Histone deacetylase inhibition by suberoylanilide hydroxamic acid: a therapeutic approach to treat human uterine leiomyoma.

Objective To evaluate the effect of inhibition of histone deacetylases (HDACs) by suberoylanilide hydroxamic acid (SAHA) treatment of human uterine leiomyoma primary (HULP) cells in vitro on cell proliferation, cell cycle, extracellular matrix (ECM) formation, and transforming growth factor β3 (TGF-β3) signaling. Design Prospective study comparing uterine leiomyoma (UL) vs. adjacent myometrium (MM) tissue and cells with or without SAHA treatment. Setting Hospital and university laboratories. Patient(s) Women with UL without any hormone treatment. Intervention(s) Myomectomy or hysterectomy surgery in women for leiomyoma disease. Main Outcome Measure(s) HDAC activity was assessed by enzyme-li…
