Rotenone and 1-methyl-4-phenyl pyridinium (MPP+) are two mitochondrial neurotoxins known to produce Parkinson's disease (PD) in experimental animals. In the present study, we compared drug-induced rotational asymmetry in rats lesioned using these neurotoxins at three distinct basal ganglia sites, the striatum, substantia nigra pars compacta (SNpc) and(More)
AbstractAim:Hepatic glycogen phosphorylase (GP) and glucose-6-phosphatase (G6Pase) play an important role in the control of blood glucose homeostasis and are proposed to be potential targets for anti-diabetic drugs. Geniposide is an iridoid glucoside extracted from Gardenia jasminoides Ellis fruits and has been reported to have a hypoglycemic effect.(More)
AbstractAim:To investigate whether geniposide, an iridoid glucoside extracted from gardenia jasminoides ellis fruits, inhibits cell adhesion to human umbilical vein endothelial cells (HUVECs) induced by high glucose and its underlying mechanisms.Methods:HUVECs were isolated from human umbilical cords and cultured. The adhesion of monocytes to HUVECs was(More)
AIM Hepatic glycogen phosphorylase (GP) and glucose-6-phosphatase (G6Pase) are important in control of blood glucose homeostasis, and are considered to be potential targets for antidiabetic drugs. Astragaloside IV has been reported to have a hypoglycemic effect. However, the biochemical mechanisms by which astragaloside IV regulates hepatic(More)
Hydnocarpus wightiana is advocated in traditional Indian medicine to possess strong antidiabetic activity. In the course of identifying bioactive fractions from Indian medicinal plants we observed that acetone extract of the seed hulls of H. wightiana possess strong free radicals (DPPH and ABTS) scavenging, alpha-glucosidase and moderate(More)
OBJECTIVE To investigate the anti-HIV effects of Eucommia ulmoides Oliver, so as to provide experimental basis for searching a new efficacious drug for treatment of AIDS. METHODS Using phytochemistry to isolate compounds from Eucommia ulmoides Oliver, the inhibitory activity of Samples on the HIV gp41 six-helix bundle formation was determined by a(More)
AbstractAim:Exocytosis of endothelial Weibel-Palade bodies, which contain von Willebrand factor (VWF), P-selectin and other modulators, plays an important role in both inflammation and thrombosis. The present study investigates whether genipin, an aglycon of geniposide, inhibits endothelial exocytosis.Methods:Human umbilical vein endothelial cells (HUVECs)(More)
OBJECTIVE MicroRNAs (miRNAs) play important roles in cell proliferation, differentiation and apoptosis. 1, 3, 4-tri-O-galloyl-6-O-caffeoyl-β-D-glucopyranose (BJA32515) is a new natural ellagitannin compound extracted from Balanophora Japonica MAKINO. The effect of BJA32515 on the expression of miRNAs in cancer cells has not yet been explored. Objective The(More)
OBJECTIVE To investigate the effects of anti-oncogene p53 on the expression of secreted frizzled-related protein (sFRP), a Wnt pathway inhibitor. METHODS Human hepatocarcinoma Hep3B cells were transfected with a replication-defective adenovirus encoding p53 (Adp53), and Adp53 transgene expression was measured by fluorescence-activated cell sorting (FACS)(More)
