Berberine inhibits the proliferation of human uterine leiomyoma cells

BBR selectively inhibits cellular proliferation and blocks E2- and P4-induced cell proliferation in UtLM but not in normal UtSMC cells. In addition, BBR did not demonstrate cytotoxicity effects in normal human UtSMCs. Our results suggest BBR could be a potential therapeutic agent for the treatment of uterine leiomyoma.
