Hepatic transcriptome analysis of control and severe acute pancreatitis mice
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. Overall design: Liver mRNA profiles of 6 weeks old wild type, SAP mice were generated by sequencing in six repeat,in two mouse models.
