Abstract

Growing and mature rats were examined for the effect of a change in dietary protein requirements on the induction of liver serine dehydratase (SDH). The rats were fed on diets varying in casein content, and the weight change and nitrogen balance was determined. SDH activity and its gene expression were induced in both growing and mature rats when their protein intake exceeded their nutritional requirements.
