AURKB and idiopathic pulmonary fibrosis: Functional enrichment analysis of these negatively correlated gene sets (i.e., genes upregulated in IPF lungs but downregulated in AURKB‐specific siRNA‐treated lung fibroblasts and vice versa) using the ToppFun application of the ToppGene Suite (Chen et al, 2009) identified several major fibroblast‐specific biological processes.
