An aryl hydrocarbon receptor agonist amplifies the mitogenic actions of estradiol in granulosa cells: evidence of involvement of the cognate receptors
(Society for the Study of Reproduction, 2006-02)
The aryl hydrocarbon receptor (AHR) is a ligand-activated transcription factor that, besides mediating toxic responses, may have a central role in ovarian physiology. Studying the actions of AHR ligands on granulosa cells ...
Short communication: Acute but transient increase in serum insulin reduces messenger RNA expression of hepatic enzymes associated with progesterone catabolism in dairy cows
(2013-02-01)
The objective of this experiment was to evaluate the effects of glucose infusion on serum concentrations of glucose, insulin, and progesterone (P4), as well as mRNA expression of hepatic CYP2C19 and CYP3A4 in nonlactating, ...

Hepatic enzyme induction and mutagenicity of airborne particulate matter from Santiago, Chile in the nourished and malnourished rat
(1997)
1. Respirable, airborne particles in the ambient air in downtown Santiago, Chile, have
been characterized for the seasonal variation in total polycyclic aromatic hydrocarbon
content, 13 of which have been identi® ed ...
Induction of rat hepatic p4501a1 by organic extracts from airborne particulate matter in Santiago, Chile
(Informa Healthcare, 1995)
1. Organic extracts from particulate matter collected in downtown Santiago, Chile, in 1990 were administered to female Wistar rats. 2. Extracts shifted the maximal absorption wavelength P450 spectra of the reduced-CO complex ...
CYP1A1 *2B and *4 polymorphisms are associated with lung cancer susceptibility in Mexican patients
(2008)
Background: CYP1A1 is a gene involved in the high aryl hydrocarbon hydroxylase -inducible phenotype, which is a genetically-determined variation among individuals that has been associated with lung cancer risk. More ...
