Action of progesterone receptor modulators on uterine leiomyomas. 2008

N Ohara

Novel progesterone receptor modulators (PRMs) have recently been demonstrated to be effective in the treatment of patients with symptomatic uterine leiomyomata. PRMs are shown to reduce leiomyoma size and improve leiomyoma-associated symptoms. However, the precise mechanisms underlying the action of PRMs remain to be elucidated. My co-workers and I have investigated in vitro action of PRMs in cultured leiomyoma cells and revealed that PRMs inhibit cell proliferation and induce apoptosis of leiomyoma cells. Moreover, our recent studies show that PRMs can modulate the metabolism of extracellular matrix proteins in cultured leiomyoma cells toward the collagenolysis. The update about an action of PRMs in uterine leiomyoma cells in vitro is described in this article.

UI	MeSH Term	Description	Entries
D007889	Leiomyoma	A benign tumor derived from smooth muscle tissue, also known as a fibroid tumor. They rarely occur outside of the UTERUS and the GASTROINTESTINAL TRACT but can occur in the SKIN and SUBCUTANEOUS TISSUE, probably arising from the smooth muscle of small blood vessels in these tissues.

D009649	Norpregnadienes	Pregnadienes which have undergone ring contractions or are lacking carbon-18 or carbon-19.
D010091	Oximes	Compounds that contain the radical R2C	Aldoximes,Hydroxyimino Compounds,Ketoxime,Ketoximes,Oxime,Compounds, Hydroxyimino
D011980	Receptors, Progesterone	Specific proteins found in or on cells of progesterone target tissues that specifically combine with progesterone. The cytosol progesterone-receptor complex then associates with the nucleic acids to initiate protein synthesis. There are two kinds of progesterone receptors, A and B. Both are induced by estrogen and have short half-lives.
