Upon activation by therapeutics, the nuclear xenobiotic/ constitutive active/androstane receptor (CAR) regulates various liver functions ranging from drug metabolism and excretion to energy metabolism. CAR can also be a risk factor for developing liver diseases such as hepatocellular carcinoma. Here we have characterized the conserved threonine 38 of human(More)
Transient receptor potential channels (TRPCs) are widely expressed and regulate Ca²⁺ entry in the cells that participate in the pathophysiology of airway hyperreactivity, inflammation, and remodeling. In vitro studies point to a role for TRPC1-mediated Ca²⁺ signaling in several of these cell types; however, physiological evidence is lacking. Here we(More)
BACKGROUND We previously demonstrated that cyclooxygenase (COX)-1 deficiency results in greater morbidity and inflammation, whereas COX-2 deficiency leads to reduced morbidity, inflammation and mortality in influenza infected mice. METHODOLOGY/PRINCIPAL FINDINGS We investigated the effects of COX-1 and COX-2 inhibitors in influenza A viral infection. Mice(More)
Imiquimod is a topical immune response modifier that has proved efficacious in the treatment of the superficial variant of basal cell carcinoma. The nodular variant of basal cell carcinoma has shown moderate response to imiquimod; other variants have not been tested. The mechanism of action is largely unknown; however, studies indicate the mechanism(More)
Liver tumors from a previous National Toxicology Program study were examined using global gene expression and mutation analysis to define the mechanisms of carcinogenesis in mice exposed to oxazepam. Five hepatocellular adenomas and 5 hepatocellular carcinomas from male B6C3F1 mice exposed to 5000 ppm oxazepam and 6 histologically normal liver samples from(More)
Methyl eugenol induces neuroendocrine (NE) cell hyperplasia and tumors in F344/N rat stomach. Detailed histopathological and immunohistochemical (IHC) characterization of these tumors has not been previously reported. The objective of this study was to fill that data gap. Archived slides and paraffin blocks were retrieved from the National Toxicology(More)
