Transcription profiling of human pancreas from patients with autoimmune pancreatitis and alcohol-induced chronic pancreatitis

Project description:Autoimmune pancreatitis (AIP) is a recently identified disease of the pancreas with unknown etiology and antigens. The aim of this study was to determine new target antigens and differentially regulated genes and proteins by means of transcriptomics and proteomics and to validate them in patients with autoimmune pancreatitis. Here we report a distinct downregulation at the RNA and protein level of pancreatic proteases (anionic trypsinogen, cationic trypsinogen, mesotrypsinogen, elastase IIIB) and pancreatic stone protein in autoimmune pancreatitis in comparison to alcohol-induced chronic pancreatitis.

Transcriptome profiling of the pancreas samples from animals showing autoimmune pancreatitis and chronic pancreatitis

Project description:Autoimmune pancreatitis (AIP) is a disease with unclear immunologic triggers. This study shows that the pancreatic stellate cells are involved in the regulation of the immune response and can cause autoimmunity when the NF-κB signalling in these cells is disrupted.

The heparin-binding proteome in nomal pancreas and murine experimental acute pancreatitis, C4PR_LIV

Project description:Acute pancreatitis (AP) is an acute inflammation of the pancreas, mainly caused by gallstones and alcohol, and driven by changes in communication between cells. Heparin-binding proteins (HBPs) of the plasma membrane and extracellular matrix play a central role in cell communication. Therefore, we used heparin affinity proteomics to identify the extracellular HBPs in mouse normal pancreas (NP) and in a caerulein mouse model of AP. Many new HBPs (460) were discovered more than doubling their total number to 883. A number of the new HBPs are proteins with well-characterised intracellular functions, e.g. NDUFS4, NDUFS6, but which also have a documented extracellular presence with potential ‘moonlighting’ roles. The HBPs form highly interconnected protein-protein interaction networks in both NP and AP, as well as globally. Thus, HBPs may represent the most interconnected set of extracellular proteins and so those with the greatest regulatory potential. HBPs in NP are associated with biological functions such as molecular transport, cellular movement and tissue architecture that underlie pancreatic homeostasis. However, in AP HBPs are additionally associated with processes such as acute phase response signalling, complement system and mitochondrial dysfunction. By virtue of their extracellular location and heparin binding property, HBPs are easily accessible and are potential biomarkers and drug targets in AP.

RNA-Seq of isolated pancreatic stellate cells from mice with autoimmune pancreatitis and chronic pancreatitis

Project description:Autoimmune pancreatitis (AIP) is a disease with unclear immunologic triggers. This study shows that the pancreatic stellate cells(PSCs) are involved in the regulation of the immune response and can cause autoimmunity when the NF-κB signalling in these cells is disrupted. The PSCs were isolated from animals which show autoimmune pancreatitis (NEMO knockout group) or chronic pancreatitis (NEMO wildtype group).

Characteristics of long non-coding RNAs in the pancreas of rats with acute pancreatitis

Project description:This study aimed to describe the microarray-based differential expression profile of mRNAs and lncRNAs in acute experimental pancreatitis and identify candidate biomarkers for the diagnosis, prognosis, and treatment of AP.

mRNA expression pattern of KrasG12D mice with acute pancreatitis compared with wild-type mice without acute pancreatitis

Project description:Transgenic KrasG12D mice can recapitulate pancreas intra-epithelial neoplasia (PanIN). Caerulein is a cholecystokinin analogue and induces acute pancreatitis when injected intra-abdominally. Caerulein-induced acute pancreatitis will accelerate PanIN progression in KrasG12D mice. We compared mRNA profile changes between KrasG12D mice with acute caerulein-induced pancreatitis and wild-type mice without acute pancreatitis. The experiment had two groups. Experiment group: KrasG12D mice with acute caerulein-induced pancreatitis (N=6). Three mice in experiment group received 1-week caerulein injection, and the other three mice received 2-week caerulein injection. All experiment group mice started to receive caerulein injection at 1-month of age, and were sacrificed at the last day of caerulein injection. Control group: wild-type mice without acute pancreatitis (N=6). The mice were sacrificed at 1.5-month of age. Whole pancreas tissue lysate samples were subjected to mRNA array assay.

A Novel Approach for Pancreas Transcriptomics Reveals the Cellular Landscape in Homeostasis and Acute Pancreatitis

Project description:BACKGROUND & AIMS: Acinar cells produce digestive enzymes that impede transcriptomic characterization of the exocrine pancreas. Thus, single-cell RNA-sequencing (scRNA-seq) studies of the pancreas underrepresent acinar cells relative to histological expectations, and a robust approach to capture pancreatic cell responses in disease states is needed. We sought to innovate a method that overcomes these challenges to accelerate study of the pancreas in health and disease. METHODS: We introduce FixNCut, a scRNA-seq approach where tissue is reversibly fixed with dithiobis(succinimidyl propionate) prior to dissociation and single-cell preparation. We apply FixNCut to an established mouse model of acute pancreatitis, validate findings using GeoMx whole transcriptome atlas (WTA) profiling, and integrate our data with prior studies to benchmark our method in both mouse and human pancreas datasets. RESULTS: FixNCut achieves unprecedented definition of challenging pancreatic cells including acinar and immune populations in homeostasis and acute pancreatitis, and identifies changes in all major cell types during injury and recovery. We define the acinar transcriptome during homeostasis and acinar-to-ductal metaplasia and establish a unique gene set to measure deviation from normal acinar identity. We characterize pancreatic immune cells, and analysis of T-cell subsets reveals a polarization of the homeostatic pancreas towards type-2 immunity. We report immune responses during acute pancreatitis and recovery, including early neutrophil infiltration, expansion of dendritic cell subsets, and a substantial shift in the transcriptome of macrophages due to both resident macrophage activation and monocyte infiltration. CONCLUSIONS: FixNCut preserves pancreatic transcriptomes to uncover novel cell states during homeostasis and following pancreatitis, establishing a broadly applicable approach and reference atlas for study of pancreas biology and disease.

Cerulein induced acute pancreatitis in C57Bl/6J

Project description:There still is a lack of specific, early markers for acute pancreatitis. We used the gene expression profiling Affimetrix mouse gene 1.0 ST arrays (Affymetrix , Inc. Santa Clara, CA), to cmpare the gene expression between control mice and mice with induced experimental acute pancreatitis, in order to identify new potential biomarkers of acute pancreatitis.
