Abstract
We previously demonstrated that ginsenoside Re (G-Re) has protective effects on acute kidney injury. However, the underlying mechanism is still unclear. In this study, we conducted a meta-analysis and pathway enrichment analysis of all published transcriptome data to identify differentially expressed genes (DEGs) and pathways of G-Re treatment. We then performed in vitro studies to measure the identified autophagy and fibrosis markers in HK2 cells. In vivo studies were conducted using ureteric obstruction (UUO) and aristolochic acid nephropathy (AAN) models to evaluate the effects of G-Re on autophagy and kidney fibrosis. Our informatics analysis identified autophagy-related pathways enriched for G-Re treatment. Treatment with G-Re in HK2 cells reduced autophagy and mRNA levels of profibrosis markers with TGF-β stimulation. In addition, induction of autophagy with PP242 neutralized the anti-fibrotic effects of G-Re. In murine models with UUO and AAN, treatment with G-Re significantly improved renal function and reduced the upregulation of autophagy and profibrotic markers. A combination of informatics analysis and biological experiments confirmed that ginsenoside Re could improve renal fibrosis and kidney function through the regulation of autophagy. These findings provide important insights into the mechanisms of G-Re's protective effects in kidney injuries.

Natural products in traditional Chinese medicine: molecular mechanisms and therapeutic targets of renal fibrosis and state-of-the-art drug delivery systems. Biomed Pharmacother 2024; 170:116039.

Abstract
Renal fibrosis (RF) is the end stage of several chronic kidney diseases. Its series of changes include excessive accumulation of extracellular matrix, epithelial-mesenchymal transition (EMT) of renal tubular cells, fibroblast activation, immune cell infiltration, and renal cell apoptosis. RF can eventually lead to renal dysfunction or even renal failure. A large body of evidence suggests that natural products in traditional Chinese medicine (TCM) have great potential for treating RF. In this article, we first describe the recent advances in RF treatment by several natural products and clarify their mechanisms of action. They can ameliorate the RF disease phenotype, which includes apoptosis, endoplasmic reticulum stress, and EMT, by affecting relevant signaling pathways and molecular targets, thereby delaying or reversing fibrosis. We also present the roles of nanodrug delivery systems, which have been explored to address the drawback of low oral bioavailability of natural products. This may provide new ideas for using natural products for RF treatment. Finally, we provide new insights into the clinical prospects of herbal natural products.

Zhang J, Peng J, Zhang T, Jiang H, Qin Y, Chen H, Deng X, Ren J, Wang P, Xu H. Identification of the Main Chemical constituents and mechanism of Renshen Guben oral liquid against Renal Fibrosis. Chin Med 2023; 18:56. [PMID: 37198665 DOI: 10.1186/s13020-023-00762-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/16/2023] [Accepted: 05/01/2023] [Indexed: 05/19/2023] Open
Abstract
BACKGROUND Renal fibrosis is the late stage of many chronic kidney diseases (CKD). Clinically, there is almost no effective treatment for renal fibrosis except dialysis. Renshen Guben oral liquid (RSGB) is a Chinese patent medicine approved by National Medical Products Administration (NMPA), which is suitable for clinical patients with chronic nephritis. Currently, the chemical constituents of RSGB remains unclear, and its efficacy and mechanism on renal fibrosis have not been reported. METHODS In our research, ultra-high performance liquid chromatography/quadrupole time-of-flight mass spectrometry (UPLC-QTOF-MS/MS) was employed to describe the chemical profile of RSGB, unilateral ureteral obstruction (UUO) model in mice was established to evaluate the beneficial effect of RSGB on renal fibrosis by biochemical indexes, HE and Masson staining. RNA sequencing and "constituents-targets-pathways" multi-dimensional network was established to mine the mechanisms of RSGB. Key targets were verified by quantitative real-time PCR (qRT-PCR) and western bolt (WB). RESULTS A total of 201 constituents were identified or tentatively characterized, 15 of which were confirmed with standards. The number of triterpenes was the highest with 49, followed by phenols with 46. RSGB ameliorated the blood urea nitrogen (BUN) and serum creatinine (Scr) levels in serum, normalizing pathological structure of kidney tissue. RNA sequencing revealed that RSGB regulates 226 differential genes, which were involved in kidney development. According to the "constituents-targets-pathways" network, 26 key active constituents may mainly regulate the inflammatory immune system through 88 corresponding targets. qRT-PCR and WB results showed that RSGB inhibited the activation of the Tgfβ1/Smad2/3 pathway, Wnt4/β-Catenin pathway and NGFR/NF-κB pathway. CONCLUSIONS Overall, our study, for the first time, characterized 201 chemical constituents in RSGB, and 26 of them were screened out to alleviates renal fibrosis mainly through Tgfβ1/Smad2/3 pathway, Wnt4/β-catenin pathway and NGFR/NF-κB pathway, which may provide a new research strategy for research on the mechanism of traditional Chinese Medicine.

Lipids Health Dis 2023; 22:22. [PMID: 36759837 PMCID: PMC9912620 DOI: 10.1186/s12944-023-01787-2] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/29/2022] [Accepted: 02/02/2023] [Indexed: 02/11/2023] Open
Abstract
BACKGROUND Nonalcoholic steatohepatitis (NASH) is one of the most frequent liver diseases at present, and there is no radical treatment. The consequences of a variety of ginsenoside compounds on this situation have before been reported, however, the specific effect on the monomeric ginsenoside Rg1 (Rg1) and its associated underlying molecular mechanism stay unknown. MATERIAL AND METHODS In vitro, the cell models were constructed by exposing free fatty acids (FFAs) to HepG2 cells. A methionine and choline deficiency (MCD)-induced NASH mouse model was also established over 5-6 weeks of treatment. Rg1 is a traditional Chinese medicine monomer. These NASH models were treated with Rg1 and analyzed by qRT-PCR, Western Blot, sequencing, Oil red O staining, immunofluorescence, enzyme activity, HE staining, ELISA, double luciferase reporter assay, and immunohistochemistry. RESULTS Overexpression of ATG2B, an autophagy-related protein, attenuated lipid droplet accumulation and reduces ALT, AST, inflammatory cytokines, hydrogen peroxide, and pyroptosis in established mouse and cellular models of NASH and increased levels of ATP and autophagy. The binding sites of miR-375-3p and ATG2B were verified by bioinformatic prediction and a dual-luciferase reporter gene. Knockdown of miR-375-3p promoted autophagy and inhibited pyroptosis. ATG2B knockdown substantially attenuated the impact of miR-375-3p on NASH. Rg1 appears to regulate the occurrence and development of NASH inflammation through miR-375-3p and ATG2B in vitro and in vivo, and is regulated by PTEN-AKT pathway. CONCLUSIONS This study showed that Rg1 participates in autophagy and pyroptosis through the miR-375-3p/ATG2B/PTEN-AKT pathway, thereby alleviating the occurrence and development of NASH, for that reason revealing Rg1 as a candidate drug for NASH.

ENVIRONMENTAL TOXICOLOGY 2022; 37:2302-2313.

Abstract
Paraquat (PQ), as a widely used herbicide, is highly toxic to human. PQ-induced pulmonary fibrosis is the main reason for respiratory failure and death. In PQ-poisoned mice, we find abundant senescent epithelial cells in the lung tissues, which can contribute to the activation of pulmonary fibroblasts. Ginsenoside Rg1 (Rg1), the main active component of ginseng, possess beneficial properties against aging. In our work, we aimed to investigate the potential protective effects of Rg1 on PQ-induced pulmonary fibrosis and the underlying mechanism. In vivo, the treatment of Rg1 can attenuate PQ-induced pulmonary fibrosis and decrease senescence and senescence associated secretory phenotype (SASP) expression. In vitro, Rg1 can effectively eliminate senescent cells via apoptosis, but not normal cells. In addition, we demonstrate that Rg1 can enhance autophagy activity via inducing the expression of ATG12. Inhibition of autophagy via 3-MA or transfection of the siRNA targeting ATG12 can impair the antiaging effect of Rg1. Taken together, our data implicates that Rg1 can protect pulmonary epithelial cells from PQ-induced cellular senescence in an ATG12 dependent manner, which may provide a preventive and therapeutic strategy for PQ poisoning-induced pulmonary fibrosis.

Abstract
Chronic exposure to aristolochic acid (AA) leads to renal interstitial fibrosis and nephropathy. In this study, we aimed to investigate the renoprotective effects of Panax ginseng extract (GE) and ginsenoside saponin (GS) on AA-induced nephropathy (AAN) in mice. Eighty female C3H/He mice were randomly divided into eight groups, including normal; AA (3 μg/mL for 56 days); AA with GE (125, 250, or 500 mg/kg/d for 14 days); and AA with important GE ingredients, Rg1, Rb1, or Rd (5 mg/kg/d for 14 days). Compared with the AA group, renal injuries were significantly decreased in the GE (250 mg/kg/d), Rb1, and Rg1 treatment groups. Rg1 exhibited the best renoprotection among all GS-treated groups. There were 24 peaks significantly altered among normal, AA, and AA + Rg1 groups, and four mitochondrial proteins were identified, including acyl-CoA synthetase medium-chain family member 2, upregulated during skeletal muscle growth 5 (Usmg5), mitochondrial aconitase 2 (ACO2), and cytochrome c oxidase subunit Va preprotein (COX5a). We demonstrated for the first time that the AAN mechanism and renoprotective effects of Rg1 are associated with expression of mitochondrial proteins, especially ACO2, Usmg5, and COX5a.

Abstract
Background: Severe hepatitis is a common cause of chronic or acute liver disease and autophagy might play an important role in cellular response to inflammation and injury. It has been reported that Ginsenoside-Rg1 (G-Rg1) has strong hepatoprotective effects for acute liver injury, but its protective mechanisms have not yet been elucidated. This study aims to explore the detailed molecular mechanisms of G-Rg1 on acute liver injury via autophagy. Methods: The role of G-Rg1 by autophagic induction was studied in the mouse model of acute liver injury which induced by carbon tetrachloride (CCl4). Liver function, inflammatory reaction and apoptosis were detected when autophagy has been inhibited by 3-MA or stimulated by RPA. MCC950 and ATP were applied to investigate the role of NLRP3 inflammasome in acute liver injury. The differential expression of NF-κB, NLRP3 inflammasome, caspase 1, caspase 3, IL-1β, IL-18, LC3-I, LC3-II, Beclin-1, PINK1 and Parkin have been detected by the quantitative real-time polymerase chain reaction (qRT-PCR) and Western blot. Results: G-Rg1 could decrease ALT, AST, TNF-α, IL-1β and IL-6 in mice with CCl4-induced acute liver injury. The change of autophagy and apoptosis after the treatment of 3-MA or RPA demonstrated that the autophagy played a key role in the protective effect of G-Rg1 in acute liver injury. The enhancement of G-Rg1 promoted-autophagy resulted in the significant decrease in NF-κB, NLRP3 inflammasome, caspase 1, caspase 3, IL-1β and IL-18, which suggesting that NF-κB/NLRP3 inflammasome signaling pathway was associated with the autophagy induced by G-Rg1 in acute liver injury. Conclusion: G-Rg1 ameliorated acute liver injury via the autophagy, which may be related to NF-κB/NLRP3 inflammasome signaling pathway.

Abstract
Background Ginseng (Panax ginseng C. A. Meyer), a representative Chinese herbal medicine, can improve the body’s antioxidant and anti-inflammatory capacity. Recently, scientists have shifted emphasis towards the initial stages of different malignant diseases—corresponding organ fibrosis and explored the essential role of P. ginseng in the treatment of fibrotic diseases. Main body In the first instance, the review generalizes the molecular mechanisms and common therapeutic methods of fibrosis. Next, due to the convenience and safety of individual medication, the research progress of ginseng extract and formulas in treating liver fibrosis, pulmonary fibrosis, myocardial fibrosis, and renal fibrosis has been systematically summarized. Finally, we describe active ingredients isolated from P. ginseng for their outstanding anti-fibrotic properties and further reveal the potential therapeutic prospect and limitations of P. ginseng in fibrotic diseases. Conclusions P. ginseng can be regarded as a valuable herbal medicine against fibrous tissue proliferation. Ginseng extract, derived formulas and monomers can inhibit the abundant deposition of extracellular matrix which caused by repeated damage and provide protection for fibrotic organs. Although the molecular mechanisms such as transforming growth factor β signal transduction have been confirmed, future studies should still focus on exploring the underlying mechanisms of P. ginseng in treating fibrotic disease including the therapeutic targets of synergistic action of multiple components in P. ginseng. Moreover, it is also necessary to carry out clinical trial to evaluate the feasibility of P. ginseng in combination with common fibrosis drugs.

Abstract
Aging is closely related to the progress of renal fibrosis, which eventually results in renal dysfunction. Ginsenoside Rg1 (Rg1) has been reported to have an extensive anti-aging effect. However, the role and mechanism of Rg1 in aging-related renal fibrosis remain unclear. The present study aimed to evaluate the protective effect and mechanism of Rg1 in renal fibrosis during kidney aging in a model of SAMP8 mice. Taking SAMR1 mice as the control group, SAMP8 mice were administered Apocynin (50 mg/kg), Tempol (50 mg/kg), or Rg1 (5, 10 mg/kg) intragastrically for 9 weeks as treatment groups. The results showed that the elevated levels of blood urea nitrogen, serum creatinine and senescence-associated β-galactosidase (β-Gal) were markedly decreased, the glomerular mesangial proliferation was significantly alleviated and the increased levels of collagen IV and TGF-β1 were significantly downregulated by Rg1 in SAMP8 mice. In addition, the generation of ROS and the expression of NADHP oxidase 4 (NOX4) in the renal cortex were significantly reduced by Rg1 treatment. The expression levels of NLRP3 inflammasome-related proteins and the inflammation-related cytokine IL-1β were also inhibited by Rg1 treatment in the SAMP8 mice. These results suggested that Rg1 could delay kidney aging and inhibit aging-related glomerular fibrosis by reducing NOX4-derived ROS generation and downregulating NLRP3 inflammasome expression.

Abstract
Tissue fibrosis is an eventual pathologic change of numerous chronic illnesses, which is characterized by resident fibroblasts differentiation into myofibroblasts during inflammation, coupled with excessive extracellular matrix deposition in tissues, ultimately leading to failure of normal organ function. Now, there are many mechanistic insights into the pathogenesis of tissue fibrosis, which facilitate the discovery of effective antifibrotic drugs. Moreover, many chronic diseases remain a significant clinical unmet need. For the past five years, many research works have undoubtedly addressed the functional dependency of ginsenosides in different types of fibrosis and the successful remission in various animal models treated with ginsenosides. Caveolin-1, interleukin, thrombospondin-1 (TSP-1), liver X receptors (LXRs), Nrf2, microRNA-27b, PPARδ-STAT3, liver kinase B1 (LKB1)-AMPK, and TGF-β1/Smads are potential therapy targeting using ginsenosides. Ginsenosides can play a targeting role and suppress chronic inflammatory response, collagen deposition, and epithelial-mesenchymal transition (EMT), as well as myofibroblast activation to attenuate fibrosis. In this report, our aim was to focus on the therapeutic prospects of ginsenosides in fibrosis-related human diseases making use of results acquired from various animal models. These findings should provide important therapeutic clues and strategies for the exploration of new drugs for fibrosis treatment.

Abstract
Introduction Anti-oxidative stress and inhibition of TGF-β1/Smads signaling cascade are essential therapeutic strategies for diabetic nephropathy (DN). In this study, we aimed to explore the effect of combination of Ginsenoside Rg1 and Astragaloside IV on oxidative stress and TGF-β1/Smads signaling in DN rats. Materials and methods Wistar rats were divided into five groups: N group, M group (streptozotocin [STZ], intraperitoneally), G group (STZ rats with Ginsenoside Rg1, intragastrically [ig]), A group (STZ rats with Astragaloside IV, ig) and C group (STZ rats with Ginsenoside Rg1 and Astragaloside IV, ig). The levels of methane dicarboxylic aldehyde (MDA), catalase (CAT), glutathione peroxidase (GSH-PX), total anti-oxidative capacity (T-AOC), blood urea nitrogen (BUN), β2-microglobulin (β2-MG), serum creatinine (SCr) and urinary creatinine (UCr) were detected in all the groups. The left kidneys of the rats were harvested to detect the expression of TGF-β1, Smad2/3, Smad7 and CTGF by immunohistochemical staining, while the right kidneys were used to detect the mRNA expression of TGF-β1, Smad7 and CTGF by real-time PCR. Results Rats in G group, A group and C group had lower level of MDA but higher levels of CAT, GSH-PX and T-AOC compared with rats in M group. Rats in C group showed the best anti-oxidative stress level. G group, A group and C group treatments significantly decreased the levels of BUN, SCr, β2-MG and UCr. In addition, C group treatment showed the best kidney protective effect. G group, A group and C group treatments significantly diminish ED both factor and mRNA overexpression of TGF-β1 and CTGF but increase Smad7 expression in kidney tissue. Conclusion The combination of Ginsenoside Rg1 and Astragaloside IV may potentially protect against DN by reducing oxidative stress and inhibiting TGF-β1/Smads signaling cascade.

Abstract
Most therapeutic attempts to prevent the progression of kidney diseases have been based on interventions to inhibit the production of transforming growth factor-β (TGF-β). Thrombospondins (TSPs) play an important role in activating TGF-β. In the healthy kidney, two TSPs are expressed, TSP1 and TSP2, which exert contrasting effects. While TSP1 is a major activator of TGF-β in renal cells and exerts pro-inflammatory effects both in vitro and in vivo, TSP2 lacks the ability for TGF-β activation but regulates matrix remodeling and inflammation in experimental kidney disease. The effects of TSPs in the kidney have been mostly investigated by using the murine model of unilateral ureteral obstruction. In this model, TSP1 expression is increased along with the development of interstitial fibrosis and TGF-β. Relief of the obstruction gradually improves renal function and decreases the expression in TSP1 and TGF-β1. Several inhibitors of TSP1 prevented progressive interstitial fibrosis in murine models of ureteral obstruction, suggesting that control of latent TGF-β activation by inhibiting TSP1 might represent a novel potential target for preventing renal interstitial fibrosis. However, further studies are needed to assess whether TSP1-mediated TGF-β activation can be safely used in humans. In fact, TSPs normally act to suppress tumors in vivo. Moreover, TGF-β can exert a pivotal function in the immune system, as it may induce the production of regulatory T cells and suppress B cell responses. Knowledge of the molecular mechanisms involved in TGF-β regulation may help in finding effective treatments of tissue fibrosis, cancer and autoimmune disease.

Abstract
Ginsenoside Rg1 (G-Rg1) is an active ingredient of Panax ginseng, which has previously been reported to attenuate alcohol-induced hepatic damage; however, the underlying mechanisms remain largely unknown. The present study aimed to investigate the protective effects of G-Rg1 on alcohol-induced cell injury in vitro and on a rat model of alcoholic hepatitis in vivo. For the in vitro model, L-O2 cells were incubated with ethanol in the presence or absence of G-Rg1. For the in vivo model, rats were administered ethanol by intragastric injection and were treated with G-Rg1, or dexamethasone as a control. The results indicated that serum biochemical parameters, including alanine aminotransferase, aspartate aminotransferase and total bilirubin, as well as the expression of nuclear factor (NF)-κB pathway-associated inflammatory cytokines, including interleukin (IL)-6, tumor necrosis factor-α and IL-1β, were elevated in response to alcohol; however, they were significantly decreased by G-Rg1 treatment. Furthermore, NF-κB pathway activation was reduced by treatment with G-Rg1. G-Rg1 also decreased oxidative stress by inhibiting cytochrome P450 2E1 expression and reactive oxygen species production, and promoting glutathione peroxidase expression. Furthermore, G-Rg1 inhibited the expression levels of caspase-3 and -8, which may be associated with decreased hepatocyte apoptosis. These data suggested that G-Rg1 may protect hepatocytes against alcohol-induced injury, through preventing excessive inflammation and hepatocellular apoptosis.

Abstract
BACKGROUND AND ETHNOPHARMACOLOGICAL RELEVANCE Ginseng has been used as efficient tonic and for the treatment of various diseases including hepatic disorders. Ginseng saponins, also known as ginsenosides, are principal constituents and have been treated to be responsible for disparate ginseng health benefits. The current review mainly focuses on ginsenoside Rg1, a compound isolated from traditional Chinese herbal medicine Panax ginseng Meyer. AIMS To summary the hepataprotective effects and related mechanisms of ginsenoside Rg1, we conclude this review by combining the literature and our own researches. METHODS As evidenced, we organized the pharmacological function of ginsenoside Rg1 by searching the pubmed. It has been deeply studied and summarized in the field of neurobiology, however, in this paper we described the pharmacological function of Rg1 in liver related to antioxidative stress and anti-inflammation. R&D: Individual ginsenoside could be used since it shows a wide array of beneficial functions in the regulation and disorders of acute and chronic hepatotoxicity, hepatitis, hepatic fibrosis and cirrhosis in various pathways and different mechanisms. Of note, the antioxidant hepatic protection of ginsenoside Rg1 is mainly through the induction of Keap1-Nrf2-ARE signaling pathway. CONCLUSION The multi-target actions of Rg1 substantiates it as a promising drug candidate for the treatment of hepatic impairment in different factors induced liver diseases.

Ginsenoside Rg1 Ameliorates Cigarette Smoke-Induced Airway Fibrosis by Suppressing the TGF- β1/Smad Pathway In Vivo and In Vitro. BIOMED RESEARCH INTERNATIONAL 2017; 2017:6510198.

Abstract
Small airway fibrosis is a key pathological process accompanying chronic obstructive pulmonary disease (COPD) and includes fibroblast/myofibroblast transdifferentiation and excessive extracellular matrix deposition. Ginsenoside Rg1, one of the main active ingredients of Panax ginseng, has been shown to exert an antifibrotic effect in many tissues. However, little is known about the underlying mechanism and whether ginsenoside Rg1 can exert an effect on small airway fibrosis. We investigated the anti-small airway fibrosis effects of ginsenoside Rg1 in human embryonic lung fibroblasts and in COPD rats. We found that ginsenoside Rg1 effectively reduced the degree of pulmonary fibrosis, decreased the expression of α-smooth muscle actin, collagen I, and matrix metalloproteinase 9, and maintained the ratio of matrix metalloproteinase 9 to tissue inhibitor of metalloproteinase 1. Importantly, ginsenoside Rg1 significantly attenuated cigarette smoke extract-induced upregulation of transforming growth factor β1, TGF-β receptor I, phospho-Smad2, and phospho-Smad3. In addition, ginsenoside Rg1 mimicked the effect of SB525334, a TGF-β receptor I-Smad2/3 inhibitor. Collectively, these results suggest that ginsenoside Rg1 may suppress cigarette smoke-induced airway fibrosis in pulmonary fibroblasts and COPD rats by inhibiting the TGF-β1/Smad signaling pathway.

Abstract
Hypertension is an independent risk factor for the progression of chronic renal failure, and oxidative stress plays a critical role in hypertensive renal damage. Forkbox O1(FoxO1) signaling protects cells against oxidative stress and may be a useful target for treating oxidative stress-induced hypertension. Tongxinluo is a traditional Chinese medicine with cardioprotective and renoprotective functions. Therefore, this study aimed to determine the effects of Tongxinluo in hypertensive renal damage in spontaneously hypertensive rats(SHRs)and elucidate the possible involvement of oxidative stress and FoxO1 signaling in its molecular mechanisms. SHRs treated with Tongxinluo for 12 weeks showed a reduction in systolic blood pressure. In addition to increasing creatinine clearance, Tongxinluo decreased urinary albumin excretion, oxidative stress injury markers including malondialdehyde and protein carbonyls, and expression of nicotinamide adenine dinucleotide phosphate oxidase subunits and its activity in SHR kidneys. While decreasing phosphorylation of FoxO1, Tongxinluo also inhibited the phosphorylation of extracellular signal-regulated kinase1/2 and p38 and enhanced manganese superoxide dismutase and catalase activities in SHR kidneys. Furthermore, histology revealed attenuation of glomerulosclerosis and renal podocyte injury, while Tongxinluo decreased the expression of α-smooth muscle actin, extracellular matrixprotein, transforming growth factor β1 and small mothers against decapentaplegic homolog 3,and improved tubulointerstitial fibrosis in SHR kidneys. Finally, Tongxinluo inhibited inflammatory cell infiltration as well as expression of tumor necrosis factor-α and interleukin-6. In conclusion, Tongxinluo protected SHRs against hypertension-induced renal injury by exerting antioxidant, antifibrotic, and anti-inflammatory activities. Moreover, the underlying mechanisms of these effects may involve inhibition of oxidative stress and functional activation of FoxO1 signaling.

Abstract
INTRODUCTION This study tested the effect of ginsenoside Rg1 (G-Rg1) in cyclosporin A (CsA)-induced endoplasmic reticulum (ER) stress on renal tubular cell apoptosis in a rat model of chronic CsA nephropathy. MATERIALS AND METHODS Twenty-two Sprague-Dawley rats were randomized into 3 groups: a control group, a model group (CsA 25 mg/kg per day), and a G-Rg1 treatment group (CsA 25 mg/kg per day and G-Rg1 20 mg/kg per day). We examined the effects of G-Rg1 on histopathology, terminal deoxynucleotidyl transferase dUTP nick-end labeling staining, and expression of glucose-regulated protein 78, CCAAT/enhancer-binding protein homologous protein, and caspase-3 by using Western blot analysis. RESULTS G-Rg1 attenuated CsA-induced tubulointerstitial fibrosis and reduced tubular epithelial cell apoptosis as assessed by terminal deoxynucleotidyl transferase dUTP nick-end labeling staining and caspase-3 expression. Compared with the model group, it reduced the expression of glucose-regulated protein 78 and CCAAT/enhancer-binding protein homologous protein (0.12 ± 0.03 vs 0.48 ± 0.05 [P < .01]; 0.55 ± 0.11 vs 1.08 ± 0.07 [P < .05]), respectively. CONCLUSIONS G-Rg1 mitigates the progression of chronic CsA nephropathy, at least in part, through inhibition of ER stress-triggered tubular cell apoptosis.

Abstract
BACKGROUND AND PURPOSE Interstitial lung disease accounts for a group of chronic and progressive disorders associated with severe pulmonary vascular remodelling, peripheral vascular rarefaction and fibrosis, thus limiting lung function. We have previously shown that Akt is necessary for myofibroblast differentiation, a critical event in organ fibrosis. However, the contributory role of the Akt-mTOR pathway in interstitial lung disease and the therapeutic benefits of targeting Akt and mTOR remain unclear. EXPERIMENTAL APPROACH We investigated the role of the Akt-mTOR pathway and its downstream molecular mechanisms in chronic hypoxia- and TGFβ-induced pulmonary vascular pruning and fibrosis in mice. We also determined the therapeutic benefits of the Akt inhibitor triciribine and the mTOR inhibitor rapamycin for the treatment of pulmonary fibrosis in mice. KEY RESULTS Akt1(-) (/) (-) mice were protected from chronic hypoxia-induced peripheral vascular pruning. In contrast, hyperactivation of Akt1 induced focal fibrosis similar to TGFβ-induced fibrosis. Pharmacological inhibition of Akt, but not the Akt substrate mTOR, inhibited hypoxia- and TGFβ-induced pulmonary vascular rarefaction and fibrosis. Mechanistically, we found that Akt1 modulates pulmonary remodelling via regulation of thrombospondin1 (TSP1) expression. Hypoxic Akt1(-) (/) (-) mice lungs expressed less TSP1. Moreover, TSP1(-) (/) (-) mice were resistant to adMyrAkt1-induced pulmonary fibrosis. CONCLUSIONS AND IMPLICATIONS Our study identified Akt1 as a novel target for the treatment of interstitial lung disease and provides preclinical data on the potential benefits of the Akt inhibitor triciribine for the treatment of interstitial lung disease.

Abstract
AIM Endoplasmic reticulum (ER) stress and unfolded protein response (UPR) are implicated in many fibrotic diseases, including renal fibrosis. Whether Ginsenoside-Rg1 (G-Rg1) could attenuate renal fibrosis via suppression of ER stress and UPR has not been reported. The aim of this study was to explore the effect of G-Rg1 on ER stress and UPR-induced apoptosis in kidneys with unilateral ureteral obstruction (UUO) rat model. METHODS Twenty-four male Sprague-Dawley rats were randomly divided into control group, model group and G-Rg1 treatment group. G-Rg1 was administered to rats by intraperitoneal injection. Renal interstitial fibrosis in the model group was developed by UUO in rats. Renal function was estimated by the levels of serum creatinine (Scr) and blood urea nitrogen (BUN). Renal pathological damage was evaluated by hematoxylin and eosin (HE) and Masson's trichrome staining. The ER stress was assessed with glucose-regulated protein (GRP) 78 expression, and the proapoptotic response was detected with CCAAT/enhancer-binding protein homologous protein (CHOP) and caspase-12 expressions by Western Blot. The number of apoptotic cells was determined by Terminal-deoxynucleotidyl Transferase Mediated Nick End Labeling (TUNEL) analysis. RESULTS UUO for 14 days aggravated renal function, renal damage and renal interstitial fibrosis, activated ER stress response (induction of GRP78 protein), enhanced the proapoptotic response (increase in CHOP and caspase-12 proteins) and increased the number of apoptotic cells (shown by the TUNEL assay). Treatment with G-Rg1 significantly ameliorates the renal pathological lesions and decreases expressions of ER stress-associated proteins and the level of apoptotic cells in kidneys. CONCLUSION G-Rg1 suppresses renal cell apoptotic and fibrotic process partly through inhibition of ERS- and UPR-related apoptotic pathway in the kidneys after UUO.

[PMID: 25380391 DOI: 10.1002/ptr.5254] [Citation(s) in RCA: 46] [Impact Index Per Article: 4.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2014] [Revised: 09/25/2014] [Accepted: 10/10/2014] [Indexed: 12/24/2022]
Abstract
This study was designed to investigate the effects of mangiferin on renal fibrosis, osteopontin production, and inflammation in the kidney of diabetic rats. Diabetes was induced through the single administration of streptozotocin (55 mg/kg, i.p.). Diabetic rats were treated with mangiferin (15, 30, and 60 mg/kg/day, i.g.) for 9 weeks. The kidney was fixed in 10% formalin for glomerulus fibrosis examination using Masson trichrome staining. Kidney and blood were obtained for assays of the associated biochemical parameters. Chronic mangiferin treatment prevented renal glomerulus fibrosis evidenced by decreases in Mason-stained positive area of glomeruli, protein expression of type IV collagen, and α-smooth muscle actin in the kidney of diabetic rats, in comparison with decreases in mRNA and protein expression of osteopontin as well as protein expression of cyclooxygenase 2 and NF-кB p65 subunit in the renal cortex of diabetic rats. Moreover, mangiferin reduced the levels of interleukin 1β in both the serum and the kidney of diabetic rats. Our findings demonstrate that mangiferin prevents the renal glomerulus fibrosis of diabetic rats, which is realized through the suppression of osteopontin overproduction and inflammation likely via inactivation of NF-кB.

Ginsenosides Rg1 from Panax ginseng: A Potential Therapy for Acute Liver Failure Patients? EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2014; 2014:538059. [PMID: 25431611 PMCID: PMC4241314 DOI: 10.1155/2014/538059] [Citation(s) in RCA: 19] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/09/2014] [Revised: 09/09/2014] [Accepted: 09/26/2014] [Indexed: 11/17/2022]
Abstract
Acute liver failure (ALF) is a rapidly progressing critical illness with a high mortality rate. Circulating inflammatory cytokines, such as tumor necrosis factor-α (TNF-α), play a significant role in the pathophysiology of ALF through promoting hepatocellular apoptosis. Ginsenoside Rg1, the primary active ingredient in Panax ginseng (also termed Asian or Korean ginseng), has been reported to inhibit TNF-α production and has been shown to significantly attenuate liver fibrosis development. Here, we assessed ginsenoside Rg1's potential as a therapy for ALF by investigating the effect of ginsenoside Rg1 treatment on circulating inflammatory markers, hepatocellular apoptosis, and relevant apoptotic signaling pathways in a well-established murine ALF model. We found that ginsenoside Rg1 significantly reduces liver damage in a murine ALF model through inhibiting TNF-α-induced, caspase-dependent hepatocellular apoptosis. These results support the further investigation of ginsenoside Rg1 as a therapeutic candidate for ALF.

Abstract
Diabetic nephropathy is one of the serious complications in patients with either type 1 or 2 diabetes mellitus but current treatments remain unsatisfactory. Results of clinical research studies demonstrate that Panax ginseng can help adjust blood pressure and reduce blood sugar and may be advantageous in the treatment of tuberculosis and kidney damage in people with diabetes. The heat-processing method to strengthen the efficacy of P. ginseng has been well-defined based on a long history of ethnopharmacological evidence. The protective effects of P. ginseng on pathological conditions and renal damage associated with diabetic nephropathy in the animal models were markedly improved by heat-processing. The concentrations of less-polar ginsenosides (20(S)-Rg3, 20(R)-Rg3, Rg5, and Rk1) and maltol in P. ginseng were significantly increased in a heat-processing temperature-dependent manner. Based on researches in animal models of diabetes, ginsenoside 20(S)-Rg3 and maltol were evaluated to have therapeutic potential against diabetic renal damage. These effects were achieved through the inhibition of inflammatory pathway activated by oxidative stress and advanced glycation endproducts. These findings indicate that ginsenoside 20(S)-Rg3 and maltol are important bioactive constituents of heat-processed ginseng in the control of pathological conditions associated with diabetic nephropathy.

Abstract
Prohibitins PHB1 and PHB2 are evolutionary conserved and pleiotropic proteins, which have been shown to be important factors in various cellular functions, including proliferation, tumour suppression, apoptosis, transcription, and mitochondrial protein folding. Recently, we demonstrated that down-regulation promoted renal interstitial fibrosis (RIF) in ureteral obstructed rats. Furthermore, the hypoxic conditions and oxidative stress have been implicated in obstruction-mediated renal disease. This study was performed to explore the association of PHBs with oxidative stress in a rat model of RIF. PHBs, the pro-fibrotic transforming growth factor-β1 (TGF-β1), and the extracellular matrix proteins collagen-IV (Col-IV) and fibronectin (FN) were evaluated, as were markers of oxidative stress [total reactive oxygen species (ROS), malondialdehyde (MDA)] and antioxidative capacity (superoxide dismutase, glutathione), and apoptosis. Our results showed a progressive increase in oxidative stress and concomitant decrease in antioxidants over a period of 4 weeks ureteral obstruction. Concomitantly, profibrotic components increased and PHB expression decreased. Overall, both PHBs were negatively correlated with the extent of observed fibrosis, TGF-β1, Col-IV, FN, ROS, MDA, and apoptosis.

Abstract
BACKGROUND Unbalanced inflammatory response and lymphocyte apoptosis are the main reasons for high mortality in patients with sepsis. Ginsenoside Rg1 (Rg1), the most important component isolated from Panax ginseng, has long been used to treat inflammatory and immune-related diseases. We designed this study to investigate the therapeutic effect of this agent on cecal ligation and puncture (CLP)-induced sepsis in mice. MATERIALS AND METHODS We randomly divided C57BL/6 mice into four experimental groups: sham, sham plus Rg1, CLP, and CLP plus Rg1. We intravenously injected Rg1 (20 mg/kg) 1 h after CLP and evaluated survival, bacterial clearance, cytokine production, histology, neutrophil emigration, and lymphocyte apoptosis. RESULTS Our study showed that treatment with Rg1 significantly improved survival in septic mice (P < 0.01). Rg1 administration suppressed the inflammatory response and enhanced bacterial clearance. Histologic examination of lung and liver showed only minor abnormalities in mice that received Rg1. In addition, Rg1 increased neutrophil counts in peritoneal cavity and inhibited lymphocyte apoptosis in thymus and spleen. CONCLUSIONS Ginsenoside Rg1 has a protective role against CLP-induced polymicrobial sepsis by attenuating the proinflammatory response, enhancing innate immunity and preserving adaptive immunity. Rg1 could be a promising new agent for treatment of sepsis.

Abstract
Prohibitin (PHB) and paired box 2 (PAX2) are associated with the development of renal interstitial fibrosis (RIF). This study was performed to investigate whether or not the PHB could regulate the PAX2 gene expression in unilateral ureteral obstruction (UUO) in rats. Eighty Wistar male rats were randomly divided into two groups: sham operation group (SHO) and model group subjected to unilateral ureteral obstruction (GU), n = 40, respectively. The model was established by left ureteral ligation. Renal tissues were collected at 14-day and 28-day after surgery. RIF index, protein expression of PHB, PAX2, transforming growth factor-βl (TGF-β1), α-smooth muscle actin (α-SMA), collagen-IV (Col-IV), fibronectin (FN) or cleaved Caspase-3, and cell apoptosis index in renal interstitium, and mRNA expressions of PHB, PAX2 and TGF-β1 in renal tissue were detected. When compared with those in SHO group, expression of PHB (mRNA and protein) was significantly reduced, and expressions of PAX2 and TGF-β1 (protein and mRNA) were markedly increased in the GU group (each p < 0.01). Protein expressions of α-SMA, Col-IV, FN and cleaved Caspase-3, and RIF index or cell apoptosis index in the GU group were markedly increased when compared with those in the SHO group (each p < 0.01). The protein expression of PHB was negatively correlated with protein expression of PAX2, TGF-β1, α-SMA, Col-IV, FN or cleaved Caspase-3, and RIF index or cell apoptosis index (all p < 0.01). In conclusion, less expression of PHB is associated with increased PAX2 gene expression and RIF index in UUO rats, suggesting that increasing the PHB expression is a potential therapeutic target for prevention of RIF.

Abstract
Background Shuanglong formula (SLF), a Chinese medicine composed of panax ginseng and salvia miltiorrhiza exhibited significant effect in the treatment of myocardial infarction (MI) in clinical. Because of the complex nature and lack of stringent quality control, it's difficult to explain the action mechanism of SLF. Method In this study, we present a "system to system" (S2S) mode. Based on this mode, SLF was simplified successively through bioactivity-guided screening to achieve an optimized minimal phytochemical composition (new formula NSLF6) while maintaining its curative effect for MI. Results Pharmacological test combining with the study of systems biology show that NSLF6 has activity for treatment MI through synergistic therapeutic efficacies between total ginsenosides and total salvianolic acids via promoting cardiac cell regeneration and myocardial angiogenesis, antagonistic myocardial cell oxidative damage. Conclusions The present S2S mode may be an effective way for the discovery of new composite drugs from traditional medicines.
