Abstract
Heart failure with preserved ejection fraction (HFpEF) is a complex clinical syndrome with cardiac dysfunction, fluid retention and reduced exercise tolerance as the main manifestations. Current treatment of HFpEF is using combined medications of related comorbidities, there is an urgent need for a modest drug to treat HFpEF. Geniposide (GE), an iridoid glycoside extracted from Gardenia Jasminoides, has shown significant efficacy in the treatment of cardiovascular, digestive and central nervous system disorders. In this study we investigated the therapeutic effects of GE on HFpEF experimental models in vivo and in vitro. HFpEF was induced in mice by feeding with HFD and L-NAME (0.5 g/L) in drinking water for 8 weeks, meanwhile the mice were treated with GE (25, 50 mg/kg) every other day. Cardiac echocardiography and exhaustive exercise were performed, blood pressure was measured at the end of treatment, and heart tissue specimens were collected after the mice were euthanized. We showed that GE administration significantly ameliorated cardiac oxidative stress, inflammation, apoptosis, fibrosis and metabolic disturbances in the hearts of HFpEF mice. We demonstrated that GE promoted the transcriptional activation of Nrf2 by targeting MMP2 to affect upstream SIRT1 and downstream GSK3β, which in turn alleviated the oxidative stress in the hearts of HFpEF mice. In H9c2 cells and HL-1 cells, we showed that treatment with GE (1 μM) significantly alleviated H2O2-induced oxidative stress through the MMP2/SIRT1/GSK3β pathway. In summary, GE regulates cardiac oxidative stress via MMP2/SIRT1/GSK3β pathway and reduces cardiac inflammation, apoptosis, fibrosis and metabolic disorders as well as cardiac dysfunction in HFpEF. GE exerts anti-oxidative stress properties by binding to MMP2, inhibiting ROS generation in HFpEF through the SIRT1/Nrf2 signaling pathway. In addition, GE can also affect the inhibition of the downstream MMP2 target GSK3β, thereby suppressing the inflammatory and apoptotic responses in HFpEF. Taken together, GE alleviates oxidative stress/apoptosis/fibrosis and metabolic disorders as well as HFpEF through the MMP2/SIRT1/GSK3β signaling pathway.

Exploration of the mechanism of Qinglongyi-Buguzhi drug pair in treating vitiligo based on network pharmacology, molecular docking and experimental verification. JOURNAL OF ETHNOPHARMACOLOGY 2024; 334:118595. [PMID: 39038503 DOI: 10.1016/j.jep.2024.118595] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/05/2024] [Revised: 06/14/2024] [Accepted: 07/17/2024] [Indexed: 07/24/2024]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The Qinglongyi-Buguzhi herbal pair (QB) is one of commonly used herbal combinations for treating vitiligo in traditional Chinese medicine, consisting of the exocarp of the immature fruit of Juglans regia L. or Juglans mandshurica Maxim., and dried, mature fruit of Psoralea corylifolia L. However, the active components and potential mechanisms of QB in the treatment of vitiligo are still unclear. AIM OF THE STUDY The purpose of this study is to clarify the effects and mechanisms of QB on vitiligo treatment through integration of network pharmacology and empirical examinations. MATERIALS AND METHODS The active components and targets of QB as well as the targets linked to vitiligo were obtained from network databases. Visualization networks were constructed with Cytoscape 3.9.1. GO and KEGG enrichment analysis were conducted to investigate the possible mechanism. Molecular docking was employed to evaluate the binding affinities between the primary active ingredients of QB and essential targets of the PI3K/Akt/Nrf2 pathway. In vivo and in vitro experiments were carried out to confirm the results of network pharmacology. RESULTS We evaluated 44 active compounds and 602 genes from QB, and 107 of these genes linked to vitiligo. GO analysis suggested QB might lessen vitiligo by regulating oxidative stress. KEGG pathway analysis indicated the PI3K/Akt pathway may be crucial for treating vitiligo. Molecular docking results demonstrated the key active ingredients of QB had good binding activity with the major targets in the PI3K/Akt/Nrf2 pathway. In vivo, QB significantly ameliorated vitiligo model mouse's skin pathologies by reducing ROS, elevating CAT and SOD levels. Western blot showed that QB increased the phosphorylation of PI3K and Akt and the expressions of Nrf2 and HO-1 in the skin. In vitro, QB reversed H2O2-induced oxidative injury of melanocytes, enhanced cell survival rate, reduced ROS level, upregulated SOD and CAT activities, and raised the content of melanin. Moreover, QB upregulated the expression levels of Akt, Nrf2, HO-1 mRNA, Akt phosphorylation, HO-1, and nuclear Nrf2 proteins, and also encouraged the nuclear translocation of Nrf2. However, LY294002 treatment significantly reversed the regulatory effect of QB on oxidative damage of melanocytes. CONCLUSIONS This study revealed that the therapeutic effect of QB on vitiligo was achieved through multiple components, targets and pathways. Experimental investigation demonstrated that QB could improve vitiligo via reducing oxidative stress, which was probably accomplished by activating the PI3K/Akt/Nrf2 signaling pathway.

Diabet Med 2024; 41:e15248. [PMID: 37876318 DOI: 10.1111/dme.15248] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/30/2023] [Revised: 10/11/2023] [Accepted: 10/16/2023] [Indexed: 10/26/2023]
Abstract
AIMS The objective of this study was to determine whether the use of glucagon-like peptide-1 receptor agonists (GLP-1 RAs) is associated with an increased risk of melanoma and nonmelanoma skin cancer, separately, compared with the use of sulfonylureas among patients with type 2 diabetes. METHODS Using the United Kingdom Clinical Practice Research Datalink (2007-2019), we assembled two new-user active comparator cohorts. In the first cohort assessing melanoma as the outcome, 11,786 new users of GLP-1 RAs were compared with 208,519 new users of sulfonylureas. In the second cohort assessing nonmelanoma skin cancer as the outcome, 11,774 new users of GLP-1 RAs were compared with 207,788 new users of sulfonylureas. Cox proportional hazards models weighted using propensity score fine stratification were fit to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) of melanoma and nonmelanoma skin cancer, respectively. RESULTS Compared with sulfonylureas, GLP-1 RAs were not associated with an increased risk of either melanoma (42.6 vs. 43.9 per 100,000 person-years, respectively; HR 0.96, 95% CI 0.53-1.75) or nonmelanoma skin cancer (243.9 vs. 229.9 per 100,000 person-years, respectively; HR 1.03, 95% CI 0.80-1.33). There was no evidence of an association between cumulative duration of use with either melanoma or nonmelanoma skin cancer. Consistent results were observed in secondary and sensitivity analyses. CONCLUSIONS In this population-based cohort study, GLP-1 RAs were not associated with an increased risk of melanoma or nonmelanoma skin cancer, compared with sulfonylureas.

A comprehensive review of ethnopharmacology, chemical constituents, pharmacological effects, pharmacokinetics, toxicology, and quality control of gardeniae fructus. JOURNAL OF ETHNOPHARMACOLOGY 2024; 320:117397. [PMID: 37956915 DOI: 10.1016/j.jep.2023.117397] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/12/2023] [Revised: 10/23/2023] [Accepted: 11/05/2023] [Indexed: 11/21/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Gardeniae Fructus (GF), the desiccative mature fruitage of Gardenia jasminoides J. Ellis (G. jasminoides), belongs to the Rubiaceae family. It has abundant medicinal value, such as purging fire and eliminating annoyance, clearing heat and diuresis, cooling blood, and detoxifying. GF is usually used in combination with other drugs to treat diseases such as fever and jaundice in damp heat syndrome in traditional Chinese medicines (TCMs) clinical practice. THE AIM OF THE REVIEW This review comprehensively summarizes the research progress in botany, traditional medical use, processing method, phytochemistry, pharmacological activity, quality control, pharmacokinetics, and toxicology, which aims to provide a scientific basis for the rational application and future research of GF. MATERIALS AND METHODS ScienceDirect, PubMed, Web of Science, China National Knowledge Infrastructure (CNKI), Embase, Scopus etc. databases were retrieved to gain the comprehensive information of GF. RESULTS At present, more than 215 compounds were isolated and identified from GF, including iridoids, diterpenes, triterpenoids, flavonoids, organic esters, and so on. The traditional application of GF mainly focused on clearing heat and detoxification. Pharmacological studies proved that GF had anti-inflammatory, antioxidation, antifatigue, antithrombotic, liver and gallbladder protection, and other pharmacological effects. In addition, many improved processing methods can alleviate the side effects and toxic reactions caused by long-term use of GF, so controlling its quality through multi-component content measurement has become an important means of research. CONCLUSION GF has a wide range of applications, the mechanisms by which some effective substances exert their pharmacological effects have not been clearly explained due to the complexity and diversity of its components. This review systematically elaborates on the traditional medical use, processing method, phytochemistry, pharmacological activity, quality control, and toxicology of GF, and it is expected to become a candidate drug for treating diseases, such as depression, pancreatitis, alcoholic or non-alcoholic fatty liver.

Abstract
The loss of epidermal melanocytes is a distinguishing feature of vitiligo (VIT), a prevalent and long-lasting skin ailment. While various hypotheses exist to explain the cause of VIT, the precise mechanisms leading to this disease remain unclear. Zinc finger MIZ-type containing 1 (ZMIZ1) has a strong link with the development and occurrence of VIT. However, the exact role of ZMIZ1 and its underlying mechanisms in VIT are not well understood. Our study aims to illustrate that targeting ZMIZ1 is an effective therapeutic and prophylactic strategy for treating VIT. We obtained the RNA expression profile of VIT samples using RNA-seq and determined the locations and expression of ZMIZ1 in these samples via immunochemistry. Glucose uptake was analyzed through immunofluorescence and glucose uptake assay. We evaluated mRNA levels using qPCR and used plasmids transfection to knock down ZMIZ1 in PIG1 and PIG3V cell lines. The activation of the mTOR/AKT/GSK-3β signalling pathway was assessed using Western blotting analysis. We found that ZMIZ1 expression was decreased in VIT samples. Decreased ZMIZ1 expression inhibits the proliferation, migration, and invasion of melanocytes in vitro. Moreover, we revealed that decreased ZMIZ1 could also inhibit the glucose uptake of melanocytes in vitro. Decreased ZMIZ1 expression inhibits the activation of the mTOR/AKT/GSK-3β pathway and the expression of melanin synthesis-related proteins in melanocytes. Finally, we demonstrated that decreased ZMIZ1 may inhibit the cell viability of melanocytes and the synthesis of melanin by mTOR/AKT/GSK-3β-mediated oxidative stress in vitro. In conclusion, our study suggests that decreased ZMIZ1 suppresses melanogenesis in vitiligo by regulating the mTOR/AKT/GSK-3β-mediated glucose uptake in vitro, making ZMIZ1 an attractive therapeutic target for the treatment of VIT.

PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2024; 123:155281. [PMID: 38103316 DOI: 10.1016/j.phymed.2023.155281] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/08/2023] [Revised: 11/22/2023] [Accepted: 12/11/2023] [Indexed: 12/19/2023]
Abstract
BACKGROUND Geniposide (GP) is an iridoid glycoside that is present in nearly 40 species, including Gardenia jasminoides Ellis. GP has been reported to exhibit neuroprotective effects in various Alzheimer's disease (AD) models; however, the effects of GP on AD models of Caenorhabditis elegans (C. elegans) and aging-accelerated mouse predisposition-8 (SAMP8) mice have not yet been evaluated. PURPOSE To determine whether GP improves the pathology of AD and sarcopenia. METHODS AD models of C. elegans and SAMP8 mice were employed and subjected to behavioral analyses. Further, RT-PCR, histological analysis, and western blot analyses were performed to assess the expression of genes and proteins related to AD and muscle atrophy. RESULTS GP treatment in the AD model of C. elegans significantly restored the observed deterioration in lifespan and motility. In SAMP8 mice, GP did not improve cognitive function deterioration by accelerated aging but ameliorated physical function deterioration. Furthermore, in differentiated C2C12 cells, GP ameliorated muscle atrophy induced by dexamethasone treatment and inhibited FoxO1 activity by activating AKT. CONCLUSION Although GP did not improve the AD pathology in SAMP8 mice, we suggest that GP has the potential to improve muscle deterioration caused by aging. This effect of GP may be attributed to the suppression of FoxO1 activity.

Investigation on the potential adverse outcome pathway of the sensitive endpoint for nephrotoxicity induced by gardenia yellow based on an integrated strategy using bioinformatics analysis and in vitro testing validation. Food Chem Toxicol 2023:113930.

Abstract
To explore the potential the adverse outcome pathway of Gardenia Yellow (GY)-induced sensitive endpoint for nephrotoxicity, an integrated strategy was applied in the present study. Using bioinformatic analysis, based on the constructed Protein-protein interaction networks, Gene Ontology function and Kyoto Encyclopedia of Genes and Genomes pathway enrichment analysis on the core target network were performed to illustrate the potential gene targets and signal pathways. Then, the most enriched pathway was validated with Cell counting kit-8 assays and Western blot analysis in embryonic kidney epithelial 293 cell models. According to the findings, GY may interact with 321 targets related to the endpoint. The five targets on the top ranking in the PPI network were STAT3, SRC, HRAS, AKT1, EP300. Among them, PI3K/Akt was the most enriched pathway. In vitro testing showed that GY exerted a proliferative effect on the cell variability in a dose-dependent manner. GY at concentration of 1000 μg/ml and stimulation for 30 min can significantly enhance the expression of phosphorylated Akt. Thus, after the quantitative weight of evidence evaluation, Akt phosphorylation induced PI3K/Akt activation was speculated as a molecular initiating event leading to a proliferative and inflammatory response in renal tubular epithelial cells.

Effective Therapeutic Verification of Crocin I, Geniposide, and Gardenia ( Gardenia jasminoides Ellis) on Type 2 Diabetes Mellitus In Vivo and In Vitro. Foods 2023; 12:foods12081668. [PMID: 37107463 PMCID: PMC10137615 DOI: 10.3390/foods12081668] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2023] [Revised: 04/10/2023] [Accepted: 04/14/2023] [Indexed: 04/29/2023] Open
Abstract
For many centuries, Gardenia (Gardenia jasminoides Ellis) was highly valued as a food homologous Chinese herbal medicine with various bioactive compounds, including crocin I and geniposide. However, the functional mechanism underlying the hypoglycemic effect of gardenia is absent in the literature. To evaluate the effect of gardenia and its different extracts on type 2 diabetes mellitus (T2DM) in in vivo and in vitro experiments, the dried gardenia powder was extracted using 60% ethanol and eluted at different ethanol concentrations to obtain the corresponding purified fragments. After that, the active chemical compositions of the different purified gardenia fragments were analyzed using HPLC. Then, the hypoglycemic effects of the different purified gardenia fragments were compared using in vitro and in vivo experiments. Finally, the different extracts were characterized using UPLC-ESI-QTOF-MS/MS and the mass spectrometric fragmentation pathway of the two main compounds, geniposide and crocin I, were identified. The experimental results indicated that the inhibitory effect of the 40% EGJ (crocin I) on the α-glucosidase was better than the 20% EGJ (geniposide) in vitro. However, the inhibitory effect of geniposide on T2DM was better than crocin I in the animal experiments. The different results in vivo and in vitro presumed potentially different mechanisms between crocin I and geniposide on T2DM. This research demonstrated that the mechanism of hypoglycemia in vivo from geniposide is not only one target of the α-glucosidase but provides the experimental background for crocin I and the geniposide deep processing and utilization.

Chang WL, Ko CH. The Role of Oxidative Stress in Vitiligo: An Update on Its Pathogenesis and Therapeutic Implications. Cells 2023; 12:cells12060936.

Abstract
Vitiligo is an autoimmune skin disorder caused by dysfunctional pigment-producing melanocytes which are attacked by immune cells. Oxidative stress is considered to play a crucial role in activating consequent autoimmune responses related to vitiligo. Melanin synthesis by melanocytes is the main intracellular stressor, producing reactive oxygen species (ROS). Under normal physiological conditions, the antioxidative nuclear factor erythroid 2-related factor 2 (Nrf2) pathway functions as a crucial mediator for cells to resist oxidative stress. In pathological situations, such as with antioxidant defects or under inflammation, ROS accumulate and cause cell damage. Herein, we summarize events at the cellular level under excessive ROS in vitiligo and highlight exposure to melanocyte-specific antigens that trigger immune responses. Such responses lead to functional impairment and the death of melanocytes, which sequentially increase melanocyte cytotoxicity through both innate and adaptive immunity. This report provides new perspectives and advances our understanding of interrelationships between oxidative stress and autoimmunity in the pathogenesis of vitiligo. We describe progress with targeted antioxidant therapy, with the aim of providing potential therapeutic approaches.

Abstract
Geniposide (GEN), a main compound extracted from Gardenia jasminoides fruit, has various biological activities including anti-inflammation, cellular damage alleviation, neuroprotection, and others. However, the effect of GEN on oxidative stress in hepatic cells is yet to be investigated. Our study uncovered that GEN eliminated excess intracellular free radicals by activating the Nrf2/ARE signaling pathway in H2O2-treated hepatocytes, while the protective effect was blocked by ML385 (an inhibitor of Nrf2). Moreover, H2O2 led to upregulation of miR-27b-3p in L02 cells, which was restrained by GEN. Overexpression of miR-27b-3p greatly weakened the antioxidant capacity of GEN in hepatocytes via directly targeting the Nrf2 gene. Our findings indicated that GEN treatment recovered H2O2-induced oxidative stress via targeting miR-27b-3p and thereby enhanced the antioxidant capacity by stimulating nuclear translocation and accumulation of Nrf2. These findings suggest that inhibition of miR-27b-3p to activate the Nrf2/ARE pathway by GEN is a potential alternative for hepatic oxidative damage alleviation.

DHPA Protects SH-SY5Y Cells from Oxidative Stress-Induced Apoptosis via Mitochondria Apoptosis and the Keap1/Nrf2/HO-1 Signaling Pathway. Antioxidants (Basel) 2022; 11:antiox11091794. [PMID: 36139869 PMCID: PMC9495558 DOI: 10.3390/antiox11091794] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/10/2022] [Revised: 09/03/2022] [Accepted: 09/09/2022] [Indexed: 11/18/2022] Open
Abstract
Oxidative stress in the brain is highly related to the pathogenesis of Alzheimer’s disease (AD). It could be induced by the overproduction of reactive oxygen species (ROS), produced by the amyloid beta (Aβ) peptide and excess copper (Cu) in senile plaques and cellular species, such as ascorbic acid (AA) and O2. In this study, the protective effect of 5-hydroxy-7-(4′-hydroxy-3′-methoxyphenyl)-1-phenyl-3-heptanone (DHPA) on Aβ(1–42)/Cu2+/AA mixture-treated SH-SY5Y cells was investigated via in vitro and in silico studies. The results showed that DHPA could inhibit Aβ/Cu2+/AA-induced SH-SY5Y apoptosis, OH· production, intracellular ROS accumulation, and malondialdehyde (MDA) production. Further research demonstrated that DHPA could decrease the ratio of Bax/Bcl-2 and repress the increase of mitochondrial membrane potential (MMP) of SH-SY5Y cells, to further suppress the activation of caspase-3, and inhibit cell apoptosis. Meanwhile, DHPA could inhibit the Aβ/Cu2+/AA-induced phosphorylation of Erk1/2 and P38 in SH-SY5Y cells, and increase the expression of P-AKT. Furthermore, DHPA could bind to Keap1 to promote the separation of Nrf2 to Keap1 and activate the Keap1/Nrf2/HO-1 signaling pathway to increase the expression of heme oxygenase-1 (HO-1), quinone oxidoreductase-1 (NQO1), glutathione (GSH), and superoxide dismutase (SOD). Thus, our results demonstrated that DHPA could inhibit Aβ/Cu2+/AA-induced SH-SY5Y apoptosis via scavenging OH·, inhibit mitochondria apoptosis, and activate the Keap1/Nrf2/HO-1 signaling pathway.

Abstract
White Spot Disease (WSD), caused by white spot syndrome virus (WSSV), is an acute and highly lethal viral disease of shrimp. Currently, there are no commercially available drugs to control WSD. It is urgent and necessary to find anti-WSSV drugs. Natural compounds are an important source of antiviral drug discovery. In this study, the anti-WSSV activity of natural compound geniposide (GP) was investigated in crayfish Procambarus clarkii. Results showed that GP had a concentration-dependent inhibitory effect on WSSV replication in crayfish at 24 h, and highest inhibition was more than 98%. In addition, GP significantly inhibited the expression of WSSV immediate-early gene ie1, early gene DNApol, late gene VP28. The mortality of WSSV-infected crayfish in control groups was 100%, while it reduced by 70.0% when treated with 50 mg/kg GP. Co-incubation, pre-treatment and post-treatment experiments showed that GP could prevent and treat WSSV infection in crayfish by significantly inhibiting WSSV multiplication. Mechanistically, the syntheses of WSSV structural proteins VP19, VP24, VP26 and VP28 were significantly inhibited by GP in S2 cells. Furthermore, GP could also suppress WSSV replication by blocking the expression of antiviral immunity-related factor STAT to reduce ie1 transcription. Moreover, GP possessed anti-inflammatory and anti-oxidative activity in crayfish. Overall, GP has the potential to be developed as a preventive or therapeutic agent against WSSV infection.

Abstract
Reactive oxygen species (ROS) produced in the ischemic myocardium can induce cardiomyocyte injury and death, resulting in cardiac remodeling. Ferroptosis, known as a newly type of cell death caused by iron-dependent oxidative stress, which is an essential death mechanism in cardiomyocytes. However, it is unclear whether oxidative stress products can further induce ferroptosis and aggravate cardiomyocyte injury. Geniposide (GEN), a major active component of Gardenia jasminoides J. Ellis, possesses the natural antioxidant activity and cardioprotective effect. Herein, we evaluated the role of ferroptosis in myocardial oxidative injury and the protective effect of GEN on myocardial ferroptosis. We first detected iron overload, massive ROS, and lipid peroxidation in ferric ammonium citrate (FAC)-treated cardiomyocytes, which were typical characteristics of ferroptosis. The iron overload-induced oxidative stress and ferroptosis aggravated cardiomyocyte injury, which were significantly alleviated by GEN treatment. Similar phenotypic changes of ferroptosis were consistently discovered in hydrogen peroxide (H2O2)-induced cells, which were reversed by GEN treatment as well. Interestingly, the RNA-binding protein Grsf1, which directly upregulated Gpx4 at the translational level, was activated by GEN following myocardial oxidative injury. The specific knockdown of Grsf1 increased their sensitivity to ferroptosis and weakened the cardioprotective effect of GEN in H2O2-treated cardiomyocytes. Moreover, GEN treatment reduced iron overload and lipid peroxidation in myocardial infarction (MI) rats, thereby fighting against the cardiac ischemic injury. Collectively, our study revealed the pathogenesis of oxidative stress and ferroptosis associated with myocardial ischemia, and indicated the antioxidant and anti-ferroptosis effects of GEN on preventing myocardial injury by activating the Grsf1/GPx4 axis, serving as a potential therapeutic target.

Abstract
BACKGROUND Oxidative stress and neurocyte apoptosis are crucial pathophysiological process in early brain injury (EBI) after subarachnoid hemorrhage (SAH). Geniposide (GNP) has been reported to exert neuroprotective effects by reducing oxidative injury and neurocyte apoptosis. However, the effect of GNP has not been clarified in EBI after SAH. The study was performed to evaluate the neuroprotective effects and mechanisms of GNP in EBI after SAH. METHODS AND RESULTS A total of 60 male Wistar rats were randomly divided into five groups. The prechiasmatic cistern SAH model was used in this study. SAH grade was evaluated using a grading system. Neurological function was evaluated using the Garcia scores. Brain edema was measured by the wet-dry method. Blood-brain barrier (BBB) permeability was measured by the extravasation of Evans Blue (EB). The neurocyte apoptosis was observed using TUNEL assay. The levels of malondialdehyde (MDA) and superoxide dismutase (SOD), as well as the expressions of nuclear factor erythroid 2-related factor 2 (Nrf2), hemeoxygenase-1 (HO-1), glutathione S-transferase (GST) and quinone oxidoreductase-1 (NQO-1) were performed. The results showed that GNP reduced brain edema, attenuated BBB permeability, inhibited neurocyte apoptosis and improved neurological function. Moreover, GNP also decreased the levels of ROS and MDA, elevated Nrf2 expression in the temporal cortex and up-regulated the expression of NQO-1, HO-1 and GST after SAH. CONCLUSIONS GNP could ameliorate oxidative stress and neurocyte apoptosis to exert neuroprotective effects by Nrf2 pathway.

Abstract
Vitiligo is a common acquired depigmenting disease characterized by the loss of functional melanocytes and epidermal melanin. Vitiligo has a long treatment cycle and slow results, which is one of the most difficult challenges for skin diseases. Oxidative stress plays an important role as an initiating and driving factor in the pathogenesis of vitiligo. Antioxidant therapy has recently become a research hotspot in vitiligo treatment. A series of antioxidants has been discovered and applied to the treatment of vitiligo, which has returned satisfactory results. This article briefly reviews the relationship between oxidative stress and vitiligo. We also describe the progress of targeted antioxidant therapy in vitiligo, with the aim of providing a reference for new drug development and treatment options for this condition.

Abstract
Vitiligo is the most common depigmenting disorder characterized by white patches in the skin. The pathogenetic origin of vitiligo revolves around autoimmune destruction of melanocytes in which, for instance, oxidative stress is responsible for melanocyte molecular, organelle dysfunction and melanocyte specific antigen exposure as well as melanocyte cell death and thus serves as an important contributor for vitiligo progression. In recent years, natural products have shown a wide range of pharmacological bioactivities against many skin diseases, and this review focuses on the effects and mechanisms of natural compounds against vitiligo models. It is showed that some natural compounds such as flavonoids, phenols, glycosides and coumarins have a protective role in melanocytes and thereby arrest the depigmentation, and, additionally, Nrf2/HO-1, MAPK, JAK/STAT, cAMP/PKA, and Wnt/β-catenin signaling pathways were reported to be implicated in these protective effects. This review discusses the great potential of plant derived natural products as anti-vitiligo agents, as well as the future directions to explore.

Abstract
Glucagon-like peptide-1 (GLP-1) receptor-based therapies have been developed and extensively applied in clinical practice. GLP-1 plays an important role in improving glycemic homeostasis by stimulating insulin biosynthesis and secretion, suppressing glucagon activity, delaying gastric emptying, and reducing appetite and food ingestion. Furthermore, GLP-1 has positive effects on β-cell function by promoting β-cell proliferation and neogenesis while simultaneously reducing apoptosis. Here, we summarize possible mechanisms of action of GLP-1 upon pancreatic islets as well as describe phytochemicals that modulate pancreatic islet β cell function through glucagon-like peptide-1-related mechanisms. Together, this information provides potential lead compound candidates against diabetes that function as GLP-1 receptor-based pharmacotherapy.

Abstract
Vitiligo is a cutaneous depigmentation disorder caused by melanocyte injury or aberrant functioning. Oxidative stress (OS) is considered to be a major cause of the onset and progression of vitiligo. Ginsenoside Rk1 (RK1), a major compound isolated from ginseng, has antioxidant activity. However, whether RK1 can protect melanocytes against oxidative injury remains unknown. The aim of the present study was to investigate the potential protective effect of RK1 against OS in the human PIG1 melanocyte cell line induced with hydrogen peroxide (H2O2), and to explore its underlying mechanism. PIG1 cells were pretreated with RK1 (0, 0.1, 0.2 and 0.4 mM) for 2 h followed by exposure to 1.0 mM H2O2 for 24 h. Cell viability and apoptosis were determined with Cell Counting Kit‑8 and flow cytometry assays, respectively. The activity levels of superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GSH‑Px) were analyzed using ELISA kits. Protein expression levels, including Bax, caspase‑3, Bcl‑2, phosphorylated‑AKT, AKT, nuclear factor erythroid 2‑related factor 2 (Nrf2), heme oxygenase‑1 (HO‑1), cytosolic Nrf2 and nuclear Nrf2, were analyzed using western blot analysis. In addition, the expression and localization of Nrf2 were detected by immunofluorescence. RK1 treatment significantly improved cell viability, reduced the apoptotic rate and increased the activity levels of SOD, CAT and GSH‑Px in the PIG1 cell line exposed to H2O2. In addition, RK1 treatment notably induced Nrf2 nuclear translocation, increased the protein expression levels of Nrf2 and HO‑1, and the ratio of phosphorylated‑AKT to AKT in the PIG1 cells exposed to H2O2. Furthermore, LY294002 could reverse the protective effect of RK1 in melanocytes against oxidative injury. These data demonstrated that RK1 protected melanocytes from H2O2‑induced OS by regulating Nrf2/HO‑1 protein expression, which may provide evidence for the application of RK1 for the treatment of vitiligo.

The phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt) signaling pathway regulates cell proliferation, differentiation, and migration, along with angiogenesis and metabolism. Additionally, it could mediate skin development and homeostasis. There is much evidence to suggest that dysregulation of PI3K/Akt pathway is frequently associated with several human cutaneous malignancies like malignant melanoma (MM), basal cell carcinoma (BCC), and cutaneous squamous cell carcinoma (SCC), as well as their poor outcomes. Nevertheless, emerging roles of PI3K/Akt pathway cascade in a group of common non-malignant skin disorders including acne and psoriasis, among others, have been recognized. The enhanced understanding of dysfunction of PI3K/Akt pathway in patients with these non-malignant disorders has offered a solid foundation for the progress of updated therapeutic targets. This article reviews the latest advances in the roles of PI3K/Akt pathway and their targets in the skin homeostasis and progression of a wide range of non-malignant skin disorders and describes the current progress in preclinical and clinical researches on the involvement of PI3K/Akt pathway targeted therapies.

Abstract
Sunlight contains a significant amount of ultraviolet (UV) ray, which leads to various effects on homeostasis in the body. Defense strategies to protect from UV rays have been extensively studied, as sunburn, photoaging, and photocarcinogenesis are caused by excessive UV exposure. The primary lines of defense against UV damage are melanin and trans-urocanic acid, which are distributed in the stratum corneum. UV rays that pass beyond these lines of defense can lead to oxidative damage. However, cells detect changes due to UV rays as early as possible and initiate cell signaling processes to prevent the occurrence of damage and repair the already occurred damage. Cosmetic and dermatology experts recommend using a sunscreen product to prevent UV-induced damage. A variety of strategies using antioxidants and anti-inflammatory agents have also been developed to complement the skin's defenses against UV rays. Researchers have examined the use of plant-derived materials to alleviate the occurrence of skin aging, diseases, and cancer caused by UV rays. Furthermore, studies are also underway to determine how to promote melanin production to protect from UV-induced skin damage. This review provides discussion of the damage that occurs in the skin due to UV light and describes potential defense strategies using plant-derived materials. This review aims to assist researchers in understanding the current research in this area and to potentially plan future studies.

Abstract
Uncontrolled inflammatory response and subsequent cardiomyocytes loss (apoptosis and pyroptosis) are closely involved in sepsis-induced myocardial dysfunction. Our previous study has found that geniposide (GE) can protect the murine hearts against obesity-induced inflammation. However, the effect of GE on sepsis-related cardiac dysfunction is still unknown. Mice were exposed to lipopolysaccharide (LPS) to generate sepsis-induced myocardial dysfunction. And 50 mg/kg GE was used to treat mice for consecutive 7 days. Our results showed that GE treatment significantly improved survival rate and cardiac function, and suppressed myocardial inflammatory response, as well as myocardial loss in LPS-treated mice. Those effects of GE were largely abolished in NOD-like receptor protein 3 (NLRP3)-deficient mice. Further detection revealed that the inhibition of NLRP3 inflammasome activation depended on the reduction of p47phox by GE. GE treatment restored the phosphorylation and activity of AMP-activated protein kinase α (AMPKα) in the hearts of sepsis mice, and knockout of AMPKα abolished the protection of GE against reactive oxygen species (ROS) accumulation, NLRP3 inflammasome activation and cardiomyocytes loss in sepsis mice. In conclusion, our findings revealed that GE activated AMPKα to suppress myocardial ROS accumulation, thus blocking NLRP3 inflammasome-mediated cardiomyocyte apoptosis and pyroptosis and improving cardiac function in mice with sepsis.

Int J Mol Med 2020; 45:1305-1316. [PMID: 32323738 PMCID: PMC7138279 DOI: 10.3892/ijmm.2020.4520] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/02/2019] [Accepted: 11/21/2019] [Indexed: 12/22/2022] Open
Abstract
Oxidized low‑density lipoprotein (ox‑LDL)‑induced vascular endothelial damage, oxidative stress and inflammation play a vital role in the pathophysiology of atherosclerosis. Geniposide is the primary active ingredient from Gardenia jasminoides Ellis associated with anti‑oxidative properties and cardioprotective action. However, the therapeutic mechanism of geniposide in atherosclerosis remains unclear. Hence, the present study aimed to elucidate the underlying mechanisms of geniposide in oxidative stress and inflammatory response during ox‑LDL injury in human umbilical vein endothelial cells (HUVECs), focusing particularly on the microRNA (miR)‑21/PTEN pathway. The results demonstrated that geniposide pretreatment significantly increased cell viability, decreased lactate dehydrogenase release, increased miR‑21 level and decreased PTEN expression under ox‑LDL condition. Subsequently, transfection with miR‑21 mimic enhanced the protection of geniposide on ox‑LDL‑induced cytotoxicity and apoptosis (mediated by the upregulation of apoptotic rate and caspase‑3 activity), whereas miR‑21 inhibitor reversed these effects of geniposide. In addition, geniposide resulted in an anti‑oxidant effect as evidenced by the decrease in reactive oxygen species generation, malondialdehyde content and NADPH oxidase 2 expression, and the increase in superoxide dismutase, glutathione peroxidase and catalase activities in ox‑LDL‑treated HUVECs, which were exacerbated by miR‑21 mimic and reversed by miR‑21 inhibitor. Furthermore, geniposide mitigated the ox‑LDL‑induced inflammatory response, demonstrated by a downregulation of pro‑inflammatory cytokine (IL‑1β, IL‑6, and TNF‑α) levels and an upregulation of anti‑inflammatory cytokine (IL‑10) level. However, miR‑21 mimic enhanced, whereas miR‑21 inhibitor attenuated, these effects of geniposide. In conclusion, the present results indicated that geniposide protects HUVECs from ox‑LDL injury by inhibiting oxidative stress and inflammation, and that these effects are partly due to the enhancement of the miR‑21/PTEN pathway.

Abstract
OBJECTIVE To assess geniposide's effects in New Zealand rabbits with high-fat diet induced atherosclerosis and to explore the underpinning mechanisms. MATERIALS AND METHODS Aorta histological changes were evaluated by intravenous ultrasound (IVUS) and H&E staining. Lipid accumulation in the aortic was quantified by Oil Red O staining. Then, RNA sequencing (RNA-seq) was carried out for detecting differentially expressed genes in rabbit high-fat diet induced atherosclerosis. The levels of the cytokines CRP, IL-1β and IL-10 were determined by ELISA. Protein levels of iNOS and Arg-1 were assessed by Western blot and immunohistochemical staining. The mRNA expression levels of NR4A1, CD14, FOS, IL1A, iNOS and Arg-1 were detected by quantitative real-time PCR (qPCR). RESULTS Geniposide markedly reduced the degree of atherosclerotic lesions in aorta tissues. RNA-seq and qPCR demonstrated that NR4A1, CD14, FOS and IL1A mRNA amounts were overtly increased in New Zealand rabbits with high-fat diet induced atherosclerosis. Moreover, geniposide reduced iNOS (M1 phenotype) mRNA and protein amounts as well as IL-1β secretion, which were enhanced in New Zealand rabbits with high-fat diet induced atherosclerosis. Besides, Arg-1 (M2 phenotype) mRNA and protein amounts were significantly increased after geniposide treatment, as well as IL-10 secretion. CONCLUSION These findings suggest that geniposide could inhibit the progression of and stabilize atherosclerotic plaques in rabbits by suppressing M1 macrophage polarization and promoting M2 polarization through the FOS/MAPK signaling pathway.

Abstract
The research plans to make sure how Geniposide (GEN) functions in osteoblast proliferation and differentiation. The MC3T3-E1 and ATDC5 cells were treated with the GEN, XAV-939 and/or transfected with microRNA (miR)-214 mimic or corresponding control. Cell viability was detected with the CCK-8. The CyclinD1, Runx2, Osx, Ocn, Wnt3a and β-catenin were individually quantified via western blot. The cell cycle was tested by cell cycle analysis assay. The ALP activity was tested by ALP assay. qRT-PCR was used to examine the miR-214 expression level. The cell viability and the expressions of the CyclinD1, Runx2, Osx, Ocn Wnt3a and β-catenin, as well as the ALP activity were individually and significantly promoted by the GEN. Besides, miR-214 was down-regulated by the GEN. The XAV-939 or the miR-214 mimic destroyed the promotional effect of GEN on these elements above. In conclusion, GEN induced the proliferation and differentiation of the MC3T3-E1 and ATDC5 cells by targeting the miR-214 through Wnt/β-catenin activation.

Abstract
Geniposide is an active ingredient with anti-apoptotic and anti-inflammatory properties. This study was to examine the effects of geniposide on a cell model of spinal cord injury (SCI). PC12 cells were administrated with geniposide before subjected to LPS. The effects of geniposide were analyzed by utilizing CCK-8 assay, apoptosis assay, ELISA, RT-qPCR and Western blot. We found that PC12 cells viability was unchanged by treating with geniposide. However, geniposide with concentrations of 200 or 300 μg/mL significantly mitigated LPS-evoked viability loss. Meanwhile, apoptosis driven by LPS was mitigated by geniposide, which accompanied with p53, Bax and cleaved caspase-3 down-regulation, and Bcl-2 up-regulation. Besides this, the expression and release of IL-1β, IL-6, IL-8 and TNF-α evoked by LPS were mitigated by geniposide. miR-145-5p was a target of geniposide. miR-145-5p expression was up-regulated by geniposide, and geniposide did not protect PC12 cells against LPS injury when miR-145-5p was silenced. Moreover, geniposide inhibited NF-κB and JNK pathways via up-regulating miR-145-5p. In short, the present work described the neuroprotective effects of geniposide by targeting miR-145-5p. Further mechanisms involved in geniposide's beneficial effects are correlated with the inhibited NF-κB and JNK pathways. Highlights Geniposide prevents LPS-induced injury in PC12 cells; Geniposide up-regulates miR-145-5p; Geniposide protects PC12 cells via up-regulation of miR-145-5p; Geniposide inhibits NF-κB and JNK pathways via up-regulation of miR-145-5p.

Abstract
BACKGROUND/AIMS Liver cancer is distinguished as an irredeemable disease. We detected the geniposide (GEN) in HepG2 and Huh7 cell lines. METHODS HepG2 and Huh7 cells were individually induced with GEN dilutions, and then they were transfected with microRNA (miR)-224 overproduction vector (miR-224 mimic) as well as the corresponding negative control (NC). Cell viability was detected with the CCK-8. The apoptotic rate was determined by the Annexin V-FITC/PI with flow cytometer. The migration or invasion rates were separately determined by migration assay or millicell hanging cell culture. The expression of miR-224 was quantified depending on qRT-PCR. Relative proteins were individually determined via western blot. RESULTS GEN treatment induced inhibition of HepG2 and Huh7 cells proliferation, migration and invasion but promotion of apoptosis. miR-224 was down-regulated by GEN. Transfection of miR-224 mimic led to high expression of miR-224, which partly rescued cancer cells survival by prohibiting cell apoptosis. Moreover, the production of Wnt/β-catenin and AKT proteins was notably reduced by GEN but increased by overexpressed miR-224. CONCLUSION GEN played anti-tumor roles by targeting miR-224 via blocking the Wnt/β-catenin and AKT cascades in the HepG2 and Huh7 cells.

Abstract
We aimed to investigate whether geniposide, a main component extracted from Gardenia jasminoides Ellis fruit, could exert neuroprotective functions against traumatic brain injury (TBI). Enzyme-linked immunosorbent assay (ELISA) was used for detection of plasma cytokines. Real-time polymerase chain reaction (RT-PCR) was employed for measurements of mRNA levels of cytokines. Neurological outcomes were evaluated by modified neurological severity score (mNSS) and Rota-Rod. Blood-brain barrier (BBB) integrity and brain edema were assessed. Protein expression was tested by Western blot. The plasma levels of interleukin (IL)-1β, IL-6, IL-8 and IL-10 were all elevated in patients with TBI compared to those of healthy controls. TBI rats treated with geniposide showed lower mNSS and longer fall latency time than untreated TBI rats. BBB integrity was maintained and brain edema was reduced by geniposide treatment in TBI rats. Plasma levels of IL-1β, IL-6 and IL-8 were significantly repressed by geniposide treatment in TBI rats, whereas IL-10 level was upregulated. mRNA expression levels of these cytokines in the brain tissues of TBI rats exhibited the same trends of changes. By testing p38 mitogen-activated protein kinase and NF-κB p65 activities, it was observed that phosphorylated (p)-p38 and p-p65 were dramatically inhibited by geniposide. In conclusion, geniposide exerts neuroprotective functions against TBI by inhibiting p-p38 and p-p65.

Abstract
Geniposide, the main medicinal ingredient of Gardenia jasminoides Ellis, is known to be a resistant agent to atherosclerosis. Some reports its mechanism against atherosclerosis remains completely unclear. Herein, we have investigated the protective effect of geniposide against atherosclerosis as well as clarified the mechanisms related with inhibiting the formation of foam cells and lowering reverse lipid transport via p38/MAPK signaling pathways. Macrophage Raw264.7 was induced by lysophosphatidic acid (LPA) to form foam cell as a cell model. ApoE-/- mice were fed with a high-fat diet for 16 weeks to cause atherosclerosis in carotid artery. After treatment with geniposide, CCK-8, oil red O stain, qRT-PCR and western blot were carried out to explore the effect of geniposide. Morphological changes, histological analyses were used to evaluate atherosclerosis in ApoE-/- mice. Geniposide significantly reduced serum total cholesterol (TC), triglyceride (TG) and LDL cholesterol levels in ApoE-/- mice compared with vehicle control. Meanwhile, geniposide dose dependently inhibited the development of atherosclerosis in ApoE-/- mice. Furthermore, geniposide observably inhibited the formation of foam cells induced by LPA, down-regulated the mRNA and protein levels of SR-A and up-regulated the mRNA and protein levels of ABCA1 or SR-B1 in vitro via inhibition of the p38MAPK and AKT signaling pathways. Our study shows that geniposide protected against atherosclerosis and inhibited the formation of foam cells by regulating the equilibrium on expression of diverse lipid transporters in cytomembrane which related with p38MAPK and AKT signaling pathways. Geniposide is a potential therapeutic drug for atherosclerosis.

[PMID: 31485649 PMCID: PMC6755204 DOI: 10.3892/mmr.2019.10607] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2019] [Accepted: 07/11/2019] [Indexed: 01/07/2023] Open
Abstract
It has been reported that loss and degradation of epidermal melanocytes is closely associated with the pathogenesis of vitiligo. In addition, CD8+ T and regulatory T (Treg) cells serve an important role during these two processes. MicroRNA-155 (miR-155) is known to contribute to the pathogenesis of vitiligo; however, the mechanism by which miR-155 regulates the development of vitiligo remains unclear. In the present study, naïve T and CD8+ T cells were isolated from a patient with non-segmental vitiligo by flow cytometry. The cells were differentiated into Treg cells by treatment with interleukin-2, transforming growth factor-β and retinoic acid. In addition, miR-155 agonists and antagonists were used to investigate the effect of miR-155 on the proliferation of CD8+ T cells, Treg cells and melanocytes. The results demonstrated that the miR-155 agonist significantly decreased the rate of CD8+ T cell growth, as well as promoted the proliferation of melanocytes by inducing an increase in the percentage of Treg cells. By contrast, the miR-155 antagonist inhibited the proliferation of melanocytes by decreasing the percentage of Treg cells. miR-155 protected melanocyte survival by increasing the number of Treg cells and by decreasing the number of CD8+ T cells. Therefore, these data may provide a new prospect for the treatment of vitiligo.

Front Pharmacol 2019; 10:411. [PMID: 31057410 PMCID: PMC6482204 DOI: 10.3389/fphar.2019.00411] [Citation(s) in RCA: 21] [Impact Index Per Article: 4.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2018] [Accepted: 04/01/2019] [Indexed: 12/12/2022] Open
Abstract
Glucocorticoid (GC) therapy is the leading cause of secondary osteoporosis and the therapeutic and preventative drugs for GC-induced osteoporosis are limited. In this study, we investigated the protective effects of geniposide on dexamethasone (DEX)-induced osteogenic inhibition in MC3T3-E1 cells. The results showed that there was no obvious toxicity on MC3T3-E1 cells when geniposide was used at the doses ranging from 1 to 75 μM. In DEX-treated MC3T3-E1 cells, geniposide promoted the alkaline phosphatase (ALP) activity and the mineralization. In addition, geniposide also significantly increased the mRNA and protein expression of osteopontin (OPN), Runt-related transcription factor 2 (Runx2), and Osterix (Osx) in DEX-treated MC3T3-E1 cells. Furthermore, geniposide activated ERK pathway in DEX-treated MC3T3-E1 cells. The ERK activation inhibitor U0126 and glucagon-like peptide-1 (GLP-1) receptor antagonist exendin 9-39 abolished the geniposide-induced activation of ERK and inhibited the protective effect of geniposide. Taken together, our study revealed that geniposide alleviated GC-induced osteogenic suppression in MC3T3-E1 cells. The effect of geniposide was at least partially associated with activating ERK signaling pathway via GLP-1 receptor. Geniposide might be a potential therapeutic agent for GC-induced osteoporosis.
