Type 2 diabetes in humans and in obese mice is polygenic. In recent genome-wide association studies, genetic markers explaining a small portion of the genetic contribution to the disease were discovered. However, functional evidence linking these genes with the pathogenesis of diabetes is scarce. We performed RNA sequencing-based transcriptomics of islets from two obese mouse strains, a diabetes-susceptible (NZO) and a diabetes-resistant (B6-ob/ob) mouse, after a short glucose challenge and compared these results with human data. Alignment of 2,328 differentially expressed genes to 106 human diabetes candidate genes revealed an overlap of 20 genes, including TCF7L2, IGFBP2, CDKN2A, CDKN2B, GRB10, and PRC1. The data provide a functional validation of human diabetes candidate genes, including those involved in regulating islet cell recovery and proliferation, and identify additional candidates that could be involved in human beta-cell failure.
