Impact of Insulin Deprivation and Hyperglycemia on Plasma Protein Synthesis in People With Type 1 Diabetes Mellitus and Diabetes After Total Pancreatectomy
Mayo Clinic
Summary
This research is being done to better understand how insulin effects muscle, blood, and the body in people with Type 1 Diabetes.
Description
Insulin's contribution in controlling glucose homeostasis has been well appreciated but, its role in maintaining proteome homeostasis is less understood. Some animal and human studies have demonstrated that insulin signaling regulates protein synthesis and degradation as well as posttranslational modifications at the tissue level. Insulin's effect on the muscle's mitochondrial proteo-stasis has also been elucidated. Insulin deprivation increases global synthesis of splanchnic proteins based on isotope dilution studies across splanchnic bed. Most plasma proteins are derived from liver and preli…
