Abstract
The past decades have seen a dramatic improvement in our ability to phenotype and molecularly profile human tissues relevant to the etiology of type 2 diabetes with unprecedented resolution, at the genomic, epigenomic, protein, and functional levels. Here we will employ state-of-the-art technologies to determine all aspects of pancreas biology as it pertains to type 2 diabetes, profile human pancreatic islets with multiple assay modalities, and make the vast data accumulated available through the highly accessible PANC-DB. This comprehensive profiling of the natural history of Type 2 diabetes will pave the way for future discoveries of new treatment modalities for diabetes.
