Because these compounds can act at different levels of the hypothalamus-pituitary-gonadal (HPG) axis, their effects can lead to a mixture of responses difficult to characterize. In this work, we exposed ovarian tissue of fathead minnows to the steroidogenesis inhibitor ketoconazole in order to determine its in vitro effects.</p> <p><a href="http://science-nature.marc8.com/perturbation-gene-expression-and-steroidogenesis-vitr">read more</a></p> http://science-nature.marc8.com/perturbation-gene-expression-and-steroidogenesis-vitr#comments chemicals in the environment endocrine function gene expression profile hormone synthesis steroidogenesis http://science-nature.marc8.com/crss/node/11928 Wed, 19 Nov 2008 15:43:58 -0600 admin 11928 at http://science-nature.marc8.com http://science-nature.marc8.com/mapping-prostate-cancer-genes-opens-door-new-treatment <p>Genetic changes during the initiation and progression of prostate cancer have eluded scientists to date. Now for the first time researchers have identified a specific gene expression profile of prostate cancer stem cells, with important implications for future treatments.</p> <p><a href="http://science-nature.marc8.com/mapping-prostate-cancer-genes-opens-door-new-treatment">read more</a></p> http://science-nature.marc8.com/mapping-prostate-cancer-genes-opens-door-new-treatment#comments Top stories cancer genes gene expression profile prostate cancer cells specific gene expression stem cells http://science-nature.marc8.com/crss/node/4775 Tue, 20 May 2008 14:15:10 -0500 admin 4775 at http://science-nature.marc8.com
