Elevated cANGPTL4 protein in the bronchoalveolar lavage fluid of patients with pneumonia. Shown are graphs depicting the relative expression of the C-terminal isoform of ANGPTL4 protein (cANGPTL4) in (A) BALF samples (control, n = 16; ARDS, n = 7) and (B) serum samples (control, n = 8; pneumonia, n = 17) from control healthy volunteers and patients with lung disease. n.s., no statistical significance. Representative images of Western blots are shown for BALF and serum samples.
