JOURNAL OF ETHNOPHARMACOLOGY 2024; 337:118763. [PMID: 39216773 DOI: 10.1016/j.jep.2024.118763] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/03/2024] [Revised: 08/14/2024] [Accepted: 08/28/2024] [Indexed: 09/04/2024]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE At present,the global form of hypertension is severe,and liver-yang-hyperactivity hypertension(GYSK hypertension)is the most common type of hypertension.Folium Polygoni Cuspidati(HZY)are mainly used in Yunnan, China,to treat dizziness, headache,and hypertension caused by GYSK,and the content of the active ingredients of HZY and its efficacy varies in different periods.However,the mechanism of action and the effect of harvesting period are not clear. AIM OF THE STUDY The purpose of this research was to investigate the effect of HZY in April and September on GYSK hypertension. MATERIALS AND METHODS The model of GYSK hypertension was established with aconite decoction and L-NAME,and the blood pressure,the symptoms of GYSK,the cardiac index and the pathological changes of aorta were observed,to study the effect of HZY in April and September on GYSK hypertension.The chemical composition of HZY was analysed by UPLC-QTOF-MS and its mechanism for the treatment of GYSK hypertension was predicted by network pharmacological studies and experimentally validated using serum metabolomics and Western blot techniques. RESULTS April HZY and September HZY can significantly improve the GYSK symptoms of rats, inhibit the RAAS system, improve oxidative stress and regulate blood lipids so as to play a blood pressure lowering efficacy and have a protective effect on the vascular endothelial cells.UPLC-QTOF-MS yielded 29 components of HZY,and network pharmacology predicted that its mechanism may be related to Lipid and atherosclerosis,PI3K/Akt signaling pathway, MAPK signaling pathway and TNF signaling pathway,etc.Western Blot validation showed that HZY activated PI3K,p-Akt protein expression and inhibited p-erk,p-p38 and TNF-α protein expression.Serum metabolomics suggested that April HZY exerts its efficacy mainly by regulating amino acid metabolism and September HZY mainly by regulating lipid metabolism. CONCLUSIONS In GYSK hypertensive rats treated for three weeks, both April HZY and September HZY could have antihypertensive effects,but the mechanisms of action were different and similar, both could regulate metabolite disorders of sugars, lipids,amino acids and peptides,and regulate blood pressure through the PI3K/Akt-eNOS and MAPK signalling pathways, with the difference that April HZY had stronger regulatory effects on the metabolism of amino acids.metabolism.

[PMID: 36809697 DOI: 10.1016/j.compbiomed.2023.106660] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2022] [Revised: 02/04/2023] [Accepted: 02/09/2023] [Indexed: 02/12/2023]
Abstract
A diabetic ulcer (DU) is a dreaded and resistant complication of diabetes mellitus with high morbidity. Fu-Huang ointment (FH ointment) is a proven recipe for treating chronic refractory wounds; however, its molecular mechanisms of action are unclear. In this study, we identified 154 bioactive ingredients and their 1127 target genes in FH ointment through the public database. The intersection of these target genes with 151 disease-related targets in DUs resulted in 64 overlapping genes. Overlapping genes were identified in the PPI network and enrichment analyses. The PPI network identified 12 core target genes, whereas Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis indicated that upregulation of the PI3K/Akt signalling pathway was involved in the role of FH ointment in treating diabetic wounds. Molecular docking showed that 22 active compounds in FH ointment could enter the active pocket of PIK3CA. Molecular dynamics was used to prove the binding stability of the active ingredients and protein targets. We found that PIK3CA/Isobutyryl shikonin and PIK3CA/Isovaleryl shikonin combinations had strong binding energies. An in vivo experiment was conducted on PIK3CA, which was the most significant gene.This study comprehensively elucidated the active compounds, potential targets, and molecular mechanism of FH ointment application in treating DUs, and believed that PIK3CA is a promising target for accelerated healing.

Abstract
Pre-stroke exercise conditioning reduces neurovascular injury and improves functional outcomes after stroke. The goal of this study was to explore if post-stroke exercise conditioning (PostE) reduced brain injury and whether it was associated with the regulation of gluconeogenesis. Adult rats received 2 h of middle cerebral artery (MCA) occlusion, followed by 24 h of reperfusion. Treadmill activity was then initiated 24 h after reperfusion for PostE. The severity of the brain damage was determined by infarct volume, apoptotic cell death, and neurological deficit at one and three days after reperfusion. We measured gluconeogenesis including oxaloacetate (OAA), phosphoenolpyruvate (PEP), pyruvic acid, lactate, ROS, and glucose via ELISA, as well as the location and expression of the key enzyme phosphoenolpyruvate carboxykinase (PCK)-1/2 via immunofluorescence. We also determined upstream pathways including forkhead transcription factor (FoxO1), p-FoxO1, 3-kinase (PI3K)/Akt, and p-PI3K/Akt via Western blot. Additionally, the cytoplasmic expression of p-FoxO1 was detected by immunofluorescence. Compared to non-exercise control, PostE (*p < .05) decreased brain infarct volumes, neurological deficits, and cell death at one and three days. PostE groups (*p < .05) saw increases in OAA and decreases in PEP, pyruvic acid, lactate, ROS, glucose levels, and tissue PCKs expression on both days. PCK-1/2 expressions were also significantly (*p < .05) suppressed by the exercise setting. Additionally, phosphorylated PI3K, AKT, and FoxO1 protein expression were significantly induced by PostE at one and three days (*p < .05). In this study, PostE reduced brain injury after stroke, in association with activated PI3K/AKT/FoxO1 signaling, and inhibited gluconeogenesis. These results suggest the involvement of FoxO1 regulation of gluconeogenesis underlying post-stroke neuroprotection.

Excess glutamine does not alter myotube metabolism or insulin sensitivity. Amino Acids 2022; 54:455-468.

Abstract
Glutamine is an amino acid previously linked with improved skeletal muscle metabolism and insulin signaling, however, past observations often use cell culture models with only supraphysiological concentrations. Additionally, past reports have yet to simultaneously investigate both metabolic outcomes and insulin signaling. The present report utilized cell culture experiments and measured the effects of both physiological and supraphysiological levels of glutamine on myotube metabolism and insulin signaling/resistance. It was hypothesized the addition of glutamine at any level would increase cell metabolism and related gene expression, as well as improve insulin signaling versus respective control cells. C2C12 myotubes were treated with glutamine ranging from 0.25 mM-4 mM (or media control) for 24 h to capture a range of physiological and supraphysiological concentrations. qRT-PCR was used to measure metabolic gene expression. Mitochondrial and glycolytic metabolism were measured via oxygen consumption and extracellular acidification rate, respectively. Insulin sensitivity (indicated by pAkt:Akt) and metabolism following glucose/insulin infusion were also assessed. Glutamine treatment consistently increased mitochondrial and glycolytic metabolism versus true controls (cells treated with media void of glutamine), however, supraphysiological glutamine did not enhance metabolism beyond that of cells with physiological levels of glutamine. Neither physiological nor supraphysiological levels of glutamine altered insulin signaling regardless of insulin stimulation or insulin resistance when compared with respective controls. These data demonstrate excess glutamine does not appear to alter myotube metabolism or glucose disposal when base levels of glutamine are present. Moreover, glutamine does not appear to alter insulin sensitivity regardless of level of insulin resistance or presence of insulin stimulation.

Transcriptomic and Metabolomic Analyses Reveal Inhibition of Hepatic Adipogenesis and Fat Catabolism in Yak for Adaptation to Forage Shortage During Cold Season. Front Cell Dev Biol 2022; 9:759521. [PMID: 35111749 PMCID: PMC8802892 DOI: 10.3389/fcell.2021.759521] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2021] [Accepted: 12/02/2021] [Indexed: 12/20/2022] Open
Abstract
Animals have adapted behavioral and physiological strategies to conserve energy during periods of adverse conditions. Hepatic glucose is one such adaptation used by grazing animals. While large vertebrates have been shown to have feed utilization and deposition of nutrients—fluctuations in metabolic rate—little is known about the regulating mechanism that controls hepatic metabolism in yaks under grazing conditions in the cold season. Hence, the objective of this research was to integrate transcriptomic and metabolomic data to better understand how the hepatic responds to chronic nutrient stress. Our analyses indicated that the blood parameters related to energy metabolism (glucose, total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, lipoprotein lipase, insulin, and insulin-like growth factor 1) were significantly (p < 0.05) lower in the cold season. The RNA-Seq results showed that malnutrition inhibited lipid synthesis (particularly fatty acid, cholesterol, and steroid synthesis), fatty acid oxidation, and lipid catabolism and promoted gluconeogenesis by inhibiting the peroxisome proliferator-activated receptor (PPAR) and PI3K-Akt signaling pathways. For metabolite profiles, 359 metabolites were significantly altered in two groups. Interestingly, the cold season group remarkably decreased glutathione and phosphatidylcholine (18:2 (2E, 4E)/0:0). Moreover, integrative analysis of the transcriptome and metabolome demonstrated that glycolysis or gluconeogenesis, PPAR signaling pathway, fatty acid biosynthesis, steroid biosynthesis, and glutathione metabolism play an important role in the potential relationship between differential expression genes and metabolites. The reduced lipid synthesis, fatty acid oxidation, and fat catabolism facilitated gluconeogenesis by inhibiting the PPAR and PI3K-Akt signaling pathways to maintain the energy homeostasis of the whole body in the yak, thereby coping with the shortage of forages and adapting to the extreme environment of the Qinghai-Tibetan Plateau (QTP).

Insight of their chemical characterization using HPLC-ESI-QTOF-MS/MS. JOURNAL OF ETHNOPHARMACOLOGY 2021; 269:113701. [PMID: 33346028 DOI: 10.1016/j.jep.2020.113701] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/11/2020] [Revised: 12/01/2020] [Accepted: 12/13/2020] [Indexed: 05/20/2023]
Abstract
ETHNOPHARMACOLOGY RELEVANCE Schinus terebinthifolius is traditionally used for its anti inflammatory capacity, and indicated as a cardioprotective agent, whereas, its preventive effect against atherogenic diet fed (AD) induced metabolic disorders and the underlying mechanisms has not yet been explored. AIM OF THE STUDY This study was undertaken to investigate the ameliorative role of Schinus terebinthifolius fruits extract (STFE) against cardiovascular problem, oxidative and inflammatory status related to obesity in rats fed an atherogenic diet. MATERIALS AND METHODS The metabolites profile in STFE was evaluated using HPLC-DAD-ESI-QTOF-MS/MS analysis. In Wistar rats, atherogenic diet was added for 9 weeks to induce lipid accumulation simultaneously with STFE (50 mg/kg b. w) or saline treatment. Biochemical, oxidant, and inflammatory criteria together with hepatic and arterial integrity examination were assessed. RESULTS A total of thirty three metabolites were identified using HPLC-DAD-ESI-QTOF-MS, among them masazino-flavanone was the major compound (2645.50 μg/g DW). The results indicated that STFE supplementation during 9 weeks (50 mg/kg b. w.) significantly attenuated the altered lipid profile by decreasing the levels of TC, TG, LDL-C and increasing the HDL-C content both in plasma and liver, when compared with the AD-group. The histological analysis using ORO staining revealed a decrease in the lipid droplet deposit in the cytoplasm of hepatocytes of STFE + AD group. The addition of STFE could improve the glycemic status of AD-treated rats by decreasing the glucose and insulin secretion, and ameliorating the hepatic glycogen synthesis. The harmful effects of atherogenic diet on hepatic oxidative stress indicators (MDA, PC, GSH, SOD, CAT, and GPx), biochemical markers (AST, ALT, LDH and ALP), and liver function, were found to be decreased by the addition of STFE. Moreover, the reduction of inflammatory markers (CRP, IL-6 and TNF-α), associated to alleviating of aortic oxidative stress and integrity, highlighted the positive anti-atherogenic effect of STFE. CONCLUSION Overall, the pleiotropic protective effect observed with S. terebinthifolius fruits might be related to the presence of various bioactive compounds.

Abstract
Newly emerging evidence has implicated that progesterone receptor component 1 (PGRMC1) plays a novel role not only in the lipid disturbance induced by atypical antipsychotic drugs (AAPD) but also in the deterioration of glucose homoeostasis induced by clozapine (CLZ) treatment. The present study aimed to investigate the role of PGRMC1 signaling on hepatic gluconeogenesis and glycogenesis in male rats following CLZ treatment (20 mg/kg daily for 4 weeks). Recombinant adeno-associated viruses (AAV) were constructed for the knockdown or overexpression of hepatic PGRMC1. Meanwhile, AG205, the specific inhibitor of PGRMC1 was also used for functional validation of PGRMC1. Hepatic protein expressions were measured by western blotting. Meanwhile, plasma glucose, insulin and glucagon, HbA1c and hepatic glycogen were also determined by assay kits. Additionally, concentrations of progesterone (PROG) in plasma, liver and adrenal gland were measured by a liquid chromatography-tandem mass spectrometry (LC-MS/MS) method. Our study demonstrated that CLZ promoted the process of gluconeogenesis and repressed glycogenesis, respectively mediated by PI3K-Akt-FOXO1 and GSK3β signaling via inhibition of PGRMC1-EGFR/GLP1R in rat liver, along with an increase in fasting blood glucose, HbA1c levels and a decrease in insulin and hepatic glycogen levels. Furthermore, through PGRMC1-EGFR/GLP1R-PI3K-Akt pathway, knockdown or inhibition (by AG205) of PGRMC1 mimics, whereas its overexpression moderately alleviates CLZ-induced glucose disturbances. Potentially, the PGRMC1 target may be regarded as a novel therapeutic strategy for AAPD-induced hepatic glucose metabolism disorder.

Intravenous Glutamine Administration Improves Glucose Tolerance and Attenuates the Inflammatory Response in Diet-Induced Obese Mice after Sleeve Gastrectomy. Nutrients 2020; 12:nu12103192. [PMID: 33086562 PMCID: PMC7603202 DOI: 10.3390/nu12103192] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/24/2020] [Revised: 10/08/2020] [Accepted: 10/15/2020] [Indexed: 11/17/2022] Open
Abstract
Obesity is a health problem associated with many metabolic disorders. Weight reduction can effectively alleviate obesity-associated complications. Sleeve gastrectomy is a commonly used bariatric surgery and is considered safe and effective for improving outcomes. Glutamine (GLN) is an amino acid with anti-oxidative and anti-inflammatory properties. This study used a mouse model of sleeve gastrectomy to investigate the impacts of intravenous GLN administration on glucose tolerance and adipocyte inflammation short-term after surgery. C57BL6 male mice were divided into normal control (NC) and high-fat diet groups. The high-fat diet provided 60% of energy from fat for 10 weeks to induce obesity. Mice fed the high-fat diet were then assigned to a sham (SH) or sleeve gastrectomy with saline (S) or GLN (G) groups. The S group was intravenously injected with saline, while the G group was administered GLN (0.75 g/kg body weight) via a tail vein postoperatively. Mice in the experimental groups were sacrificed on day 1 or 3 after the surgery. Results showed that obesity resulted in fat accumulation, elevated glucose levels, and adipokines production. Sleeve gastrectomy aggravated expressions of inflammatory cytokine and macrophage infiltration markers, cluster of differentiation 68 (CD68), epidermal growth factor-like module-containing mucin-like hormone receptor-like 1 (EMR-1), and macrophage chemoattractant protein-1, in adipose tissues. Treatment of obese mice with GLN downregulated hepatic proteomic profiles associated with the gluconeogenesis pathway and improved glucose tolerance. Moreover, macrophage infiltration and adipose tissue inflammation were attenuated after the sleeve gastrectomy. These findings imply that postoperative intravenous GLN administration may improve glucose tolerance and attenuate inflammation shortly after the bariatric surgery in subjects with obesity.

Abstract
Objective The SAM- and SH3-domain containing 1 gene (SASH1) has been considered as a tumor suppressor in some cancers. Nevertheless, the effect of SASH1 on the proliferation and invasion of human skin squamous cell carcinoma (cSCC) remains poorly understood. Therefore, the purpose of the present study was to observe the potential role of SASH1 in cSCC and investigate its underlying mechanisms. Methods The overexpression of SASH1 was constructed by transfecting the pcDNA3.1/SASH1 vector into SCL-1 and A431 cells, and SASH1 knockdown was generated by transfecting the SASH1 siRNA into cSCC cells. Then, cell proliferation, invasion, apoptosis, and Akt pathway were observed. Results The expression levels of SASH1 mRNA and protein were greatly reduced in cSCC cells. The overexpression of SASH1 inhibited the viability and invasion of cSCC cells, while its knockdown induced the viability and invasion of cSCC cells. The overexpression of SASH1 also suppressed the expression levels of p-Akt and its target genes, including cyclin D1, Bcl-2, and metal matrix proteinase 2(MMP-2). By contrast, SASH1 knockdown exerted the opposite role. Furthermore, inhibition of Akt obviously decreased the inducible effect of cSCC knockdown on the proliferation and invasion of cSCC cells. Conclusion Overall, these results found that SASH1 inhibits the proliferation and invasion of cSCC cells via suppressing Akt cascade, indicating a tumor inhibitory effect of SASH1 in cSCC cells.

Abstract
Obesity is associated with a wide range of chronic diseases, including cancer. It has been noted that the integration of metabolic mechanisms in obese patients may predispose them to suffer from cancer incidence and its progression. Thus, a better understanding of metabolic alterations in obesity, along with the development of feasible therapeutic approaches for intervention, are theoretically relevant to the prevention and treatment of cancer malignancy. Using a syngeneic tumor model involving Lewis Lung Carcinoma (LLC) cells and C57BL/6 mice fed with a high fat diet, obesity was found to be associated with dysregulated glucose and glutamine metabolism, inflammation, along with platelet activation and the promotion of tumor growth. Tumor-bearing lowered glucose levels while moderately increasing inflammation, platelet activation, and glutamine levels. The antiplatelet drug aspirin, mitigated tumor growth in obese mice, paralleled by a decrease in systemic glucose, insulin, inflammation, platelet activation, glutamine and tumor expression of cell proliferation, aerobic glycolysis, glutaminolysis, platelets, and leukocyte molecules. The anti- and pro-cell proliferation, aerobic glycolysis, and glutaminolysis effects of aspirin and glutamine were further demonstrated in a LLC cell study. Although there remains limitations to our experiments, glucose and glutamine metabolism are proposed targets for the anticancer effects of aspirin.
