Inosine monophosphate and inosine differentially regulate endotoxemia and bacterial sepsis
Inosine monophosphate (IMP) plays a central role in intracellular purine metabolism. How IMP regulates inflammation induced by bacterial products or bacteria is unknown. In this study, we demonstrate that IMP fundamentally alters gene expression in the liver.To assess how IMP affects inflammatory cell activation in vivo, we subjected liver, the organ containing the highest numbers of macrophages in the body, to RNAseq analyses. High quality RNA was isolated from the livers of 3 vehicle- and 3 IMP-treated endotoxemic mice and submitted for RNAseq analysis. Our analysis identified 105 genes that were differentially expressed, determined by adjusted p values (42 downregulated, 63 upregulated; padj = 0.05). Overall design: RNAseq analyses in the liver tissue of vehicle- and IMP-treated endotoxemic mice
