Dietary Insulin Affects Leucine Aminopeptidase, Growth Hormone, Insulin-Like Growth Factor I and Insulin Receptors in the Intestinal Mucosa of Neonatal Pigs

Abstract

Collectively, dietary insulin increased mRNA levels of insulin and GH receptor, which could help explain the effect of dietary insulin on receptor-mediated postnatal development of the small intestine. Dietary insulin suppressed IGF-I receptor expression, which may be the result of negative feedback caused when insulin binds to IGF-I receptors.
