Is intimal estrogen receptor ( ER ) beta , but not ERalpha expression , correlated with coronary calcification and atherosclerosis in pre- and postmenopausal women?
ERbeta is the predominant ER in human coronary arteries and correlates with coronary calcification, a marker of severe atherosclerosis. Increased ERbeta expression is linked to advanced atherosclerosis and calcification independent of age or hormone status. Future pharmacogenetic studies that target this receptor are needed to confirm causality.
LOH on 9p and 17p are highly frequent events in BE, even in the absence of dysplasia and adenocarcinoma. The presence of these abnormalities in non-neoplastic epithelium suggests they might be useful markers for risk stratification within endoscopic surveillance programs.
