and combinations of three environmental PAH mixtures (coal tar, diesel particulate and cigarette smoke condensate) using a two stage, FVB/N mouse skin tumor model. DBC (4 nmol) was most potent, reaching 100% tumor incidence with a shorter latency...

Human in vivo Pharmacokinetics of [¹⁴C]Dibenzo[def,p]chrysene by Accelerator Mass Spectrometry Following Oral Micro-Dosing

Creator:: Madeen, Erin, Corley, Richard A., Crowell, Susan, Turteltaub, Kenneth, Ognibene, Ted, Malfatti, Mike, McQuistan, Tammie J., Garrard, Mary, Sudakin, Dan, and Williams, David E.
Abstract:: Dibenzo(def,p)chrysene (DBC), (also known as dibenzo[a,l]pyrene), is a high molecular weight polycyclic aromatic hydrocarbon (PAH) found in the environment, including food, produced by the incomplete combustion of hydrocarbons. DBC, classified by IARC as a 2A probable human carcinogen, has a relative potency factor (RPF) in animal cancer models 30-fold higher...

Abstract:: As part of the Halifax Project, this review brings attention to the potential effects of environmental chemicals on important molecular and cellular regulators of the cancer hallmark of evading growth suppression. Specifically, we review the mechanisms by which cancer cells escape the growth-inhibitory signals of p53, retinoblastoma protein, transforming growth...

Abstract:: Cell death is a process of dying within biological cells that are ceasing to function. This process is essential in regulating organism development, tissue homeostasis, and to eliminate cells in the body that are irreparably damaged. In general, dysfunction in normal cellular death is tightly linked to cancer progression. Specifically,...

Abstract:: The aim of this work is to review current knowledge relating the established cancer hallmark, sustained cell proliferation to the existence of chemicals present as low dose mixtures in the environment. Normal cell proliferation is under tight control, i.e. cells respond to a signal to proliferate, and although most cells...
