From: TRAIL signals through the ubiquitin ligase MID1 to promote pulmonary fibrosis
Serum from IPF patients had elevated levels of TRAIL (a) and lung biopsies elevated MID1 (b) protein, which corresponded with a trend towards decreased activity of PP2A (c) when compared to those from control subjects. The percentage predicted diffusing lung capacity for carbon monoxide (DLco) did not have a strong inverse association with serum TRAIL (d) but was inversely associated with MID1 protein (e) and correlated with the levels of PP2A activity (f) in lung biopsies from IPF patients. n = 8, * p < 0.05
