Expression data from mouse lung epithelial cells during E. coli pneumonia in the presence or absence of LIF neutralization (24 h)

Leukemia inhibitory factor (LIF) is a cytoprotective cytokine that reduces lung injury during pneumonia. The purpose of this study was to determine the influence of LIF on pneumonia-induced gene changes in lung epithelium. Mice received intratracheal instillations of vehicle (PBS) or Escherichia coli (10^6 CFU). Control IgG or anti-LIF specific IgG was included in the instillate. 24 hours after the challenge, lung epithelial cells (EpCAM+/CD45-) were sorted from enzymatic lung digests and used for RNA isolation and microarray analysis. RNA from 3 separate groups of mice (3 mice per group) was analyzed: 1) 24h Vehicle/control IgG-treated; 2) 24h E. coli/control IgG-treated; and 3) 24h E. coli/anti-LIF-specific IgG.
