mRNA expression of ACE2 and selected interacting factors in lung tissues from IPF patients. mRNA expression of ACE2 (a), TMPRSS2 (b), TIMP3 (c), TGFB1 (d), CTGF (e). VEGFA (f) and FN1 (g) in lung tissues from IPF patients (n = 13) and lung healthy control (n = 11) were extracted from an existing microarray dataset (GSE2052). *P < 0.05 compared to lung healthy controls
