Objectives:
Both oral estrogen-based hormone-replacement therapy and contraceptives increase the risk of venous thromboembolism. Several circulating factors involved in coagulation/fibrinolysis are expressed mainly in the liver whilst some are expressed in extrahepatic tissues, including bone marrow. The aim of this study was to identify estrogen-responsive target genes involved in the pathogenesis of estrogen-induced venous thromboembolism.
Methods:
Ovariectomized mice were treated with 17beta-estradiol and possible effects on the expression of genes related to coagulation/fibrinolysis were investigated using DNA microarray analyses.
Results:
None of the selected genes was regulated by 17beta-estradiol in the liver. Interestingly, 17beta-estradiol increased mRNA levels of coagulation factor V in the bone marrow/bone. Furthermore, this stimulatory effect of 17beta-estradiol on coagulation factor V expression can be mediated via both estrogen receptor-alpha and -beta.
Conclusions:
The expression of bone marrow-derived, but not liver-derived, coagulation factor V is increased by estrogen treatment in mice. The pathophysiological importance of this finding for estrogen-induced venous thromboembolism remains to be determined.
