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). The gene discussed is PLAU; the disease is asthma.
