Pim-1 is a serine/threonine kinase and involved in cell survival and proliferation. Recently, it has been shown that pim-1 signaling pathway plays an important role in cardiovascular protection and differentiation. In this study, we sought to explore the expression of pim-1 in human vascular endothelial cells (ECs) and its regulation by(More)
An elevated plasma level of 5-hydroxytryptamine (5-HT) or upregulation of 5-HT receptor signaling or both is implicated in vascular contraction and remodeling in pulmonary arterial hypertension (PAH). Recently, peroxisome proliferator-activated receptor-γ (PPARγ) agonists have been shown to ameliorate PAH. However, their effects on the 5-HT-induced(More)
Peroxisome proliferator-activated receptor-γ (PPARγ) is a member of the ligand-activated nuclear receptor family. Thiazolidinediones, such as rosiglitazone and pioglitazone, are synthetic agonists selective for PPARγ and have been used in the clinical treatment of type 2 diabetes. However, beyond the metabolic effects on glycemic control, PPARγ and its(More)
Angiogenesis, a crucial step in tumor growth and metastasis, is regulated by various pro- or anti-angiogenic factors. Recently, microRNAs have been shown to modulate angiogenic processes by modulating the expression of critical angiogenic factors. However, roles of tumor-derived microRNAs in regulating tumor vascularization remain to be elucidated. In this(More)
Thiazolidinediones (TZDs) including rosiglitazone (RSG) and pioglitazone (PIO) are synthetic agonists selective for peroxisome proliferator-activated receptor-γ (PPARγ) and have been clinically used to treat type-II diabetes as insulin sensitizers. Recent meta-analyses have shown that TZDs are associated with an increased risk for the development of heart(More)
Pulmonary arterial hypertension (PAH) is a progressive and fatal disease, which involves pulmonary vasoconstriction and cardiovas-cular remodeling. Our present study shows that treatment with rosi-glitazone, the peroxisome proliferator-activated receptor γ (PPARγ) agonist is able to attenuate 5-hydroxytryptamine (5-HT)-induced vasoconstriction of pulmonary(More)
Excessive activation of the NLRP3 inflammasome is implicated in cardiovascular diseases. Statins exert an anti-inflammatory effect independent of their cholesterol lowering effect. This study investigated the potential role of statins in the activation of the NLRP3 inflammasome in endothelial cells (ECs). Western blotting and qRT-PCR showed that(More)
