TRIB3 and idiopathic pulmonary fibrosis: To verify expression of TRIB3, we initially evaluated the expression of TRIB3 in healthy and IPF lungs to properly describe human disease-relevant alterations from the Gene Expression Omnibus (GEO) RNA-seq dataset (GSE32537) and found the TRIB3 expression was significantly down-regulated in IPF patients in comparison to normal donors (Figure 1A).
