Abstract
Recent research has demonstrated the immunomodulatory potential of Panax notoginseng in the treatment of chronic inflammatory diseases and cerebral hemorrhage, suggesting its significance in clinical practice. Nevertheless, the complex immune activity of various components has hindered a comprehensive understanding of the immune-regulating properties of Panax notoginseng, impeding its broader utilization. This review evaluates the effect of Panax notoginseng to various types of white blood cells, elucidates the underlying mechanisms, and compares the immunomodulatory effects of different Panax notoginseng active fractions, aiming to provide the theory basis for future immunomodulatory investigation.

Abstract
OBJECTIVES The study aimed to explore whether TP could improve memory in the aged type 2 diabetic rat model by regulating microbiota-immune-synaptic plasticity axis. METHODS The experiment was divided into two parts. Firstly, to investigate the effects of TP on the physiopathology of the aged T2DM model rats, rats were randomly divided into the Normal control group, the aged group, the Aged T2DM model group, the TP 75, 150, 300 mg/kg groups, the 150 mg/kg Piracetam group and the 3 mg/kg Rosiglitazone group. Then, to further verify whether TP improved memory in aged T2DM rat model by regulating intestinal flora, the fecal microbiota transplantation (FMT) from the rats in the 300 mg/kg TP group into the rats in the aged T2DM model group was carried out. Effects on gut microbiota, colonic integrity (epithelial tight junction proteins), and endotoxemia (serum LPS) were examined, along with synaptic structure, synaptic plasticity-related structural proteins and inflammation signaling of the hippocampus in our study. RESULTS Our results demonstrated that TP alleviated memory impairments in the aged T2DM rat model. The specific outcomes were as follows: TP 300 mg/kg corrected the gut dysbacteriosis, alleviated intestinal permeability reduction and peripheral/central inflammation, inhibited the TLR4/NF-κB signaling pathway. Meanwhile, TP improved the synaptic plasticity in the hippocampus of the aged T2DM model rats, whose expressions of SYN, PSD 95, NMDAR1 and GluR1 in hippocampus were significantly up-regulated. Surprisingly, rats of the FMT group displayed the same changes. DISCUSSION TP improves the memory in aged T2DM rat model. The mechanism may be related to the alteration of gut flora, which can inhibit hippocampal TLR4/NF-κB signaling to attenuate neuroinflammation, then improve synaptic plasticity. The study proposes that TP interventions aimed at manipulating the gut microbiota may hold great potential as an effective approach for preventing and treating this disease.

Abstract
With the acceleration of global aging and the rise in living standards, the achievement of healthy aging is becoming an imperative issue globally. Ginseng, a medicinal plant that has a long history of dietary intake and remarkable medicinal value, has become a research hotspot in the field of food and medicine. Ginsenosides, especially protopanaxadiol-type saponins and protopanaxatriol-type saponins, are among the most important active ingredients in ginseng. Ginsenosides have been found to exhibit powerful and diverse pharmacological activities, such as antiaging, antitumor, antifatigue and immunity enhancement activities. Their effects in antiaging mainly include (1) promotion of metabolism and stem cell proliferation, (2) protection of skin and nerves, (3) modulation of intestinal flora, (4) maintenance of mitochondrial function, and (5) enhancement of telomerase activity. The underlying mechanisms are primarily associated with the intervention of the signaling pathways in apoptosis, inflammation and oxidative stress. In this review, the mechanism of action of ginsenosides in antiaging as well as the potential values of developing ginsenoside-based functional foods and antiaging drugs are discussed.

Abstract
Aging is a cellular state characterized by a permanent cessation of cell division and evasion of apoptosis. DNA damage, metabolic dysfunction, telomere damage, and mitochondrial dysfunction are the main factors associated with senescence. Aging increases β-galactosidase activity, enhances cell spreading, and induces Lamin B1 loss, which further accelerate the aging process. It is associated with a variety of diseases, such as Alzheimer's disease, Parkinson's, type 2 diabetes, and chronic inflammation. Ginseng is a traditional Chinese medicine with anti-aging effects. The active components of ginseng, including saponins, polysaccharides, and active peptides, have antioxidant, anti-apoptotic, neuroprotective, and age-delaying effects. DNA damage is the main factor associated with aging, and the mechanism through which the active ingredients of ginseng reduce DNA damage and delay aging has not been comprehensively described. This review focuses on the anti-aging mechanisms of the active ingredients of ginseng. Furthermore, it broadens the scope of ideas for further research on natural products and aging.

Oxidative stress, cardiomyocytes senescence and contractile dysfunction in in vitro and in vivo experimental models of Chagas disease. Acta Trop 2023:106950. [PMID: 37211152 DOI: 10.1016/j.actatropica.2023.106950] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/15/2023] [Revised: 05/13/2023] [Accepted: 05/18/2023] [Indexed: 05/23/2023]
Abstract
AIMS The relationship between redox imbalance and cardiovascular senescence in infectious myocarditis is unknown. Thus, the aim of this study was to investigate whether cardiomyocytes parasitism, oxidative stress and contractile dysfunction can be correlated to senescence-associated β-galactosidase (SA-β-Gal) activity in Trypanosoma cruzi-infection in vitro and in vivo. METHODS Uninfected, T. cruzi-infected untreated and benznidazole (BZN)-treated H9c2 cardiomyocytes and rats were investigated. Parasitological, prooxidant, antioxidant, microstructural, and senescence-associated markers were quantified in vitro and in vivo. RESULTS T. cruzi infection triggered intense cardiomyocytes parasitism in vitro and in vivo, which was accompanied by reactive oxygen species (ROS) upregulation, lipids, proteins and DNA oxidation in cardiomyocytes and cardiac tissue. Oxidative stress was parallel to microstructural cell damage (e.g., increased cardiac toponin I levels) and contractile dysfunction in cardiomyocytes in vitro and in vivo, whose severity accompanied a premature cellular senescence-like phenotype revealed by increased senescence-associated β-galactosidase (SA-β-Gal) activity and DNA oxidation (8-OHdG). Cellular parasitism (e.g., infection rate and parasite load), myocarditis and T. cruzi-induced prooxidant responses were attenuated by early BZN administration to interrupt the progression of T. cruzi infection, protecting against SA-β-gal-based premature cellular senescence, microstructural damage and contractile deterioration in cardiomyocytes from T. cruzi-infected animals. CONCLUSION Our findings indicated that cell parasitism, redox imbalance and contractile dysfunction were correlated to SA-β-Gal-based cardiomyocytes premature senescence in acute T. cruzi infection. Therefore, in addition to controlling parasitism, inflammation and oxidative stress; inhibiting cardiomyocytes premature senescence should be further investigated as an additional target of specific Chagas disease therapeutics.

Abstract
This article aims to investigate the protection of the intestine from ionizing radiation-induced injury by using D-galactose (D-gal) to alter the gut microbiome. In addition, this observation opens up further lines of research to further increase therapeutic potentials. Male C57BL/6 mice were exposed to 7.5 Gy of total body irradiation (TBI) or 13 Gy of total abdominal irradiation (TAI) in this study. After adjustment, D-gal was intraperitoneally injected into mice at a dose of 750 mg/kg/day. Survival rates, body weights, histological experiments and the level of the inflammatory factor IL-1β were observed after TBI to investigate radiation injury in mice. Feces were collected from mice for 16S high-throughput sequencing after TAI. Furthermore, fecal microorganism transplantation (FMT) was performed to confirm the effect of D-gal on radiation injury recovery. Intraperitoneally administered D-gal significantly increased the survival of irradiated mice by altering the gut microbiota structure. Furthermore, the fecal microbiota transplanted from D-gal-treated mice protected against radiation injury and improved the survival rate of recipient mice. Taken together, D-gal accelerates gut recovery following radiation injury by promoting the growth of specific microorganisms, especially those in the class Erysipelotrichia. The study discovered that D-gal-induced changes in the microbiota protect against radiation-induced intestinal injury. Erysipelotrichia and its metabolites are a promising therapeutic option for post-radiation intestinal regeneration.

Ginseng under forest exerts stronger anti-aging effects compared to garden ginseng probably via regulating PI3K/AKT/mTOR pathway, SIRT1/NF-κB pathway and intestinal flora. PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2022; 105:154365. [PMID: 35930860 DOI: 10.1016/j.phymed.2022.154365] [Citation(s) in RCA: 19] [Impact Index Per Article: 9.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/06/2022] [Revised: 06/21/2022] [Accepted: 07/26/2022] [Indexed: 06/15/2023]
Abstract
BACKGROUND Ginseng is deemed to be an effective anti-aging therapy. Evidence for differences in representative active ingredients and anti-aging effects between garden ginseng (GG) and ginseng under forest (FG) is insufficient. PURPOSE The study was designed to systematically analyze the differences in the mechanistic protective effects of GG and FG on aging mice based on their compositional differences. METHODS The chemical ingredients in GG and FG were first determined. In vivo, D-galactose-induced aging mice were orally administered GG or FG (400 mg/kg/day) for 6 weeks. Behavioral parameters of mice were measured by the radial 8-arm maze, and the changes in body weight and organ indices were recorded. Blood, brain tissue, and feces were collected for biochemical analysis, histopathological staining, Western blotting, and 16S rDNA intestinal flora sequencing, respectively. RESULTS The absolute contents of total ginsenosides, polyphenols, crude polysaccharides, starch, and protein in GG were 0.71, 0.68, 1.15, 2.27, and 1.08 folds higher than those in FG, respectively; while FG exhibited a higher relative abundance of representative active ingredients (total ginsenosides, polyphenols, crude polysaccharides, and protein) but lower relative content of starch than GG. GG and FG improved hippocampal lesions and poor weight gain, organ indices, and behavioral indices, and prevented excessive oxidative stress and acetylcholinesterase activity in aging mice. What's more, GG and FG treatment ameliorated excessive apoptosis and inflammatory reaction in the aging brain by modulating apoptosis-related proteins, PI3K/AKT/mTOR pathway, and SIRT1/NF-κB pathway. GG and FG also restored the diversity and structure of gut microbiota, up-regulated the relative abundance of beneficial bacteria (e.g., Lactobacillus), and tended to exert key anti-aging effects via the microbiota-gut-brain axis. Notably, in vivo experiments confirmed that FG had a stronger anti-aging activity than GG. CONCLUSION FG exerts a more powerful anti-aging effect than GG by regulating oxidative stress, apoptosis, inflammation, and the microbe-gut-brain axis, possibly relying on the higher relative abundance of representative active ingredients (total ginsenosides, polyphenols, crude polysaccharides, and protein) in FG.

Abstract
Background Ginsenoside Rg1 is a major component of ginseng with antioxidative and antiaging effects, which is a traditional Chinese medicine. In this study, we investigated the potential spillover and mechanism of action of Rg1 on LiCl-driven hematopoietic stem cell aging. Results Collect the purified Sca-1+ hematopoietic cells for differentiation ability detection and biochemical and molecular labeling. The experiment found that Rg1 plays an antiaging role in reversing the SA-β-gal staining associated with LiCl-induced hematopoietic stem cell senescence, the increase in p53 and p21 proteins, and sustained DNA damage. At the same time, Rg1 protects hematopoietic cells from the reduced differentiation ability caused by LiCl. In addition, Rg1 increased the excessive inhibition of intracellular GSK-3β protein, resulting in the maintenance of β-catenin protein levels in hematopoietic cells after LiCl treatment. Then, the target gene level of β-catenin can be maintained. Conclusions Rg1 exerts the pharmacological effect of maintaining the activity of GSK-3β in Sca-1+ hematopoietic cells, enhances the antioxidant potential of cells, improves the redox homeostasis, and thus protects cells from the decline in differentiation ability caused by aging. This study provides a potential therapeutic strategy to reduce stem cell pool failure caused by chronic oxidative damage to hematopoietic stem cells.

Abstract
The aging process predisposes numerous homeostatic disorders, metabolic disorders, cardiovascular diseases, neurodegenerative diseases, and cancer. Changes in diet and lifestyle and therapeutic adjuvants are essential to minimize the effects of comorbidities associated with aging. Natural products such as Panax ginseng have been used to treat and prevent diseases related to aging. This review aims to investigate the effects of Panax ginseng in various conditions associated with aging, such as inflammation, oxidative stress, mitochondrial dysfunction, apoptosis, neurodegenerative and metabolic disorders, cardiovascular diseases, and cancer. The ginsenosides, chemical constituents found in Panax ginseng, can inhibit the effects of inflammatory cytokines, inhibit signaling pathways that induce inflammation, and inhibit cells that participate in inflammatory processes. Besides, ginsenosides are involved in neuroprotective effects on the central nervous system due to anti-apoptotic, antioxidant, and anti-inflammatory effects. The use of ginseng extract showed actions on lipid homeostasis, positively regulating high-density lipoprotein, down-regulating low-density lipoprotein and triglyceride levels, and producing beneficial effects on vascular endothelial function. The use of this plant in cancer resulted in improved quality of life and mood. It decreased symptoms of fatigue, nausea, vomiting, and dyspnea, reducing anxiety. Panax ginseng has been shown to exert potent therapeutic benefits that can act as a complementary treatment in managing patients with chronic diseases related to aging.

Activation of TLR4 induces severe acute pancreatitis-associated spleen injury via ROS-disrupted mitophagy pathway. Mol Immunol 2021; 142:63-75. [PMID: 34965485 DOI: 10.1016/j.molimm.2021.12.012] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/19/2021] [Revised: 11/04/2021] [Accepted: 12/13/2021] [Indexed: 02/06/2023]
Abstract
Severe acute pancreatitis (SAP) is complicated by systemic inflammatory response syndrome and multiple organ dysfunction, the disease will eventually result in death in almost half of the case. The spleen, as the largest immune organ adjacent to the pancreas, is prone to damage in SAP, thereby aggravating the damage of other organs and increasing mortality. However, to date, the research on the mechanism and treatment of spleen injury caused by SAP is still in its infancy. Herein, we investigated the mechanism of spleen injury, and explored the application potential of tuftsin for relieving spleen damage in SAP mice. Firstly, SAP mice model was constructed via the retrograde infusion of 3.5 % sodium taurocholate into the biliopancreatic duct. Then, we proved that the up-regulation of Toll-like receptor 4 (TLR4) in spleen would lead to the accumulation of reactive oxygen species (ROS) and mitochondrial dysfunction under SAP conditions. The splenic ROS and mitochondrial dysfunction could be improved by N-acetylcysteine (NAC) treatment or knocking out TLR4 in SAP mice. Meanwhile, we found that NAC treatment could also improve the autophagy of spleen tissue, suggesting that splenic ROS may affect impaired autophagy, causing the accumulation of damaged mitochondria, aggravating spleen damage. Furthermore, we verified the mechanism of spleen injury is caused by splenic ROS affecting PI3K/p-AKT/mTOR pathway-mediated autophagy. In addition, we detected the spleen injury caused by SAP could decrease the concentration of tuftsin in the serum of mice. Whereas, exogenous supplementation of tuftsin ameliorated the pathological damage, ROS accumulation, impaired autophagy, inflammation expression and apoptosis in damaged spleen. In summary, we verified the new mechanism of SAP-caused spleen damage that TLR4-induced ROS provoked mitophagy impairment and mitochondrial dysfunction in spleen via PI3K/p-AKT mTOR signaling, and the application potential of tuftsin in treating spleen injury, which might expand novel ideas and methods for the treatment of pancreatitis.

Abstract
Sarcopenia has high prevalence in the elderly population, but the genes and pathways related to aging in elderly patients with sarcopenia are poorly understood. Milk fat globule epidermal growth factor 8 (MFG-E8) is a peripheral membrane glycoprotein isolated from the milk fat globule membrane (MFGM). It has been found to exhibit various nutritional effects, including antibacterial, anti-cancer, anti-oxidant, anti-sarcopenia, and improving brain development and cognitive effects. This study aimed to investigate key differentially expressed genes (DEGs) and pathways associated with the progression of sarcopenia using bioinformatics analysis and in vitro myoblast experiment. The gene expression profiles of GSE8479 and GSE9676, which includes 40 young normal samples and 55 elderly samples, were downloaded from the Gene Expression Omnibus Database (GEO). Over 3253 DEGs were identified in the young and elderly samples (adjusted p value <0.05). A total of 213 co-expressed significantly DEGs were identified with Venn diagrams, including 82 up-regulated DEGs and 131 down-regulated DEGs. Based on the analysis of Gene Ontology (GO), protein-protein interaction (PPI) networks and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway, 10 hub genes screened by our study have been proved to play a role in regulating the occurrence and development of aging-related sarcopenia mainly via metabolic pathways, Huntington's disease, Parkinson's disease, oxidative phosphorylation and non-alcoholic fatty liver disease pathways. To further verify the protective effect of MFG-E8 on oxidative stress injured myoblasts, the cell cycle distribution, cell viability and reactive oxygen species (ROS) production were measured. The protein and mRNA levels of Akt, extracellular regulated protein kinases (ERK), p21Cip1, p27Kip1, cyclin D1, cyclin E1, cyclin-dependent kinase (CDK) 2 and 4 were quantified using qRT-PCR and western blot analysis. The results indicated that MFG-E8 has potential anti-sarcopenia effects by promoting ERK and Akt activation-mediated cell proliferation and cell cycle progression in myoblasts.

Abstract
As a potential antioxidant, astaxanthin (AST) exhibits anti-aging effects. However, its relationships to oxidative stress and immunity have yet to be sufficiently investigated. In this research, integrated analysis of oxidative stress and immunosenescence was performed to elucidate the efficacy and potential mechanisms of AST in d-galactose-induced aging in rats. The results showed that AST significantly decreased malonaldehyde (MDA) levels and increased antioxidase activity, in addition to demonstrating the ability to repair histopathological injuries to the liver, thereby attenuating oxidative stress. Nuclear factor erythroid 2-related factor 2 (Nrf2) expression was up-regulated by 117.95%, whereas Kelch-like ECH-associated protein-1 (Keap1) expression was simultaneously down-regulated by 51.22%. Moreover, AST significantly reduced interleukin-1β (IL-1β) and interleukin-6 (IL-6) levels, as well as expression of nuclear factor-kappa B (NF-κB) (p65) and i-kappa-B-alpha (IκBα) proteins. Findings of repair of immune organs, as well as elevated levels of interleukin-2 (IL-2), immunoglobulin M (IgM) and immunoglobulin G (IgG), suggest a novel mechanism by which AST could regulate cellular immunity and humoral immunity to attenuate immunosenescence. The anti-aging effects of AST were shown to be due in part to the Nrf2/Keap1 and NF-κB pathways, and AST treatment ameliorated oxidative stress and immune impairment overall.

Tea polyphenols ameliorates memory decline in aging model rats by inhibiting brain TLR4/NF-κB inflammatory signaling pathway caused by intestinal flora dysbiosis. Exp Gerontol 2021; 153:111476. [PMID: 34265410 DOI: 10.1016/j.exger.2021.111476] [Citation(s) in RCA: 16] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2021] [Revised: 07/07/2021] [Accepted: 07/07/2021] [Indexed: 12/17/2022]
Abstract
AIMS Tea is a rich source of pharmacologically active molecules that has been suggested to provide a variety of health benefits. However, its mechanism of action in aging-related intestinal flora dysbiosis mediated neuroinflammation is still unclear. This study aimed to explore whether tea polyphenols (TP) can improve memory by regulating intestinal flora mediated neuroinflammation in aging model rats. METHODS Ovariectomy (OVX) combined with D-galactose injection was used to establish aging rats related to menopause. The rats were divided into Sham control group, Aging model group, TP 75 mg/kg, 150 mg/kg, 300 mg/kg groups and VE group. After 12 weeks of intervention, the shuttle box test and Y maze test were used to check the memory of rats. The composition of intestinal flora was assessed by 16S rRNA sequencing technology. HE staining and ELISA were used to detect intestinal epithelial morphology and permeability, respectively. TLR4/NF-κB inflammation pathway related indicators were investigated by western blot, and the microglia activation in rat hippocampal tissue was checked by immunofluorescence. RESULTS In the shuttle box test and the Y maze test, compared with the Sham control group, the memory of Aging model rats was significantly declined. It was observed that the intestinal flora of Aging model rats was dysbiosis, the permeability of the intestinal epithelium was increased. Further experimental results showed that the expression of TLR4/NF-κB inflammatory pathway related proteins in the hippocampus were increased, and the excessive activation of microglia was observed. The beneficial effects of TP intervention have been found to prevent memory decline and significantly improve brain inflammation induced by intestinal flora dysbiosis, and TP 300 mg/kg showed a more obvious advantage than TP 75 mg/kg. TP 300 mg/kg can significantly improve the behavior of rats, improve the composition and diversity of the intestinal flora, and the shape and function of the intestinal epithelium. By reversing the increased expression levels of TLR4, IRAK, p-IκBα and nuclear NF-κB p65 proteins in the hippocampus of Aging model rats, the activation of microglia in the CA1, CA3 and Dentate gyrus (DG) sub-regions of the hippocampus can be inhibited. CONCLUSION TP inhibits the brain TLR4/NF-κB inflammatory signal pathway caused by the dysbiosis of intestinal flora, which may be one of the mechanisms to improve the memory decline in aging model rats.

Abstract
25-Hydroxylprotopanaxadiol-3β, 12β, 20-triol (25-OH-PPD or AD-2) belongs to dammarane ginsenoside, and is commonly obtained from the acidic hydrolysate of total ginsensides of Panax ginseng. This study investigated the potential mechanism of AD-2 toward improving thioacetamide (TAA)-induced hepatic fibrosis in mice. Mice were divided into seven groups: control group, TAA model group, TAA + AD-2 (5, 10, and 20 mg/kg) groups, TAA + silymarin (100 mg/kg) group, and TAA + Fu Fang Biejia (FFBj; 300 mg/kg) group. All mice were treated to intraperitoneal TAA injection to establish a hepatic fibrosis model, and drugs were administered orally. The mechanism and related pathways underlying the AD-2-mediated action against hepatic fibrosis were explored by Western blotting and immunohistochemical staining. After AD-2 treatment, the expression levels of Lipin-1, SREBP1, and F4/80 significantly decreased, meanwhile the protein expressions levels of IL1β, IL1R1, IL18, Bax, Bid, Bcl-2, and cFlips also decreased. Furthermore, AD-2 inhibited RAF and MEK pathways. The results demonstrate that AD-2 can alleviate hepatic fibrosis. The mechanism is likely related to the regulation of lipid accumulation, inflammatory response, apoptosis pathway, and Raf-MEK signaling pathways, which provide a basis for clinical research for the treatment of hepatic fibrosis. PRACTICAL APPLICATION: Ginsenoside is one of the main active ingredients of ginseng, and can alleviate the symptoms of various diseases, for example, hepatic fibrosis. This paper mainly used Western blotting to explore its possible mechanism of action. The goal was to provide a reference for the development of traditional Chinese medicines for hepatic fibrosis.

Abstract
AIMS Non-alcoholic fatty liver disease (NAFLD) is a common chronic liver disease and lacks for safe and effective drug to therapy completely. Ginsenoside-Rg1 is one of the main components of ginseng and has been proved to counteract a variety of diseases. However, there is currently a lack of sufficient evidence to support the efficacy of ginsenoside-Rg1 in the treatment of NAFLD. Our aim was to investigate whether Ginsenoside-Rg1 is a potential drug for NAFLD. MAIN METHODS NAFLD model in rats was established by giving a high-fat diet (HFD), ginsenoside-Rg1 was intragastrically administered 100 mg/kg/d for 8 weeks in NAFLD rat. Serum biochemical indices were measured. Liver tissues were stained with hematoxylin and eosin (HE) and oil red O. Total RNA was extracted from liver and was used for high throughput sequencing to identify the changes of transcriptome. The relevant hub genes were verified by quantitative real-time PCR and western blot. KEY FINDINGS Serum biochemical analysis indicated that ginsenoside-Rg1 improved liver function. Additionally, the staining of HE and oil red O indicated ginsenoside-Rg1 could remit pathology process of NAFLD. The transcriptome changes also support this result and reveals Atf3 and Acox2 were key genes. SIGNIFICANCE Taken together, these results suggest that the efficiency of ginsenoside-Rg1 against NAFLD and confirmed that ginsenoside-Rg1 is a potential effective drug in treatment of NAFLD.

Abstract
Panax ginseng (Meyer) and Panax notoginseng (Burkill), belonging to the family Araliaceae, are used worldwide as medicinal and functional herbs. Numerous publications over the past decades have revealed that both P. notoginseng and P. ginseng contain important bioactive ingredients such as ginsenosides and exert multiple pharmacological effects on nervous system and immune diseases. However, based on traditional Chinese medicine (TCM) theory, their applications clearly differ as ginseng reinforces vital energy and notoginseng promotes blood circulation. In this article, we review the similarities and differences between ginseng and notoginseng in terms of their chemical composition and pharmacological effects. Their chemical comparisons indicate that ginseng contains more polysaccharides and amino acids, while notoginseng has more saponins, volatile oil, and polyacetylenes. Regarding pharmacological effects, ginseng exhibits better protective effects on cardiovascular disease, nerve disease, cancer, and diabetes mellitus, whereas notoginseng displays a superior protective effect on cerebrovascular disease. The evidence presented in this review facilitates further research and clinical applications of these two herbs, and exploration of the relationship between the chemical components and disease efficacy may be the critical next step.

Abstract
Oxidative stress is considered as a major factor in aging and exacerbates aging process through a variety of molecular mechanisms. D-galactose, a normal reducing sugar with high dose can cause the accumulation of reactive oxygen species (ROS) or stimulate free radical production indirectly by the formation of advanced glycation end products in tissues, finally resulting in oxidative stress. 20(R)-ginsenoside Rg3 (20(R)-Rg3), a major and representative component isolated from red ginseng (Panax ginseng C.A Meyer), has been shown to observably have an anti-oxidative effect. We thereby investigated the beneficial effects of 20(R)-Rg3 on D-galactose-induced oxidative stress injury and its underlying mechanisms. Our results showed that continuous injection of D-galactose with 800[Formula: see text]mg/kg/day for 8 weeks increased the levels of alanine aminotransferase (ALT) and blood urea nitrogen (BUN). However, such increases were attenuated by the treatment of 20(R)-Rg3 for 4 weeks. Meanwhile, 20(R)-Rg3 markedly inhibited D-galactose-caused oxidative stress in liver and kidney. The anti-oxidants, including catalase (CAT) and superoxide dismutase (SOD), were elevated in the mice from 20(R)-Rg3-treated group compared with that from D-galactose group. In contrast, a significant decrease in levels of cytochrome P450 E1 (CYP2E1) and the lipid peroxidation product malondialdehyde (MDA) and 4-hydroxynonenal (4-HNE) were observed in the 20(R)-Rg3-treated group. These effects were associated with a significant increase of AGEs. More importantly, 20(R)-Rg3 effectively attenuated D-galactose induced apoptosis in liver and kidney via restoring the upstream PI3K/AKT signaling pathway. Taken together, our study suggests that 20(R)-Rg3 may be a novel and promising anti-oxidative therapeutic agent to prevent aging-related injuries in liver and kidney.

Abstract
We aimed to study the effects of an ethyl acetate fraction of Physalis alkekengi (PAE) on d-galactose (d-gal)-induced senescence and the underlying mechanism. Firstly, analysis of the phytochemical composition revealed total flavonoids, total phenolics, total saponins, rutin, and luteolin contents of 71.72 ± 2.99 mg rutin equivalents/g, 40.19 ± 0.47 mg gallic acid equivalents/g, 128.13 ± 1.04 mg oleanolic acid equivalents/g, 1.67 ± 0.07 mg/g and 1.61 ± 0.01 mg/g, respectively. The mice were treated with d-gal for six weeks, and from the fifth week, the mice were administered with PAE by gavage once a day for five weeks. We found significant d-gal-induced ageing-related changes, such as learning and memory impairment in novel object recognition and Y-maze, fatigue in weight-loaded forced swimming, reduced thymus coefficient, and histopathological injury of the liver, spleen, and hippocampus. The PAE effectively protected from such changes. Further evaluation showed that PAE decreased the senescence-associated β-galactosidase of the liver, spleen, and hippocampus, as well as the oxidative stress of the liver, plasma, and brain. The abundance of flavonoids, phenols, and saponins in PAE may have contributed to the above results. Overall, this study showed the potential application of PAE for the prevention or treatment of ageing-associated disorders.

Tropisetron protects against brain aging via attenuating oxidative stress, apoptosis and inflammation: The role of SIRT1 signaling. Life Sci 2020; 248:117452. [PMID: 32088214 DOI: 10.1016/j.lfs.2020.117452] [Citation(s) in RCA: 19] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2019] [Revised: 02/09/2020] [Accepted: 02/19/2020] [Indexed: 12/20/2022]
Abstract
AIMS The aim of this study was to elucidate the signaling pathway involved in the anti-aging effect of tropisetron and to clarify whether it affects mitochondrial oxidative stress, apoptosis and inflammation in the aging mouse brain by upregulating Sirtuin 1 or silent information regulator 1 (SIRT1). MATERIALS AND METHODS Aging was induced by d-galactose (DG) at the dose of 200 mg/kg body weight/day subcutaneously injected to male mice for six weeks. Tropisetron was simultaneously administered intraperitoneally once a day at three various doses (1, 3 and 5 mg/kg body weight). Oxidative stress and mitochondrial dysfunction markers were evaluated. Nitric oxide (NO) and pro-inflammatory cytokines levels including tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) were studied. Besides, the expressions of apoptosis-associated genes (Bax and Bcl-2) and the aging-related gene (SIRT1) were determined by the real time polymerase chain reaction (RT-PCR). In addition, histopathological alterations were assessed. KEY FINDINGS Tropisetron reversed the induction of oxidative damage, mitochondrial dysfunction and overproduction of inflammatory mediators induced by DG in the brain tissue. In addition, tropisetron suppressed DG-induced apoptosis and found to significantly elevate SIRT1 gene expression. Besides, tropisetron could markedly alleviate DG-induced abnormal changes in the brain morphology. SIGNIFICANCE Tropisetron exhibited anti-aging effects in the context of DG-induced senescence in mouse brain through various pathways. Our results suggest that tropisetron may attenuate DG-induced brain aging via SIRT1 signaling activation.

Regulatory Effect of Anwulignan on the Immune Function Through Its Antioxidation and Anti-Apoptosis in D-Galactose-Induced Aging Mice. Clin Interv Aging 2020; 15:97-110. [PMID: 32099340 PMCID: PMC6996228 DOI: 10.2147/cia.s237601] [Citation(s) in RCA: 13] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2019] [Accepted: 01/01/2020] [Indexed: 12/21/2022] Open
Abstract
BACKGROUND Aging is a spontaneous and inevitable phenomenon of biology, which can lead to the gradual deterioration of tissues and organs. One of the age-related deterioration processes is immunosenescence, which leads to changes in the function of immune systems, including immune cells and associated cytokines. A proper modulation of immune responses can improve the age-related immunosenescence process and then reach healthy aging. Schisandra sphenanthera, a traditional Chinese medicine, has been used as both a medicine and a nutritional supplement for thousands of years. Anwulignan, a monomer compound of Schisandra sphenanthera lignans, has been reported to possess an immunomodulatory effect. Therefore, this study was designed to further explore whether Anwulignan could also modulate the immune functions in aging model mice and the underlying mechanism. METHODS D-galactose (D-gal) is often used as an inducer of immunosenescence in animals. In this study, a mice model was created by subcutaneous D-gal (220 mg kg-1) for successive 42 days. Then, the blood and spleen tissue samples were taken for the analysis and observation of cytokine levels, immunoglobulin levels, leukocyte numbers, and the phagocytic activity of macrophages, as well as the histological changes, the proliferation ability of lymphocytes, and the biochemical parameters in the spleen tissue. RESULTS Anwulignan significantly increased the serum levels of IL-2, IL-4, IFN-γ, lgG, lgM, and lgA, decreased the content of TNF-α and IL-6 in the aging mice, and increased the blood leukocyte number, the phagocytic activity, the lymphocyte proliferation, and the spleen index in vitro. Anwulignan also significantly increased the activities of SOD and GSH-Px, decreased the contents of MDA and 8-OHdG in the spleen tissue, up-regulated the expressions of Nrf2, HO-1, and Bcl2, down-regulated the expressions of Keap1, Caspase-3, and Bax in the spleen cells, and reduced the apoptosis of spleen lymphocytes. CONCLUSION Anwulignan can restore the immune function that is declined in D-gal-induced aging mice partly related to its antioxidant capacity by activating the Nrf2/ARE pathway and downstream enzymes, as well as its anti-apoptotic effect by regulating Caspase-3 and the ratio of Bcl2 to Bax in the spleen.

Abstract
Recently, breakthroughs have been made in the use of mesenchymal stem cells (MSCs) to treat various diseases. Several stem cell types have been authorized as drugs by the European Medicines Agency and the U.S. Food and Drug Administration. The Chinese official document “Notification of the management of stem cell clinical research (trial)” was also published in August 2015. Currently, China has approved 106 official stem cell clinical research filing agencies and 62 clinical research projects, which are mostly focused on MSC therapy. Hence, the optimization and development of stem cell drugs is imperative. During this process, maximizing MSC expansion, minimizing cell loss during MSC transplantation, improving the homing rate, precisely regulating the differentiation of MSCs, and reducing MSC senescence and apoptosis are major issues in MSC preclinical research. Similar to artemisinin extracted from the stems and leaves of Artemisia annua, ginsenoside Rg1 (Rg1) is purified from the root or stem of ginseng. In the human body, Rg1 regulates organ function, which is inseparable from its regulation of adult stem cells. Rg1 treatment may effectively regulate the proliferation, differentiation, senescence, and apoptosis of MSCs in different microenvironments in vitro or in vivo. In this review, we discuss recent advances in understanding the effect of Rg1 on MSCs and describe the issues that must be addressed and prospects regarding Rg1 regulation of MSCs in preclinical or clinical studies.

Abstract
Oxidative stress contributes to chronic inflammatory processes implicated in aging, referred to as “inflamm-aging.” In this study, the potential anti-inflammatory and anti-aging effects of a pigment–protein complex (PPC) from Chlorella pyrenoidosa were investigated using lipopolysaccharide (LPS)-stimulated RAW 264.7 macrophages and D-galactose (D-gal)-induced aging in a murine model. Results indicated that PPC inhibits the production of the inflammatory cytokines TNF-α and IL-6, and the inflammatory mediator nitric oxide (NO) in LPS-stimulated RAW 264.7 cells. It also protected mice from D-gal induced informatory aging by increasing the activity of the antioxidant enzyme, such as superoxide dismutase (SOD), inhibiting D-gal-induced NF-κB upregulation, and increasing PPARs expression in the brain and gut. The findings indicated that PPC has favorable anti-inflammatory and anti-aging properties, and could be useful in the treatment of acute inflammation and senescence diseases.

Abstract
Fluoride is capable of inducing immunotoxicity, but its molecular mechanisms remain elusive. This study aimed to explore the roles of Protein kinase receptor-like ER kinase (PERK) and inositol requiring enzyme 1 (IRE1) signaling pathways in excessive fluoride-induced immunotoxicity, focusing on the regulatory roles of these two pathways in cell division and apoptosis. Firstly, we assessed the changes in cell division and apoptosis in rats exposed to 0, 50, or 100 mg/L fluoride, and detected the expression of PERK and IRE1 signaling-related proteins in spleen. Additionally, to validate the role of these two pathways, we evaluated the changes in cell division and apoptosis of primary lymphocytes from rat's spleen to 4 mM fluoride after knockdown of PERK and IRE1 in vitro. In vivo results confirmed that fluoride inhibited cell division, promoted the apoptosis and resulted in histological and ultrastructural abnormalities of rat spleen. In addition, fluoride induced activation of the PERK and IRE1 signalings and the associated apoptosis. Moreover, the in vitro results further verified the findings in vivo that fluoride activated these two signalings in B lymphocytes. Importantly, after knockdown of PERK and IRE1 in lymphocytes, the cell division ability was restored, and apoptosis decreased in fluoride-treated lymphocytes; the results correlated well with the expression of PERK and IRE1 signaling-related proteins, thus confirming the pivotal role of these pathways in immunosuppression by excessive fluoride. This study indicates that the mechanisms underlying the deleterious effects of fluoride on immune system are related to activation of the PERK and IRE1 signaling pathways.

Abstract
Ginsenoside Rg1 is the active ingredient of Chinese herbal medicine ginseng and sanqi, which has remarkable effects on anti-inflammation and anti-diabetes. In this study, we explored the molecular mechanism of ginsenoside Rg1 against diabetes in rat subjected to insulin resistance induced by high-fat and high-sugar (HFHS). Biochemical analysis revealed that ginsenoside Rg1 significantly decreased the serum levels of alanine transaminase, aspartate transaminase, alkaline phosphatase, total cholesterol, triglyceride, low-density lipoprotein and increased the serum levels of high-density lipoprotein, which indicated ginsenoside Rg1 improved the extent of hepatic steatosis. Furthermore, ginsenoside Rg1 suppressed the expression of IL-1β, IL-6,TNF-α,NF-κB and G6Pase, however, p-Akt was up-regulated. These results suggested that ginsenosideRg1 improved insulin resistance through suppressing inflammatory response and glucose output, which may be a potential therapeutic strategy in protecting hepatic steatosis.
