Hepatic transcriptome analysis of control, acute pancreatitis and severe acute pancreatitis mice

Project description:Purpose: The purpose of this study was to compare the hepatic transcriptome in the control group, acute pancreatitis, and severe acute pancreatitis, in order to identify metabolic gene changes during pancreatitis. Methods: 6-week Balb/c mice were subjected to AP (caerulein), SAP (caerulein and LPS) and control (saline), and mice liver tissues were harvested at 24 hours for RNA preparation (n=8 each group). Results: Among 11952 mapped genes, 8977 differentially expressed genes were identified by RNA-seq, including 351 genes induced in AP compare to Control and 5249 genes down regulated in SAP compare to AP. The genes up regulated were mainly related to fatty acid oxidation and ketone body synthesis especially Cpt2 and Acadvl, while genes that down regulated were associated with energy metabolism and inflammation. The overlap of two gene sets were 96 genes that involved in fatty acid metabolism. Conclusions: Our study revealed that in AP, genes associated with ketone body synthesis are upregulated in liver, in SAP, fatty acid oxidation related genes are downregulated in liver. Our data revealed the crosstalk between pancreas and liver, illustrated the difference of metabolism in AP and SAP.

Hepatic transcriptome analysis of control and severe acute pancreatitis mice

Project description:Purpose: The purpose of this study was to compare the hepatic transcriptome in the control group and severe acute pancreatitis, in order to identify metabolic gene changes during pancreatitis. Methods: 6-week Balb/c mice were subjected to control (Saline*12) and SAP (caerulein *12), and mice liver tissues were harvested at 24 hours for RNA preparation (n=6 each group). Results: Among 18257 mapped genes, 3639 differentially expressed genes were identified by RNA-seq, including 1714 genes induced in SAP compare to Control and 1892 genes down regulated in SAP compare to Control. The genes up regulated were mainly related to immune response and ER stress, while genes that down regulated were associated with fatty acids oxidation and oxidative phosphorylation. Conclusions: Our study revealed that in SAP, genes associated with immune response are upregulated in liver, fatty acid oxidation related genes are downregulated in liver. Our data revealed the crosstalk between pancreas and liver, illustrated the change of liver metabolism in SAP.

Gene expression in lung tissue, blood and spleen of mice with severe acute pancreatitis

Project description:Severe acute pancreatitis (SAP) is a critical disease, often complicated with multiple organ dysfunction, which seriously endangeres the life safety of patients. Previous studies have shown that cGAS-STING signaling pathway is significantly activated in mice with severe acute pancreatitis. In this study, we studied the gene expression in different tissues of normal mice and SAP mice to understand the differentially expressed genes and find the downstream genes of cGAS-STING signaling pathway.

CircRNA expression profiles of pancreatic tissues from severe acute pancreatitis mice

Project description:Severe acute pancreatitis (SAP) is the most serious type of pancreatitis with high morbidity and mortality. The underlying mechanism behind SAP pathogenesis is complex and remains elusive. In the present study, next-generation RNA sequencing was utilized to identify circRNA transcripts in the pancreatic tissues from three SAP mice and three matched normal tissues. Our results discovered that 56 circRNAs were differently expressed in SAP compared with normal control. Our findings may provide novel insights for pathophysiological mechanism of SAP and offer novel targets for SAP.

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.

Gene Expression Profiling of Acute Pancreatitis

Project description:Peripheral blood was collected from 87 patients with acute pancreatitis (AP) of varying severity (Mild=57, Moderately-Severe=20, Severe=10) within 24 hours of presentation to the hospital and from 32 healthy controls. RNA-Seq was performed to identify changes in expression in severe AP cf. mild, moderately-severe, and healthy controls.
