Abstract
Post-traumatic stress disorder (PTSD) is a serious mental disorder that can develop after exposure to extreme stress. Korean red ginseng, whose major active component is ginsenoside Rg3 (Rg3), is a widely used traditional antioxidant that has anti-inflammatory, anti-apoptotic and anxiolytics effects. This study investigated whether the administration of Rg3 ameliorated the memory deficit induced by a single prolonged stress (SPS) in rats. Male rats were dosed with Rg3 (25 or 50 mg/kg) once daily for 14 days after exposure to SPS. Rg3 administration improved fear memory and spatial memory might be involved in modulating the dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis and monoamine imbalance in the medial prefrontal cortex and hippocampus. It also increased the reduction in the brain-derived neurotrophic factor (BDNF) and tropomyosin-related kinase B (TrkB) mRNAs expression, and the ratio of p-Akt/Akt in the hippocampus. Thus, Rg3 exerted memory-improving actions might be involved in regulating HPA axis and activating BDNF-TrkB pathway. Our findings suggest that Rg3 could be useful for preventing traumatic stress, such as PTSD.

Abstract
Background To prove the internal connection, we deciphered the effect of cinnamaldehyde on kidney senescence through establishing animal and cell models. Methods In vivo, a rat senescence model was constructed using D-galactose (D-gal), and the modeled rats were further treated with cinnamaldehyde. In vitro, rat renal tubular epithelial cells (NRK-52E) were transfected with miR-155 mimic or inhibitor and then treated with cinnamaldehyde, D-gal or PI3K inhibitor (LY294002). The serum levels of blood urea nitrogen (BUN) and serum creatinine (Scr) of the rats were measured by an automatic biochemical analyzer. Pathological changes of kidney were determined by hematoxylin-eosin staining. The senescence and viability of NRK-52E cells were assessed by SA-β-gal staining and CCK-8 assay, respectively. The levels of miR-155, p-PI3K/PI3K, p-Akt/Akt, LC3B (LC3-II and LC3-I) and Beclin1 were detected by qRT-PCR, immunohistochemistry, or western blot. Results D-gal elevated the levels of BUN, Scr and miR-155 in the kidney, induced the renal pathological damage, inhibited the cell viability, increased the numbers of SA-β-gal-, LC3B- and Beclin1-positive cells and upregulated the levels of LC3-II/LC3-I and Beclin1 both in the kidney and cells. Cinnamaldehyde reversed D-gal-induced effects on the kidney and cells, and moreover, the cinnamaldehyde-induced anti-D-gal effects on cells could be suppressed by miR-155 mimic but promoted by miR-155 inhibitor. LY294002 potentiated D-gal-induced effects, and reversed cinnamaldehyde- and miR-155 inhibitor-caused impacts on the PI3K/Akt pathway and LC3-II/LC3-I level in D-gal-induced cells. Conclusion Cinnamaldehyde attenuates kidney senescence and injury through PI3K/Akt pathway-mediated autophagy via downregulating miR-155.

Abstract
Background Post-traumatic stress disorder (PTSD) is a psychiatric disease that develops following exposure to a traumatic event and is a stress-associated mental disorder characterized by an imbalance of neuroinflammation. Korean Red Ginseng (KRG) is the herbal supplement that is known to be involved in a variety of pharmacological activities. We aimed to investigate the effects of KRG on neuroinflammation as a potential mechanism involved in single prolonged stress (SPS) that negatively influences memory formation and consolidation and leads to cognitive and spatial impairment by regulating BDNF signaling, synaptic proteins, and the activation of NF-kB. Methods We analyzed the cognitive and spatial memory, and inflammatory cytokine levels during the SPS procedure. SPS model rats were injected intraperitoneally with 20, 50, or 100 mg/kg/day KRG for 14 days. Results KRG administration significantly attenuated the cognitive and spatial memory deficits, as well as the inflammatory reaction in the hippocampus associated with activation of NF-κB in the hippocampus induced by SPS. Moreover, the effects of KRG were equivalent to those exerted by paroxetine. In addition, KRG improved the expression of BDNF mRNA and the synaptic protein PSD-95 in the hippocampus. Taken together, these findings demonstrate that KRG exerts memory-improving actions by regulating anti-inflammatory activities and the NF-κB and neurotrophic pathway. Conclusion Our findings suggest that KRG is a potential functional ingredient for protecting against memory deficits in mental diseases, such as PTSD.

Abstract
Epinephrine induced MI with renal complication through Nrf2/NF-κB imbalance and PKC/AT1R. Ginseng abolished ECG changes induced by epinephrine and stimulated Nrf2. Ginseng reduced upregulation of PKC, NF-κB, and AT1R induced by epinephrine. Ginseng inhibited iNOS and corrected renal disorder in epinephrine model of MI.
The expression of angiotensin II type 1 receptor (AT1 receptor)/protein kinase C (PKC) in heart tissues has a vital role in myocardial infarction (MI). The current work aimed to clarify the renal complication enhanced by MI following epinephrine injection via AT1 receptor/ PKC expression; in addition, the impact of ginseng extract on epinephrine-induced MI and its renal complication was assessed. Adult male albino Wistar rats were pretreated orally with ginseng extract (200 & 400 mg/kg/day) for 14 days, then two successive doses of epinephrine injection (100 mg/kg, i.p.). Epinephrine evoked electrocardiographic (ECG) and renal changes accompanied with a significant increase in heart and kidney contents of malodialdehyde (MDA), nitric oxide (NO), protein kinase C (PKC), heart contents of nuclear factor-kabba B (NF-κB) and angiotensin 1receptor (AT1R), as well as a decrease in heart and kidney reduced glutathione (GSH) and nuclear factor-erythroid-related factor 2 (Nrf2) contents. In histopathological investigations epinephrine exhibited deleterious heart changes in the form of acute MI with the presence of necrosis of cardiomyocytes with iNOS expression and produced glomerulus and renal tubules degeneration. Pretreatment of rats with ginseng extract in both doses significantly corrected epinephrine-induced heart and renal changes. The current work revealed that epinephrine-induced MI associated with aggravated renal complication and ginseng extract has cardio and reno protective role against this as it reduces infarct size, preserves cardiac and renal tissues and functions through activating Nrf2 and down-regulating NF-κB, PKC, AT1R and iNOS.

Abstract
Background As the skin is the largest organ of the human body, it is aging inevitably and produces cosmetic and psychological problems, and even disease. Therefore, the molecular mechanisms related to the prevention of skin aging need to be further explored. Methods Aging models were constructed by D-galactose. Mice were administrated with polygoni multiflori radix preparat (PMRP), PMRP and 3-methyladenine, or PMRP and rapamycin intragastrically. The apparent and viscera index of aged rats was measured. Then, the physicochemical property, antioxidant ability, histological structure, mitochondrial membrane potential, ATP and ROS levels, and mitophagy of aged skins were determined. Finally, the expression of PINK1, Parkin, P62, and LC3II/I; apoptosis-related proteins; and the percentage of apoptotic cells were measured. Results PMRP relieved skin aging with reducing of thymus index, improvement of pathological damage and histological structure, increase of the expression area of fibrous tissue, the ratio of type I to type III collagen, and antioxidant ability of aged skins. Importantly, PMRP also improved mitochondrial dysfunction with an increase in the content of mitochondrial membrane potential and ATP and a decrease of ROS levels. Moreover, mitophagy was enhanced with the treatment of PMRP when observed using electron microscopy, and the expression of PINK1, Parkin, and LC3I/II was increased with PMRP treatment but P62 expression was decreased. Meanwhile, PMRP alleviated apoptosis with a decrease of apoptotic cell and the expression of Cleaved-cas3, Bax, Cyt-c, AIF, and Smac as well as an increase of Bcl-2 expression. Conclusion The results demonstrated that the polygoni multiflori radix preparata may delay skin aging by inducing mitophagy.

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
Aging is an oxidative stress-associated process that progresses with age. Our aim is to delay or attenuate these oxidative alterations and to keep individuals healthy as they age using natural compounds supplementation. Therefore, we conducted the present study to investigate the protective potentials of quercetin against D-galactose (D-gal)-associated oxidative alterations that were induced experimentally in male Wistar rats. Forty-five rats were randomly allocated into five groups of nine rats each. The groups were a control group that was reared on a basal diet and injected subcutaneously with 120 mg D-gal dissolved in physiological saline solution (0.9% NaCl) per kg body weight daily and quercetin-treated groups that received the same basal diet and subcutaneous daily D-gal injections were supplemented orally with 25, 50, and 100 mg of quercetin per kg body weight for 42 days. Pancreatic and renal samples were subjected to histopathological, immunohistochemical, and relative mRNA expression assessments. Aging (p53, p21, IL-6, and IL-8), apoptotic (Bax, CASP-3, and caspase-3 protein), proliferative (Ki67 protein), antiapoptotic (Bcl2 and Bcl2 protein), inflammatory (NF-κB, IL-1β, and TNF-α), antioxidant (SOD1), and functional markers (GCLC and GCLM genes and insulin, glucagon, and podocin proteins) were determined to evaluate the oxidative alterations induced by D-gal and the protective role of quercetin. D-gal caused oxidative alterations of the pancreas and kidneys observed via upregulations of aging, apoptotic, and inflammatory markers and downregulated the antiapoptotic, proliferative, antioxidant, and functional markers. Quercetin potentially attenuated these aging-related oxidative alterations in a dose-dependent manner. Finally, we can conclude that quercetin supplementation is considered as a promising natural protective compound that could be used to delay the aging process and to maintain human health.

Abstract
Despite previous reports of anti-aging effects of Korean red ginseng (KRG), the underlying mechanisms remain poorly understood. Therefore, this study investigated possible mechanisms of KRG-mediated anti-aging effects in aged mice. KRG significantly inhibited thymic involution in old mice. Interestingly, KRG only increased protein expression, but not mRNA expression, of aging-related genes Lin28a, GDF-11, Sirt1, IL-2, and IL-17 in the thymocytes of old mice. KRG also modulated the population of some types of immune cells in old mice. KRG increased the population of regulatory T cells and interferon-gamma (IFN-γ)-expressing natural killer (NK) cells in the spleen of old mice, but serum levels of regulatory T cell-specific cytokines IL-10 and TGF-β were unaffected. Finally, KRG recovered mRNA expression of Lin28a, GDF-11, and Sirt1 artificially decreased by concanavalin A (Con A) in both thymocytes and splenocytes of old mice without cytotoxicity. These results suggest that KRG exerts anti-aging effects by preventing thymic involution, as well as modulating the expression of aging-related genes and immune cell subsets.

Abstract
Advanced glycation end products (AGEs) is a causative factor of various chronic diseases, including chronic kidney disease and atherosclerosis. AGE inhibitors, such as aminoguanidine and pyridoxamine, have the therapeutic activities for reversing the increase in AGEs burden. This study evaluated the inhibitory effects of aucubin on the formation of methylglyoxal (MGO)-modified AGEs in vitro. We also determined the potential activity of aucubin in reducing the AGEs burden in the kidney, blood vessel, heart, and retina of exogenously MGO-injected rats. Aucubin inhibited the formation of MGO-modified AGE-bovine serum albumin (IC50 = 0.57 ± 0.04 mmol/L) and its cross-links to collagen (IC50 = 0.55 ± 0.02 mmol/L) in a dose-dependent manner. In addition, aucubin directly trapped MGO (IC50 = 0.22 ± 0.01 mmol/L) in vitro. In exogenous MGO-injected rats, aucubin suppressed the formation of circulating AGEs and its accumulation in various tissues. These activities of aucubin on the MGO-derived AGEs in vitro and in vivo showed its pharmacological potential for inhibiting AGEs-related various chronic diseases.

Abstract
Context: Maternal diet composition could influence fetal organogenesis. Objective: We investigated effects of high fat diet (HFD) intake alone or combined with omega 3 during pregnancy, lactation and early days of weaning on nephrogenesis of pups and maternal renal function and morphology. Material and methods: Mothers and their pups included in each group were supplied with the same diet composition. Rats were divided into group I, II and III supplied with chow of either 10 kcal%, 45 kcal% or 45 kcal% from fat together with omega-3 respectively. Results: Group II showed increased serum urea and creatinine, renal TNF-α, IL1β. Structural injury was observed in mothers and their pups as Bowman's capsule and tubular dilatation and increased expression of PCNA that were decreased following omega-3 supplementation added to down regulation of Wnt4, Pax2 gene and podocin expression. Discussion and conclusion: Omega-3 supplementation improves lipid nephrotoxicity observed in mothers and their pups.

Abstract
The renal accumulation of advanced glycation end products (AGEs) is a causative factor of various renal diseases, including chronic kidney disease and diabetic nephropathy. AGE inhibitors, such as aminoguanidine and pyridoxamine, have the therapeutic activities for reversing the increase in renal AGE burden. This study evaluated the inhibitory effects of ethyl pyruvate (EP) on methylglyoxal- (MGO-) modified AGE cross-links with proteins in vitro. We also determined the potential activity of EP in reducing the renal AGE burden in exogenously MGO-injected rats. EP inhibited MGO-modified AGE-bovine serum albumin (BSA) cross-links to collagen (IC50 = 0.19 ± 0.03 mM) in a dose-dependent manner, and its activity was stronger than aminoguanidine (IC50 = 35.97 ± 0.85 mM). In addition, EP directly trapped MGO (IC50 = 4.41 ± 0.08 mM) in vitro. In exogenous MGO-injected rats, EP suppressed AGE burden and MGO-induced oxidative injury in renal tissues. These activities of EP on the MGO-mediated AGEs cross-links with protein in vitro and in vivo showed its pharmacological potential for inhibiting AGE-induced renal diseases.

Aging (Albany NY) 2018; 10:4197-4212.

Abstract
The kidney is a typical organ undergoing age and injury. Hyperoside is reported to be useful for preventing aging induced by D-galactose (D-gal). However, therapeutic mechanisms remain unclear. We thereby aimed to verify whether hyperoside, compared to vitamin E (VE), could alleviate renal aging and injury by regulating autophagic activity and its related signaling pathways. In vivo, rats were administered with either hyperoside or VE after renal aging modeling induced by D-gal. Changes in renal aging and injury markers, autophagic activity and AMPK-ULK1 signaling pathway in the kidneys were analysed. In vitro, the NRK-52E cells exposed to D-gal were used to investigate regulative actions of hyperoside and VE on cell viability, renal tubular cellular aging markers, autophagic activity and its related signaling pathways by histomorphometry, immunohistochemistry, immunofluorescence, lentiviral transfection and Western blot. Aging and injury in the kidneys and renal tubular cells induced by D-gal were ameliorated by hyperoside and VE. Hyperoside and VE inhibited autophagic activity through mTOR-independent and AMPK-ULK1 signaling pathways. Hyperoside, as a component of phytomedicine similar to VE, attenuated renal aging and injury induced by D-gal via inhibiting AMPK-ULK1-mediated autophagy. This study provides the first evidence that hyperoside contributes to the prevention of age-associated renal injury.

Abstract
Introduction Purslane (Portulaca oleracea L.) has antioxidant effects. The aim of this study was to evaluate the pancreas protective effect of Purslane hydroalcoholic extract in D-galactose induced aging female mouse model. Methods In this experimental study, 72 adult female mice (30 - 35 g) were obtained and divided into 6 groups: control, Purslane hydroalcoholic extract, D-galactose, D-galactose + Purslane hydroalcoholic extract, Aging, Aging + Purslane hydroalcoholic extract. The aging model induced by subcutaneous injection of D-galactose for 45 consecutive days, and Purslane hydroalcoholic extract was orally gavaged in the last 21 days. 24 hours after the last drug and extract administrations, serum samples and pancreas tissues were removed for biochemical and histological assessments. Results Glucose decreased in the Purslane, D-galactose + Purslane and Aging + Purslane groups (p<0.05). Insulin and HOMA-IR increased in D-galactose and, Aging groups (p<0.05). Furthermore, administration of hydroalcoholic extract of Purslane improved these parameters in D-galactose and Aging treated mice (p<0.05). Diameter of pancreatic islets decreased in Aging and D-galactose groups and Purslane hydroalcoholic extract administration improved this variable. Conclusions The present results show that Purslane has pancreas protective effects via its hypoglycemic and insulin resistance reducing activity.

Kim CS, Jo K, Kim JS, Pyo MK, Kim J. GS-E3D, a new pectin lyase-modified red ginseng extract, inhibited diabetes-related renal dysfunction in streptozotocin-induced diabetic rats. BMC COMPLEMENTARY AND ALTERNATIVE MEDICINE 2017; 17:430. [PMID: 28851327 PMCID: PMC5576329 DOI: 10.1186/s12906-017-1925-7] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/12/2016] [Accepted: 08/14/2017] [Indexed: 01/15/2023]
Abstract
Background GS-E3D is a newly developed pectin lyase-modified red ginseng extract. The purpose of this study was to investigate the therapeutic effects of GS-E3D on diabetes-related renal dysfunction in streptozotocin-induced diabetic rats. Method GS-E3D (25, 50, and 100 mg/kg body weight per day) was administered for 6 weeks. The levels of blood glucose and hemoglobin A1c, and of urinary albumin, 8-hydroxy-2′-deoxyguanosine (8-OHdG), and advanced glycation end-products (AGEs) were determined. Kidney histopathology, renal accumulation of AGEs, and expression of α-smooth muscle actin (α-SMA) were also examined. Results Administration of GS-E3D for 6 weeks reduced urinary levels of albumin, 8-OHdG, and AGEs in diabetic rats. Mesangial expansion, renal accumulation of AGEs, and enhanced α-SMA expression were significantly inhibited by GS-E3D treatment. Oral administration of GS-E3D dose-dependently improved all symptoms of diabetic nephropathy by inhibiting renal accumulation of AGEs and oxidative stress. Conclusion The results of this study indicate that the use of GS-E3D as a food supplement may provide effective treatment of diabetes-induced renal dysfunction.

Abstract
Background Red ginseng is a popularly used traditional medicine with antiaging effects in Asian countries. The present study aimed to explore the changes in protein expression underlying the mechanisms of life span extension and antiaging caused by red ginseng extract (RGE) in Drosophila melanogaster. Methods A proteomic approach of two-dimensional polyacrylamide gel electrophoresis (2-DE) was used to identify the differential abundance of possible target proteins of RGE in D. melanogaster. The reliability of the 2-DE results was confirmed via Western blotting to measure the expression levels of selected proteins. Proteins altered at the expression level after RGE treatment (1 mg/mL) were identified by matrix-assisted laser desorption/ionization-time of flight tandem mass spectrometry and by searching against the National Center for Biotechnology nonredundant and Uniprot protein databases. The differentially expressed proteins were analyzed using bioinformatics methods. Results The average survival life span of D. melanogaster was significantly extended by 12.60% with RGE treatment (1 mg/mL) compared to untreated flies. This followed increased superoxide dismutase level and decreased methane dicarboxylic aldehyde content. Based on the searching strategy, 23 differentially expressed proteins were identified (16 up-regulated and 7 down-regulated) in the RGE-treated D. melanogaster. Transduction pathways were identified using the Kyoto Encyclopedia of Genes and Genomes database, and included the hippo and oxidative phosphorylation pathways that play important roles in life span extension and antiaging process of D. melanogaster. Conclusion Treatment with RGE in D. melanogaster demonstrated that mechanisms of life span extension and antiaging are regulated by multiple factors and complicated signal pathways.

Abstract
The steaming process of Panax ginseng has been reported to increase its major known bioactive components, ginsenosides, and, therefore, its biological properties as compared to regular Panax ginseng. Biological functions of red Panax ginseng attenuating pro-oxidant environments associated with chronic diseases are of particular interest, since oxidative stress can be a key contributor to the pathogenesis of chronic diseases. Additionally, proper utilization of various biomarkers for evaluating antioxidant activities in natural products, such as ginseng, can also be important to providing validity to their activities. Thus, studies on the effects of red ginseng against various diseases as determined in cell lines, animal models, and humans were reviewed, along with applied biomarkers for verifying such effects. Limitations and future considerations of studying red ginseng were been discussed. Although further clinical studies are warranted, red ginseng appears to be beneficial for attenuating disease-associated symptoms via its antioxidant activities, as well as for preventing oxidative stress-associated chronic diseases.
