To read the full abstract: Sci Rep. 2020;10(1):3078. doi: 10.1038/s41598-020-59743-4Short summary: This study describes a specific mechanism of reduced bone formation secondary to hyperglycaemia. In hyperglycaemic states, advanced glycation end products (AGEs) downregulate the highly selective magnesium transporter expression of NIPA2 in osteoblasts. This results in ma...

Brief summary: In this experimental study, genome editing and in vitro pancreatic differentiation of human pluripotent stem cells (SC) were used to generate ZNT8 loss-of-function (LOF) SC-β-cells. These cells showed accelerated functional maturation, increased insulin secretion and improved resistance to metabolic stress. Transplantation of ZnT8 LOF SC-β-cells into mice with preexisting diabetes significantly improved their glucose levels.<...
