Project description:Obesity, as one of the major public health problems in the world, has attracted more and more attention. Rb1 is the most abundant active component of Panax ginseng and it has been reported to have benefit effects on obesity and diabetes. But the mechanisms of Rb1 in regulation of obesity are not very clear. In this study, by use of obese mice, we found that Rb1 not only reduced body weight but also decreased myostain (MSTN) expression，which plays a key role in the regulation of obesity. In vitro, we found that Rb1 treatment also decreased MSTN expression in differentiated C2C12 cells (Myoblast cells) and 3T3-L1 cells (adipocytes). Fndc5, as the downstream of MSTN, was increased after Rb1 treatment. Our results showed that Rb1 may ameliorate obesity through MSTN/Fndc5 signaling pathway. Our study provides important experimental evidences for the treatment of obesity by Rb1.after Rb1 treated.

Project description:ContextObesity, one of the major public health problems worldwide, has attracted increasing attention. Ginsenoside Rb1 is the most abundant active component of Panax ginseng C.A.Mey (Araliaceae) and is reported to have beneficial effects on obesity and diabetes. However, the mechanisms by which Rb1 regulates obesity remain to be explored.ObjectiveThis paper intends to further explore the mechanism of Rb1 in regulating obesity.Materials and methodsThe C57BL/6 obese mice were divided into two groups: the control (CTR) and Rb1. The CTR group [intraperitoneally (ip) administered with saline] and the Rb1 group (ip administered with Rb1, 40 mg/kg/d) were treated daily for four weeks. In vitro, Rb1 (0, 10, 20, 40 μM) was added to differentiated C2C12 cells and Rb1 (0, 20, 40 μM) was added to 3T3-L1 cells. After 24 h, total RNA and protein from C2C12 cells and 3T3-L1 cells were used to detect myostatin (MSTN) and fibronectin type III domain-containing 5 (FNDC5) expression.ResultsRb1 reduced the body weight and adipocyte size. Improved glucose tolerance and increased basic metabolic activity were also found in Rb1 treated mice. MSTN was downregulated in differentiated C2C12 cells, 3T3-L1 cells and adipose tissues upon Rb1 treatment. FNDC5 was increased after Rb1 treatment. However, MSTN overexpression attenuated Rb1-mediated decrease accumulation of lipid droplets in differentiated 3T3-L1 adipocytes.Discussion & conclusionsRb1 may ameliorate obesity in part through the MSTN/FNDC5 signalling pathway. Our results showed that Rb1 can be used as an effective drug in the treatment of human obesity.

Project description:Ginsenoside Rb1 (G-Rb1) has been reported to diminish inflammation associated with diseases. We investigated the effect of G-Rb1 on the inflammatory reactions and the odontogenic differentiation of human dental pulp cells (hDPCs). G-Rb1 affected the levels of TNF-α, IL-6, and IL-8, as these showed reduced levels with exposure to lipopolysaccharide (LPS). Additionally, less mRNA and protein expressions of vascular cell adhesion molecule-1 (VCAM-1) and intercellular adhesion molecule-1 (ICAM-1) were shown. G-Rb1 suppressed the LPS-induced increase of cell adhesion molecules and inflammatory cytokines, while also inhibiting PI3K/Akt, phosphorylation of NF-κB transcription factors, ERK and JNK of MAPK signaling in hDPCs.

Project description:BackgroundObesity, characterized by the excessive accumulation of triglycerides in adipocytes and their decreased excretion from adipocytes, is closely related to various health problems. Ginsenoside Rb1 (Rb1), the most active component of the traditional Chinese medicine ginseng, has been reported to have positive effects on lipid metabolism. The aim of the present study was to determine the protective effects of Rb1 on glycolipid metabolism under obesity conditions and its mechanisms and to reveal the signaling pathways involved.MethodsIn our study, male C57BL/6 mice with obesity induced by a high-fat diet (HFD) and mature 3 T3-L1 adipocytes were used to investigate the role of Rb1 in lipid accumulation and explore its possible molecular mechanism in vivo and in vitro, respectively.ResultsRb1 reduced the body weight, fat mass, adipocytes size and serum free fatty acid (FFA) concentration of obese mice. In differentiated 3 T3-L1 adipocytes, Rb1 reduced the accumulation of lipid droplets and stimulated output of triglycerides. Additionally, the expression of peroxisome proliferator-activated receptor gamma (PPARγ), phosphorylated PPARγ (Ser112) and aquaporin 7 (AQP7) was upregulated in adipocytes and adipose tissues upon Rb1 treatment. However, intervention of GW9662, PPARγ antagonist, attenuated Rb1-mediated effects on glycolipid metabolism and AQP7 levels.ConclusionsThese data indicated that Rb1 reduced body weight and improved glycolipid metabolism by upregulating PPARγ and AQP7 protein levels. Our study indicated a potential role for Rb1 in the prevention and treatment of obesity.

Project description:The breast cancer incidence has been increasing in China, with the earlier age of onset compared with Western countries. Traditional Chinese medicine has been provided as one of the major source of anti-cancer drugs. Ginseng is one of the most common traditional medicines in China. Ginsenosides, the saponins in the plant Panax (ginseng) are the major active components responsible for their chemopreventive effects from cancer. However, the mechanisms by which ginsenosides exert their anti-cancer effect remain elusive. By combining TMT-based quantitation with TiO2-based phosphopeptide enrichment, we performed a quantitative analysis of the changes of the phosphoproteomes in ginsenoside Rg3-treated breast cancer MDA-MB-231 cells. We were able to quantitate 5,140 phosphorylation sites on 2,041 phosphoproteins. Our data show that the phosphorylation status of 13 sites was changed in MDA-MB-231 cells upon Rg3 treatment. The perturbed phosphoproteins are CPSF7, EEF2, HIRIP3, MAGED2, MPRIP, MYCBP2, PAWR, PPP1R12A, RANBP2, SEPT9, TMPO, and UFL1. These proteins are involved in various biological processes, including protein synthesis, cell division, and inhibition of NF-κB signaling. Our study revealed that Rg3 exerts its anti-cancer effects through a combination of different signaling pathways.

Project description:The FDA approved drug Doxorubicin provokes copious irreversible cardiotoxicity and even increases the risk of heart failure. Considering the multiple and interacted molecular pathways in cancer, there is a big possibility that tumors are simultaneously sensitive to different drugs. This makes achievable to study the combinations of drug, having the virtues of less toxicity, higher efficacy and potentially antagonizing drug resistance in cancer therapy. In the present study, we addressed the synergistic effects of ginsenoside Rh2 on doxorubicin-treated breast cancer bearing mice. We showed that Rh2 significantly enhanced the anti-cancer effects of doxorubicin and greatly attenuated the cardiotoxicity. Transcriptomic changes can clearly distinguish the chemotherapeutic groups and non-treated control groups. Transcriptomic analysis domestrated that Rh2 protection involved in multiple vital pathways including cellular stress, apoptosis and inflammation.

Project description:We investigated mRNA expression levels in fibroblast-like synoviocytes (FLS) from rheumatoid arthritis (RA) patients, after no treatment, or after ginsenoside CK or dexamethasone treatment. The aim of the study was to determine the differences in the effects of ginsenoside CK and dexamethasone on mRNA levels in RA-FLS. Both ginsenoside CK and dexamethasone regulate some of the same inflammatory genes.
