To determine whether AURKB is upregulated during TGFα‐induced pulmonary fibrosis, Western blot analysis was performed on total lung lysates from control (CCSP/‐) and TGFα (CCSP/TGFα) mice on Dox for 6 weeks using antibodies against AURKA and AURKB. The gene discussed is TGFA; the disease is pulmonary fibrosis.
