| In Vitro | In vitro activity: Medroxyprogesterone acetate (MPA) inhibits the enzyme 3-hydroxyste-roid dehydrogenase, involved in the reversible conversion between 5alpha-dihydroprogesterone (DHP) and 3alpha, 5alpha-tetrahydroprogesterone (THP), and therefore may affect the local actions of DHP and THP in the brain. Medroxyprogesterone acetate (MPA) reduces secretion of IL-6 and PTHrP from human breast cancer cells. MPA dose-dependently decreases the secretion and mRNA expression of IL-6 and PTHrP in the KTC-2 cells. Medroxyprogesterone acetate (MPA) and dexamethasone dose dependently increases alpha-ENaC promoter-driven luciferase activity in M-1 cells, which is not inhibited by Org31710, indicating that Medroxyprogesterone acetate regulates alpha-ENaC in a PR-independent manner. Medroxyprogesterone acetate and dexamethasone, but not progesterone, dose dependently increases alpha-ENaC and sgk1 mRNA in M-1 and in Madin-Darby canine kidney-C7 cells, both collecting duct cell lines. Medroxyprogesterone acetate (MPA) (0.1 nM) significantly enhances the in vitro production of specific immunoglobulin G (IgG) antibodies, an effect that appears to involve the interaction of the progestin with PRG receptors. |

| In Vivo | Medroxyprogesterone acetate (MPA) impairs delayed memory retention on the water radial-arm maze (WRAM), and exacerbates overnight forgetting on the Morris maze (MM) in aged ovariectomized (OVX) rats. Medroxyprogesterone acetate (MPA) significantly and progesterone marginally decreases GAD levels in the hippocampus, and both MPA and progesterone significantly increases GAD levels in the entorhinal cortex. |
