Relaxin and prostaglandin E-2 regulate interleukin 11 during human endometrial stromal cell decidualization

Abstract

Decidualization of endometrial stromal cells and IL-11 signaling are essential for embryo implantation in the mouse. We investigated the effects of relaxin (RLX) and prostaglandin E(2) (PGE(2)) on IL-11 secretion by human endometrial stromal cells (HESC) and during cAMP or medroxyprogesterone acetate (P)-induced decidualization. cAMP-decidualized HESC secreted high levels of IL-11. RLX, cAMP, or PGE(2) increased IL-11 mRNA and IL-11 secretion, with maximal response to RLX and cAMP. Addition of the cAMP/protein kinase A inhibitor Rp-adenosine-3,5-cyclic-monophosphorothioate to either RLX- or PGE(2)-treated cells decreased IL-11 secretion. Indomethacin treatment decreased IL-11 secretion, whic..
