The objective of this work is to add to the body of translational data between high dose animal model research and the environmentally relevant human metabolism of the persistent pollutant dibenzo[def,p]chrysene (DBC). We furthered the knowledge of gene/exposure interactions by determining the carcinogenesis risk based on Cyp1b1 genotype following in...
Due to their unique physical, chemical, and magnetic properties, nanomaterials have great potential for industrial development. There is a pressing need to develop rapid whole animal-based testing assays to assess the potential toxicity of engineered nanomaterials. To meet this challenge the embryonic zebrafish model was employed to determine the toxicity...
microRNAs (miRNAs), ~21-24 nucleotide-long RNAs that post-transcriptionally regulate gene expression, have rapidly become one of the most extensively studied mechanisms of the past decade. Since their discovery as temporal regulators of post-embryonic development in C. elegans, miRNAs have been functionally implicated in almost every cellular process investigated to date. miRNAs...
Polychlorinated dibenzo-p-dioxins (PCDD's) and
dibenzofurans (PCDF's) are environmental pollutants associated with the production and use of a number of industrial
chemicals. In addition, PCDD's and PCDF's are produced
during low temperature combustion of wastes containing
polyvinylchloride (PVC), chlorophenols, and a number of
other chemical precursors.
A significant source of environmental...
Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous in the environment as components of fossil fuels and by-products of combustion. Defining toxicity mechanisms for this large family of multi-ring structures and substituted derivatives is a substantial challenge. Several PAHs, such as benzo(a)pyrene (BaP), are mutagenic, toxic to wildlife, and classified as probable...

A large number of river otter (Lontra canadensis) males were collected
from areas of high and low contaminant concentrations throughout western
Oregon and Washington during the fall and winter of 1994-99. Few significant
non-reproductive organ morphometric differences were found in the large series
of male otters collected, except for adrenal...

Numerous human conditions would be improved if therapies to encourage tissue regeneration were available. The goal of regenerative medicine is to encourage the body's intrinsic ability to repair and restore tissues lost by disease, injury or aging. While certain vertebrates have the inherent capacity to regenerate, mammals do not. To...
