生物活性

製品説明 Medroxyprogesterone (MP) is a synthetic pregnane steroid and a derivative of progesterone. It is a potent progesterone receptor agonist.
in vitro Medroxyprogesterone acetate (MPA, 10 nM) treatment for 48 h induces proliferation of the cells (1.6-fold induction). MPA induces cyclin D1 expression (3.3-fold induction). MPA increases both the protein level (2.2-fold induction) and promoter activity (2.7-fold induction) of cyclin D1 in MCF-7 cells transfected with PRB but not with PRA. Although MPA transcriptionally activates cyclin D1 expression, cyclin D1 promoter does not have progesterone-responsive element-related sequence. MPA induces the transient phosphorylation of Akt (2.7-fold induction at 5 min) and also phosphorylation of inhibitor of NFkappaBalpha (IkappaBalpha) (2.3-fold induction)[1]. MPA activates glucocorticoid receptors, which could mimic part of the anti-atherosclerotic effects of glucocorticoids, and has, on the other hand, also anti-androgenic activity, which might diminish protective oestrogen effects[2].
in vivo Long-term treatment with MPA and MPA + E2 increases arterial thrombosis despite inhibitory effects of MPA on atherosclerosis in ApoE-deficient mice. Increased thrombin formation, reduced smooth muscle content and remodelling of non-collagenous plaque matrix may be involved in the pro-thrombotic effects. Thus, MPA exhibits differential effects on arterial thrombosis and on atherosclerosis. In monkeys, MPA interferes with anti-atherosclerotic oestrogen effects whereas progesterone does not[2].

実験の流れ The cells are plated at a density of 10 or 40 × 104 cells/well in 12-well plates and allowed to attach overnight. The cells are then growth arrested by incubation in phenol red-free DMEM with 10% charcoal-stripped serum for 24 h followed by treatment with vehicle or MPA by exchanging the culture medium containing these agents with fresh medium every 24 h for 4 d. A Neubauer chamber is used to count cells, and trypan blue experiments are carried out in quadruplicate.
