Ginsenoside Rp1 (G-Rp1) is a novel ginseng saponin with a chemopreventive action. In this study, we examined the anti-metastatic activities of G-Rp1 using relevant in vitro assays and in vivo metastasis models. Using a U937 cell-cell adhesion assay, we found that exogenously added G-Rp1 down-regulates beta1-integrin (CD29) activation at concentrations(More)
Ginsenoside Rp1 (G-Rp1) is a ginseng saponin derivative with chemopreventive and anti-cancer activities. In this study, we examined the regulatory activity of G-Rp1 on the production of interleukin (IL)-1beta, a pro-inflammatory cytokine managing acute or chronic inflammatory diseases such as septic shock and rheumatoid arthritis, from lipopolysaccharide(More)
MIMO-based systems have great potential to improve network capacity for wireless mesh networks (WMNs). Due to unique physical layer characteristics associated with MIMO systems, network performance is tightly coupled with mechanisms at physical layer and link layer. So far, research on MIMO-based WMNs is still in its infancy and little results are available(More)
We evaluated the chemopreventive properties of Ginsenoside Rp1 on 7,12-Dimethyl benz (a) anthracene (DMBA) skin papillomagenesis in Swiss albino mice. A significant reduction in values of tumor incidence, tumor burden, and cumulative number of papilloma was observed in mice treated orally with Ginsenoside Rp1 continuously at pre-, peri- and(More)

A line of evidence has shown that ginsenoside Rg3 (Rg3) could be one of bioactive ligands in brain Na+ channel regulations. Rg3 exists as stereoisomer of 20(R)- or 20(S)-form. Rg3 consists of three different parts; steroid- like backbone structure, carbohydrate portion, and aliphatic side chain [-CH2CH2CH=C(CH3)2], which is coupled to the carbon-20 of(More)
The objective of this study was to identify proteins modified with O-linked N-acetylglucosamine (O-GlcNAc) in pancreatic beta-cells and to understand their roles in cell death under hyperglycemic conditions. Here we report that heat shock protein 60 (HSP60) is modified with O-GlcNAc. Levels of O-GlcNAcylated HSP60 increased twofold in response to(More)
