Apr 26, 2016 by News Staff

An international team of scientists from New Zealand, Australia and the UK — including Prof. Colin Willoughby from the University of Liverpool — has identified a specific gene that plays a key role in epithelial recurrent erosion dystrophy (ERED), a genetic corneal dystrophy disorder that causes abnormality of the outer layer of the eye. The discovery solves a 20-year-old puzzle for a family in Liverpool, UK, who all developed ERED. Normal...

Postnatal maturation of pancreatic beta cells necessary for maximal glucosestimulated insulin secretion is coordinated by the estrogen-related receptor g (ERRg). ERRg drives a transcriptional program promoting mitochondrial oxidative metabolism, and its expression in iPSC-derived beta-like cells generates functional beta cells in vitro.
