Adhesion molecules have a key role in pathological inflammation. Thus, we investigated the effect of anthocyanins on the induction of intercellular adhesion molecule-1 (ICAM-1) and vascular cell adhesion molecule-1 (VCAM-1) by TNF-alpha and the possible molecular mechanisms by which anthocyanins differentially regulate ICAM-1 and VCAM-1 expression.(More)
The aim of the present study was to evaluate the protective effect of cryptotanshinone (CTS), one of active ingredients of Salvia miltiorrhiza root, on myocardial ischemia-reperfusion injury in rat due to inhibition of some inflammatory events that occur by NF-kappaB-activation during ischemia and reperfusion. Myocardial ischemia and reperfusion injury was(More)
BACKGROUND AND PURPOSE Recently, metformin, a well-known anti-diabetic drug, has been shown to possess anti-inflammatory activities. This study investigated the effect of metformin on the expression of pro-inflammatory cytokines including high mobility group box 1 (HMGB1) in lipopolysaccharide (LPS)-treated animals and cells. EXPERIMENTAL APPROACH We(More)
The role of cell adhesion molecules has been studied extensively in the process of inflammation, and these molecules are critical components of carcinogenesis and cancer metastasis. This study investigated the effect of tanshinone I derived from the traditional herbal medicine, Salvia miltiorrhiza Bunge, on the expression of intercellular adhesion(More)
Paeonol (2'-hydroxy-4'-methoxyacetophenone), the main active compound of the traditionally used Chinese herb Paeonia lactiflora Pallas, has anti-inflammatory, antioxidant and cardiovascular protective activities. We studied how the levels of intercellular adhesion molecule-1 (ICAM-1), one of the key molecules in the development of atherosclerosis, might be(More)
INTRODUCTION Hyperglycemia is a risk factor for cardiovascular complications in diabetic state. Hyperglycemia-induced oxidative stress up-regulates intracellular adhesion molecule-1 (ICAM-1) which aggravates endothelial dysfunction, although the underlying mechanisms remain unclear. We hypothesized that carbon monoxide (CO) attenuates ICAM-1 expression(More)
The aim of this study was to investigate the effects of paeoniflorin (PF) and paeonol (PN), the main active compounds of the Paeonia albiflora Pallas, on myocardial ischemia and reperfusion (I/R)-induced injury in Sprague-Dawley rats IN VIVO. Under anesthesia, the rats were subjected to 25 min of ischemia by ligation of the left anterior descending coronary(More)
The biological actions of retinoids are mediated by nuclear retinoic acid receptors (RARs) and retinoid X receptors (RXRs). We have recently reported that decreased expression of RARα and RXRα has an important role in high glucose (HG)-induced cardiomyocyte apoptosis. However, the regulatory mechanisms of HG effects on RARα and RXRα remain unclear. Using(More)
Phosphotase and tensin homolog deleted on chromosome 10 (PTEN) is a potent negative regulator of PI3K/Akt pathway. Here, we tried to elucidate the role of PTEN in the regulation of endothelial adhesion molecules, vascular cell adhesion molecule (VCAM)-1 and intracellular adhesion molecule (ICAM)-1, induced by TNF-α in human endothelial cells (ECs).(More)
The fruits of Poncirus trifoliata (L.) are widely used in Oriental medicine to treat allergic inflammation. Recently, several active compounds including hesperidin, hesperidin methyl chalone and phellopterin from P. trifoliata (Rutaceae) were isolated and characterized. The goal of this study was to investigate the differential effect of hesperidin,(More)
