Aryl Hydrocarbon Receptors in Indole Derivative Treated Mice: Neuropharmacological Perspectives

Gonadal aryl hydrocarbon hydroxylase in rats and mice.

Rat and mouse gonadal aryl hydrocarbon hydroxylase (AHH) activity was measured and characterized in control and 3-methylcholanthrene (MC)-treated animals. The ovarian AHH activity increased 2to 3-fold in SpragueDawley, Lewis, and Brown-Norway rats following MC treatment. The same treatment decreased the testicular AHH activity in Sprague-Dawley rats. The induction of AHH activity after MC admin...

The aryl hydrocarbon receptor inhibits prostate carcinogenesis in TRAMP mice.

The aryl hydrocarbon receptor (AhR) is a transcription factor that mediates the inhibitory effects of 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) on prostate growth and also modulates normal prostate development. This is evidenced by AhR null mice (Ahr-/-) having smaller dorsolateral and anterior prostates, even though all prostate lobes remain histologically normal. To test the hypothesis that ...

The aryl hydrocarbon receptor: studies using the AHR-null mice.

The aryl hydrocarbon receptor (AHR) is believed to mediate the toxic effects of 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD), polychlorinated biphenyls, and polycyclic aromatic hydrocarbons. AHR is a member of the Per, ARNT, Sim/basic-helix-loop-helix superfamily of ligand-activated transcription factors that also harbors the transcription factors involved in the hypoxia response, development of ...

Neuropharmacological Effect of the Rhizome of Drynaria quercifolia in Mice

The neuropharmacological effect of petroleum ether and ethyl acetate soluble fractions of ethanol extract of the rhizome of Drynaria quercifolia J. Smith were studied in mice by intraperitoneal administration. The tests used were determination of effect on duration of diazepam-induced sleep, determination of effect on nikethamide-induced toxicity, light-dark test and force swimming test. The du...
