NUCLEOLIN and pulmonary sarcoidosis: Dunn's Multiple Comparison Test of five investigated groups including all recruited patients regardless of smoking status showed significantly decreased relative expressions of AUF1 (p<0.001), HuR (p<0.001), TIA (p<0.001), TIAR (p<0.05) and NCL (p<0.001) and RECK (p<0.001) in BA cells from the patients with pulmonary sarcoidosis compared to those in healthy controls (Fig 1 and S3 Table).
