Inflammatory damage contributes to β cell failure in type 1 and 2 diabetes (T1D T2D, respectively). Mitochondria are damaged by inflammatory signaling cells, resulting impaired bioenergetics initiation of proapoptotic machinery. Hence, the identification protective responses inflammation could lead new therapeutic targets. Here, we report that mitophagy serves as a response stress both human rodent cells. Utilizing vivo reporters, observed diabetogenic proinflammatory cytokines induced...

Most eukaryotic mRNAs contain a 5' cap (m7GpppX) and 3' poly(A) tail to increase synergistically the translational efficiency. Recently, binding protein (PABP) cap-binding protein, eIF-4F, were found interact [Le et al. (1997) J. Biol. Chem. 272, 16247−16255; Tarun Sachs (1996) EMBO 15, 7168−7177]. These data suggest that PABP may exert its effect on efficiency either by increasing formation of initiation factor−mRNA complex or enhancing ribosome recycling. To investigate functional...

Mesenchymal stem cells (MSCs) have been described to induce angiogenesis in various tissues and used for the development of novel cell‐based therapies. Increasing evidence suggests that MSCs execute their paracrine function via secretion exosomes, especially under hypoxic conditions. However, mechanisms by which MSC‐derived exosomes secreted hypoxia enhance still remain unclear. To study exosome physiology or normoxic conditions, we isolated from bone marrow mesenchymal (BMSCs). Furthermore,...

Type 2 diabetes mellitus (T2DM) is characterized by impaired glucose-stimulated insulin secretion and increased peripheral resistance. Unremitting endoplasmic reticulum (ER) stress can lead to beta-cell apoptosis has been linked type diabetes. Although many studies have attempted link ER T2DM, the specific effects of on function remain incompletely understood. To determine interrelationship between function, here we treated insulin-secreting INS-1(832/13) cells or isolated mouse islets with...
