Pancreatic β-cell mRNA modification as a marker for type 2 diabetes

Diabetes mellitus invariably involves impaired regulation of insulin secretion from pancreatic β cells, as a result of unfavourable environmental influences in combination with aberrant expression of risk genes at either the transcriptional or the translational level. A recent report in Nature Metabolism explores a novel role of mRNA methylation in β-cell function and suggests that its downregulation causes type 2 diabetes.
