    Ginsenoside Re Promotes Nerve Regeneration by Facilitating the Proliferation, Differentiation and Migration of Schwann Cells via the ERK- and JNK-Dependent Pathway in Rat Model of Sciatic Nerve Crush Injury.[Pubmed: 25776135]
    Exploring effective drugs that are capable of promoting nerve regeneration has gained much attention. Ginsenoside Re (Re) is the main ingredient of ginseng berries and roots. Research in the area has shown that Ginsenoside Re exhibits multiple pharmacological activities via different mechanisms both in vivo and in vitro. But the potential therapeutic effects of Ginsenoside Re on sciatic nerve crush injury (SNC) have been little investigated. Herein, we investigated the protect effect of Ginsenoside Re on peripheral nerve regeneration in a rat SNC model. Walking track analysis revealed that Ginsenoside Re treatment significantly promoted functional recovery of crushed sciatic nerve in rats. The expression of PCNA in rat sciatic nerve was up-regulated by Ginsenoside Re treatment, and peaked when the concentration of Ginsenoside Re was 2.0 mg/kg. Using immunofluorescent staining, we found that Ginsenoside Re greatly increased the expression of GAP-43 and S100 in injured rat sciatic nerve. Furthermore, we evaluated the effects of Ginsenoside Re on proliferation, differentiation, and migration of Schwann cells in SNC rat models. Our studies reveal that Ginsenoside Re promotes nerve regeneration is depend on ERK1/2 and JNK1/2 signaling pathway. Elevated Oct-6 expression and featured morphological changes indicated that Ginsenoside Re facilitated the differentiation of Schwann cells following SNC. Also, transwell and wound-healing assay demonstrated that the migration capabilities of Schwann cell were significantly enhanced after Ginsenoside Re treatment.

    Ginsenoside Re protects methamphetamine-induced mitochondrial burdens and proapoptosis via genetic inhibition of protein kinase C δ in human neuroblastoma dopaminergic SH-SY5Y cell lines.[Pubmed: 25523949]
    Recently, we have demonstrated that Ginsenoside Re protects methamphetamine (MA)-induced dopaminergic toxicity in mice via genetic inhibition of PKCδ and attenuation of mitochondrial stress. In addition, we have reported that induction of mitochondrial glutathione peroxidase (GPx) is also important for neuroprotection mediated by Ginsenoside Re. To extend our knowledge, we examined the effects of Ginsenoside Re against MA toxicity in vitro condition using SH-SY5Y neuroblastoma cells. Treatment with Ginsenoside Re resulted in significant attenuations against a decrease in the activity of GPx and an increase in the activity of superoxide dismutase (SOD) in the cytosolic and mitochondrial fraction. The changes in glutathione (GSH) paralleled those in GPx in the same experimental condition. Consistently, Ginsenoside Re treatment exhibited significant protections against cytosolic and mitochondrial oxidative damage (i.e. lipid peroxidation and protein oxidation), mitochondrial translocation of PKCδ, mitochondrial dysfunction (mitochondrial transmembrane potential and intra-mitochondrial Ca2+ ), apoptotic events [i.e., cytochrome c release from mitochondria, cleavage of caspase-3 and poly(ADP-ribose)polymerase-1, nuclear condensation, terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling (TUNEL)-positive apoptotic cells], and a reduction in the tyrosine hydroxylase (TH) expression and TH activity induced by MA in SH-SY5Y neuroblastoma cells. These protective effects of Ginsenoside Re were comparable to those of PKCδ antisense oligonucleotide (ASO). However, Ginsenoside Re did not significantly provide additional protective effects mediated by genetic inhibition of PKCδ. Our results suggest that PKCδ is a specific target for Ginsenoside Re-mediated protective activity against MA toxicity in SH-SY5Y neuroblastoma cells.

    Ginsenoside Re enhances small-conductance Ca(2+)-activated K(+) current in human coronary artery endothelial cells.[Pubmed: 25242515 ]
    The objectives of this study, therefore, were to test 1) whether vasorelaxing Ginsenoside Re could affect KCa current, an important regulator of NO production, in human coronary artery endothelial cells (HCAECs); and 2) whether small-conductance KCa (SKCa) channel was the channel subtype involved. Ionic currents of cultured HCAECs were studied using whole-cell patch clamp technique. Ginsenoside Re dose-dependently increased endothelial outward currents, with an EC50 of 408.90±1.59nM, and a maximum increase of 36.20±5.62% (mean±SEM; p<0.05). Apamin, an SKCa channel inhibitor, could block this effect, while La(3+), a nonselective cation channel (NSC) blocker, could not. When NSC channel, inward-rectifier K(+) channel, intermediate-, and large-conductance KCa channels were simultaneously blocked, Ginsenoside Re could still increase outward currents significantly (35.49±4.22%; p<0.05); this effect was again abolished by apamin. Repeating the experiments when Cl(-) channel was additionally blocked gave similar results. Finally, we demonstrated that Ginsenoside Re could hyperpolarize HCAECs; this effect was reversed by apamin. These data clearly indicate that Ginsenoside Re increased HCAEC outward current via SKCa channel activation, and NSC channel was not involved. This is the first report to demonstrate that Ginsenoside Re could increase SKCa channel activity in HCAECs. This can be a mechanism mediating ginseng's beneficial actions on coronary vessels.

    Establishment of an enzyme-linked immunosorbent assay and application on determination of ginsenoside Re in human saliva.[Pubmed: 25197955]
    This work describes an immunochemical approach for the quality control of Panax ginseng and a pharmacological study of Ginsenoside Re, a major bioactive constituent in P. ginseng, using an enzyme-linked immunosorbent assay. A hybridoma secreting monoclonal antibody against Ginsenoside Re was produced by fusing splenocytes immunized with a Ginsenoside Re-bovine serum albumin conjugate with the hypoxanthine-aminopterin-thymidine-sensitive mouse myeloma SP2/0 cell line. The method, at an effective measuring range of 7.8-500 ng · mL(-1) of Ginsenoside Re, successfully detected Ginsenoside Re in Chinese traditional herb prescriptions. The results demonstrate that we generated a novel and reliable assay system for measuring Ginsenoside Re in Chinese medicines more efficiently. Futhermore, we determined the Ginsenoside Re concentrations in the saliva of six healthy adults after the oral administration of a ginseng capsule to study the pharmacokinetics of Ginsenoside Re in human saliva.
