Abstract
Studies have confirmed that yogurt has the activity of regulating blood pressure because it is rich in probiotic-fermented food-derived active peptides. There are also studies on angiotensin-converting enzyme inhibition (ACEI) peptide milk, but the bioactive molecules in it are still unclear. Therefore, in this study, we developed a peanut yogurt with ACEI activity, analyzed 1877 differential peptides and their antihypertensive pathways before and after fermentation using peptidomics, and identified three peptides (FLPYPY, QPPPSPPPFL and APFPEVFGK) with potential antihypertensive activity using molecular docking and chemical synthesis techniques. These results first elucidated the relationship between peanut yogurt peptides and antihypertensive function, demonstrated the benefits of peanut yogurt, and provided a theoretical basis for the application of probiotic fermented plant yogurt in health care.

[PMID: 36781604 DOI: 10.1007/s13105-023-00947-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2022] [Accepted: 01/28/2023] [Indexed: 02/15/2023]
Abstract
Acacetin (ACA), a flavone isolated from Chinese traditional medical herbs, has numerous pharmacological activities. However, little is known about the roles in white fat browning and energy metabolism. In the present study, we investigated whether and how ACA would improve energy metabolism in vivo and in vitro. ACA (20 mg/kg) was intraperitoneally injected to the mice with obesity induced by HFD for 14 consecutive days (in vivo); differentiated 3T3-L1 adipocytes were treated with ACA (20 µmol/L and 40 µmol/L) for 24 h (in vitro). The metabolic profile, lipid accumulation, fat-browning and mitochondrial contents, and so on were respectively detected. The results in vivo showed that ACA significantly reduced the body weight and visceral adipose tissue weight, alleviated the energy metabolism disorder, and enhanced the browning-related protein expressions in adipose tissue of rats. Besides, the data in vitro revealed that ACA significantly reduced the lipid accumulation, induced the expressions of the browning-related proteins and cAMP-dependent protein kinase A (PKA), and increased the mitochondrium contents, especially enhanced the energy metabolism of adipocytes; however, treatment with beta-adrenergic receptor blocker (propranolol, Pro) or adenyl cyclase (AC) inhibitor (SQ22536, SQ) abrogated the ACA-mediated effects. The data demonstrate that ACA alleviates the energy metabolism disorder through the pro-browning effects mediated by the AC-cAMP pathway. The findings would provide the experimental foundation for ACA to prevent and treat obesity and related metabolism disorders.

Interaction of FOXO1 and SUMOylated PPARγ1 induced by hyperlipidemia and hyperglycemia favors vascular endothelial insulin resistance and dysfunction. Vascul Pharmacol 2022; 147:107125. [PMID: 36252777 DOI: 10.1016/j.vph.2022.107125] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/21/2022] [Revised: 09/10/2022] [Accepted: 10/10/2022] [Indexed: 11/06/2022]
Abstract
PPARγ1 and FOXO1 are the key transcription factors that regulate insulin sensitivity. We previously found that a small ubiquitin-related modifier of PPARγ1 at K77 (SUMOylation) favored endothelial insulin resistance (IR) induced by high fat/high glucose (HF/HG) administration. However, whether and how the crosstalk between SUMOylated PPARγ1 and FOXO1 would mediate the development of the endothelial IR and dysfunction remains unclear. Here, we emphasize how PPARγ1-K77 SUMOylation would interact with FOXO1 and participate in the development of the endothelial IR and dysfunction. Our results show that the combination of HF/HG and PPARγ1-K77 SUMOylation exhibits a synergistic deteriorative effect on the endothelial IR and dysfunction, presenting decreased NO levels and elevated ET-1 levels, weakened PI3K/Akt/eNOS signaling, and impaired endothelium-dependent vasodilation function. The further researches reveal that PPARγ1-K77 SUMOylation readily interacts with FOXO1, and FOXO1 occupies the PPAR response element (PPRE) which is supposed to be occupied by PPARγ, thus resulting in the decrease of PPARγ1 transcription activity and the mitigation of the PI3K/Akt signaling. Moreover, the mitigation of the PI3K/Akt signaling promotes in turn the accumulation of FOXO1 in the nucleus where FOXO1 interacts with the SUMOylated PPARγ1, thus exerting a positive feedback effect on IR pathogenesis. The findings uncover a novel association between PPARγ1-K77 SUMOylation and FOXO1, which contributes to our understanding of the pathogenesis of endothelial IR and dysfunction and provides novel pharmacological targets for diabetic angiopathy.

Abstract
Obesity is a global epidemic elevating the risk of various metabolic disorders. As there is a lack of effective drugs to treat obesity, we combined bioinformatics and reverse network pharmacology in this study to identify effective herbs to treat obesity. We identified 1011 differentially expressed genes (DEGs) of adipose tissue after weight loss by analyzing five expression profiles (GSE103766, GSE35411, GSE112307, GSE43471, and GSE35710) from the Gene Expression Omnibus (GEO) database. We identified 27 hub genes from the protein-protein interaction (PPI) network by performing MCODE using the Search Tool for the Retrieval of Interacting Genes (STRING) database. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses revealed that these hub genes have roles in the extracellular matrix-receptor interaction, cholesterol metabolism, PI3K-Akt signaling pathway, etc. Ten herbs (Aloe, Portulacae Herba, Mori Follum, Silybum Marianum, Phyllanthi Fructus, Pollen Typhae, Ginkgo Semen, Leonuri Herba, Eriobotryae Folium, and Litseae Fructus) targeting the nine hub genes (COL1A1, MMP2, MMP9, SPP1, DNMT3B, MMP7, CETP, COL1A2, and MUC1) using six ingredients were identified as the key herbs. Quercetin and (-)-epigallocatechin-3-gallate were determined to be the key ingredients. Lastly, Ingredients-Targets, Herbs-Ingredients-Targets, and Herbs-Taste-Meridian Tropism networks were constructed using Cytoscape to elucidate this complex relationship. This study could help identify promising therapeutic targets and drugs to treat obesity.

Abstract
Peroxisome proliferator-activated receptors (PPARs) are members of the ligand-dependent nuclear receptor family. PPARs have attracted wide attention as pharmacologic mediators to manage multiple diseases and their underlying signaling targets. They mediate a broad range of specific biological activities and multiple organ toxicity, including cellular differentiation, metabolic syndrome, cancer, atherosclerosis, neurodegeneration, cardiovascular diseases, and inflammation related to their up/downstream signaling pathways. Consequently, several types of selective PPAR ligands, such as fibrates and thiazolidinediones (TZDs), have been approved as their pharmacological agonists. Despite these advances, the use of PPAR agonists is known to cause adverse effects in various systems. Conversely, some naturally occurring PPAR agonists, including polyunsaturated fatty acids and natural endogenous PPAR agonists curcumin and resveratrol, have been introduced as safe agonists as a result of their clinical evidence or preclinical experiments. This review focuses on research on plant-derived active ingredients (natural phytochemicals) as potential safe and promising PPAR agonists. Moreover, it provides a comprehensive review and critique of the role of phytochemicals in PPARs-related diseases and provides an understanding of phytochemical-mediated PPAR-dependent and -independent cascades. The findings of this research will help to define the functions of phytochemicals as potent PPAR pharmacological agonists in underlying disease mechanisms and their related complications.

Abstract
Literature evidence reveals that natural compounds are potential candidates for ameliorating obesity-associated non-alcoholic fatty liver disease (NAFLD) by targeting forkhead box O1 (FOXO1) transcription factor. FOXO1 has a dual and complex role in regulating both increase and decrease in lipid accumulation in hepatocytes and adipose tissues (AT) at different stages of NAFLD. In insulin resistance (IR), it is constitutively expressed, resulting in increased hepatic glucose output and lipid metabolism irregularity. The studies on different phytochemicals indicate that dysregulation of FOXO1 causes disturbance in cellular nutrients homeostasis, and the natural entities have an enduring impact on the mitigation of these abnormalities. The current review communicates and evaluates certain phytochemicals through different search engines, targeting FOXO1 and its downstream cellular pathways to find lead compounds as potential therapeutic agents for treating NAFLD and related metabolic disorders. The findings of this review confirm that polyphenols, flavonoids, alkaloids, terpenoids, and anthocyanins are capable of modulating FOXO1 and associated signaling pathways, and they are potential therapeutic agents for NAFLD and related complications. HIGHLIGHTS: • FOXO1 has the potential to be targeted by novel drugs from natural sources for the treatment of NAFLD and obesity. • FOXO1 regulates cellular autophagy, inflammation, oxidative stress, and lipogenesis through alternative mechanisms. • Phytochemicals treat NAFLD by acting on FOXO1 or SREBP1c and PPARγ transcription factor signaling pathways.

Abstract
Circadian rhythm is an intrinsic mechanism developed by organisms to adapt to external environmental signals. Nowadays, owing to the job and after-work entertainment, staying up late - Circadian rhythm disorders (CRD) are common. CRD is linked to the development of fatty liver, type 2 diabetes, and chronic gastroenteritis, which affecting the body's metabolic and inflammatory responses via multi-organ crosstalk (gut-liver-brain axis, etc.). However, studies on the mechanisms of multi-organ interactions by CRD are still weak. Current studies on therapeutic agents for CRD remain inadequate, and phytochemicals have been shown to alleviate CRD-induced syndromes that may be used for CRD-therapy in the future. Tea, a popular phytochemical-rich beverage, reduces glucolipid metabolism and inflammation. But it is immature and unclear in the mechanisms of alleviation of CRD-mediated syndrome. Here, we have analyzed the threat of CRD to hosts and their offspring' health from the perspective of the "gut-liver-brain" axis. The potential mechanisms of tea in alleviating CRD were further explored. It might be by interfering with bile acid metabolism, tryptophan metabolism, and G protein-coupled receptors, with FXR, AHR, and GPCR as potential targets. We hope to provide new perspectives on the role of tea in the prevention and mitigation of CRD.HighlightsThe review highlights the health challenges of CRD via the gut-liver-brain axis.CRD research should focus on the health effects on healthy models and its offspring.Tea may prevent CRD by regulating bile acid, tryptophan, and GPCR.Potential targets for tea prevention and mitigation of CRD include FXR, AHR and GPCR.A comprehensive assessment mechanism for tea in improving CRD should be established.

Abstract
Rhubarb as an herbal medicine has been shown to exhibit antiadipogenic activity. This study evaluated and compared the lipid-lowering activity of five rhubarb hydroxyanthraquinones (HAQs), including chrysophanol, aloe emodin, emodin, physcion, and rhein, aiming to identify candidate compounds for obesity treatment. Examination of the antiobesity effects of HAQs in 3T3-L1 adipocytes and high-fat diet (HFD)-induced obese rats showed that these anthraquinone compounds inhibited lipid accumulation in 3T3-L1 cells before and after differentiation. Emodin and rhein showed greater inhibition than the other compounds; dosage at 50 μM reduced intracellular triglyceride (TG) by about 30% in the differentiated adipocytes. Both compounds also revealed lipolytic effects to increase glycerol release from adipocytes. Adipokine overexpression induced by differentiation was downregulated by emodin and rhein through mitogen-activated protein kinase (MAPK) signaling. Despite their structural similarity, emodin and rhein exhibited different mechanisms on adipogenesis and lipid metabolism. Rhein restrained lipid deposition by controlling adipogenic transcriptional factors and lipolytic lipases during differentiation. The lipid-lowering effects of emodin did not use these pathways but reduced levels of lipogenic enzymes. HFD consumption in rats significantly increased body weight, visceral fat mass and adipocyte size, which were attenuated by intraperitoneal delivery of emodin or rhein. Rhein showed greater amelioration of obesity than emodin, decreasing plasma cholesterol by 29% and 14%, respectively. HAQs also suppressed cytokine upregulation in the liver and adipose tissues of obese rats. Rhein is a potential antiobesity agent through its ability to regulate obesity-associated adipogenesis, lipolysis and inflammation.

Mol Cell 2021; 81:4622-4634.e8.

Abstract
AKT is a serine/threonine kinase that plays an important role in metabolism, cell growth, and cytoskeletal dynamics. AKT is activated by two kinases, PDK1 and mTORC2. Although the regulation of PDK1 is well understood, the mechanism that controls mTORC2 is unknown. Here, by investigating insulin receptor signaling in human cells and biochemical reconstitution, we found that insulin induces the activation of mTORC2 toward AKT by assembling a supercomplex with KRAS4B and RHOA GTPases, termed KARATE (KRAS4B-RHOA-mTORC2 Ensemble). Insulin-induced KARATE assembly is controlled via phosphorylation of GTP-bound KRAS4B at S181 and GDP-bound RHOA at S188 by protein kinase A. By developing a KARATE inhibitor, we demonstrate that KRAS4B-RHOA interaction drives KARATE formation. In adipocytes, KARATE controls insulin-dependent translocation of the glucose transporter GLUT4 to the plasma membrane for glucose uptake. Thus, our work reveals a fundamental mechanism that activates mTORC2 toward AKT in insulin-regulated glucose homeostasis.

Borah AK, Sharma P, Singh A, Kalita KJ, Saha S, Chandra Borah J. Adipose and non-adipose perspectives of plant derived natural compounds for mitigation of obesity. JOURNAL OF ETHNOPHARMACOLOGY 2021; 280:114410. [PMID: 34273447 DOI: 10.1016/j.jep.2021.114410] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/09/2021] [Revised: 07/07/2021] [Accepted: 07/10/2021] [Indexed: 06/13/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Phyto-preparations and phyto-compounds, by their natural origin, easy availability, cost-effectiveness, and fruitful traditional uses based on accumulated experiences, have been extensively explored to mitigate the global burden of obesity. AIM OF THIS REVIEW The review aimed to analyse and critically summarize the prospect of future anti-obesity drug leads from the extant array of phytochemicals for mitigation of obesity, using adipose related targets (adipocyte formation, lipid metabolism, and thermogenesis) and non-adipose targets (hepatic lipid metabolism, appetite, satiety, and pancreatic lipase activity). Phytochemicals as inhibitors of adipocyte differentiation, modulators of lipid metabolism, and thermogenic activators of adipocytes are specifically discussed with their non-adipose anti-obesogenic targets. MATERIALS AND METHODS PubMed, Google Scholar, Scopus, and SciFinder were accessed to collect data on traditional medicinal plants, compounds derived from plants, their reported anti-obesity mechanisms, and therapeutic targets. The taxonomically accepted name of each plant in this review has been vetted from "The Plant List" (www.theplantlist.org) or MPNS (http://mpns.kew.org). RESULTS Available knowledge of a large number of phytochemicals, across a range of adipose and non-adipose targets, has been critically analysed and delineated by graphical and tabular depictions, towards mitigation of obesity. Neuro-endocrinal modulation in non-adipose targets brought into sharp dual focus, both non-adipose and adipose targets as the future of anti-obesity research. Numerous phytochemicals (Berberine, Xanthohumol, Ursolic acid, Guggulsterone, Tannic acid, etc.) have been found to be effectively reducing weight through lowered adipocyte formation, increased lipolysis, decreased lipogenesis, and enhanced thermogenesis. They have been affirmed as potential anti-obesity drugs of future because of their effectiveness yet having no threat to adipose or systemic insulin sensitivity. CONCLUSION Due to high molecular diversity and a greater ratio of benefit to risk, plant derived compounds hold high therapeutic potential to tackle obesity and associated risks. This review has been able to generate fresh perspectives on the anti-diabetic/anti-hyperglycemic/anti-obesity effect of phytochemicals. It has also brought into the focus that many phytochemicals demonstrating in vitro anti-obesogenic effects are yet to undergo in vivo investigation which could lead to potential phyto-molecules for dedicated anti-obesity action.

Abstract
The present study aimed to investigate the function and mechanisms of PAR2 in preadipocyte differentiation. This study found that the expression level of PAR2 was increased during 3T3-L1 mouse preadipocyte differentiation towards adipocytes. In addition, PAR2 overexpression significantly stimulated the expression of adipogenic proteins including ACC1, PPARγ, and SREBF1. Moreover, PAR2 overexpression increased the content of triglyceride (TG) in 3T3-L1 preadipocytes. Knockdown of PAR2 suppressed 3T3-L1 preadipocyte differentiation and adipogenesis. Mechanistically, PAR2 promoted 3T3-L1 preadipocyte differentiation and TG production through activation of the PI3K/AKT signalling pathway and MAT2A gene expression. The research sheds light on the adipogenic effects of PAR2 and its underlying mechanisms. Thus, PAR2 may have therapeutic significance for obesity.

Abstract
In the present study, we isolated a lignan ((-)-(2R,3R)-1,4-O-diferuloylsecoisolariciresinol, DFS) from Alnus japonica and evaluated its antiobesity potential in vitro. We also determined its mechanism of action in a mouse pre-adipocyte 3T3-L1 cell line. DFS dose- and day-dependently inhibited adipogenesis by downregulation of adipogenic factors and lipid metabolism-regulating factors during adipocyte differentiation. In particular, DFS suppressed cell cycle-regulating factors and induced G0/G1 cell cycle arrest, implying that it had an inhibitory effect on mitotic clonal expansion which occurred at an early stage of adipogenesis. DFS also suppressed adipogenesis through decreasing Akt phosphorylation and increasing the level of Forkhead box protein-O1 (FOXO1). These results suggest that DFS may be a pharmacological candidate for the development of antiobesity, therapeutic, and nutraceutical products.

Triiodothyronine activated extranuclear pathways upregulate adiponectin and leptin in murine adipocytes. Mol Cell Endocrinol 2020; 503:110690.

Abstract
Adiponectin and leptin, important for metabolic regulation, are synthesized and secreted by adipose tissue and are influenced by triiodothyronine (T3) that activates the MAPK/ERK and integrin αVβ3 pathways, modulating gene expression. Adipocytes were treated with T3 (10 nM), for 1 h, in the absence or presence of PD98059 (PD) and tetraiodothyroacetic acid (Tetrac), which are pathways inhibitors. The cells were incubated with Adipo Red/Oil Red O reagents, and intracellular lipid accumulation [glycerol and triacylglycerol (TAG)], MTT, 8-hydroxideoxyguanosine (8-OH-dG), and mRNA and protein expression were assessed. T3 increased leptin mRNA and protein expression, and, in contrast, there was a decrease in the Tetrac + T3 group. Adiponectin mRNA expression was not altered by T3, though it had increased its protein expression, which was terminated by inhibitors PD + T3 and Tetrac + T3. However, T3 did not alter PPARγ protein expression, lipid accumulation, TAG, glycerol, and DNA damage, but PD + T3 and Tetrac + T3 reduced these parameters. T3 activated the MAPK/ERK pathway on adipocytes to modulate the adiponectin protein expression and integrin αvβ3 to alter the leptin gene expression.

Abstract
BACKGROUND Injection of adipose-derived stem cells (ASCs) is a promising treatment for facial contour deformities. However, its treatment mechanisms remain largely unknown. The study aimed to explain the molecular mechanisms of adipogenic differentiation from ASCs based on the roles of long noncoding RNAs (lncRNAs). METHODS Datasets of mRNA-lncRNA (GSE113253) and miRNA (GSE72429) expression profiling were collected from Gene Expression Omnibus database. The differentially expressed genes (DEGs), lncRNAs (DELs) and miRNAs (DEMs) between undifferentiated and adipocyte differentiated human ASCs were identified using the Linear Models for Microarray Data method. DELs related co-expression and competing endogenous RNA (ceRNA) networks were constructed. Protein-protein interaction (PPI) analysis was performed to screen crucial target genes. RESULTS A total of 748 DEGs, 17 DELs and 51 DEMs were identified. A total of 13 DELs and 279 DEGs with Pearson correlation coefficients > 0.9 and p-value < 0.01 were selected to construct the co-expression network. A total of 151 interaction pairs among 112 nodes (10 DEMs; eight DELs; 94 DEGs) were obtained to construct the ceRNA network. By comparing the lncRNAs and mRNAs in two networks, five lncRNAs (SNHG9, LINC02202, UBAC2-AS1, PTCSC3 and myocardial infarction associated transcript (MIAT)) and 32 genes (i.e., such as phosphoinositide-3-kinase regulatory subunit 1 (PIK3R1), protein tyrosine phosphatase receptor type B (PTPRB)) were found to be shared. PPI analysis demonstrated PIK3R1 , forkhead box O1 (FOXO1; a transcription factor) and estrogen receptor 1 (ESR1) were hub genes, which could be regulated by the miRNAs that interacted with the above five lncRNAs, such as LINC02202-miR-136-5p-PIK3R1, LINC02202-miR-381-3p-FOXO1 and MIAT-miR-18a-5p-ESR1. LINC02202 also could directly co-express with PIK3R1. Furthermore, PTPRB was predicted to be modulated by co-expression with LINC01119. CONCLUSION MIAT, LINC02202 and LINC01119 may be potentially important, new lncRNAs associated with adipogenic differentiation of ASCs. They may be involved in adipogenesis by acting as a ceRNA or co-expressing with their targets.

Abstract
Forkhead box-O1 (FOXO1) is a downstream target of AKT and plays crucial roles in cell cycle control, apoptosis, metabolism and adipocyte differentiation. It is thought that FOXO1 affects adipocyte differentiation by regulating lipogenesis and cell cycle. With the deepening in the understanding of this field, it is currently believed that FOXO1 translocation between nuclei and cytoplasm is involved in the regulation of FOXO1 activity, thus affecting adipocyte differentiation. Translocation of FOXO1 depends on its post-translational modifications and interactions with 14-3-3. Based on these modifications and interactions, FOXO1 could regulate lipogenesis through PPARγ and the adipocyte cell cycle through p21 and p27. In this review, we aim to provide a comprehensive FOXO1 regulation network in adipocyte differentiation by linking together distinct functions mentioned above to explain their effects on adipocyte differentiation and to emphasize the regulatory role of FOXO1. In addition, we also focus on the novel findings such as the use of miRNAs in FOXO1 regulation and highlight the improvable issues, such as RNA modifications, for future research in the field.
