Choi JI, Song WS, Koh DH, Kim EY. In Silico and In Vitro multiple analysis approach for screening naturally derived ligands for red seabream aryl hydrocarbon receptor. ECOTOXICOLOGY AND ENVIRONMENTAL SAFETY 2024; 275:116262. [PMID: 38569320 DOI: 10.1016/j.ecoenv.2024.116262] [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: 12/07/2023] [Revised: 03/20/2024] [Accepted: 03/23/2024] [Indexed: 04/05/2024]
Abstract
The aryl hydrocarbon receptor (AHR) is a key ligand-dependent transcription factor that mediates the toxic effects of compounds such as dioxin. Recently, natural ligands of AHR, including flavonoids, have been attracting physiological and toxicological attention as they have been reported to regulate major biological functions such as inflammation and anti-cancer by reducing the toxic effects of dioxin. Additionally, it is known that natural AHR ligands can accumulate in wildlife tissues, such as fish. However, studies in fish have investigated only a few ligands in experimental fish species, and the AHR response of marine fish to natural AHR ligands of various other structures has not been thoroughly investigated. To explore various natural AHR ligands in marine fish, which make up the most fish, it is necessary to develop new screening methods that consider the specificity of marine fish. In this study, we investigated the response of natural ligands by constructing in vitro and in silico experimental systems using red seabream as a model species. We attempted to develop a new predictive model to screen potential ligands that can induce transcriptional activation of red seabream AHR1 and AHR2 (rsAHR1 and rsAHR2). This was achieved through multiple analyses using in silico/ in vitro data and Tox21 big data. First, we constructed an in vitro reporter gene assay of rsAHR1 and rsAHR2 and measured the response of 10 representatives natural AHR ligands in COS-7 cells. The results showed that FICZ, Genistein, Daidzein, I3C, DIM, Quercetin and Baicalin induced the transcriptional activity of rsAHR1 and rsAHR2, while Resveratrol and Retinol did not induce the transcriptional activity of rsAHR isoforms. Comparing the EC50 values of the respective compounds in rsAHR1 and rsAHR2, FICZ, Genistein, and Daidzein exhibited similar isoform responses, but I3C, Baicalin, DIM and Quercetin show the isoform-specific responses. These results suggest that natural AHR ligands have specific profiling and transcriptional activity for each rsAHR isoform. In silico analysis, we constructed homology models of the ligand binding domains (LBDs) of rsAHR1 and rsAHR2 and calculated the docking energies (U_dock values) of natural ligands with measured in vitro transcriptional activity and dioxins reported in previous studies. The results showed a significant correlation (R2=0.74(rsAHR1), R2=0.83(rsAHR2)) between docking energy and transcriptional activity (EC50) value, suggesting that the homology model of rsAHR1 and rsAHR2 can be utilized to predict the potential transactivation of ligands. To broaden the applicability of the homology model to diverse compound structures and validate the correlation with transcriptional activity, we conducted additional analyses utilizing Tox21 big data. We calculated the docking energy values for 1860 chemicals in both rsAHR1 and rsAHR2, which were tested for transcriptional activation in Tox21 data against human AHR. By comparing the U_dock energy values between 775 active compounds and 1085 inactive compounds, a significant difference (p<0.001) was observed between the U_dock energy values in the two groups, suggesting that the U_dock value can be applied to distinguish the activation of compounds. Furthermore, we observed a significant correlation (R2=0.45) between the AC50 of Tox21 database and U_dock values of human AHR model. In conclusion, we calculated equations to translate the results of an in silico prediction model for ligand screening of rsAHR1 and rsAHR2 transactivation. This ligand screening model can be a powerful tool to quantitatively estimate AHR transactivation of major marine agents to which red seabream may be exposed. The study introduces a new screening approach for potential natural AHR ligands in marine fish, based on homology model-docking energy values of rsAHR1 and rsAHR2, with implications for future agonist development and applications bridging in silico and in vitro data.

Abstract
Plant-based diets (PBDs) are renowned for managing and developing bioactive chemical inhibitors to combat obesity, a well-known global public health concern. There are currently no published research studies examining the effects of food plant mucilage dietary supplements on animal models of obesity induced by high-fat diets (HFD). The present research investigated the anti-obesity properties of the culinary plant Pedalium murex L. mucilage (PMM) in obese albino male rats models fed HFD. PMM's HR-LCMS phytochemical profiling and in silico evaluation of anti-obesity and drug-likeness using Schrodinger's Glide, QikProp, and GROMACS modules were also investigated. In vivo, anti-obesity model animal rat's daily dietary intake, common blood biochemical parameters, and histological examination of the liver and kidney tissues for the development of macrovesicular and microvesicular steatosis were all performed. Among the 46 Phytochemicals profiled, 7(14)-Bisabolene-2, 3, 10,11tetrol, Moschamine, and N-Feruloyltyramine show prominent anti-obesity activity and drug-like characteristics in silico. Rats given PMM showed significantly lower serum levels of total cholesterol (TC), low-density lipoprotein (LDL), and triglycerides (TGs), increased levels of high-density lipoprotein (HDL), as well as macro-and microvesicular steatosis, lobular inflammation of the liver and kidney tissues. This suggests that PMM is an effective natural anti-obesity therapeutic ingredient or dietary supplement with a high concentration of anti-obesity phytochemicals that mainly satisfies the needs for such natural anti-obesity medicine or a supplement.Communicated by Ramaswamy H.

Abstract
Gomisin C is a lignan isolated from the fruit of Schisandra chinensis. The current study aimed to investigate the effect of gomisin C on lipid accumulation in adipocytes and its underlying mechanism. Gomisin C effectively inhibited lipid accumulation by downregulating adipogenic factors such as PPARγ and C/EBPα. Gomisin C-mediated suppression of lipid accumulation occurred in the early adipogenic stage; C/EBPβ was downregulated by 55%, while KLF2 was upregulated by 1.5-fold. Gomisin C significantly reduced the production of reactive oxygen species but upregulated antioxidant enzymes, including catalase, SOD1, and Gpx at the mRNA level. Gomisin C regulated NRF2-KEAP1 pathway by increasing NRF2 and decreasing KEAP1, in protein abundance. Furthermore, gomisin C suppressed the JAK2-STAT signaling pathway by decreasing phosphorylation. Taken together, gomisin C reduced early adipogenesis and ROS production by inhibiting the JAK2-STAT signaling pathway but activating the NRF2-KEAP1 signaling pathway.

Abstract
The stability of hydrophobic bioactive compound indole-3-carbinol (I3C) is a challenge for application. In this work, Pickering emulsions were prepared to encapsulate I3C. As the emulsifier, high amylose corn starch was pretreated by acid hydrolysis, afterwards modified by different concentrations of octenyl succinic anhydride (OSA), and their emulsions were evaluated. The XRD, SEM and FTIR results indicated the successful modification. ζ-potential, mean droplet size and emulsification index (EI) of the emulsions confirmed that modified starch with a higher degree of substitution (DS) was more effective for enhancing the storage stability. The results of encapsulation efficiency (EE) and retention degree of I3C after 14 d also proved the assumption. Moreover, the Pickering emulsions protected I3C against ultraviolet light and achieved controlled release in vitro. The food-grade Pickering emulsion loading I3C is promising to be used as a nutrient or dietary supplement for food applications.

Abstract
Obesity and metabolic disorders have gradually become public health-threatening problems. The metabolic disorder is a cluster of complex metabolic abnormalities which are featured by dysfunction in glucose and lipid metabolism, and results from the increasing prevalence of visceral obesity. With the core driving factor of insulin resistance, metabolic disorder mainly includes type 2 diabetes mellitus (T2DM), micro and macro-vascular diseases, non-alcoholic fatty liver disease (NAFLD), dyslipidemia, and the dysfunction of gut microbiota. Strategies and therapeutic attention are demanded to decrease the high risk of metabolic diseases, from lifestyle changes to drug treatment, especially herbal medicines. Indole is a parent substance of numerous bioactive compounds, and itself can be produced by tryptophan catabolism to stimulate glucagon-like peptide-1 (GLP-1) secretion and inhibit the development of obesity. In addition, in heterocycles drug discovery, the indole scaffold is primarily found in natural compounds with versatile biological activity and plays a prominent role in drug molecules synthesis. In recent decades, plenty of natural or synthesized indole deriviatives have been investigated and elucidated to exert effects on regulating glucose hemeostasis and lipd metabolism. The aim of this review is to trace and emphasize the compounds containing indole scaffold that possess immense potency on preventing metabolic disorders, particularly T2DM, obesity and NAFLD, along with the underlying molecular mechanisms, therefore facilitate a better comprehension of their druggability and application in metabolic diseases.

Abstract
Neurodegenerative diseases (NDDs) and cardiovascular diseases (CVDs) are illnesses that affect the nervous system and heart, all of which are vital to the human body. To maintain health of the human body, vegetable diets serve as a preventive approach and particularly Brassica vegetables have been associated with lower risks of chronic diseases, especially NDDs and CVDs. Interestingly, glucosinolates (GLs) and isothiocyanates (ITCs) are phytochemicals that are mostly found in the Cruciferae family and they have been largely documented as antioxidants contributing to both cardio- and neuroprotective effects. The hydrolytic breakdown of GLs into ITCs such as sulforaphane (SFN), phenylethyl ITC (PEITC), moringin (MG), erucin (ER), and allyl ITC (AITC) has been recognized to exert significant effects with regards to cardio- and neuroprotection. From past in vivo and/or in vitro studies, those phytochemicals have displayed the ability to mitigate the adverse effects of reactive oxidation species (ROS), inflammation, and apoptosis, which are the primary causes of CVDs and NDDs. This review focuses on the protective effects of those GL-derived ITCs, featuring their beneficial effects and the mechanisms behind those effects in CVDs and NDDs.

Abstract
Parkinson's disease (PD) is the second most common progressive neurodegenerative disorder. Although mounting studies have been conducted, no effective therapy is available to halt its progression. Indole-3-carbinol (I3C) is a naturally occurring compound obtained by β-thioglucosidase-mediated autolysis of glucobrassicin in cruciferous vegetables. Besides its powerful antioxidant activity, I3C has shown neuroprotection against depression and chemically induced neurotoxicity via its anti-inflammatory and antiapoptotic effects. This study aimed to investigate the neuroprotective effects of I3C against rotenone (ROT)-induced PD in male albino rats. The possible protective mechanisms were also explored. PD was induced by subcutaneous administration of ROT (2 mg/kg) for 28 days. The effects of I3C (25, 50, and 100 mg/kg/day) were assessed by catalepsy test (bar test), spontaneous locomotor activity, rotarod test, weight change, tyrosine hydroxylase (TH) expression, α-synuclein (α-Syn) expression, striatal dopamine (DA) content, and histological examination. The highest dose of I3C (100 mg/kg) was the most effective to prevent ROT-mediated motor dysfunctions and amend striatal DA decrease, weight loss, neurodegeneration, TH expression reduction, and α-Syn expression increase in both the midbrain and striatum. Further mechanistic investigations revealed that the neuroprotective effects of I3C are partially attributed to its anti-inflammatory and antiapoptotic effects and the activation of the sirtuin 1/AMP-activated protein kinase pathway. Altogether, these results suggested that I3C could attenuate biochemical, molecular, and functional changes in a rat PD model with following repeated rotenone exposures.

Abstract
Isothiocyanates, bioactive phytochemicals of cruciferous vegetables, have chemopreventative efficacy. To clarify evidence of associations between cruciferous vegetable and isothiocyanate intake and various health outcomes, we conducted an umbrella review of meta-analyses and systematic reviews in humans. A total of 413 articles were identified, and 57 articles with 24 health outcomes were included. Consumption of cruciferous vegetables was associated with a reduced risk of all-cause mortality, cancers, and depression. Dose-response analyses revealed that a per 100 g/d increment was associated with a 10% decrease in the risk of all-cause mortality. Warfarin resistance caused by vitamin K-rich broccoli was reported. Caution was warranted for those allergies/hypersensitivities to the Brassica genus. The intake of cruciferous vegetables is generally safe and beneficial in humans. However the quality of the majority (68%) of evidence was low.

Abstract
Obesity is one of the most serious public health problems in both developed and developing countries in recent years. While lifestyle and diet modifications are the most important management strategies of obesity, these may be insufficient to ensure long-term weight reduction in certain individuals and alternative strategies including pharmacotherapy need to be considered. However, drugs option remains limited due to low efficacy and adverse effects associated with their use. Hence, identification of safe and effective alternative therapeutic agents remains warranted to combat obesity. In recent years, bioactive phytochemicals are considered as valuable sources for the discovery of new pharmacological agents for the treatment of obesity. Adipocyte hypertrophy and hyperplasia increases with obesity and undergo molecular and cellular alterations that can affect systemic metabolism giving rise to metabolic syndrome and comorbidities such as type 2 diabetes and cardiovascular diseases. Many phytochemicals have been reported to target adipocytes by inhibiting adipogenesis, inducing lipolysis, suppressing the differentiation of preadipocytes to mature adipocytes, reducing energy intake, and boosting energy expenditure mainly in vitro and in animal studies. Nevertheless, further high-quality studies are needed to firmly establish the clinical efficacy of these phytochemicals. This review outlines common pathways involved in adipogenesis and phytochemicals targeting effector molecules of these pathways, the challenges faced and the way forward for the development of phytochemicals as antiobesity agents.

Abstract
An inverse correlation between vegetable consumption and the incidence of cancer has long been described. This protective effect is stronger when cruciferous vegetables are specifically consumed. The beneficial properties of vegetables are attributed to their bioactive components like fiber, antioxidants vitamins, antioxidants, minerals, and phenolic compounds. Cruciferous vegetables contain all these molecules; however, what makes them different are their sulfurous components, called glucosinolates, responsible for their special smell and taste. Glucosinolates are inactive biologically in the organism but are hydrolyzed by the enzyme myrosinase released as a result of chewing, leading to the formation of active derivatives such as isothiocyanates and indoles. A considerable number of in vitro and in vivo studies have reported that isothiocyanates and indoles elicit chemopreventive potency through multiple mechanisms that include modulation of phases I and II detoxification pathway enzymes, regulation of cell cycle arrest, and control of cell growth, induction of apoptosis, antioxidant activity, anti-angiogenic effects, and epigenetic regulation. Nuclear erythroid 2-related factor 2 (Nrf2) and Nuclear factor-κB (NF-κB) are key and central regulators in all these processes with a main role in oxidative stress and inflammation control. It has been described that isothiocyanates and indoles regulate their activity directly and indirectly. Today, the metabolic syndrome (central obesity, insulin resistance, hyperlipidemia, and hypertension) is responsible for a majority of deaths worldwide. All components of metabolic syndrome are characterized by chronic inflammation with deregulation of the PI3K/AKT/mTOR, MAPK/EKR/JNK, Nrf2, and NF-κB signaling pathways. The effects of GLSs derivatives controlling these pathways have been widely described in relation to cancer. Changes in food consumption patterns observed in the last decades to higher consumption of ultra-processed foods, with elevation in simple sugar and saturated fat contents and lower consumption of vegetables and fruits have been directly correlated with metabolic syndrome prevalence. In this review, it is summarized the knowledge regarding the mechanisms by which cruciferous glucosinolate derivatives (isothiocyanates and indoles) directly and indirectly regulate these pathways. However, the review places a special focus on the knowledge of the effects of glucosinolates derivatives in metabolic syndrome, since this has not been reviewed before.

Abstract
Indole-3-carbinol (I3C) is extracted from cruciferous vegetables and is well known for its anti-cancer, antioxidant and anti-inflammatory effects. This study investigated the protective effect of I3C in hyperlipidemia zebrafish larvae and early life stage toxicity of I3C on zebrafish embryos/larvae. Zebrafish larvae were fed with 4% high-cholesterol diet (HCD) and treated with I3C 2.5μmol/L and 5μmol/L for two weeks. Confocal image analysis, oil Red O staining were used to analysis vascular lipid accumulation and western blotting was used to evaluate possible mechanics. In addition, zebrafish embryos were treated with I3C for 96 h to assess the general toxicity and cardiotoxicity. We found that lipid deposition on vasculature was dose-dependently decreased in the I3C treated groups as compared with control group (47%, 23%, p<0.01). Moreover, we demonstrated that I3C inhibited lipid deposition by inducing autophagy, as identified by the enhancement of LC3-II, beclin-1, hVps34 and m-cathepsin D as well as by the reduction of P62, Bcl-2, Akt, p- Akt, mTOR, and p- mTOR in HCD fed zebrafish larvae (p<0.05). In summary, I3C shows protective effects on hyperlipidemia zebrafish larvae and maybe a promising multitarget drug in the prevention and protection against atherosclerotic.

Abstract
BACKGROUND Rheumatoid arthritis (RA) being an incapacitating disease requires early effective intervention. Considering Methotrexate (MTX)- the first line of treatment for RA- intoxicates the liver; therefore, alternative therapies with similar efficacy yet lower cytotoxicity are desired. Indole-3-Carbinol (I3C) which is found in cruciferous vegetables was examined for its possible therapeutic potentials in comparison with MTX by investigating its anti-inflammatory, anti-arthritic, anti-oxidant, and hepatoprotective potentials in adjuvant-induced arthritis (AIA) rat model. METHODS Arthritis was induced in Sprague Dawley rats by injection of Complete Freund's Adjuvant (CFA). Arthritic rats were treated with I3C and/or MTX. To examine the anti-inflammatory and anti-arthritic effect, the following parameters were assessed: body weight, macroscopic scoring of the hind paw, the level of the pivotal cytokines (TNF-α, IL-6) heavily involved in the pathogenesis, spleen index, and erythrocyte sedimentation rate. At a histological level, the tibiotarsal joint was stained with several specific stains. To assess the hepatoprotective and anti-oxidant effects, several oxidative stress parameters were monitored, and the liver histology was examined. RESULTS Both I3C and MTX attenuated the inflammation that was aggravated by arthritis by downregulating the inflammatory markers and mediators and alleviating the histopathological changes affecting the tibiotarsal joint. I3C attenuated the liver impairment that was initiated by arthritis and MTX treatment. It did so by downregulating the pro-oxidants and up-regulating the anti-oxidant defenses and by reducing the pathological changes affecting the liver. CONCLUSION Our results suggest that I3C is as potent as MTX as an anti-inflammatory and anti-arthritic agent. In addition, I3C does so while protecting the liver from damage as opposed to MTX.

Abstract
OBJECTIVE Indole-3-carbinol (I3C), a naturally occurring compound found in cruciferous vegetables, and its metabolite 3,3'-diindolylmethane (DIM) reduce body mass and serum glucose levels in high-fat-diet-induced obese mice. This study aimed to determine whether I3C or DIM could increase glucose uptake via enhanced insulin sensitivity in 3T3-L1 adipocytes, as well as the mechanism involved. METHODS 3T3-L1 preadipocytes were differentiated by using a mixture of adipogenic inducers, including a suboptimal concentration of insulin. RESULTS DIM, but not I3C, increased adipocyte differentiation through upregulation of peroxisome proliferator-activated receptor γ and CCAAT/enhancer-binding protein α. DIM also enhanced glucose uptake by increasing expression of glucose transporter 4 in adipocytes. This was associated with DIM-enhanced phosphorylation of the signaling intermediates Akt, insulin receptor substrate-1, and insulin receptor early in differentiation. CONCLUSIONS Our findings suggest that DIM may improve insulin sensitivity through the activation of the insulin signaling pathway, leading to enhanced glucose uptake.

Abstract
Some natural products, known sources of bioactive compounds with a wide range of properties, may have therapeutic values in human health and diseases, as well as agronomic applications. The effect of three compounds of plant origin with well-known dietary antioxidant properties, astaxanthin (ATX), caffeic acid (CA) and hydroxytyrosol (HT), on zebrafish (Danio rerio) larval adiposity and rainbow trout (Onchorynchus mykiss) adipocytes was assessed. The zebrafish obesogenic test (ZOT) demonstrated the anti-obesogenic activity of CA and HT. These compounds were able to counteract the obesogenic effect produced by the peroxisome proliferator-activated receptor gamma (PPARγ) agonist, rosiglitazone (RGZ). CA and HT suppressed RGZ-increased PPARγ protein expression and lipid accumulation in primary-cultured rainbow trout adipocytes. HT also significantly reduced plasma triacylglycerol concentrations, as well as mRNA levels of the fasn adipogenic gene in the adipose tissue of HT-injected rainbow trout. In conclusion, in vitro and in vivo approaches demonstrated the anti-obesogenic potential of CA and HT on teleost fish models that may be relevant for studying their molecular mode of action. Further studies are required to evaluate the effect of these bioactive components as food supplements for modulating adiposity in farmed fish.

Abstract
3,3'-diindolylmethane is a major in vivo metabolite of indole-3-carbinol, a bioactive compound found in cruciferous vegetables. Although 3,3'-diindolylmethane has been implicated to possess antitumorigenic and anti-inflammatory properties, the effect of 3,3'-diindolylmethane on adipogenesis has not been explored previously. Thus, the present study was conducted to determine if 3,3'-diindolylmethane affects adipogenesis using 3T3-L1 adipocytes and Caenorhabditis elegans. Treatment of 3,3'-diindolylmethane significantly reduced fat accumulation without affecting viability in 3T3-L1 adipocytes. 3,3'-diindolylmethane suppressed expression of peroxisome proliferator-activated receptor γ (PPARγ), CCAAT-enhancer-binding protein α (C/EBPα), fatty acid binding protein 4 (FABP4), and perilipin. In addition, 3,3'-diindolylmethane activated AMP-activated protein kinase α (AMPKα), which subsequently inactivated acetyl CoA carboxylase (ACC), resulting in reduced fat accumulation. These observations were further confirmed in C. elegans as treatment with 3,3'-diindolylmethane significantly reduced body fat accumulation, which was partly associated with aak-1, but not aak-2, orthologs of AMPKα catalytic subunits α1 and α2, respectively. The current results demonstrate that 3,3'-diindolylmethane, a biologically active metabolite of indole-3-carbinol, may prevent adipogenesis through the AMPKα-dependent pathway.

Abstract
Cholecalciferol (CCF) is a common dietary supplement as a precursor of active vitamin D. In the present study, the effect of CCF on lipid accumulation was investigated in adipocyte cells and zebrafish models. CCF effectively inhibited lipid accumulation in both experimental models; this effect was attributed to the CCF-mediated regulation of early adipogenic factors. CCF down-regulated the expressions of CCAAT-enhancer-binding protein-β (C/EBPβ), C/EBPδ, Krueppel-like factor (KLF) 4, and KLF5, while KLF2, a negative adipogenic regulator, was increased by CCF treatment. CCF inhibited cell cycle progression of adipocytes through down-regulation of cyclin A and cyclinD; p-Rb was suppressed by CCF, but p27 was up-regulated with CCF treatment. This CCF-mediated inhibition of cell cycle progression is highly correlated to the inhibitions of extracellular signal-regulated kinase (ERK), serine threonine-specific kinase (AKT), and mammalian target of rapamycin (mTOR). Furthermore, CCF-induced inactivation of acetyl-CoA carboxylase (ACC), a fatty acid synthetic enzyme, with the activation of AMP-activated protein kinase α (AMPKα) was also observed. Consistent with the observations in adipocytes, CCF effectively inhibited lipid accumulation with the down-regulation of adipogenic factors in zebrafish. The present study indicates that CCF showed anti-adipogenic effect in adipocytes and zebrafish, and its inhibitory effect was involved in the regulation of early adipogenic events including cell cycle arrest and activation of AMPKα signaling.

Abstract
OBJECTIVES Aster spathulifolius Maxim (AS), known for its anti-viral and anti-allergic activity, is also known to reduce body weight gain in high fat diet-induced obese rats. But its molecular mechanism of the anti-obesity effects is still unclear. So, we investigated the inhibitory effect of AS extract (ASE) on adipogenesis and lipid accumulation to determine the underlying cellular molecular mechanism. METHODS To perform this study, the contents of intracellular triglyceride were analysed. Real-time polymerase chain reaction and Western blotting were carried out to investigate the expression of adipogenic transcriptional factors. KEY FINDINGS ASE showed the suppression of adipogenic differentiation and the considerable reduction of the lipid accumulation in 3T3-L1 cells. Especially, ASE inhibited the early stage of differentiation via the downregulation of C/EBP-β and C/EBP-δ, which are early adipogenic factors. Major adipogenic factors, such as PPAR-γ and C/EBP-α, were also subsequently inhibited. These findings were supported by Oil Red O staining and intracellular triglyceride levels. A molecular mechanism liking the effect of ASE was identified through the activation of AMPKα pathway. ASE increased protein levels of phosphorylated AMPKα and phosphorylated ACC. CONCLUSIONS ASE showed anti-adipogenic and anti-lipogenic effects through the regulation of adipogenic factors and AMPKα pathway.

Abstract
Silibinin is a compound present mainly in milk thistle. In this study, we investigated the mechanism by which silibinin suppresses adipogenesis of 3T3-L1 cells, and evaluated the anti-adipogenic effect of silibinin in zebrafish. Silibinin reduced lipid accumulation by downregulating adipogenic factors, such as, peroxisome proliferator-activated receptor γ (PPARγ), CCAAT-enhancer binding protein α (C/EBPα), and fatty acid-binding protein 4 (FABP4). The reduction of these adipogenic protein levels was associated with the regulation of early adipogenic factors, such as, C/EBPβ and Krüppel-like factor 2 (KLF2), and was reflected in downregulation of lipid synthetic enzymes. Silibinin arrested cells in the G0/G1 phase of the cell cycle, accompanied by downregulation of cyclins and upregulation of p27, a cell cycle inhibitor. These results correlated with the finding of deactivation of extracellular signal-regulated kinase (ERK) and AKT, a serine/threonine-specific kinase. In addition, silibinin activated AMP-activated protein kinase α (AMPKα) to inhibit fatty acid synthesis. As observed in 3T3-L1 cells, silibinin inhibited lipid accumulation in zebrafish with the reduction of adipogenic factors and triglyceride levels. Our data revealed that silibinin inhibited lipid accumulation in 3T3-L1 cells and zebrafish, and this inhibitory effect was associated with abrogation of early adipogenesis via regulation of cell cycle and AMPKα signaling.
