Potier et al., Am J Physiol Endocrinol Metab 2003
(Coronary Artery Disease...) :
We examined and compared estrogen receptor ( ER ) and progesterone receptor (PR) expression and the effects of 17beta-estradiol ( E2 ) and progesterone ( P ) on collagen synthesis and matrix metalloproteinase ( MMP ) activities in the aortic arch and in cultured aortic smooth muscle cells ( ASMC ) of atherosclerosis-susceptible ( C57Bl6/J, B6 ) or -resistant ( C3H/HeJ, C3H ) mice
Hou et al., Oncogene 2004
(Breast Neoplasms...) :
Similar effects of ERbeta on MMP-9 and Ets-1 expression noted in vitro studies were also observed in the in vivo studies
