Abstract
CONTEXT As living standards have improved and lifestyles have undergone changes, metabolic diseases associated with obesity have become increasingly prevalent. It is well established that sesamin (Ses) (PubChem CID: 72307), the primary lignans in sesame seeds and sesame oil, possess antioxidant and anti-inflammatory effects. OBJECTIVE In this study, a systematic review and meta-analysis of the effects of Ses on animal models of obesity-related diseases was performed to assess their impact on relevant disease parameters. Importantly, this study sought to provide insights for the design of future human clinical studies utilizing Ses as a nutritional supplement or drug. DATA SOURCES This study conducted a comprehensive search in PubMed, Web of Science, Embase, Scopus, and the Cochrane Library, identifying English language articles published from inception to April 2023. DATA EXTRACTION The search incorporated keywords such as "sesamin," "obesity," "non-alcoholic fatty liver disease," "type 2 diabetes mellitus," and "metabolic syndrome." The meta-analysis included 17 articles on non-alcoholic fatty liver disease, type 2 diabetes, and metabolic syndrome. DATA ANALYSIS Overall, the pooled results demonstrated that Ses significantly reduced levels of total serum cholesterol (P = .010), total serum triglycerides (P = .003), alanine transaminase (P = .003), and blood glucose (P < .001), and increased high-density lipoprotein cholesterol levels (P = .012) in animal models of nonalcoholic fatty liver disease. In the type 2 diabetes model, Ses mitigated drug-induced weight loss (P < .001), high-fat-diet-induced weight gain (P < .001), and blood glucose levels (P = .001). In the metabolic syndrome model, Ses was associated with a significant reduction in body weight (P < .001), total serum cholesterol (P < .001), total serum triglycerides (P < .001), blood glucose (P < .001), and alanine transaminase levels (P = .039). CONCLUSION The meta-analysis results of this study suggest that Ses supplementation yields favorable effects in animal models of obesity-related diseases, including hypolipidemic, insulin-lowering, and hypoglycemic abilities, as well as organ protection from oxidative stress and reduced inflammation.

Abstract
Vitiligo, a pigmentary autoimmune disorder, is marked by the selective loss of melanocytes in the skin, leading to the appearance of depigmented patches. The principal pathological mechanism is the melanocyte destruction mediated by CD8+ T cells, modulated by oxidative stress and immune dysregulation. Vitiligo affects both physical health and psychological well-being, diminishing the quality of life. Polyphenols, naturally occurring compounds with diverse pharmacological properties, including antioxidant and anti-inflammatory activities, have demonstrated efficacy in managing various dermatological conditions through multiple pathways. This review provides a comprehensive analysis of vitiligo and the therapeutic potential of natural polyphenolic compounds. We examine the roles of various polyphenols in vitiligo management through antioxidant and immunomodulatory effects, melanogenesis promotion, and apoptosis reduction. The review underscores the need for further investigation into the precise molecular mechanisms of these compounds in vitiligo treatment and the exploration of their combination with current therapies to augment therapeutic outcomes.

Biochem Biophys Res Commun 2024; 708:149815. [PMID: 38531220 DOI: 10.1016/j.bbrc.2024.149815] [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: 02/27/2024] [Revised: 03/18/2024] [Accepted: 03/20/2024] [Indexed: 03/28/2024]
Abstract
Sesamin, a special compound present in sesame and sesame oil, has been reported a role in regulating lipid metabolism, while the underlying mechanisms remain unclear. Autophagy has been reported associated with lipid metabolism and regarded as a key modulator in liver steatosis. The present work aimed to investigate whether sesamin could exert its protective effects against lipid accumulation via modulating autophagy in HepG2 cells stimulated with oleic acid (OA). Cell viability was evaluated using the CCK-8 method, and triglycerides (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein, cholesterol (LDL-C), alanine aminotransferase (ALT), along with aspartate aminotransferase (AST) were assessed by oil red O staining, transmission electron microscopy (TEM), and biochemical kits to investigate the lipid-lowering effects of sesamin. Differentially expressed genes were screened by RNA sequencing and validated using real-time quantitative PCR and Western blot. Autophagy and mitophagy related molecules were analyzed employing TEM, Western blot, and immunofluorescence. The data shows that in HepG2 cells stimulated by OA, sesamin reduces levels of TG, TC, LDL-C, ALT, and AST while elevating HDL-C, alleviates the lipid accumulation and improves fatty acid metabolism through modulating the levels of fat metabolism related genes including PCSK9, FABP1, CD36, and SOX4. Sesamin restores the suppressed autophagy in HepG2 cells caused by OA, which could be blocked by autophagy inhibitors. This indicates that sesamin improves fatty acid metabolism by enhancing autophagy levels, thereby mitigating the intracellular lipid accumulation. Furthermore, sesamin significantly enhances the mitophagy and improves mitochondrial homeostasis via activating the PINK/Parkin pathway. These data suggest that sesamin alleviates the excessive lipid accumulation in HepG2 caused by OA by restoring the impaired mitophagy via the PINK1/Parkin pathway, probably playing a preventive or therapeutic role in hepatic steatosis.

Abstract
Sesamin (Ses) is a natural lignan abundantly present in sesame and sesame oil. Pyroptosis, a newly identified type of pro-inflammatory programmed necrosis, contributes to the development of non-alcoholic steatohepatitis (NASH) when hepatocyte pyroptosis is excessive. In this study, Ses treatment demonstrated an improvement in hepatic damage in mice with high-fat, high-cholesterol diet-induced NASH and palmitate (PA)-treated mouse primary hepatocytes. Notably, we discovered, for the first time, that Ses could alleviate hepatocyte pyroptosis both in vivo and in vitro. Furthermore, treatment with phorbol myristate acetate, a protein kinase Cδ (PKCδ) agonist, increased PKCδ phosphorylation and attenuated the protective effects of Ses against pyroptosis in PA-treated mouse primary hepatocytes. Mechanistically, Ses treatment alleviated hepatocyte pyroptosis in NASH, which was associated with the regulation of the PKCδ/nod-like receptor family CARD domain-containing protein 4/caspase-1 axis. This study introduces a novel concept and target, suggesting the potential use of functional factors in food to alleviate liver damage caused by NASH.

Abstract
Nonalcoholic fatty liver disease (NAFLD) has become an increasingly common disease in Western countries and has become the major cause of liver cirrhosis or hepatocellular carcinoma (HCC) in addition to viral hepatitis in recent decades. Furthermore, studies have shown that NAFLD is inextricably linked to the development of extrahepatic diseases. However, there is currently no effective treatment to cure NAFLD. In addition, in 2020, NAFLD was renamed metabolic dysfunction fatty liver disease (MAFLD) to show that its pathogenesis is closely related to metabolic disorders. Recent studies have reported that the development of MAFLD is inextricably associated with mitochondrial dysfunction in hepatocytes and hepatic stellate cells (HSCs). Simultaneously, mitochondrial stress caused by structural and functional disorders stimulates the occurrence and accumulation of fat and lipo-toxicity in hepatocytes and HSCs. In addition, the interaction between mitochondrial dysfunction and the liver-gut axis has also become a new point during the development of MAFLD. In this review, we summarize the effects of several potential treatment strategies for MAFLD, including antioxidants, reagents, and intestinal microorganisms and metabolites.

Sesamin ameliorates lipotoxicity and lipid accumulation through the activation of the estrogen receptor alpha signaling pathway. Biochem Pharmacol 2023; 216:115768.

Abstract
Nonalcoholic fatty liver disease (NAFLD) has been linked to fat accumulation in the liver and lipid metabolism imbalance. Sesamin, a lignan commonly found in sesame seed oil, possesses antioxidant, anti-inflammatory, and anticancer properties. However, the precise mechanisms by which sesamin prevents hepatic steatosis are not well understood. This study aimed to explore the molecular mechanisms by which sesamin may improve lipid metabolism dysregulation. A in vitro hepatic steatosis model was established by exposing HepG2 cells to palmitate sodium. The results showed that sesamin effectively mitigated lipotoxicity and reduced reactive oxygen species production. Additionally, sesamin suppressed lipid accumulation by regulating key factors involved in lipogenesis and lipolysis, such as fatty acid synthase (FASN), sterol regulatory element-binding protein 1c (SREBP-1c), forkhead box protein O-1, and adipose triglyceride lipase. Molecular docking results indicated that sesamin could bind to estrogen receptor α (ERα) and reduce FASN and SREBP-1c expression via the Ca2+/calmodulin-dependent protein kinase kinase β (CaMKKβ)/AMP-activated protein kinase (AMPK) signaling pathway. Sesamin attenuated palmitate-induced lipotoxicity and regulated hepatic lipid metabolism in HepG2 cells by activating the ERα/CaMKKβ/AMPK signaling pathway. These findings suggest that sesamin can improve lipid metabolism disorders and is a promising candidate for treating hepatic steatosis.

Food Sci Nutr 2023; 11:3729-3757.

Abstract
Inflammation, oxidative stress, obesity, infection, hyperlipidemia, hypertension, and diabetes are the main causes of atherosclerosis, which in the long term lead to hardening of the arteries. In the current study, we reviewed recent findings of the mechanism of sesame and its active compounds of sesamin and sesamolin regulates on atherosclerosis. Sesame can decrease the lipid peroxidation and affect the enzymes, which control the balance of oxidative status in the body. Besides modulating the inflammatory cytokines, sesame regulates the main mediators of the signaling pathways in the process of inflammation, such as prostaglandin E2 (PGE2), nuclear factor kappa light-chain enhancer of activated B cells (NF-kB) and peroxisome proliferator-activated receptor gamma (PPAR-γ). Sesame decreases the growth of different pathogens. It fights against obesity and helps to reduce weight, body mass index (BMI), waist circumference, and lipid count of serum and liver. In addition to lowering fasting blood sugar (FBS), it decreases the hemoglobin A1c (HbA1c) and glucose levels and improves insulin function. With high content of linoleic acid, α-linolenic acid, and total polyunsaturated fatty acid (PUFA), sesame efficiently controls the blood plasma lipids and changes the lipid profile. In the case of hypertension, it maintains the health of endothelium through multiple mechanisms and conserves the response of the arteries to vasodilation. PUFA in sesame suppresses blood clotting and fibrinogen activity. All the mentioned properties combat atherosclerosis and hardening of blood vessels, which are detailed in the present review for sesame.

Abstract
This study explored the effects of sesamin on nonalcoholic steatohepatitis (NASH). High-fat and high-fructose diet-fed mice supplemented with or without sesamin. The results suggested that sesamin-treated mice lost body weight and fat tissue weight, had lower levels of serum metabolic parameters, and insulin resistance was mitigated. Histological examinations showed that sesamin treatment mitigated the progression of hepatic steatosis, and inflammation. In addition, sesamin enhanced hepatic antioxidant capacity, and decreased the activations of hepatic c-jun N-terminal kinase, inhibitor of kappa B kinase α, and insulin receptor substrate 1 as well as hepatic interleukin-6 and tumor necrosis factor-alpha levels. Further experiments indicated that sesamin treatment downregulated GRP78 and phospho-inositol-requiring enzyme 1 (IRE1) expression, and upregulated x-box binding protein 1 (XBP1) expression in hepatic tissue. The aforementioned results suggest that sesamin alleviates obesity-associated NASH, which might be linked to the effect of sesamin on the regulation of the hepatic endoplasmic reticulum stress-IRE1/XBP1 pathway. Thus, sesamin may be a good food functional ingredient in the treatment of obesity-associated NASH.

Abstract
Longan, a popular fruit in Asia, has been used in traditional Chinese medicine to treat several diseases for centuries. Recent studies have indicated that longan byproducts are rich in polyphenols. The aim of this study was to analyze the phenolic composition of longan byproduct polyphenol extracts (LPPE), evaluate their antioxidant activity in vitro, and investigate their regulating effect on lipid metabolism in vivo. The results indicated that the antioxidant activity of LPPE was 231.350 ± 21.640, 252.380 ± 31.150, and 558.220 ± 59.810 (mg Vc/g) as determined by DPPH, ABTS, and FRAP, respectively. UPLC-QqQ-MS/MS analysis indicated that the main compounds in LPPE were gallic acid, proanthocyanidin, epicatechin, and phlorizin. LPPE supplementation prevented the body weight gain and decreased serum and liver lipids in high-fat diet-induced-obese mice. Furthermore, RT-PCR and Western blot analysis indicated that LPPE upregulated the expression of PPARα and LXRα and then regulated their target genes, including FAS, CYP7A1, and CYP27A1, which are involved in lipid homeostasis. Taken together, this study supports the concept that LPPE can be used as a dietary supplement in regulating lipid metabolism.

The wild allotetraploid sesame genome provides novel insights into evolution and lignan biosynthesis. J Adv Res 2022:S2090-1232(22)00233-8. [PMID: 36265763 PMCID: PMC10403651 DOI: 10.1016/j.jare.2022.10.004] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/11/2022] [Revised: 10/03/2022] [Accepted: 10/11/2022] [Indexed: 11/05/2022] Open
Abstract
INTRODUCTION The wild tetraploid sesame (Sesamum schinzianum), an ancestral relative of diploid cultivated sesame, grows in the tropical desert of the African Plateau. As a valuable seed resource, wild sesame has several advantageous traits, such as strong environmental adaptability and an extremely high content of sesamolin in its seeds. High-quality genome assembly is essential for a detailed understanding of genome structure, genome evolution and crop improvement. OBJECTIVES Here, we generated two high-quality chromosome-scale genomes from S. schinzianum and a cultivated diploid elite sesame (Sesamum indicum L.) to investigate the potential genetic basis underlying these traits of wild sesame. METHODS The long-read data from PacBio Sequel II platform and high-throughput chromosome conformation capture (Hi-C) data were used to construct high-quality sesame genome. Then dissecting the molecular mechanisms of sesame evolution and lignan biosynthesis through comparative genomics and transcriptomics. RESULTS We found evidence of divergent evolution that involved differences in the number, sequence and expression level of homologous genes between the two sets of subgenomes from allotetraploids in S. schinzianum, all of which might be driven by subfunctionalization after polyploidization. Furthermore, it was found that a great number of genes involved in the stress response have undergone positive selection and resulted from gene family expansion in the wild sesame genome compared with the cultivated sesame genome, which, overall, is associated with adaptative evolution to the environment. We hypothesized that the sole functional member CYP92B14 (SscC22g35272) could be associated with high content of sesamolin in wild sesame seeds. CONCLUSION This study provides high-quality wild allotetraploid sesame and cultivated sesame genomes, reveals evolutionary features of the allotetraploid genome and provides novel insights into lignan synthesis pathways. Meanwhile, the wild sesame genome will be an important resource to conduct comparative genomic and evolutionary studies and plant improvement programmes.

Abstract
Sesamin is a kind of fat-soluble lignan extracted from sesame seeds or other plants. It has attracted more and more attention because of its extensive pharmacological activities. In this study, we systematically summarized the pharmacological activities of sesamin including antioxidant, anti-inflammatory, anticancer, protection of liver and kidney, prevention of diabetes, hypertension, and atherosclerosis. Studies focus on the abilities of sesamin to attenuate oxidative stress by reducing the levels of ROS and MDA, to inhibit the release of pro-inflammatory cytokines (TNF-α, IL-1β, IL-6, etc.), and to induce apoptosis and autophagy in cancer cells through a variety of signaling pathways such as NF-κB, JNK, p38 MAPK, PI3K/AKT, caspase-3, and p53. By inhibiting the production of ROS, sesamin can also enhance the biological activities of NO in blood vessels, improve endothelial dysfunction and hypertension, and change the process of atherosclerotic lesion formation. In line with this, the various pharmacological properties of sesamin have been discussed in this review so that we can have a deeper understanding of the pharmacological activities of sesamin and clear the future development direction of sesamin.

Abstract
Sesamin, a major lignin mainly found in sesame (Sesamum indicum) oil and sesame seeds, has been demonstrated to possess lipoclasis-promoting, antiobesity, and antidiabetic effects. Irisin is a newly discovered myokine that has attracted great interest as a key target to prevent/treat obesity and its related metabolic diseases. However, the effect and potential mechanism of sesamin on FNDC5/irisin are still vacant. In this study, we showed that sesamin treatment increased FNDC5/irisin activation and regulated SIRT1, PGC-1α, and p-SMAD3/SMAD3 expression in C2C12 cells. By using specific inhibitors and lentivirus in C2C12 cells, we found that the SIRT1/SMAD3 axis plays an important role in sesamin regulated FNDC5/irisin activation. We also found that sesamin treatment activated FNDC5 expression and regulated the SIRT1/SMAD3 signaling axis in mice's skeletal muscle. What is more, by the high-fat diet induced obese model, we further showed that sesamin improved the high-fat diet induced decrease in irisin production and secretion, which results in an improvement of body weight gain and skeletal muscle dysfunction. Our results suggested that sesamin could activate FNDC5 expression and stimulate irisin secretion through the SIRT1 pathway both in vitro and in vivo, which may provide a new strategy for preventing and improving irisin deficiency related diseases.

Abstract
Climate change is shifting agricultural production, which could impact the economic and cultural contexts of the oilseed industry, including sesame. Environmental threats (biotic and abiotic stresses) affect sesame production and thus yield (especially oil content). However, few studies have investigated the genetic enhancement, quality improvement, or the underlying mechanisms of stress tolerance in sesame. This study reveals the challenges faced by farmers/researchers growing sesame crops and the potential genetic and genomic resources for addressing the threats, including: (1) developing sesame varieties that tolerate phyllody, root rot disease, and waterlogging; (2) investigating beneficial agro-morphological traits, such as determinate growth, prostrate habit, and delayed response to seed shattering; (3) using wild relatives of sesame for wide hybridization; and (4) advancing existing strategies to maintain sesame production under changing climatic conditions. Future research programs need to add technologies and develop the best research strategies for economic and sustainable development.

J Food Biochem 2022; 46:e14180. [PMID: 35396857 DOI: 10.1111/jfbc.14180] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/28/2021] [Revised: 03/19/2022] [Accepted: 03/24/2022] [Indexed: 12/17/2022]
Abstract
Non-alcoholic fatty liver disease (NAFLD) can be attributed to the imbalance between lipogenesis and lipidolysis in the liver. Sesame lignans (sesamin, sesamolin, and sesamol) are unique bioactive compounds responsible for the nutritional function of sesame oils. However, the preventive effects of three lignans on oxidative stress and lipid metabolism in steatosis HepG2 cells have not been compared. In this study, we investigated the role of sesamin, sesamolin, and sesamol on hepatic lipid accumulation and explored the underlying mechanism via a well-established cell model. The results showed that 3 μg/ml of lignans could decrease the TG/TC contents and alleviate cellular oxidative stress, with an order of the lipid-lowering effect as sesamol > sesamin > sesamolin. The lignan-activated AMPK and PPAR signaling pathways enhanced gene and protein expressions related to fatty acid oxidation, cholesterol efflux, and catabolism. Meanwhile, treatment of the steatosis HepG2 cells with sesamin, sesamolin, and sesamol reduced lipid synthesis and cholesterol uptake, thus lowering intracellular lipogenesis in the process of NAFLD. Our data suggested that sesame lignans can attenuate oxidative stress and regulate lipid metabolism in liver cells, which may be potential therapeutic agents for treating the NAFLD. PRACTICAL APPLICATIONS: The present work demonstrated that sesame lignans can be used for dietary supplements or functional additives with excellent lipid-lowering effects. Furthermore, this study supplied potential molecular mechanisms involved in NAFLD treatment process, and also provided nutritional guidelines for sesame oil evaluation and selection.

Abstract
The bis-benzodioxole-fibrate hybrids were designed by structural simplification and bioisostere principle. Lipids lowering activity was preliminarily screened by Triton WR 1339 induced hyperlipidemia mice model, in which T3 showed the best hypolipidemia, decreasing plasma triglyceride (TG) and total cholesterol (TC), which were better than sesamin and fenofibrate (FF). T3 was also found to significantly reduce TG, TC and low density lipoprotein cholesterin (LDL-C) both in plasma and liver tissue of high fat diet (HFD) induced hyperlipidemic mice. In addition, T3 showed hepatoprotective activity, which the noteworthy amelioration in liver aminotransferases (AST and ALT) was evaluated and the histopathological observation exhibited that T3 inhibited lipids accumulation in the hepatic and alleviated liver damage. The expression of PPAR-α receptor involved lipids metabolism in liver tissue significantly increased after T3 supplementation. Other potent activity, such as antioxidation and anti-inflammation, was also observed. The molecular docking study revealed that T3 has good affinity activity toward to the active site of PPAR-α receptor. Based on these findings, T3 may serve as an effective hypolipidemic agent with hepatoprotection.

Shi L, Karrar E, Wang X. Sesamol ameliorates hepatic lipid accumulation and oxidative stress in steatosis HepG2 cells via the PPAR signaling pathway. J Food Biochem 2021; 45:e13976. [PMID: 34664288 DOI: 10.1111/jfbc.13976] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2021] [Revised: 09/10/2021] [Accepted: 10/09/2021] [Indexed: 12/28/2022]
Abstract
Non-alcoholic fatty liver disease (NAFLD) is a chronic hepatopathy caused by disordered lipid metabolism in the liver. Sesamol, a phenolic compound derived from sesame oil, has been shown to inhibit obesity, hyperlipidemia, and atherosclerosis in previous investigations. However, the preventive effect of sesamol against hepatic steatosis and oxidative stress in NAFLD has not been well-studied. In this work, sesamol was observed to alleviate lipid accumulation and oxidative stress in high oleic acid (300 μM)/cholesterol (25 μM) induced HepG2 cells, thus indicating that sesamol was involved in regulating hepatic lipid metabolism and oxidative injury. Mechanism studies found that the activated peroxisome proliferator-activated receptors (PPAR) signaling pathway by sesamol intervention up-regulated gene and protein expressions related to fatty acid oxidation and cholesterol efflux and catabolism, thus accelerating lipid consumption and reducing intracellular lipid accumulation in the process of NAFLD. These data suggested that sesamol can effectively ameliorate hepatic steatosis and sesamol riched sesamol oil may be a potential agent for finding therapeutic strategies to treat the NAFLD. PRACTICAL APPLICATIONS: Sesamol and sesamol-rich sesame oil have received much attention due to their performance on hepatic lipid regulation. The results of this study indicate that sesamol treatment could ameliorate hepatic steatosis by inhibiting lipid accumulation and oxidative stress, thus demonstrating that sesamol and sesame oil can be used for functional foods and nutraceutical applications in the future. In addition, the present work provides knowledge of the effects of sesamol on NAFLD and involved mechanisms, and further supplies nutritional guidelines for sesame oil consumption.

Abstract
Non-alcoholic fatty liver disease (NAFLD) is a hepatic condition with multiple pathological features and it currently has no specific treatment or approved drug. Wonderful kolanut widely consumed fresh or cooked has been applied in the treatment of numerous diseases in folk medicine. In this study, we evaluate the therapeutic potentials of hydroethanolic extract of defatted Buccholzia coriacea seeds (HEBCS) in NAFLD model. HEBCS was subjected to liquid chromatography - mass spectrometry, and 30 male BALB/c mice (28 ± 2 g) were allocated to three (3) experimental groups (n = 10/group). Mice in group I were fed chow diet (CD); those in group II, high fat diet (HFD) and group III, HFD and 250 mg/kg HEBCS p.o. daily for six weeks. HEBCS alleviates HFD-induced insulin resistance and high plasma insulin and glucose levels. It further alleviates hepatic steatosis, and alters plasma lipid profile. HEBCS also protected against HFD-induced inflammation, oxidative stress and hepatocellular damage. In conclusion, HEBCS alleviated NAFLD in mice via suppression of insulin resistance, hyperlipidemia, inflammation and oxidative stress. PRACTICAL APPLICATIONS: Bioactive polyphenols and alkaloids were identified in hydroethanolic extract of defatted Buccholzia coriacea seeds (HEBCS). This study projects HEBCS as a potential therapeutic agent in the treatment of NAFLD. NAFLD is a multi-factorial condition and therefore, HEBCS is promising considering its multiple-target actions in the current model of NAFLD. HEBCS alleviates insulin resistance, metabolic dysfunction, steatosis, and inflammation in this model. There is a need to further investigate HEBCS in other models of NAFLD as a lead to future use in clinical studies.

Abstract
HEADINGS ETHNOPHARMACOLOGICAL RELEVANCE Sophora alopecuroides L. is a traditional ethnopharmacological plant, which is widely used in traditional Chinese medicine and Mongolian and Uighur medicine to ameliorate "thirst disease". AIM OF THE STUDY This study aimed to investigate the antidiabetic activities and mechanisms of a flavonoid-rich extract from Sophora alopecuroides L. (SA-FRE) both in vivo and vitro. MATERIALS AND METHODS The main six chemical constituents of SA-FRE were elucidated based on an off-line semi-preparative liquid chromatography nuclear magnetic resonance (LC-NMR) protocol. Myc-GLUT4-mOrange-L6 cell models and mouse model with diabetes induced by high-fat diet combined with STZ injection were respectively adopted to investigate the antidiabetic effects of SA-FRE both in vitro and vivo. RESULTS In vivo, 4-week treatment of SA-FRE ameliorated hyperglycemia, dyslipidemia, and insulin resistance in diabetic mice. Mechanically, SA-FRE regulated PPARα and PPARγ expression in white adipose tissue (WAT) and liver, thereby ameliorating dyslipidemia. Moreover, SA-FRE increased the phosphorylation of PKC and further stimulated the GLUT4 expression in WAT and skeletal muscle, thus increasing the glucose utilization in vivo. In vitro, 50 μg/mL SA-FRE increased GLUT4 translocation to about 1.91-fold and glucose uptake to 1.82-fold in L6-myotubes. SA-FRE treatment increased the GLUT4 expression at both gene and protein levels. Furthermore, only Gö6983, a PKC inhibitor, reversed the SA-FRE-induced GLUT4 translocation and expression at the gene and protein levels. CONCLUSIONS Generally, SA-FRE ameliorated hyperglycemia, dyslipidemia, and insulin resistance partly through activating PKC/GLUT4 pathway and regulating PPARα and PPARγ expression.

Animals (Basel) 2021; 11:468. [PMID: 33578642 PMCID: PMC7916339 DOI: 10.3390/ani11020468] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/12/2021] [Revised: 02/02/2021] [Accepted: 02/08/2021] [Indexed: 01/20/2023] Open
Abstract
Whole sesame seeds (WSS) are rich in both linoleic acid (LA) and lignans. However, their impact on the innate immunity of goats is not well studied. Twenty-four goats were divided into three homogeneous sub-groups; comprise one control (CON) and two treated (WWS5 and WWS10). In the treated groups, WSS were incorporated in the concentrates of the CON at 5 (WSS5) and 10% (WSS10) respectively, by partial substitution of both soybean meal and corn grain. The expression levels of MAPK1, IL6, TRIF, IFNG, TRAF3, and JUND genes in the neutrophils of WSS10 fed goats were reduced significantly compared with the CON. The same was found for the expression levels of IFNG and TRAF3 genes in the neutrophils of WSS5 fed goats. Both treated groups primarily affected the MYD88-independent pathway. The dietary supplementation of goats with WSS might be a good nutritional strategy to improve their innate immunity.

Abstract
Inflammation is associated with the development and progression of various disorders including atherosclerosis, diabetes mellitus and cancer. Sesamin, a fat-soluble lignan derived from Sesamum indicum seeds and oil, has received increased attention due to its wide array of pharmacological properties including its immunomodulatory and anti-inflammatory potential. To date, no review has been conducted to summarize or analyze the immunomodulatory and anti-inflammatory roles of sesamin. Herein, we provide a comprehensive review of experimental findings that were reported with regards to the ability of sesamin to modulate inflammation, cellular and humoral adaptive immune responses and Th1/Th2 paradigm. The potential influence of sesamin on the cytotoxic activity of NK cells against cancer cells is also highlighted. The molecular mechanisms and the signal transduction pathways underlying such effects are underscored. The metabolism, pharmacokinetics, absorption, tissue distribution and bioavailability of sesamin in different species, including humans, are reviewed. Moreover, we propose future preclinical and clinical investigations to further validate the potential preventive and/or therapeutic efficacy of sesamin against various immune-related and inflammatory conditions. We anticipate that sesamin may be employed in future therapeutic regimens to enhance the efficacy of treatment and dampen the adverse effects of synthetic chemical drugs currently used to alleviate immune-related and inflammatory conditions.

Abstract
Sesamin, a major lignin isolated from sesame (Sesamum indicum) seeds and sesame oil, is known to possess antioxidant and anti-inflammatory properties. Several studies have revealed that oxidative stress and inflammation play a major role in a variety of cardiovascular diseases (CVDs). This comprehensive review summarizes the evidence on the effects of sesamin on CVD and its risk factors, principally due to its antioxidant properties. Specifically, this review highlights the mechanisms underlying the anti-hypertensive, anti-atherogenic, anti-thrombotic, anti-diabetic, and anti-obesity, lipolytic effects of sesamin both in vivo and in vitro, and identifies the signaling pathways targeted by sesamin and its metabolites. The data indicates that RAS/MAPK, PI3K/AKT, ERK1/2, p38, p53, IL-6, TNFα, and NF-κB signaling networks are all involved in moderating the various effects of sesamin on CVD and its risk factors. In conclusion, the experimental evidence suggesting that sesamin can reduce CVD risk is convincing. Thus, sesamin can be potentially useful as an adjuvant therapeutic agent to combat CVD and its multitude of risk factors.

Abstract
The present work was designed to assess the modulatory effects of sesame oil (SO) and ascorbic acid (AA) on abamectin (ABM)-induced oxidative stress and altered gene expression of hepatic cytochrome P450 2E1 (CYP-2E1), p38 MAPK, and caspase-3 and cerebral P-glycoprotein (Abcb1a receptor). Male rats were distributed into five groups (6 rats/group), receiving distilled water, ABM 2 mg/kg bwt 1/5 LD50 orally for 5 days, ABM + AA 100 mg/kg bwt orally, ABM + SO 5 ml/kg bwt orally, or ABM + SO + AA at the aforementioned doses. Nineteen compounds were identified in the SO sample by GC-MS analysis, including tetradecane,2,6,10-trimethyl, octadecane, 1-hexadecanol,2-methyl, and octadecane,6-methyl. Abamectin significantly upregulated the hepatic CYP-2E1 expression with excess generation of oxidative radicals, as evident by the significant depletion of reduced glutathione and elevation of malondialdehyde concentration (p ≤ 0.05) in rat liver and brain tissues. Further, ABM significantly increased TNF-α concentration, the expression of caspase-3 and p38 MAPK in the liver, as well as p-glycoprotein and GABA-A receptor in the brain. These results were in line with the observed histopathological changes. Sesame oil and/or AA supplementation alleviated ABM-induced cell damage by modulating all tested parameters. In conclusion, ABM induces oxidative stress and increases the expression of CYP-2E1, caspase-3, and p38 MAPK in the liver, as well as P-gp and GABA-A receptor in the brain. These effects could be ameliorated by SO and AA, alone and in combination, probably due to their anti-oxidant, anti-apoptotic, and gene-regulating activities.

Abstract
The use of foodstuff as natural medicines has already been established through studies demonstrating the pharmacological activities that they exhibit. Knowing the nutritional and pharmacological significance of foods enables the understanding of their role against several diseases. Among the foods that can potentially be considered as medicine, is sesame or Sesamum indicum L., which is part of the Pedaliaceae family and is composed of its lignans such as sesamin, sesamol, sesaminol and sesamolin. Its lignans have been widely studied and are known to possess antiaging, anticancer, antidiabetes, anti-inflammatory and antioxidant properties. Modern chronic diseases, which can transform into clinical diseases, are potential targets of these lignans. The prime example of chronic diseases is rheumatic inflammatory diseases, which affect the support structures and the organs of the body and can also develop into malignancies. In line with this, studies emphasizing the anti-inflammatory and anticancer activities of sesame have been discussed in this review.

Abstract
This study aimed to investigate the hypoglycemic and hypolipidemic activities of polysaccharides from Grifola frondosa (GFP) in diabetic mice induced by high-fat diet (HFD) and streptozotocin (STZ). Results showed that oral administration of GFP markedly reduced the serum levels of fasting blood glucose (FBG), oral glucose tolerance (OGT), cholesterol (TC), triglyceride (TG) and low-density lipoprotein cholesterol (LDL-C), and significantly decreased the hepatic levels of TC, TG and free fatty acids (FFA). Meanwhile, high-dose of GFP supplementation (900 mg/kg day) also showed powerful effects on moderating the composition of intestinal microflora in diabetic mice, especially altering the functionally relevant intestinal microbial phylotypes. Spearman's correlation network analysis revealed that key microbial phylotypes responding to GFP intervention were strongly correlated with the glucose and lipid metabolic disorders associated parameters. Moreover, GFP treatment regulated mRNA expression levels of the genes responsible for hepatic glucose and lipid metabolism. It is noteworthy that GFP treatment markedly increased mRNA expression of cholesterol 7α-hydroxylase (CYP7A1) and bile salt export pump (BSEP), suggesting an enhancement of bile acids (BAs) synthesis and excretion in liver. These findings demonstrated that GFP could prevent hyperglycemia and hyperlipidemia in diabetic mice by altering gut microbiota and regulating hepatic glycolipid metabolism related genes, and therefore could be used as potential functional food ingredients for the prevention or treatment of hyperglycemia and hyperlipidemia.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Qiwei Tiexie capsule (QWTX) is a representative prescription of Tibetan medicine, which is widely used for long-term treatment of chronic liver disease and nonalcoholic fatty liver disease (NAFLD). AIM OF THE STUDY This study explored the effects and mechanism of QWTX on 3T3-L1 adipocytes and NAFLD. MATERIALS AND METHODS The 3T3-L1 preadipocytes and NAFLD rat model were used in the study. In 3T3-L1 cells, the cytotoxicity of QWTX was tested by CKK-8, and glucose uptake and fat acid oxidation were assessed by 2-deoxy-D-[3H] glucose and [1-14C] palmitic acid, respectively. The expression levels of carnitine palmitoyltransferase-1 (CPT-1), liver X receptor α (LXRα), peroxisome proliferator-activated receptor (PPAR) γ, inducible nitric oxide synthase (iNOS), ikappa B α (IκBα), and AKT were determined by PCR and western blot. NAFLD was established by the administration of fat emulsion and sucrose for 9 weeks. The effects of QWTX on lipid metabolism, liver function, and hepatic morphology were observed in NAFLD rats by HE and transmission electron microscope. Serum level of nitric oxide (NO) and fee fatty acid (FFA), superoxide dismutase (SOD) and malondialdehyde (MDA) contents in the liver, as well as the expression levels of Cytochrome P450 2E1 (CYP2E1), NF-κB, monocyte chemoattractant protein 1 (MCP-1), CPT-1, LXRα, PPARα, PPARβ/δ, PPARγ, and iNOS were all detected. RESULTS QWTX showed no cell cytotoxicity in 3T3-L1 preadipocyte cells, and increased the 14CO2 production rate to 4.15, which indicated the reducing the fatty accumulation. In NAFLD, QWTX attenuated liver steatosis, fat vacuoles and inflammation from the HE staining and electron micrograph tests. For the oxidative stress biomarkers, serum FFA level was reduced and serum NO level was enhanced after QWTX treatment. In liver tissue, SOD was decreased and MDA was significantly increased in NAFLD, and both of them were restored by QWTX. NF-κB and CYP2E1 were also upregulated in NAFLD, while downregulated by QWTX. Downregulation of LXRα, PPARγ and iNOS by QWTX were both observed in the 3T3-L1 adipocytes and NAFLD model. CONCLUSIONS QWTX protected the liver injury in differentiated 3T3-L1 adipocytes and NAFLD by regulating the LXRα, PPARγ, and NF-κB-iNOS-NO signal pathways.

Abstract
CONTEXT Acute kidney injury (AKI) is considered a major public health concern in today's world. Sepsis-induced AKI is large as a result of exposure to lipopolysaccharide (LPS) that is the major outer membrane component of Gram-negative bacteria. Sesamin is the main lignan of sesame seeds with multiple protective effects. OBJECTIVE In this research, we tried to demonstrate the protective effect of sesamin pretreatment in LPS-induced mouse model of AKI. METHODS LPS was injected at a single dose of 10 mg/kg (i.p.) and sesamin was given p.o. at doses of 25, 50, or 100 mg/kg, one hour prior to LPS. RESULTS Treatment of LPS-challenged mice with sesamin reduced serum level of creatinine and blood urea nitrogen (BUN) and returned back renal oxidative stress-related parameters including glutathione (GSH), malondialdehyde (MDA), and activity of catalase and superoxide dismutase (SOD). Moreover, sesamin alleviated inappropriate changes of renal nuclear factor-kappaB (NF-κB), toll-like receptor 4 (TLR4), cyclooxygenase-2 (COX2), tumor necrosis factor α (TNFα), interleukin-6, DNA fragmentation (an apoptotic index), and nuclear factor (erythroid-derived 2)-like 2 (Nrf2). In addition, sesamin diminished magnitude of kidney tissue damage due to LPS. CONCLUSION In summary, sesamin could dose-dependently abrogate LPS-induced AKI via attenuation of renal oxidative stress, inflammation, and apoptosis.

Abstract
The aim of the present study was to investigate the effect of black sesame seeds ethanol extract (BSSEE) against nonalcoholic fatty liver disease (NAFLD) in fructose-fed mice. Mice were fed a standard diet without or with 30% fructose in drinking water for 8 consecutive weeks, while mice in three BSSEE tested groups received different doses of BSSEE (0.5, 1, and 2 mL/kg) once a day from the fifth week to the eighth week. Administration of BSSEE dose-dependently exerted antiobesity and protective effect against metabolism disorder in fructose-fed mice. Histological examinations indicated that administration of BSSEE obviously reduced hepatic lipid accumulation. Insulin tolerance test (ITT) and glucose tolerance test (GTT) along with decreases of serum insulin and glucose levels by BSSEE treatment suggested the improvement of body insulin resistance, and administration of 1 and 2 mL/kg BSSEE mitigated liver insulin resistance as the evidence of downregulated expression of phospho-JNK1/2/3, phospho-NF-κB p65, phospho-IRS1, and phospho-IKK alpha/beta, up-regulated XBP1 expression, and reductions of TNF-α and IL-6 levels. In addition, BSSEE treatment ameliorated hepatic oxidative stress through increasing GSH, vitamin C, and Nrf2 levels, decreasing MDA and NO levels, and enhancing SOD, CAT, and GSH-Px activities. These results demonstrated that BSSEE showed protective effects against NAFLD-related metabolic diseases in fructose-fed mice. Therefore, BSSEE may be a potent dietary supplement to ameliorate the diseases.

Abstract
Shiitake (Lentinula edodes) extract, eritadenine, has been shown to reduce cholesterol levels, and its hypocholesterolemic actions are involved in the metabolism of methionine. However, the mechanisms by which eritadenine affects cholesterol metabolism in animals fed a high-fat diet containing different sources of lipids have not yet been elucidated in detail. This study was conducted to investigate the effects of shiitake supplementation on serum lipid concentrations in rats fed a diet including a high amount of a plant oil (HO [high oil] and HOS [high oil with shiitake] groups), animal fat (HF [high fat] and HFS [high fat with shiitake] groups), or MCT- (medium-chain triglyceride-) rich plant oil (HM [high MCT] and HMS [high MCT with shiitake] groups). Rats in the HOS, HFS, and HMS groups were fed shiitake. When rats were fed a diet containing shiitake, serum triglyceride, cholesterol levels, and LCAT (lecithin-cholesterol acyltransferase) activities were lower in rats given MCT-rich plant oil than in those that consumed lard. The lipid type in the diet with shiitake also affected serum cholesterol levels and LCAT activities. The diet containing MCT-rich plant oil showed the greatest rates of decrease in all serum lipid profiles and LCAT activities. These results suggest that shiitake and MCT-rich plant oil work together to reduce lipid profiles and LCAT activity in serum.

Abstract
Schaftoside (SS) is a bioactive compound present in the Herba Desmodii Styracifolii (DS), a herb that has been used to treat cholelithiasis and urolithiasis in Chinese medicine. Whether SS inhibits cholesterol (Ch) gallstone formation has not been investigated. This study examined the effects of oral intake of SS on Ch gallstone formation in C57BL/6 mice fed a lithogenic diet. The rate of gallstone formation was recorded. Levels of Ch, triglycerides (TG) and bile salts (BS) were measured in the bile and serum. Liver histopathology was examined microscopically, and mRNA expression levels of key genes involved in cholesterol and bile metabolism were determined by qPCR. Mice fed SS were protected against gallstone formation, had increased biliary levels of BS, and reduced biliary Ch levels, resulting in a lower Ch saturation index (CSI). In addition, mice fed SS had lower serum TG and Ch levels, increased mRNA expression of liver X receptor α, ATP binding cassette transporter 5/8 (ABCG5/8), and ileal bile acid binding protein (IBABP) in the ileum, and of farnesoid X receptor and bile salt export protein (BSEP) in the liver and ileum. SS also protected against histologically determined liver damage. Overall, these data indicate that SS protects against Ch gallstone formation in mice, and that the effect is mediated by activation of ileal liver X receptor α and hepatic farnesoid X receptor.

Abstract
Peroxisome proliferator activated receptors (PPARs) α, -γ and -β/δ are ligand-activated transcription factors and members of the superfamily of nuclear hormone receptor. These receptors play key roles in maintaining glucose and lipid homeostasis by modulating gene expression. PPARs constitute a recognized druggable target and indeed several classes of drugs used in the treatment of metabolic disease symptoms, such as dyslipidemia (fibrates, e.g. fenofibrate and gemfibrozil) and diabetes (thiazolidinediones, e.g. rosiglitazone and pioglitazone) are ligands for the various PPAR isoforms. More precisely, antidiabetic thiazolidinediones act on PPARγ, while PPARα is the main molecular target of antidyslipidemic fibrates. Over the past few years, our understanding of the mechanism underlying the PPAR modulation of gene expression has greatly increased. This review presents a survey on terrestrial and marine natural products modulating the PPARα system with the objective of highlighting how the incredible chemodiversity of natural products can provide innovative leads for this "hot" target.
