[PMID: 38658922 PMCID: PMC11041011 DOI: 10.1186/s12974-024-03105-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2023] [Accepted: 04/18/2024] [Indexed: 04/26/2024] Open
Abstract
BACKGROUND Intracerebral hemorrhage (ICH) is a devastating neurological disease causing severe sensorimotor dysfunction and cognitive decline, yet there is no effective treatment strategy to alleviate outcomes of these patients. The Mas axis-mediated neuroprotection is involved in the pathology of various neurological diseases, however, the role of the Mas receptor in the setting of ICH remains to be elucidated. METHODS C57BL/6 mice were used to establish the ICH model by injection of collagenase into mice striatum. The Mas receptor agonist AVE0991 was administered intranasally (0.9 mg/kg) after ICH. Using a combination of behavioral tests, Western blots, immunofluorescence staining, hematoma volume, brain edema, quantitative-PCR, TUNEL staining, Fluoro-Jade C staining, Nissl staining, and pharmacological methods, we examined the impact of intranasal application of AVE0991 on hematoma absorption and neurological outcomes following ICH and investigated the underlying mechanism. RESULTS Mas receptor was found to be significantly expressed in activated microglia/macrophages, and the peak expression of Mas receptor in microglia/macrophages was observed at approximately 3-5 days, followed by a subsequent decline. Activation of Mas by AVE0991 post-treatment promoted hematoma absorption, reduced brain edema, and improved both short- and long-term neurological functions in ICH mice. Moreover, AVE0991 treatment effectively attenuated neuronal apoptosis, inhibited neutrophil infiltration, and reduced the release of inflammatory cytokines in perihematomal areas after ICH. Mechanistically, AVE0991 post-treatment significantly promoted the transformation of microglia/macrophages towards an anti-inflammatory, phagocytic, and reparative phenotype, and this functional phenotypic transition of microglia/macrophages by Mas activation was abolished by both Mas inhibitor A779 and Nrf2 inhibitor ML385. Furthermore, hematoma clearance and neuroprotective effects of AVE0991 treatment were reversed after microglia depletion in ICH. CONCLUSIONS Mas activation can promote hematoma absorption, ameliorate neurological deficits, alleviate neuron apoptosis, reduced neuroinflammation, and regulate the function and phenotype of microglia/macrophages via Akt/Nrf2 signaling pathway after ICH. Thus, intranasal application of Mas agonist ACE0991 may provide promising strategy for clinical treatment of ICH patients.

Untargeted metabolomics reveals the regulatory effect of geniposidic acid on lipid accumulation in HepG2 cells and Caenorhabditis elegans and validation in hyperlipidemic hamsters. PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2024; 125:155295. [PMID: 38277945 DOI: 10.1016/j.phymed.2023.155295] [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: 05/26/2023] [Revised: 12/08/2023] [Accepted: 12/16/2023] [Indexed: 01/28/2024]
Abstract
BACKGROUND Geniposidic acid (GPA) alleviates oxidative stress and inflammation in mice However, whether it can effectively regulate lipid accumulation and prevent hyperlipidemia requires further investigation. PURPOSE This study combined the untargeted metabolomics of cells and a Caenorhabditis elegans model to evaluate the anti-hyperlipidemic potential of GPA by modulating oxidative stress and regulating lipid metabolism. A golden hamster model of hyperlipidemia was used to further validate the lipid-lowering effect and mechanism of action of GPA. METHODS Chemical staining, immunofluorescence, and flow cytometry were performed to examine the effects of GPA on lipid accumulation and oxidative stress. Untargeted metabolomic analysis of cells and C. elegans was performed using ultra-performance liquid chromatography coupled with quadrupole electrostatic field Orbitrap high-resolution mass spectrometry (UPLC-Q-Orbitrap MS) to identify biomarkers altered by GPA action, analyze the affected metabolic pathways, and validate the mechanisms by which GPA regulates lipid metabolism and oxidative stress. A golden hamster model of hyperlipidemia was established to test the lipid-lowering effects of GPA. Body weight, biochemical markers, rate-limiting enzymes, and key proteins were assessed. Hematoxylin and eosin (H&E) and Oil Red O staining were performed. RESULTS Phenotypic data showed that GPA decreased free fatty acid (FFA)-induced lipid buildup and high reactive oxygen species (ROS) levels, reversed the decrease in mitochondrial membrane potential (MMP), and increased the cellular reduced glutathione/oxidized glutathione disulfide (GSH/GSSG) ratio. GPA also reduces high glucose-induced lipid build-up and ROS production in C. elegans. Metabolomic analysis showed that GPA affected purine, lipid, and amino acid metabolism. Moreover, GPA inhibited xanthine oxidase (XOD), glutamate dehydrogenase (GLDH), fatty acid synthase (FAS), phosphorylation of P38 MAPK, and upregulated the expression of SIRT3 and CPT1A protein production to control lipid metabolism and produce antioxidant benefits in cells and golden hamsters. CONCLUSION Current evidence suggests that GPA can effectively regulate lipid metabolism and the oxidative stress response, and has the potential to prevent hyperlipidemia. This study also provided an effective method for evaluating the mechanism of action of GPA.

Study on the substance basis of the efficacy of eucommiae cortex before and after salt processing for the treatment of kidney-yang deficiency syndrome based on the spectrum-effect relationship. JOURNAL OF ETHNOPHARMACOLOGY 2024; 318:116926. [PMID: 37479066 DOI: 10.1016/j.jep.2023.116926] [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: 04/24/2023] [Revised: 07/13/2023] [Accepted: 07/14/2023] [Indexed: 07/23/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Kidney-Yang deficiency syndrome (KYDS) is one of the common diseases of the elderly and closely related to the ageing of the body, it has a major impact on the quality of life of the patient. Eucommiae Cortex (EC) is the dried bark of Eucommia ulmoides Oliv. Which has the effect of tonifying the liver and kidneys, strengthening the muscles and bones. In Traditional Chinese Medicine clinics, EC is commonly used in the treatment of KYDS, but the material basis for the improvement of its efficacy in treating KYDS after salt processing remains unclear. AIM OF THE STUDY This study aimed to find the main active ingredients that could improve the treatment of KYDS efficacy of EC after salt processing. MATERIALS AND METHODS Firstly, the fingerprints of raw and salt-processed EC were established to determine the common components by using HPLC, and then an experimental study on the treatment of KYDS efficacy was carried out to compare the difference in the efficacy between raw and salt-processed EC. Thirdly, the spectrum-effect relationship of chemical components and pharmacodynamic indexes was established by using Grey Relational Analysis and Entropy Method. Finally, the network pharmacology and molecular docking technique was used to verify the kidney tonifying effect of the active ingredients of EC. RESULTS According to the results of the analysis of hormonal index levels on the hypothalamic-pituitary-target gland axis and the extent of renal lesions, the therapeutic effect of EC on KYDS was mainly reflected in the regulation of the Adrenocorticotropic hormone, Corticosterone in the hypothalamic-pituitary-adrenal axis and Tri-iodothyronine, Tetra-iodothyronine in the hypothalamic-pituitary-thyroid axis, moreover the therapeutic effect of salt-processed EC was stronger than that of raw EC. The pharmacologically active ingredients that improved its treatment of KYDS efficacy after salt processing were peak 1 (geniposidic acid), peak 2 (chlorogenic acid), peak 5 (geniposide), peak 6 (genipin), peak 7 (pinoresinol diglucoside) and peak 11 (hyperoside). Meanwhile, the results of network pharmacology and molecular docking showed that the 6 active ingredients could exert kidney tonic effects through multiple signaling pathways by acting on core targets such as AKT1 and PTGS2. CONCLUSION As far as we known, this was the first time to establish and compare the spectrum-effect relationship between raw and salt-processed EC, which laid the foundation for the pharmacokinetics studies of EC and provided a reference for future EC studies.
