Epigenetic changes marked by DNA methylation have been proposed to play a role in age-related disease. We investigated DNA methylation changes in cardiovascular atherosclerotic tissues and in-vitro vascular senescence in the promoter of estrogen receptor β gene, which has essential roles in vascular function. Coronary atherosclerotic tissues showed higher methylation levels (28.7%) than normal appearing...
Objective: Methylation of the promoter region of the estrogen receptor gene alpha (ER α) occurs as a function of age in human colon, and results in inactivation of gene transcription. In this study, we sought to determine whether such age-related methylation occurs in the cardiovascular system, and whether it is associated with atherosclerotic disease. Methods: We used Southern blot analysis to determine...
