In studies of adenomyosis, low expression of histone deacetylase 3 (HDAC3) has been negatively correlated with the degree of fibrosis, and reduced HDAC3 expression disrupts the NF-κB pathway, impairing the resolution of inflammation and endometrium repair and ultimately exacerbating the disease [59]. The gene discussed is HDAC3; the disease is adenomyosis.
