Estrogen regulates endothelial migration via plasminogen activator inhibitor (PAI-1).

Endothelial plasminogen activator inhibitor (PAI-1) controls vascular remodeling, angiogenesis and fibrinolysis. PAI-1 blood levels in women are related to estrogen. The aim of this study was to characterize the signaling pathways through which estrogen regulates PAI-1 in endothelial cells.

Dydrogesterone exerts endothelial anti-inflammatory actions decreasing expression of leukocyte adhesion molecules.

Clinical observations and basic studies show that progesterone and progestins have a variable influence on endothelial function. Dydrogesterone (DG) is a widely used progestin, but its endothelial actions have not been thoroughly assessed. In this study, we investigated the effects of DG and its metabolite 20-α-dihydro-dydrogesterone (DHD), natural progesterone as well as medroxyprogesterone acetate, on the expression of leukocyte adhesion molecules in human endothelial cells using an in vitro experimental endothelial inflammation system.

Estrogen-like effects of wine extracts on nitric oxide synthesis in human endothelial cells.

Endothelial dysfunction frequently ensues during the climacteric due to hormonal and metabolic changes. Non-pharmacological interventions such as lifestyle and dietary modifications are emerging as valuable strategies to counteract the cardiovascular consequences of ageing. A number of chemical components of wine, including alcohol and some polyphenols, are known to be active on the vessels.

Effects of red clover extracts on breast cancer cell migration and invasion.

Postmenopausal hormone therapy is associated with increased incidence of breast cancer. For this reason alternative therapeutic options to treat menopausal symptoms have been developed. Red clover extracts (RCE) are rich in isoflavones, particularly genistein and daidzein and they have been proved to be effective in reducing vasomotor symptoms in a number of studies.
