中文摘要
胰腺β细胞团参与糖尿病的发生发展。我们发现,4E-BP1的诱导促进了β细胞在内质网应激下的存活。编码4E-BP1的Eif4ebp1基因被发现是转录因子ATF4的直接靶标。我们还发现,肝脏激活细胞外调节的激酶信号通过神经元介导的代谢信号转导诱导胰腺β细胞的增殖。因此,器官间代谢传递系统可能成为糖尿病再生治疗的有价值的靶点。
英文摘要
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.
