Transcription profiling of human normal pancreas samples, and samples from patients with chronic pancreatitis, pancreatic cancer and metastatic pancreatic cancer

ABSTRACT: This dataset presents the gene expression profiles of 36 frozen pancreas samples. RNA from 9 normal pancreas samples, 9 samples from patients with chronic pancreatitis, 9 samples from patients with pancreatic cancer and 9 samples from patients with metastatic pancreatic cancer was extracted and hybridized individually to Affymetrix HG_U95Av2 microarray chips. The data present a gene expression profile of the pancreas in normal and diseased states and has been used to identify genes which may play an important role in disease of the pancreas.

A shift of the angiogenic balance to the proangiogenic state, termed the "angiogenic switch," is a hallmark of cancer progression. Here we devise a strategy for identifying genetic participants of the angiogenic switch based on inverse regulation of genes in human endothelial cells in response to key endogenous pro- and antiangiogenic proteins. This approach reveals a global network pattern for vascular homeostasis connecting known angiogenesis-related genes with previously unknown signaling com ...[more]

Chronic pancreatitis vs pancreatic cancer LC-MS

Project description:Age-standardized incidence rates for pancreatic cancer (PC) in men have increased by 25% from 1957 to 2011 in Finland. The average age of diagnosis for PC is 69 years in Nordic males, whereas the average age of diagnosis of chronic pancreatitis (CP) is 40-50 years, but the cases overlap in age. By radiology the evaluation of a pancreatic mass, i.e. the differential diagnosis between CP and PC is often difficult. Preoperative needle biopsies are difficult to obtain and are demanding to interpret. New blood based biomarkers are needed. The accuracy of the only established biomarker for PC, CA 19-9 is rather poor in differentiating between benign and malignant mass of the pancreas. In this study, we have performed mass spectrometry HDMSE analysis of serum samples from patients with chronic pancreatitis and pancreatic cancer. We have quantified 652 proteins and performed detailed statistical analysis such as principal component analysis, orthogonal partial least square discriminant analysis and receiver operating curve analysis.

Pancreatic cancer and pancreatitis miRNA profiles

Project description:This project analyzes pancreatic tissue profiles of pancreatic cancer patients, pancreatitis patients, and controls. Since miRNAs are known to be valuable diagnostic markers, we asked whether respective patterns of pancreatic cancer patients can be detected in biopsies. The project aimed at an impoved understanding of complex profiles rather than single markers. Thus, a high-throughput technique was necessary, profiling all known miRNAs integratively. Three markers have been validated by using qPCR. n = 22 normal controls, n = 27 pancreatitis samples, and n = 136 pancreatic cancer samples have been screened for the complete miRNA repertoire. Please note that each miRNA has been measured in seven replicates and the median of the replica has been computed.

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.

Single-cell transcriptomic analysis of mouse pancreas: characteristic features of pancreatic ductal cells in chronic pancreatitis

Project description:Chronic pancreatitis (CP) is a pathogenically complex fibro-inflammatory disorder of the pancreas. Our understanding of CP pathogenesis is partly limited by the incomplete characterization of pancreatic cell types. Here, we performed single-cell RNA sequencing on 3,386 cells from the pancreas of one control mouse and mice with caerulein-induced CP. These data provides a preliminary description of the single-cell transcriptome profiles of mouse pancreata and accurately demonstrates the characteristics of pancreatic ductal cells in CP.

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).

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.
