For example, histone deacetylase inhibitors (HDACi), trichostatin A (TSA), and LBH589 (Panobinostat, HDACi), as well as the hypomethylating agent and 5-aza-decitbine, were reported to induce PR expression in breast and endometrial cancer cells [21,23,38]. The gene discussed is PGR; the disease is endometrial cancer.
