MetabolomicsMetabolic alterations in immune cells associate with progression to type 1 diabetes

AIMS: Previous metabolomics studies suggest that type 1 diabetes is preceded by specific metabolic disturbances. The aim of this study was to investigate whether distinct metabolic patterns occur in peripheral blood mononuclear cells (PBMCs) of children who later develop pancreat...

TranscriptomicsmicroRNA and mRNA expression profiles of human pancreatic islet-like cell clusters
Type 1 diabetes is an autoimmune destruction of pancreatic islet beta cell disease, and it is important to find new alternative source of the islet beta cells to replace the damaged cells. Human embryonic stem (hES) cells possess unlimited self-renewal and pluripotency and thus have the potential to...

TranscriptomicsRNA sequencing of pancreatic islets and islet-derived macrophages and endothelial cells modulated by vascular endothelial growth factor-A signaling
Pancreatic islet endocrine cell and endothelial cell (EC) interactions mediated by vascular endothelial growth factor-A (VEGF-A) signaling are important for islet endocrine cell differentiation and the formation of highly vascularized islets. To dissect how VEGF-A signaling modulates intra-islet vas...

ProteomicsProteomic profiling of intra-islet features reveals substructure-specific protein signatures
LCM-coupled nanoPOTS proteomics using FAIMS of intra-islet microstructures. 5 acinar samples, 5 whole islets, 5 islet interface vasculature pools, 5 islet inner microvasculature pools, 3 islets after microsvasculature removed.

MetabolomicsIAPP toxicity activates HIF1α/PFKFB3 signaling delaying β-cell loss at the expense of β-cell function
The islet in type 2 diabetes (T2D) is characterized by amyloid deposits derived from islet amyloid polypeptide (IAPP), a protein co-expressed with insulin by β-cells. In common with amyloidogenic proteins implicated in neurodegeneration, human IAPP (hIAPP) forms membrane permeant toxic oligomers imp...

TranscriptomicsComparison of endocrine enriched genes in islet beta cells versus induced beta cells
Endocrine enriched genes in adult islet beta cells were identified and compared with that of induced beta cells (with M3 transcription factors) in adult. The control sample is non-beta pancreatic cells. Gene expression profile comparison of 3 samples, 3 independent repeats for each sample indicate ...

TranscriptomicsTranscription profiling of human islet cells CD40L vs islet cells controls
Expression of CD40 in non-hematopoietic cells has been linked to inflammation. We presented evidence that CD40, a T-cell costimulatory molecule, is expressed in human β-cells and the engagement of CD40 in insulinoma cells activated the NFKB and ERK1/2 pathways. CD40 activation in human islets cell...

TranscriptomicsRNA-sequencing identifies dysregulation of the human pancreatic islet transcriptome by the saturated fatty acid palmitate
Pancreatic beta-cell dysfunction and death are central in the pathogenesis of type 2 diabetes. Saturated fatty acids cause beta-cell failure and contribute to diabetes development in genetically predisposed individuals. Here we used RNA-sequencing to map transcripts expressed in five palmitate-treat...

GenomicsDynamic epigenetic regulation by menin during pancreatic islet tumor formation
loss of Men1 in mouse pancreatic islet cells alters the epigenetic landscape of a subset of target genes. H3K4me3 ChIP-seq from either mouse pancreatic islets or mouse pancreatic islet tumors harvested at different stages.

TranscriptomicsThe human pancreatic islet transcriptome: impact of pro-inflammatory cytokines
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...
