CAB39L and idiopathic pulmonary fibrosis: We also assessed the expression of CAB39L and SNAI2 (encoding Snail2) in alveolar septae from control and IPF lungs using the same dataset (GSE169500) and found that the levels of CAB39L were significantly inversely correlated with SNAI2 (Snail2) (Fig. 4D; Pearson r = −0.65; n = 20; P = 0.002).
