Ferulic acid (FA) has been demonstrated to have a remarkable antioxidant activity, the mechanism of FA of protecting human umbilical vein endothelial cells (HUVECs) from radiation induced oxidative stress was investigated in the present study. The oxidative protection of FA was assessed by cellular glutathione (GSH) content, nicotinamide adenine(More)
To study the effect of Panax notoginseng saponins (PNS) on liver drug metabolic enzyme activity, mRNA and protein expressions in rats. Male Wistar rats were randomly divided into nine groups. After administration of the test drugs, their liver microsomes, liver total RNA and total protein were extracted to detect the regulating effect of PNS on liver drug(More)
In order to study effects of ginseng on the metabolism of drug belong to CYP3A4 substrate, screening of pregnane X receptor activation from ginsenosides was performed by reporter assay. Based on PXR-CYP3A stable translation cell lines, 13 ginsenosides were screened for pregnane X receptor activation by reporter assays, and RIF as the positive control. The(More)
Radiation induces an important inflammatory response in the irradiated organs, characterized by leukocyte infiltration and vascular changes. Since adhesion molecules play an important role in facilitating the immune response at the inflammation sites, interfering with the expression of these molecules may be an important therapeutic target of radiation(More)
In an attempt to find new types of anti-hypoxic agents from herbs, we identified 5-hydroxymethyl-2-furfural (5-HMF) as a natural agent that fulfills the criterion. 5-HMF, the final product of carbohydrate metabolism, has favorable biological effects such as anti-oxidant activity and inhibiting sickling of red blood cells. The role of 5-HMF in hypoxia,(More)
PURPOSE The objective of this study was to investigate the radioprotective effect of ferulic acid (FA) on irradiated lymphocytes and discover the possible mechanisms of protection. MATERIALS AND METHODS Lymphocytes were pretreated for 12 h with FA (0.001-0.1 μM) and then exposed to 3 Gy radiation. Cell apoptosis, intracellular reactive oxygen species(More)
OBJECTIVE To study the effects of Siwu decoction on protein expression of blood deficiency mice induced by cyclophosphamide (CIX) and discuss the possible molecular mechanism on blood enriching function of Siwu decoction. METHOD Blood deficiency mice were established by injecting ip with 250 mg x kg(-1) CTX. Proteomic technologies were applied to identify(More)
OBJECTIVE To research the effects of Siwu tang on serum protein of blood deficiency using proteomic technique and further explore its potential molecular mechanism to cure blood deficiency. METHOD The sera of normal, blood deficiency and cured group were collected. Proteomic protocol involving the high resolution two-dimensional polyacryamide gel(More)
Licorice (LE) has been commonly used in traditional Chinese medicine (TCM) for over 4000 years to reconcile various drugs and for hepatic disorders. Glycyrrhizin is the main bioactive component isolated from LE herbs. In the present study we examined the effects of glycyrrhizin on pregnane X receptor (PXR)-mediated CYP3A expression and its hepatoprotective(More)
AIM To investigate the proliferation of vascular smooth muscle cells (VSMC) affected by ginsenoside Rg1 and further explore the molecular mechanism of ginsenoside Rg1 using proteomics. METHODS The proliferation of VSMC was measured by MTS assay kit and flow cytometry. Proteomic alterations were analyzed using two-dimensional electrophoresis and peptide(More)
