Research resource: RNA-Seq reveals unique features of the pancreatic ?-cell transcriptome.


ABSTRACT: The pancreatic ?-cell is critical for the maintenance of glycemic control. Knowing the compendium of genes expressed in ?-cells will further our understanding of this critical cell type and may allow the identification of future antidiabetes drug targets. Here, we report the use of next-generation sequencing to obtain nearly 1 billion reads from the polyadenylated RNA of islets and purified ?-cells from mice. These data reveal novel examples of ?-cell-specific splicing events, promoter usage, and over 1000 long intergenic noncoding RNA expressed in mouse ?-cells. Many of these long intergenic noncoding RNA are ?-cell specific, and we hypothesize that this large set of novel RNA may play important roles in ?-cell function. Our data demonstrate unique features of the ?-cell transcriptome.
