MED31 and pulmonary fibrosis: 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).
