Research Abstract

Pancreatic β cell mass contributes to the development of diabetes. We show that induction of 4E-BP1 promotes β cell survival under ER stress. The Eif4ebp1 gene encoding 4E-BP1 was revealed to be a direct target of the transcription factor ATF4. We also found that hepatic activation of extracellular regulated kinase signaling induced pancreatic β cell proliferation through a neuronal-mediated relay of metabolic signals. Thus, inter-organ metabolic relay systems may serve as valuable targets in regenerative treatments for diabetes.
