Role of Hif1alpha in cytokine-induced macrophage gene expression

Hypoxia-inducible factor 1-alpha (HIF1a) is a basic helix-loop-helix PAS domain-containing protein, and is considered as the master transcriptional regulator of cellular response to hypoxia and inflammatory stimuli. Studies over the year have demonstrated that HIF1a play a critical role in innate immune cell response to infection and injury. Here we isolated bone marrow of 3 mice per group (Lyz2cre and Lyz2cre:HIF1aFl/Fl) and differentiated into macrophages by culturing them in M-CSF containing media. These cells were stimulated with 100ng/ml LPS, 10ng/ml IFNgamma, 10ng/ml IL4 or 10ng/ml IL10 for 18 hours. Total RNA was isolated and subjected to RNAseq analyses.
