title: Cell differentiation and L-ornithine decarboxylase activity in the small intestine of rats fed low and high protein diets.
abstract: L-Ornithine decarboxylase activity is higher in enterocytes from rats fed low protein rather than high protein diets. Intestinal cell proliferation rate is 50% higher in rats fed high protein than low protein diets. This is not consistent with a direct role of ornithine decarboxylase in intestinal proliferation. It is shown that ornithine decarboxylase is preferentially associated with differentiating villus cells in intestine from rats fed low protein diets.
