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...

ProteomicsHuman islet of Langerhans grown on nanosubstrates LC-MSMS
Intensive efforts are focused on identifying regulators of human pancreatic islet cell growth and maturation to accelerate development of therapies for diabetes. In the present study we evaluate the contribution of the physical properties of the extracellular matrix in supporting long term culture o...

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...

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...

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...

TranscriptomicsUse of the Fluidigm C1 platform for RNA sequencing of single mouse pancreatic islet cells
This study provides an assessment of the Fluidigm C1 platform for RNA sequencing of single mouse pancreatic islet cells. The system combines microfluidic technology and nanoliter-scale reactions. We sequenced 622 cells allowing identification of 341 islet cells with high-quality gene expression prof...

TranscriptomicsSingle-cell transcriptomics reveals unique features of human pancreatic islet cell subtypes
We report the single-cell RNA-seq based identification of 6 known human islet cell types (alpha cells, beta cells, delta cells, pp cells, acinar cells and duct cells) based on the expression of known marker genes. We further assess cell type specific gene expression and suggest novel marker genes fo...
