The Effect of a Low Protein Diet on the Response of Rat Colonic and Hepatic Ornithine Decarboxylase Activity to Sodium Deoxycholate and Thioacetamide Treatment
Abstract:Adult male Sprague-Dawley rats fed ad libitum AIN-76A diet with 5% casein for 10 days had the same basal level of colonic ornithine decarboxylase (ODC) as rats fed 20% casein, but showed a higher level following induction of the colonic enzyme by sodium deoxycholate. Total colonic ODC activity was more responsive than holo-ODC activity to the regimen of induction, which suggested to us that functional (i.e., holoenzyme) levels of the decarboxylase may not be as sensitive to dietary modulation as total enzyme l… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
