These uPA‐uPAR pathway components showed modest correlated expression with suPAR protein levels (uPA r = 0.40 (p = 0.02), PAI‐1 r = 0.41 (p = 0.016) MMP‐9 r = 0.37 (p = 0.04)) in cells from asthma patients not from control subject cells (Figure S1). This evidence concerns the gene SERPINE1 and asthma.
