Qualitative assessment of previous evidence and an updated meta-analysis confirms lack of association between the ESR1rs2234693 (PvuII) variant and coronary heart disease in men and women.
In previous association studies, the -397T/C (rs2234693) and -351A/G (rs9340799) single nucleotide polymorphisms in the estrogen receptor alpha gene (ESR1) have been implicated in the risk of coronary atherosclerosis and myocardial infarction.
Meta-analysis of the association of the rs2234693 and rs9340799 polymorphisms of estrogen receptor alpha gene with coronary heart disease risk in Chinese Han population.
The reported association has the potential to explain the risks associated with estrogen use in certain women and a recent report of association between an ESR1 haplotype comprised of c.454-397 T and c.454-351 A alleles with increased myocardial infarction and ischaemic heart disease, independent of the standard, established cardiovascular risk factors.
Effect of hormone replacement therapy on plasma lipoproteins and apolipoproteins, endothelial function and myocardial perfusion in postmenopausal women with estrogen receptor-alpha IVS1-397 C/C genotype and established coronary artery disease.
Estrogen receptor alpha (ESR1) gene variation is associated with a range of important estrogen-dependent characteristics, including responses of lipid profile and atherosclerotic severity to hormone replacement therapy, coronary heart disease risk, and migraine.
There was significant enrichment of ESR1 binding present in multiple datasets near genomic regions associated with breast cancer (7.45-fold, p = 0.001), height (2.45-fold, p = 0.002), multiple sclerosis (5.97-fold, p < 0.0002) and prostate cancer (4.47-fold, p = 0.0008), and suggestive evidence of ESR1 enrichment for regions associated with coronary artery disease, ovarian cancer, Parkinson's disease, polycystic ovarian syndrome and testicular cancer.
Collectively, these data revealed that Catalpol inhibited apoptosis and oxidative stress in glucose-deprived H9c2 cell through promoting cell mitophagy and modulating estrogen receptor, supporting the notion that Catalpol could be a novel drug candidate against myocardial ischemia for the treatment of cardiovascular diseases.
