Luo Y, Zhang Z, Zheng W, Zeng Z, Fan L, Zhao Y, Huang Y, Cao S, Yu S, Shen L. Molecular Mechanisms of Plant Extracts in Protecting Aging Blood Vessels. Nutrients 2024; 16:2357. [PMID: 39064801 PMCID: PMC11279783 DOI: 10.3390/nu16142357] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/13/2024] [Revised: 07/09/2024] [Accepted: 07/19/2024] [Indexed: 07/28/2024] Open
Abstract
Plant Extracts (PE) are natural substances extracted from plants, rich in various bioactive components. Exploring the molecular mechanisms and interactions involved in the vascular protective effects of PE is beneficial for the development of further strategies to protect aging blood vessels. For this review, the content was obtained from scientific databases such as PubMed, China National Knowledge Infrastructure (CNKI), and Google Scholar up to July 2024, using the search terms "Plant extracts", "oxidative stress", "vascular aging", "endothelial dysfunction", "ROS", and "inflammation". This review highlighted the effects of PE in protecting aging blood vessels. Through pathways such as scavenging reactive oxygen species, activating antioxidant signaling pathways, enhancing respiratory chain complex activity, inhibiting mitochondrial-reactive oxygen species generation, improving nitric oxide bioavailability, downregulating the secretion of inflammatory factors, and activating sirtuins 1 and Nrf2 signaling pathways, it can improve vascular structural and functional changes caused by age-related oxidative stress, mitochondrial dysfunction, and inflammation due to aging, thereby reducing the incidence of age-related cardiovascular diseases.

Abstract
Following a request from the European Commission, the EFSA Panel on Nutrition, Novel Foods and Food Allergens (NDA) was asked to deliver an opinion on ashitaba sap as a novel food (NF) pursuant to Regulation (EU) 2015/2283. Ashitaba sap is collected from harvested stems of Angelica keiskei plants. The principal constituents of the sap with regard to the safety assessment are chalcones (1%-2.25%) and furanocoumarins (< 0.01%). The applicant proposed to use the NF in food supplements at a maximum dose of 780 mg per day. The target population is adults excluding pregnant and lactating women. Taking into consideration the composition of the NF and the proposed uses, the composition of the NF is not nutritionally disadvantageous. There are no concerns regarding genotoxicity of the NF. Based on a 90-day oral toxicity study performed with the product as intended to be placed on the market (30% ashitaba sap powder and 70% cyclodextrins), the Panel establishes a safe dose of 0.5 mg/kg body weight (bw) per day for the product as it is intended to be placed on the market. For the target population, i.e. adults, this safe dose corresponds to 35 mg per day of the product as it is intended to be placed on the market and 137 mg per day of the NF, which is lower than the use level proposed by the applicant. The Panel concludes that the NF is safe for the target population at intake levels up to 137 mg per day.

Abstract
Angelica keiskei Koidzumi (Ashitaba) is a traditional folk medicine and health supplement in Japan. Ashitaba yellow stem exudate (AYE) contains abundant chalcones and thus has the potential to treat and prevent many pathological states such as cancer, inflammation, obesity, diabetics, thrombosis, and hypertension. Levels of plasminogen activator inhibitor 1 (PAI-1), a key regulator of the fibrinolytic system, increase with age in mouse plasma. Therefore, we aimed to determine the effects of AYE on plasma thrombotic parameters in aging mice. Long-term (52 weeks) AYE supplementation significantly decreased age-induced increases of PAI-1 in mouse plasma. Supplementation with AYE decreased levels of the acute-phase and fibrinolytic protein plasma plasminogen, and significantly decreased those of tumor necrosis factor α. These results suggested that continuous intake of AYE throughout life decreases age-induced systemic inflammation and prevents thrombotic tendencies without affecting body weight gain in aged mice. Our findings showed that supplementing diets with AYE might help to prevent thrombotic diseases in elderly individuals.

Abstract
Although multiple studies have shown that Angelica keiskei of the Umbelliferae family has potent anti-inflammatory and antioxidative activities and that it reduces the serum bile acids in humans, whether A. keiskei has protective effects against cholestasis-induced liver injury remains unexplored until now. This study tests the hypothesis that Angelica keiskei root extract (AKE) alleviates liver injury, inflammation, and fibrosis in mouse models of acute cholestasis induced by bile duct ligation (BDL). Oral administration of AKE (200 or 500 mg/kg) attenuated hepatocellular necrosis and significantly reduced serum levels of bile acids and bilirubin in BDL mice. The critical enzyme of bile acid synthesis, CYP7A1, was repressed by AKE, suggesting that reduced bile acid production may contribute to liver protection. Moreover, we determined through gene expression and cytokine analysis and histological examination that AKE treatment decreased liver inflammation, oxidative stress, and fibrosis. AKE also suppressed the NF-κB pathway, suggesting this as a possible mediator of its anti-inflammatory effect. Our findings substantiate that AKE may be promising for treating cholestatic liver diseases in the future.

Abstract
Background Herbs are commonly used to treat cardiovascular diseases in various traditional medicine. On the other hand, herb-drug interactions are most commonly encountered with conventional antiplatelet and anticoagulant drug prescriptions. This review presents a compilation of plants investigated for antiplatelet and anticoagulation recently and enumerates their possible lead compounds responsible for its action for paving further drug discovery and knowledge update. Main body of the abstract Information about the herbs was withdrawn from the PubMed database of the previous 5 years. We also hand-searched the bibliography of relevant articles for the acquisition of additional information. About 72 herbal sources were identified with the effect of antiplatelet activity, antithrombotic activity, and anticoagulant activity. Bioactive compounds and various secondary metabolites responsible for it, such as alkaloids, saponins, flavonoids, coumarins, polyphenols, furan derivatives, iridoid glycosides, sesquiterpenes, aporphine compounds, were reported. Conclusion Newer pharmacological moieties are needed to prevent or reduce the adverse effects of current anti-thrombotic agents and to improve the safety of patients and cost-effectiveness.

Abstract
Since a decrease in muscle mass leads to an increased risk of mortality, the prevention of muscle wasting contributes to maintaining the quality of life. Recently, we reported that glabridin, a prenylated flavonoid in licorice, prevents dexamethasone-induced muscle loss. In this study, we focused on the other prenylated chalcones 4-hydroxyderricin and xanthoangelol in Ashitaba (Angelica keiskei) and investigated their prevention effect on dexamethasone-induced muscle loss. It was found that 4-hydroxyderricin and xanthoangelol significantly prevented dexamethasone-induced protein degradation in C2C12 myotubes by suppressing the expression of ubiquitin ligases, Cbl-b and MuRF-1. These prenylated chalcones acted as the antagonists of the glucocorticoid receptor and inhibited the binding of dexamethasone to this receptor and its subsequent nuclear translocation. In addition, the chalcones suppressed the phosphorylation of p38 and FoxO3a as the upstream factors for ubiquitin ligases. Dexamethasone-induced protein degradation and upregulation of Cbl-b were attenuated by the knockdown of the glucocorticoid receptor but not by the knockdown of p38. In male C57BL/6J mice, the Ashitaba extract, containing 4-hydroxyderricin and xanthoangelol, suppressed dexamethasone-induced muscle mass wasting accompanied by a decrease in the expression of ubiquitin ligases by inhibiting the nuclear translocation of the glucocorticoid receptor and phosphorylation of FoxO3a. In conclusion, 4-hydroxyderricin and xanthoangelol are effective compounds to inhibit steroid-induced muscle loss.

Abstract
Angelica keiskei koidzumi (ashitaba) is consumed as a traditional folk medicine and health food in Japan. Ashitaba extract contains abundant flavonoids containing chalcones. Plasminogen activator inhibitor-1 (PAI-1) is the primary physiological inhibitor of tissue plasminogen activator. Excessive amounts of PAI-1 in plasma disrupt the fibrinolytic balance and promote a prothrombotic state with which thrombosis and cardiovascular diseases are associated. In the present study, we investigated the effects of ashitaba yellow exudate (AE) on enhanced PAI-1 levels in Tsumura Suzuki obese diabetic (TSOD) mice. AE significantly decreased food efficiency and plasma PAI-1 in TSOD mice but did not affect lean control Tsumura Suzuki nonobese (TSNO) mice. AE also decreased some parameters in the plasma, such as glucose, insulin, tumor necrosis factor alpha (TNF-α) and gains in body weight, subcutaneous, mesenteric fat weight in TSOD mice but had little effect on these parameters in TSNO mice. Levels of adipose PAI-1 were significantly higher in TSOD than in TSNO mice. Major sources of plasma PAI-1 are thought to be adipose tissue and liver. AE significantly suppressed PAI-1 protein levels in the livers of both TSOD and TSNO mice. These results suggest that AE decreased plasma PAI-1 levels by suppressing both the adipose tissue retention of PAI-1 protein and liver PAI-1 production in TSOD mice. Supplementing the diet with AE might help to prevent thrombotic diseases or alleviate the risk of thrombotic diseases as well as to suppress metabolic state in obese individuals.

Abstract
Angelica keiskei (Miq.) Koidz. (Umbelliferae) has traditionally been used to treat dysuria, dyschezia, and dysgalactia as well as to restore vitality. Recently, the aerial parts of A. keiskei have been consumed as a health food. Various flavonoids, coumarins, phenolics, acetylenes, sesquiterpene, diterpene, and triterpenes were identified as the constituents of A. keiskei. The crude extracts and pure constituents were proven to inhibit tumor growth and ameliorate inflammation, obesity, diabetics, hypertension, and ulcer. The extract also showed anti-thrombotic, anti-oxidative, anti-hyperlipidemic, anti-viral, and anti-bacterial activities. This valuable herb needs to be further studied and developed not only to treat these human diseases but also to improve human health. Currently A. keiskei is commercialized as a health food and additives in health drinks. This article presents a comprehensive review of A. keiskei and its potential place in the improvement of human health.

Abstract
BACKGROUND/OBJECTIVE Although Angelica keiskei (AK) has widely been utilized for the purpose of general health improvement among Asian, its functionality and mechanism of action. The aim of this study was to determine the protective effect of ethanol extract of AK (AK-Ex) on acute hepatotoxicity induced by acetaminophen (AAP) in HepG2 human hepatocellular liver carcinoma cells and HepaRG human hepatic progenitor cells. MATERIALS/METHODS AK-Ex was prepared HepG2 and HepaRG cells were cultured with various concentrations and 30 mM AAP. The protective effects of AK-Ex against AAP-induced hepatotoxicity in HepG2 and HepaRG cells were evaluated using 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide, lactate dehydrogenase (LDH) assay, flow cytometry, and Western blotting. RESULTS AK-Ex, when administered prior to AAP, increased cell growth and decreased leakage of LDH in a dose-dependent manner in HepG2 and HepaRG cells against AAP-induced hepatotoxicity. AK-Ex increased the level of Bcl-2 and decreased the levels of Bax, Bok and Bik decreased the permeability of the mitochondrial membrane in HepG2 cells intoxicated with AAP. AK-Ex decreased the cleavage of poly (ADP-ribose) polymerase (PARP) and the activation of caspase-9, -7, and -3. CONCLUSIONS These results demonstrate that AK-Ex downregulates apoptosis via intrinsic and extrinsic pathways against AAP-induced hepatotoxicity. We suggest that AK could be a useful preventive agent against AAP-induced apoptosis in hepatocytes.

Abstract
OBJECTIVE Obesity-induced inflammation plays a pivotal role in the pathogenesis of insulin resistance and type 2 diabetes. Xanthoangelol (XA) and 4-hydroxyderrcin (4-HD), phytochemicals extracted from Angelica keiskei, have been reported to possess various biological properties. Whether XA and 4-HD alleviate obesity-induced inflammation and inflammation-induced adipocyte dysfunction was investigated. METHODS For the in vitro study, a co-culture system composed of macrophages and adipocytes and macrophages stimulated with conditioned medium derived from fully differentiated adipocytes was conducted. For the in vivo study, mice were fed a high-fat diet supplemented with XA for 14 weeks. RESULTS XA and 4-HD suppressed inflammatory factors in co-culture system. Moreover, treatment of RAW macrophages with XA and 4-HD moderated the suppression of uncoupling protein 1 promoter activity and gene expression in C3H10T1/2 adipocytes, which was induced by conditioned medium derived from LPS-stimulated RAW macrophages. Also, XA and 4-HD inhibited c-Jun N-terminal kinase phosphorylation, nuclear factor-κB, and activator protein 1, the last two being transcription activators in activated macrophages. Furthermore, in mice fed the high-fat diet, XA reduced inflammatory factors within the white adipose tissue. CONCLUSIONS These results suggest that XA and 4-HD might be promising phytochemicals to suppress obesity-induced inflammation and inflammation-induced adipocyte dysfunction.

Abstract
BACKGROUND Brazilian propolis has many biological activities including the ability to help prevent thrombotic diseases, but this particular effect has not been proven. Plasma levels of plasminogen activator inhibitor-1 (PAI-1), an inhibitor of fibrinolysis, increase under inflammatory conditions such as infection, obesity and atherosclerosis and such elevated levels predispose individuals to a risk of developing thrombotic diseases. AIM This study aimed to determine the effects of a diet containing Brazilian propolis on lipopolysaccharide (LPS)-induced increases in plasma PAI-1 levels. MATERIALS AND METHODS Mice were fed with a diet containing 0.5% (w/w) Brazilian propolis for 8 weeks. Thereafter, the mice were subcutaneously injected with saline containing 0.015 mg/kg of LPS and sacrificed 4 h later. RESULTS Orally administered Brazilian propolis significantly suppressed the LPS-induced increase in PAI-1 antigen and its activity in mouse plasma. CONCLUSION This study indicated that Brazilian propolis contains natural products that can decrease thrombotic tendencies in mice.

Abstract
The ethyl acetate-soluble fraction from the ethanolic extract of Angelica keiskei showed potent inhibitory activity against the production of nitric oxide (NO) in lipopolysaccharide (LPS)-activated RAW 264.7 cells. We identified seven chalcones (1-7) from EtOAc-soluble fractions through the activity-guided separation. Four active principles, identified as 4-hydroxyderrcine (1), xanthoangelol E (2), xanthokeismin A (4), and xanthoangelol B (5), inhibited the production of NO and the expression of proinflammatory cytokines, interleukin (IL)-1β and IL-6, in LPS-activated macrophages. Western blotting and reverse transcription-polymerase chain reaction analysis demonstrated that these chalcones attenuated protein and mRNA levels of inflammatory enzymes such as inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2). Moreover, these active compounds suppressed the degradation of inhibitory-κBα (I-κBα) and the translocation of nuclear factor κB (NF-κB) into nuclei of LPS-activated macrophages. These data demonstrate that four chalcones (1, 2, 4, and 5) from A. keiskei can suppress the LPS-induced production of NO and the expression of iNOS/COX-2 genes by inhibiting the degradation of I-κBα and nuclear translocation of NF-κB. Taken together, four chalcones from A. keiskei may have efficacy as anti-inflammatory agents.

Abstract
BACKGROUND Tumor growth and metastasis have been closely associated with the M2 macrophage-induced activation of tumor-associated macrophages (TAMs). PURPOSE The antitumor and antimetastatic actions of xanthangelol and 4-hydroxyderricin on the role of M2 macrophages in the TAMs of highly metastatic osteosarcoma LM8-bearing mice have not yet been fully elucidated. In order to clarify the mechanisms underlying the antitumor and antimetastatic actions of the above chalcones, we performed in vivo and in vitro studies. STUDY DESIGN The antitumor and antimetastatic actions of xanthoangelol and 4-hydroxyderricin were examined in vivo and the effects on M2 macrophage differentiation and activation were examined in vitro. METHODS We examined the antitumor and antimetastatic effects of xanthoangelol and 4-hydroxyderricin on highly metastatic osteosarcoma LM8-bearing mice (in vivo). Further, we examined their effects on the differentiation of interleukin (IL)-4 plus IL-13-induced M2 macrophages and activation of IL-4 plus IL13-induced M2 macrophages (in vitro). We also investigated the expression and phosphorylation of signal transducer and activator of transcript 3 (Stat 3) in the differentiation process of M2-polarized macrophages (in vitro). RESULTS Xanthoangelol or 4-hydroxyderricin (25 or 50 mg/kg, twice daily) inhibited tumor growth, metastasis to the lung and liver, and TAM expression in tumors. In addition, xanthoangelol (10, 25 or 50 μM) and 4-hydroxyderricin (5, 10, 25 or 50 μM) inhibited the production of IL-10 and monocyte chemoattractant protein (MCP)-1 in M2-polarized macrophages. This result indicated that xanthoangelol and 4-hydroxyderricin inhibited the activation of M2 macrophages. Furthermore, xanthoangelol (5-50 μM) inhibited the phosphorylation of Stat 3 without affecting the expression of the Stat 3 protein in the differentiation process of M2 macrophages, which indicated that these chalcones inhibited the differentiation of M2 macrophages. CONCLUSION These findings suggested that the antitumor and antimetastatic actions of xanthoangelol and 4-hydroxyderrcin might be attributed to the regulated activated TAMs through the inhibition of activation and differentiation of M2 macrophages in the tumor microenvironment.

Abstract
Angelica keiskei (Shin-sun cho) is an edible higher plant with the beneficial preventive effects on cancer, hypertension, and coronary heart disease. Two bioactive chalcones of Shin-sun cho, xanthoangelol (1) and 4-hydroxyderricin (2), were separated simultaneously by using high-speed counter-current chromatography with a two-phase solvent system composed of n-hexane-EtOAc-MeOH-H2O (9:5:9:4). Only nonconsuming processes, solvent fractionations and Sephadex LH-20 column chromatography, were conducted as presteps. Xanthoangelol (1, 35.9 mg, 99.9 % purity at 254 and 365 nm) and 4-hydroxyderricin (2, 4.4 mg, 98.7 % purity at 254 nm and 98.8 % purity at 365 nm) were successfully purified from 70 mg of the processed extract from A. keiskei. The structures of two compounds were confirmed by (1)H- and (13)C-NMR analysis.

Abstract
Two main chalcones, 4-hydroxyderricin and xanthoangelol, from Ashitaba, which is a food ingredient and a folk medicine in Asia, have been demonstrated to modulate lipid metabolism in 3T3-L1 and HepG2 cells. In this study, we investigated the effects of Ashitaba extract on adiposity in mice fed a high-fat (HF) diet and its underlying mechanisms based on adipose tissue and hepatic lipid metabolism. C57BL/6 mice were fed a normal or HF diet supplemented with Ashitaba extract (0.01% and 0.1%, w/w) for 16 weeks. Ashitaba extract suppressed the HF diet-induced body weight gain and fat deposition in white adipose tissue, reduced plasma cholesterol, glucose, and insulin levels, increased the adiponectin level, lowered triglyceride and the liver cholesterol content, increased phosphorylation of AMP-activated protein kinase (AMPK) in adipose tissue and liver, inhibited lipogenesis in adipose tissue by down-expression of peroxisome proliferator-activated receptor (PPAR) γ, CCAAT/enhancer-binding protein α and sterol regulatory element-binding protein 1 (SREBP1), inhibited lipogenesis in the liver by down-expression of SREBP1 and its target enzyme fatty acid synthase, and promoted fatty acid oxidation by up-expression of carnitine palmitoyltransferase-1A and PPARα. In conclusion, Ashitaba extract can possibly prevent adiposity through modulating lipid metabolism through phosphorylation of AMPK in adipose tissue and liver.

Abstract
Excessive lipid accumulation in the liver has been proposed to cause hyperlipidemia, diabetes and fatty liver disease. 4-Hydroxyderricin (4HD), xanthoangelol (XAG), cardamonin (CAR) and flavokawain B (FKB) are chalcones that have exhibited various biological effects against obesity, inflammation, and diabetes; however, little is known about the inhibitory effects of these chalcones on fatty liver disease. In the present study, we investigated the ability of 4HD, XAG, CAR, and FKB to reduce lipid accumulation in hepatocytes. When HepG2 cells were treated with a mixture of fatty acids (FAs; palmitic acid : oleic acid = 1 : 2 ratio), significant lipid accumulation was observed. Under the same experimental conditions, addition of chalcones at 5 μM significantly suppressed the FA-induced lipid accumulation. We found that the expression of sterol regulatory element-binding protein-1 (SREBP-1), a key molecule involved in lipogenesis, was decreased in these chalcone-treated cells. We also found that these chalcones increased the expression of peroxisome proliferator-activated receptor α (PPARα), which is involved in FA oxidation. Moreover, these chalcones increased phosphorylation of AMP-activated protein kinase (AMPK) and liver kinase B1 (LKB1), upstream regulators of SREBP-1 and PPARα. We confirmed that an AMPK inhibitor, compound C, reversed chalcone-induced changes in SREBP-1 and PPARα expression in the HepG2 cells. Collectively, we found that 4HD, XAG, CAR, and XAG attenuated lipid accumulation through activation of the LKB1/AMPK signaling pathway in HepG2 cells.

Abstract
The Japanese herb, Ashitaba (Angelica keiskei Koidzumi), contains two prenylated chalcones, 4-hydroxyderricin and xanthoangelol, which are considered to be the major active compounds of Ashitaba. However, their effects on inflammatory responses are poorly understood. In the present study, we investigated the effects and underlying molecular mechanisms of 4-hydroxyderricin and xanthoangelol on lipopolysaccharide (LPS)-induced inflammatory responses in RAW264 mouse macrophages. LPS-mediated production of nitric oxide (NO) was markedly reduced by 4-hydroxyderricin (10 μM) and xanthoangelol (5 μM) compared with their parent compound, chalcone (25 μM). They also inhibited LPS-induced secretion of tumor necrosis factor-alpha (TNF-α) and expression of inducible NO synthase (iNOS) and cyclooxygenase-2 (COX-2). Although chalcone decreased the DNA-binding activity of both activator protein-1 (AP-1) and nuclear factor-kappa B (NF-κB), 4-hydroxyderricin and xanthoangelol suppressed only AP-1 and had no effect on NF-κB. On the other hand, all of the tested chalcones reduced the phosphorylation (at serine 536) level of the p65 subunit of NF-κB. 4-Hydroxyderricin and xanthoangelol may be promising for the prevention of inflammatory diseases.

Abstract
Abstract
Objectives
Psoralea corylifolia is a plant widely used in traditional Chinese medicine, e.g. for its chemopreventive effect. To identify active substances responsible for this effect, we investigated pharmacological effects of 11 compounds isolated from the seeds of this plant (newly described substances: 7, 2′, 4′-trihydroxy-3-arylcoumarin and psoracoumestan).
Methods
The influence of distinct compounds on different signal transduction pathways (cell proliferation, survival, angiogenesis and metastasis) was screened via analysis of the activity of 24 protein kinases, mitogen activated protein kinase phosphorylation via Western blot, cytotoxicity was shown using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay and determination of caspase activity. Oxidative stress was detected via 2′,7′-dichlorofluorescein fluorescence.
Key findings
Some compounds showed cytotoxic effects (H4IIE, Hct116, C6 cells) mainly mediated via induction of apoptosis. Distinct compounds caused a strong inhibition of MAPK/ERK kinase (MEK) phosphorylation, weak effects on extracellular-signal regulated kinase (ERK) phosphorylation and no significant effect on p38 and c-Jun amino-terminal kinase. Corylifol C and, to a lesser extent, xanthoangelol are potent protein kinase inhibitors (inhibitory concentration 50% values for epidermal growth factor receptor (EGFR): 1.1 and 4.4 × 10−6 μg/ml, respectively). Because EGFR, MEK and ERK are kinases involved in cellular proliferation, an inhibition of these enzymes may be useful to cause chemopreventive effects.
Conclusions
Distinct compounds isolated from P. corylifolia showed a high potential to influence cellular pathways, e.g. by inhibition of protein kinases that may be interesting for pharmacological purposes.

Abstract
SCOPE Adipocytes differentiation is deeply involved in the onset of obesity. 4-Hydroxyderricin (4HD) and xanthoangelol (XAG) are the chalcones that are derived from Ashitaba (Angelica keiskei). In this study, we demonstrated the inhibitory effects of these chalcones on adipocytes differentiation. METHODS AND RESULTS 4HD and XAG suppressed intracellular lipid accumulation by Oil red O staining at 5 μM without cytotoxicity. They inhibited adipocytes differentiation accompanied by down-expression of adipocyte-specific transcription factors, CCAAT/enhancer-binding protein-β (C/EBP-β), C/EBP-α, and peroxisome proliferator-activated receptor gamma (PPAR-γ) using RT-PCR and Western blotting analysis. To obtain insights into the underlying mechanism, the activation of AMP-activated protein kinase (AMPK) and mitogen-activated protein kinase pathways was investigated. These two chalcones promoted phosphorylation of AMPK and acetyl CoA carboxylase during differentiation of 3T3-L1 adipocytes accompanied by a decrease in glycerol-3-phosphate acyl transferase-1 and an increase in carnitine palmitoyltransferase-1 mRNA expression. These chalcones also promoted phosphorylation of extracellular signal-regulated kinases and Jun aminoterminal kinases, but not p38. Moreover, the inhibitors for AMPK and extracellular signal-regulated kinases abolished the chalcones-caused down-expression of C/EBP-β, C/EBP-α, and PPAR-γ. Treatment with Jun aminoterminal kinases inhibitor abolished the down-expression of C/EBP-α and PPAR-γ, but not C/EBP-β. CONCLUSION 4HD and XAG inhibit adipocytes differentiation through AMPK and mitogen-activated protein kinase pathways, resulting in the down-expression of adipocyte-specific transcription factors.
