However, the authors also leveraged data from other published sources, confirming that SLC39A8 expression was decreased in AEC2s from individuals with IPF compared with healthy cells, via GEO data sets GSE135893 (11), GSE132915 (12), GSE132771 (13), and GSE128033 (14). This evidence concerns the gene SLC39A8 and idiopathic pulmonary fibrosis.
