Expression data from mouse livers expressing or lacking Cre recombinase during pneumonia

Cre-recombinase expression under control of an albumin promoter in the presence of floxed alleles is a highly effective and specific way to target gene mutations in hepatocytes. However, some concerns have been raised regarding off-target and/or toxic effects of cre itself, possibly confounding the interpretation of studies employing this approach. We have now used this tool to succesfully target gene deletions in hepatocytes during pneumonia, a condition which results in significant remodeling of the hepatic transcriptome. The goal of this study was to determine what effects, if any, cre expression alone has on hepatic gene expression during bacterial pneumonia.
