In a more advanced stage of endometrosis, in category IIB vs I, DEGs were annotated to the pulmonary fibrosis idiopathic signaling pathway (e.g. ACTA2, AREG, ADAMTS1, WNT4, WNT11), growth of connective tissue (e.g. AGER, TIMP1) and cell proliferation of fibroblasts (e.g. AGER, FADD, FTH1, MED31, NUPR1, PDGFD, SERPINE1, TGFB1I1). This evidence concerns the gene TGFB1I1 and pulmonary fibrosis.
