Diabète, malnutrition et retard de croissance.

We investigated the cellular mechanisms responsible for growth hormone (GH) resistance in diabetes and malnutrition in the rat. In insulin-dependent diabetes, a post-receptor defect participates in GH resistance. During fasting, there is a loss of liver GH binding sites. Dietary protein restriction causes a post-receptor defect. This defect can be attributed to the combined effects of decreased liver IGF-I mRNA content and impaired message translation.
