BACKGROUND Estrogen receptor α (ERα) has been shown to protect against atherosclerosis. Methylation of the ERα gene can reduce ERα expression leading to a higher risk for cardiovascular disease. Recently, microRNAs have been found to regulate DNA methyltransferases (DNMTs) and thus control methylation status in several genes. We first searched for microRNAs(More)
AIMS Proliferation and migration of vascular smooth muscle cells (VSMCs) can cause atherosclerosis and neointimal formation. MicroRNAs have been shown to regulate cell proliferation and phenotype transformation. We discovered abundant expression of microRNA-195 in VSMCs and conducted a series of studies to identify its function in the cardiovascular system.(More)
AIM OF THE STUDY San-huang-xie-xin-tang (SHXXT) is a traditional Chinese medicine and it has been shown to have an anti-inflammatory effect. Since inflammation is one of the major mechanisms of atherosclerosis, we aimed to investigate anti-atherosclerotic effect of SHXXT in human aortic smooth muscle cells (HASMCs). MATERIALS AND METHODS Human aortic(More)
Transformation of macrophages to foam cells contributes to atherosclerosis. Here, we report that let-7g reduces macrophage transformation and alleviates foam cell apoptosis by suppressing both canonical and non-canonical NF-κB pathways. In the canonical pathway, let-7g inhibits phosphorylation of IKKβ and IκB, down-regulates SREBF2 and miR-33a, and(More)
