SLC26A4 and idiopathic pulmonary fibrosis: In addition, we found that SLC26A4 is also highly expressed in goblet cells of patients with COPD and idiopathic pulmonary fibrosis (IPF) as compared to control lungs when analyses were performed on public datasets from the Gene Expression Omnibus (GEO) database GSE136831 with scRNA-Seq of whole lung dissociates from IPF, COPD, and control lungs (Figure 6) [83].
