Medroxyprogesterone Acetate

SKU: orb1309193

Description

Medroxyprogesterone Acetate (Farlutin) is a synthetic 17-hydroxyprogesterone-derived progestin. It functions as a long-acting contraceptive via oral or intramuscular routes and is utilized in oncology research, particularly for studying hormone-responsive breast and endometrial cancers in experimental models.

Bioactivity

• In Vivo:
  Medroxyprogesterone acetate (MPA) reduces the secretion of IL-6 and PTHrP in human breast cancer cells and downregulates their expression in KTC-2 cells in a dose-dependent manner. In M-1 cells, MPA and dexamethasone increase the promoter-driven luciferase activity of α-ENaC in a dose-dependent fashion, an effect which is not inhibited by Org31710, indicating that MPA's regulation of α-ENaC is independent of the progesterone receptor (PR). Similarly, MPA and dexamethasone upregulate the mRNA of α-ENaC and SGK1 in both M-1 and Madin-Darby canine kidney-C7 cells, whereas progesterone does not exhibit this effect. At 0.1 nM, MPA significantly enhances the in vitro production of specific immunoglobulin G antibodies, an effect that seems to involve the interaction between progesterone and the PRG receptor. MPA also inhibits the enzyme 3-hydroxysteroid dehydrogenase, which is involved in the reversible conversion between THP and DHP, thereby potentially affecting the action of DHP and THP in the brain.

• In Vitro:
  Medroxyprogesterone acetate (MPA) and progesterone significantly reduced the levels of glutamic acid decarboxylase (GAD) in the hippocampus, while markedly increasing GAD levels in the olfactory cortex. In aged ovariectomized rats, MPA impaired the retention of delayed memory in the swim arm task and exacerbated overnight forgetting in the Morris water maze.
