Vitellogenesis : a biomarker for estrogenic and antiestrogenic effects of organochlorines in rainbow trout

Creator:: Donohoe, Regina M.
Abstract:: Persistent organochlorines (OCs) bioaccumulate in aquatic biota and potentially impair reproduction via endocrine disruption. The present research evaluated estrogenic effects of the OCs, chlordecone (CD) and o,p'-DDT/DDE, and the antiestrogenicity of 3,4,5,3',4',5'-hexachlorobiphenyl (345-HCB) in juvenile rainbow trout, utilizing vitellogenesis as a biomarker. Vitellogenesis, estrogen regulated hepatic production of the yolk...

Antioxidant enzyme response in rainbow trout (Oncorhynchus mykiss) after subchronic exposure to an environmentally-relevant polycyclic aromatic hydrocarbon mixture

Creator:: Norby, Tyler S.
Abstract:: Polycyclic aromatic hydrocarbons (PAHs) are significant pollutants in aquatic environments. Many are carcinogenic and lead to DNA fragmentation and adduct formation in marine and freshwater organisms. Previous research demonstrates that rainbow trout (Oncorhynchus mykiss) compensate to long-term PAH dietary exposures and reduce the DNA damage. The aim of this study...

Point and nonpoint source mercury pollution of Oregon Reservoirs

Creator:: Park, Jeong-Gue
Abstract:: Two Oregon reservoirs contaminated by different mercury sources were compared for mercury distribution in sediment and bioaccumulation by fish. The average mercury concentration in the sediment of Cottage Grove reservoir (0.67 ± 0.05 μg/g dry wt) was higher than for Dorena Reservoir (0.12 ± 0.01 μg/g dry wt). Sediment mercury...

Temperature-modulated 7,12-dimethylbenz(a)antheracene carcinogenicity in rainbow trout

Creator:: Zahr, Camille Reda
Abstract:: Temperature influences the incidence of chemically induced cancer in fish, with warmer temperatures being associated with higher cancer incidence. The mechanisms of temperature-modulated chemical carcinogenesis in fish, however, have not been described in detail. Therefore, one primary objective of this study was increased understanding of how temperature-modulated genotoxicity of 7,12-...

Alteration of cholesterol disposition by chlordecone is not explained by induction of cyp7a or cyp4a1

Creator:: Lee, JungA
Abstract:: Liver X receptor (LXR), farnesoid X receptor (FXR) and peroxisome proliferator-activated receptor (PPAR) are adopted orphan nuclear receptors that function as lipid sensors. These receptors respond to cellular lipid levels and regulate the expression of target gene. Previously, it was demonstrated that low doses of chlordecone (CD) pretreatment disturbed exogenous...

Alterations in mink reproductive physiology following exposure to coplanar and noncoplanar polychlorinated biphenyls (PCBs)

Creator:: Patnode, Kathleen A., 1959-
Abstract:: Female mink (Mustela vison) are highly sensitive to polychlorinated biphenyl (PCB)-induced reproductive impairment. The goal of this research was to develop a better understanding of the mechanism of PCB-induced effects on female mink, mink embryos, and surviving mink kits. Anestrous, juvenile female mink and pregnant, adult mink were exposed to...

Chlordecone (CD), a mixed steroid X receptor (SXR) and estrogen receptor alpha(ERα) agonist, altered hepatic cholesterol (CH) homeostasis and lipoprotein metabolism

Creator:: Lee, Junga
Abstract:: Overtly non-toxic doses of organochlorine (OC) insecticides perturb lipid homeostasis in mice and rats. To increase understanding of how chlordecone (CD), an OC insecticide, modulates cholesterol (CH) homeostasis, we determined the effect of CD pretreatment on the tissue and hepatic subcellular distribution of exogenous [¹⁴C]CH. Corn oil alone or CD...
