Studies indicate that adenomyosis involves dysregulation of multiple signaling pathways, including VEGF, Wnt, PI3K, MAPK, NF-κB, cGAS-STING, TGF-β, Hedgehog, and Hippo pathways, which regulate processes such as estrogen and progesterone imbalance, angiogenesis, proliferation and invasion, and the processes of inflammation and fibrosis. This evidence concerns the gene VEGFA and adenomyosis.
