Hybrid insulin peptides (HIPs) result from the linkage of an insulin C-peptide fragment and another peptide via a traditional peptide bond to generate a sequence that is not encoded in the genome. Here, we sought to identify HIPs naturally present in the pancreatic islets of non-obese diabetic (NOD)...

We have used RNA-seq to identify transcripts, including splice variants, expressed in human islets of Langerhans under control condition or following exposure to the pro-inflammatory cytokines interleukin-1β (IL-1β) and interferon-γ (IFN-γ). A total of 29,776 transcripts were identified as expressed...

We performed global location analysis of Pdx1 occupancy in mouse and human islets.

Little is known about the contribution of the epigenome to the pathophysiology of type 2 diabetes (T2D). Here we have used genome-wide DNA methylation profiling to obtain the first comprehensive DNA methylation data set for human T2D pancreatic islets. Therefore, we analyzed the methylation profile ...

The β-cell plays a central role in the pathogenesis of T1D by neoantigen formation due to the generation of post-translational modifications, such as deamidation, being potential triggers for breaking immune tolerance. We report the detection by LC-MS/MS of 16 novel Gln and 27 novel Asn deamidations...

Type 2 diabetes mellitus (T2DM) is a complex disease characterized by the inability of the insulin-producing β-cells in the endocrine pancreas to overcome insulin resistance in peripheral tissues. To determine if microRNAs are involved in the pathogenesis of human T2DM, we sequenced the small RNAs o...

Close to 50 genetic loci have been associated with type 2 diabetes (T2D), but they explain only 15% of the heritability. In an attempt to identify additional T2D genes, we analyzed global gene expression in human islets from 63 donors. Islets from cadaver donors (54 non-diabetic and 9 diabetic) were...

Pancreatic islet transplantation as a cure for type 1 diabetes (T1D) cannot be scaled up due to a scarcity of human pancreas donors. In vitro expansion of beta cells from mature human pancreatic islets provides an alternative source of insulin-producing cells. The exact nature of the expanded cells ...

Partial downregulation of pancreatic endoplasmic reticulum kinase (PERK) activity recovered insulin content in human islets exposed to glucolipotoxicity (GLT), resulting in improved insulin secretion and glucose-lowering effects in a mouse model of type 2 diabetes. We conducted this study to elucida...
