Stomach proteins were immunoblotted for Estrogen-alpha, ER-beta, progesterone receptor-A, PR-B. ER-alpha, PR-A and PR-B were detected. PR isoforms were not regulated by hormones. E2 down-regulated ER-alpha in corpus. This suggests that E2 and P4 actions in stomach are mediated by their nuclear receptors. http://www.physorg.com/news144671228.html Medicine & Health Fri, 31 Oct 2008 11:27:08 EST news144671228 New research findings published online in The FASEB Journal provide more evidence that if we get smart about what we eat, our intelligence can improve.
