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...

MetabolomicsFFAR4-mediated IL-6 release from islet macrophages promotes insulin secretion and is compromised in type-2 diabetes

The function of islet macrophages is poorly understood. They promote glucose-stimulated insulin secretion (GSIS) in lean mice, however, the underlying mechanism has remained unclear. We show that activation of the free fatty acid receptor FFAR4 on islet macrophages leads to interleukin-6 (IL-6) r...

TranscriptomicsDetailed transcriptome atlas of the pancreatic beta cell
The aim of the present study was to explore the transcriptome of pancreatic islets and, based on this information, to prepare a comprehensive and open access inventory of insulin-producing ?-cell gene expression, the beta-Cell Gene Atlas (BCGA). INS-1 cells, primary rat beta-cells (>87% beta-cells) ...

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 ...

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...

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...

TranscriptomicsNovel Observations from Next Generation RNA Sequencing of Highly Purified Human Adult and Fetal Islet Cell Subsets
Understanding distinct gene expression patterns of normal adult and developing fetal human pancreatic a and b cells is crucial for developing stem cell therapies, islet regeneration strategies, and therapies designed to increase b cell function in patients with diabetes (type 1 or 2). Toward that en...

TranscriptomicsComprehensive mouse alpha and beta cell transcriptomes
Rodent models are widely used to study diabetes. Yet, significant gaps remain in our understanding of mouse islet physiology that reduce their accuracy as a model for human islet disease. We generated comprehensive transcriptomes of mouse beta and alpha cells using a novel bitransgenic mouse model g...

MetabolomicsOmega-3 polyunsaturated fatty acids modulate gut microbiota-derived 18β-glycyrrhetinic acid to alleviate type 1 diabetes mellitus

Background

Omega-3 polyunsaturated fatty acids (PUFAs) are known to protect against type 1 diabetes mellitus (T1DM), but how they act through the gut-islet axis is not fully understood. This study explored how Omega-3 PUFA-influenced gut microbiota and their metabolites help protect pancrea...
