PARK7 and cancer: We show that lung DJ-1 expression is decreased in 6 patients (4 male and 2 female; mean age 64.5 ± 3.1 years) with thromboembolic pulmonary hypertension with a mean ± SEM pulmonary artery systolic pressure of 70 ± 4 mmHg compared to 6 cancer patients (4 male and 2 female; mean ± SEM age 59.8 ± 4.4 years) with a pulmonary artery systolic pressure <25 mmHg (Figure 3A).
