C-reactive protein stimulates RAGE expression in human coronary artery endothelial cells in vitro via ROS generation and ERK/NF-κB activation.

Aim: The receptor for advanced glycation end-products (RAGE) plays an important role in development of atherosclerosis, and C-reactive protein (CRP) has been found to stimulate its expression in endothelial cells. In this study we investigated how CRP regulated the expression of RAGE in human coronary artery endothelial cells (HCAECs).

Methods: HCAECs were treated in vitro with CRP (50 μg/mL) in combination with a variety of inhibitors.

MicroRNA-26 was decreased in rat cardiac hypertrophy model and may be a promising therapeutic target.

MicroRNA (miR)-26 was found to be downregulated in cardiac diseases. In this study, the critical role of miR-26 in myocardial hypertrophy in both in vivo and in vitro was investigated. Sixteen male Wistar rats that underwent sham or transverse abdominal aortic constriction (TAAC) surgery were divided into control or TAAC group.

Inhibition of platelet activation and aggregation by furostanol saponins isolated from the bulbs of Allium macrostemon Bunge.

Three new furostanol saponins (FSs) were recently isolated from the dried bulbs of Allium macrostemon and were shown to have antiplatelet effects. This study investigated the inhibitory capabilities of these compounds on adenosine diphosphate (ADP)-induced human platelet activation. FS-1, when compared with the other 2, had a potent inhibitory effect on ADP-induced platelet aggregation and on the expression of P-selectin and integrin β-3.
