As a result, we found a common gene, PTX3, on both lists of dysregulated genes in IPF fibroblasts and altered genes in curcumin-treated IPF fibroblasts, which was upregulated in IPF fibroblasts compared to normal human lung fibroblasts (fold change = 2.19) and downregulated by curcumin (fold change = −5.26) (Figure 6a and Table 2). This evidence concerns the gene PTX3 and idiopathic pulmonary fibrosis.
