Abstract
The present study investigated the regulatory effects of β-glucan secreted by Rhizobium pusense (RPG) on triglyceride metabolism and gut microbiota in mice fed a high-fat diet. The results indicated that supplementation with RPG significantly reduced body weight gain, blood glucose levels, and the tissue index of epididymal white adipose tissue (eWAT) and subcutaneous adipose tissue (SAT). Conversely, it increased the tissue index of brown adipose tissue (BAT). Furthermore, RPG supplementation effectively decreased the levels of total cholesterol (TC) and low-density lipoprotein cholesterol (LDL-C) in the serum. Regarding its influence on the triglyceride (TG) mechanism, RPG decreased TG levels in both serum and liver, while elevating TG levels in feces. Moreover, it moderated the composition of gut microbiota in mice fed a high-fat diet, particularly altering functionally relevant intestinal microbial phylotypes, leading to enhanced levels of short-chain fatty acids (SCFAs) in feces. Additionally, RPG treatment regulated the mRNA and protein levels of genes responsible for TG metabolism in the AMPK pathway, indicating an impact on TG synthesis and excretion in the liver. Pearson's correlation network analysis demonstrated strong correlations between key microbial phylotypes responsive to RPG intervention and parameters associated with TG metabolic disorders. SCFA levels were also found to correlate with the mRNA expression levels of genes involved in TG metabolism. Finally, lipidomics analyses were performed to investigate the underlying mechanisms of RPG intervention (glycerophospholipid metabolic pathway) and to identify potential lipid biomarkers, such as TG (18:2/20:4/22:6), TG (18:1/20:4/22:6), TG (20:1/18:1/22:4), PC (17:0/20:4), TG (18:1/20:4/22:5), PC (22:4/22:6), PC (20:0/22:6), PC (20:0e/20:4), DG (18:3e/18:2), DG (10:0/18:2), DG (18:2/14:2), TG (10:0/18:2/20:4), TG (16:1/14:3/18:2) and TG (16:0/14:2/22:6). Overall, our results suggest that RPG could activate the hepatic AMPK signaling pathway by regulating gut microbiota and metabolites through gut-liver crosstalk to exert a lipid-lowering effect in mice fed a high-fat diet and improve obesity.

Abstract
Adipose tissue (AT), composed mainly of adipocytes, plays a critical role in lipid control, metabolism, and energy storage. Once considered metabolically inert, AT is now recognized as a dynamic endocrine organ that regulates food intake, energy homeostasis, insulin sensitivity, thermoregulation, and immune responses. This review examines the multifaceted role of adiponectin, a predominant adipokine released by AT, in glucose and fatty acid metabolism. We explore the regulatory mechanisms of adiponectin, its physiological effects and its potential as a therapeutic target for metabolic diseases such as type 2 diabetes, cardiovascular disease and fatty liver disease. Furthermore, we analyze the impact of various dietary patterns, specific nutrients, and physical activities on adiponectin levels, highlighting strategies to improve metabolic health. Our comprehensive review provides insights into the critical functions of adiponectin and its importance in maintaining systemic metabolic homeostasis.

Abstract
Disruption of brain cholesterol homeostasis has been implicated in neurodegeneration. Nevertheless, the role of cholesterol in Parkinson's Disease (PD) remains unclear. We have used N2a mouse neuroblastoma cells and primary cultures of mouse neurons and 1-methyl-4-phenylpyridinium (MPP+), a known mitochondrial complex I inhibitor and the toxic metabolite of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP), known to trigger a cascade of events associated with PD neuropathological features. Simultaneously, we utilized other mitochondrial toxins, including antimycin A, oligomycin, and carbonyl cyanide chlorophenylhydrazone. MPP+ treatment resulted in elevated levels of total cholesterol and in a Niemann Pick type C1 (NPC1)-like phenotype characterized by accumulation of cholesterol in lysosomes. Interestingly, NPC1 mRNA levels were specifically reduced by MPP+. The decrease in NPC1 levels was also seen in midbrain and striatum from MPTP-treated mice and in primary cultures of neurons treated with MPP+. Together with the MPP+-dependent increase in intracellular cholesterol levels in N2a cells, we observed an increase in 5' adenosine monophosphate-activated protein kinase (AMPK) phosphorylation and a concomitant increase in the phosphorylated levels of mammalian target of rapamycin (mTOR). NPC1 knockout delayed cell death induced by acute mitochondrial damage, suggesting that transient cholesterol accumulation in lysosomes could be a protective mechanism against MPTP/MPP+ insult. Interestingly, we observed a negative correlation between NPC1 protein levels and disease stage, in human PD brain samples. In summary, MPP+ decreases NPC1 levels, elevates lysosomal cholesterol accumulation and alters mTOR signaling, adding to the existing notion that PD may rise from alterations in mitochondrial-lysosomal communication.

Abstract
With population and economic development increasing worldwide, the public is increasingly concerned with the health benefits and nutritional properties of vegetable oils (VOs). In this review, the chemical composition and health-promoting benefits of 39 kinds of VOs were selected and summarized using Web of Science TM as the main bibliographic databases. The characteristic chemical compositions were analyzed from fatty acid composition, tocols, phytosterols, squalene, carotenoids, phenolics, and phospholipids. Health benefits including antioxidant activity, prevention of cardiovascular disease (CVD), anti-inflammatory, anti-obesity, anti-cancer, diabetes treatment, and kidney and liver protection were examined according to the key components in representative VOs. Every type of vegetable oil has shown its own unique chemical composition with significant variation in each key component and thereby illustrated their own specific advantages and health effects. Therefore, different types of VOs can be selected to meet individual needs accordingly. For example, to prevent CVD, more unsaturated fatty acids and phytosterols should be supplied by consuming pomegranate seed oil, flaxseed oil, or rice bran oil, while coconut oil or perilla seed oil have higher contents of total phenolics and might be better choices for diabetics. Several oils such as olive oil, corn oil, cress oil, and rice bran oil were recommended for their abundant nutritional ingredients, but the intake of only one type of vegetable oil might have drawbacks. This review increases the comprehensive understanding of the correlation between health effects and the characteristic composition of VOs, and provides future trends towards their utilization for the general public's nutrition, balanced diet, and as a reference for disease prevention. Nevertheless, some VOs are in the early stages of research and lack enough reliable data and long-term or large consumption information of the effect on the human body, therefore further investigations will be needed for their health benefits.

Abstract
PURPOSE Obesity has become a serious public health problem with its alarmingly increasing prevalence worldwide, prompting researchers to create and develop several anti-obesity drugs. Here, we aimed to investigate the protective effects of perilla seed oil (PSO), sunflower oil (SFO), and tea seed oil (TSO) against obesity through the modulation of the gut microbiota composition and related metabolic changes in mice fed a high-fat diet (HFD). METHODS Mice were divided into six equal groups: ND (normal diet); HFD; ORL (HFD supplemented with 20 mg/kg body weight of orlistat); PSO, SFO, and TSO (HFD supplemented with 2 g/kg body weight of PSO, SFO, and TSO, respectively). RESULTS Our findings showed that PSO, SFO, and TSO supplementation significantly reduced body weight, organ weight, blood glucose, lipopolysaccharides (LPS), insulin resistance, and improved serum lipid levels (TG, TC, LDL-C, and HDL-C). Meanwhile, the three treatments alleviated oxidative stress and hepatic steatosis and reduced liver lipid accumulation. Relative mRNA expression levels of inflammatory cytokines (TNF-α, IL-1β, IL-6, and MCP-1) and lipid synthesis-related genes (PPAR-γ, FAS, and SREBP-1) were down-regulated, while β-oxidation-related genes (PPAR-α, CPT1a, and CPT1b) were up-regulated in the liver tissue of treated mice. Besides, dietary oil supplementation alleviated HFD-induced gut microbiota dysbiosis by promoting gut microbiota richness and diversity, decreasing the Firmicutes-to-Bacteroidetes ratio, and boosting the abundance of some healthy bacteria, like Akkermansia. CONCLUSIONS PSO, SFO, and TSO supplementation could alleviate inflammation, oxidative stress, and hepatic steatosis, likely by modulating the gut microbiota composition in HFD-fed mice.

Abstract
Life expectancy has been on the rise for the past few decades, but healthy life expectancy has not kept pace, leading to a global burden of age-associated disorders. Advancing age is accompanied by a chronic increase in basal systemic inflammation, termed inflammaging, contributing towards an increased risk of developing chronic diseases in old age. This article reviews the recent literature to formulate hypotheses regarding how age-associated inflammaging plays a crucial role in driving chronic diseases and ill health in older adults. Here, we discuss how non-pharmacological intervention strategies (diet, nutraceutical supplements, phytochemicals, physical activity, microbiome-based therapies) targeting inflammaging restore health in older adults. We also consider alternative existing pharmacological interventions (Caloric restriction mimetics, p38 mitogen-activated protein kinase inhibitors) and explore novel targets (senolytics) aimed at combating inflammaging and optimising the ageing process to increase healthy lifespan.

Abstract
The fatty acid composition of coconut oil was modified using enzyme catalyzed interesterification with the aim of obtaining a product more alike to commercial MCT oils. This modification was carried out with the aim to obtain a product with some of the health benefits shown by MCT oils. Initially, lipase B from Candida antarctica immobilized on acrylic resin and lipozyme TL IM were tested as enzyme catalysts for the reaction. The enzyme catalysts have shown similar performance and lipozyme TL IM has been chosen as the catalyst based on its lower cost. The effects of reaction time, oil to methyl octanoate ratio, and enzyme loading on the reaction performance have been investigated with response surface methodology (RSM) utilizing the Box-Behnken approach. The optimized reaction was scaled up to 20 g. The possibility to source the medium chain fatty acid esters from coconut oil fatty acid distillate using a simple procedure was demonstrated and the possibility to use these esters for the interesterification of coconut oil has been demonstrated as well.

Abstract
The obesity epidemic has become a global problem with far-reaching health and economic impact. Despite the numerous therapeutic efficacies of Platycodon grandiflorum, its role in modulating obesity-related metabolic disorders has not been clarified. In this study, a purified neutral polysaccharide, PGNP, was obtained from Platycodon grandiflorum. Based on methylation and NMR analyses, PGNP was found to be composed of 2,1-β-D-Fruf residues ending with a (1→2)-bonded α-D-Glcp. The protective effects of PGNP on high-fat HFD-induced obesity were assessed. According to our results, PGNP effectively alleviated the signs of metabolic syndrome, as demonstrated by reductions in body weight, hepatic steatosis, lipid profile, inflammatory response, and insulin resistance in obese mice. Under PGNP treatment, intestinal histomorphology and the tight junction protein, ZO-1, were well maintained. To elucidate the underlying mechanism, 16S rRNA gene sequencing and LC-MS were employed to assess the positive influence of PGNP on the gut microbiota and metabolites. PGNP effectively increased species diversity of gut microbiota and reversed the HFD-induced imbalance in the gut microbiota by decreasing the Firmicutes to Bacteroidetes ratio. The abundance of Bacteroides and Blautia were increased after PGNP treatment, while the relative abundance of Rikenella, Helicobacter were reduced. Furthermore, PGNP notably influenced the levels of microbial metabolites, including the increased levels of cholic and gamma-linolenic acid. Overall, PGNP might be a potential supplement for the regulation of gut microbiota and metabolites, further affecting obesity.

Abstract
Excessive consumption of fat and sugar is associated with various chronic diseases. However, the variation of fat and sugar content in the diet greatly affected the outcome. In this study, a high-fat, high-fructose diet (HFHFD) formula was made with a composition of 31.99% carbohydrate, 40.7% fat, 11.8% protein, and an additional 30% fructose drink to confirm the effects of HFHFD on metabolic health and pathological changes in organs, especially the liver, kidneys, pancreas, muscles, and spleen. A total of 24 male Wistar rats aged 8–12 weeks were divided into four groups: standard chow (SC), HFHFD, SC + carbon tetrachloride (CCl4), and HFHFD + CCl4. After eight weeks of dietary intervention, body mass index, obesity index, lipid profiles, liver function tests, fasting blood glucose, serum uric acid and urea levels, and tissue histopathology were examined. HFHFD with the main unsaturated fatty acids of linoleic acid (14.57%) and palmitoleic acid (8.28%), the main saturated fatty acids of stearic acid (13.62%) and myristic acid (10.09%), and a low trans-fatty acids content, did not promote the rats to become obese. However, liver histology examination showed severe hepatic steatosis (78.33%), leading to steatohepatitis accompanied by an increase in serum ALP (p < 0.01), triglyceride (p < 0.001), total cholesterol (p < 0.05), and uric acid (p < 0.001) levels. Other histological features showed moderate lesions (45%) of the kidney, slight vacuolization of the pancreas, and a mild increase of inflammatory cells in the spleen and muscle. So, this study found that although HFHFD did not promote obesity within 8 weeks of administration, it induced hepatic and renal lesions, dyslipidemia, and hyperuricemia as a metabolic consequence of excessive fatty acids and fructose.

Abstract
Perilla (Perilla frutescens) oil reduces high-fat-diet-induced colon inflammation by suppressing the NF-κB pathway. In the current study, we compared the effect of endogenously produced and externally supplemented omega-3 fatty acids on high-fat-diet-induced colon inflammation. The fat-1 transgenic mice that endogenously synthesize omega-3 fatty acids were backcrossed with C57BL/6J wild-type mice to obtain transgenic (TR) and wild-type (WT) littermates. Five-week-old male littermates were divided into five groups: two groups fed 10% normal diet (WTLD, TRLD) and three groups fed with a 60% fat high-fat diet (WTHD, TRHD, and WTPO). In the WTPO group, 8% (w/w) of perilla oil was added. Perilla oil supplemented WT mice and fat-1 transgenic mice suppressed high-fat-diet-induced body weight and improved serum lipid levels. Furthermore, the WTPO and TRHD groups exhibited increased colon length, lower macroscopic scores, and reduced levels of pro-inflammatory markers and improved epithelial integrity barrier markers. The expression of GPR120 was increased in the WTPO group. Altogether, our results indicated that perilla oil could improve the symptoms of colon inflammation as an alternate omega-3 fatty acid supplement.

Gut microbiome responses to dietary intervention with hypocholesterolemic vegetable oils. NPJ Biofilms Microbiomes 2022; 8:24. [PMID: 35411007 PMCID: PMC9001705 DOI: 10.1038/s41522-022-00287-y] [Citation(s) in RCA: 10] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/07/2021] [Accepted: 03/10/2022] [Indexed: 12/13/2022] Open
Abstract
Hypercholesterolemia is becoming a problem with increasing significance. Dietary vegetable oils may help to improve this condition due to presence of phytonutrients with potentially synergistic cholesterol-lowering effects. The objective of this 8-week double-blinded randomized clinical trial was to investigate the effects of consuming 30 g of two different blended cooking oils, rich in omega-3 alpha-linolenic acid and phytonutrients, or refined olive oil on the intestinal microbiota in 126 volunteers with borderline hypercholesterolemia. Multi-factor analysis of relationships between the gut microbiota composition at various taxonomic ranks and the clinical trial parameters revealed the association between beneficial effects of the dietary intervention on the blood lipid profile with abundance of Clostridia class of the gut microbiota. This microbiota feature was upregulated in the course of the dietary intervention and associated with various plasma markers of metabolic health status, such as Triglycerides, Apolipoprotein B and Total Cholesterol to HDL ratio in a beneficial way. The relative abundance of a single species—Clostridium leptum—highly increased during the dietary intervention in all the three study groups. The oil blend with the highest concentration of omega-3 PUFA is associated with faster and more robust responses of the intestinal microbiota, including elevation of alpha-diversity. Butyrate production is being discussed as a plausible process mediating the observed beneficial influence on the plasma lipid profile. Causal mediation analysis suggested that Clostridium genus rather than the higher rank of the phylogeny—Clostridia class—may be involved in the diet-induced improvements of the blood lipid profile.

Edward OC, Thomas SS, Cha KO, Jung HA, Han A, Cha YS. Green perilla leaf extract ameliorates long-term oxidative stress induced by a high-fat diet in aging mice. Nutr Res Pract 2022; 16:549-564. [PMID: 36238378 PMCID: PMC9523205 DOI: 10.4162/nrp.2022.16.5.549] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/24/2021] [Revised: 12/15/2021] [Accepted: 03/25/2022] [Indexed: 11/29/2022] Open
Abstract
BACKGROUND/OBJECTIVES Oxidative stress is caused by an imbalance between harmful free radicals and antioxidants. Long-term oxidative stress can lead to an “exhausted” status of antioxidant defense system triggering development of metabolic syndrome and chronic inflammation. Green perilla (Perilla frutescens) is commonly used in Asian cuisines and traditional medicine in southeast Asia. Green perilla possesses numerous beneficial effects including anti-inflammatory and antioxidant functions. To investigate the potentials of green perilla leaf extract (PE) on oxidative stress, we induced oxidative stress by high-fat diet (HFD) in aging mice. MATERIALS/METHODS C57BL/6J male mice were fed HFD continuously for 53 weeks. Then, mice were divided into three groups for 12 weeks: a normal diet fed reference group (NDcon), high-fat diet fed group (HDcon), and high-fat diet PE treated group (HDPE, 400 mg/kg of body weight). Biochemical analyses of serum and liver tissues were performed to assess metabolic and inflammatory damage and oxidative status. Hepatic gene expression of oxidative stress and inflammation related enzymes were evaluated by quantitative real-time polymerase chain reaction (qRT-PCR). RESULTS PE improved hepatopathology. PE also improved the lipid profiles and antioxidant enzymes, including hepatic glutathione peroxidase (GPx) and superoxide dismutase (SOD) and catalase (CAT) in serum and liver. Hepatic gene expressions of antioxidant and anti-inflammatory related enzymes, such as SOD-1, CAT, interleukin 4 (IL-4) and nuclear factor erythroid 2-related factor (Nrf2) were significantly enhanced by PE. PE also reduced the levels of hydrogen peroxide (H2O2) and malondialdehyde (MDA) in the serum and liver; moreover, PE suppressed hepatic gene expression involved in pro-inflammatory response; Cyclooxygenase-2 (COX-2), nitric oxide synthase (NOS), interleukin 1 beta (IL-1β), and interleukin 6 (IL-6). CONCLUSIONS This research opens opportunities for further investigations of PE as a functional food and possible anti-aging agent due to its attenuative effects against oxidative stress, resulting from HFD and aging in the future.

Perilla Seed Oil Alleviates Gut Dysbiosis, Intestinal Inflammation and Metabolic Disturbance in Obese-Insulin-Resistant Rats. Nutrients 2021; 13:nu13093141. [PMID: 34579018 PMCID: PMC8467704 DOI: 10.3390/nu13093141] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/15/2021] [Revised: 09/03/2021] [Accepted: 09/06/2021] [Indexed: 12/13/2022] Open
Abstract
Background: High-fat diet (HFD) consumption induced gut dysbiosis, inflammation, obese-insulin resistance. Perilla seed oil (PSO) is a rich source of omega-3 polyunsaturated fatty acids with health promotional effects. However, the effects of PSO on gut microbiota/inflammation and metabolic disturbance in HFD-induced obesity have not been investigated. Therefore, we aimed to compare the effects of different doses of PSO and metformin on gut microbiota/inflammation, and metabolic parameters in HFD-fed rats. Methods: Thirty-six male Wistar rats were fed either a normal diet or an HFD for 24 weeks. At week 13, HFD-fed rats received either 50, 100, and 500 mg/kg/day of PSO or 300 mg/kg/day metformin for 12 weeks. After 24 weeks, the metabolic parameters, gut microbiota, gut barrier, inflammation, and oxidative stress were determined. Results: HFD-fed rats showed gut dysbiosis, gut barrier disruption with inflammation, increased oxidative stress, metabolic endotoxemia, and insulin resistance. Treatment with PSO and metformin not only effectively attenuated gut dysbiosis, but also improved gut barrier integrity and decreased gut inflammation. PSO also decreased oxidative stress, metabolic endotoxemia, and insulin resistance in HFD-fed rats. Metformin had greater benefits than PSO. Conclusion: PSO and metformin had the beneficial effect on attenuating gut inflammation and metabolic disturbance in obese-insulin resistance.

[PMID: 33849439 PMCID: PMC8042725 DOI: 10.1186/s12870-021-02952-4] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/03/2021] [Accepted: 03/29/2021] [Indexed: 05/06/2023]
Abstract
BACKGROUND Cottonseed is one of the major sources of vegetable oil. Analysis of the dynamic changes of fatty acid components and the genes regulating the composition of fatty acids of cottonseed oil is of great significance for understanding the biological processes underlying biosynthesis of fatty acids and for genetic improving the oil nutritional qualities. RESULTS In this study, we investigated the dynamic relationship of 13 fatty acid components at 12 developmental time points of cottonseed (Gossypium hirsutum L.) and generated cottonseed transcriptome of the 12 time points. At 5-15 day post anthesis (DPA), the contents of polyunsaturated linolenic acid (C18:3n-3) and saturated stearic acid (C18:0) were higher, while linoleic acid (C18:2n-6) was mainly synthesized after 15 DPA. Using 5 DPA as a reference, 15,647 non-redundant differentially expressed genes were identified in 10-60 DPA cottonseed. Co-expression gene network analysis identified six modules containing 3275 genes significantly associated with middle-late seed developmental stages and enriched with genes related to the linoleic acid metabolic pathway and α-linolenic acid metabolism. Genes (Gh_D03G0588 and Gh_A02G1788) encoding stearoyl-ACP desaturase were identified as hub genes and significantly up-regulated at 25 DPA. They seemed to play a decisive role in determining the ratio of saturated fatty acids to unsaturated fatty acids. FAD2 genes (Gh_A13G1850 and Gh_D13G2238) were highly expressed at 25-50 DPA, eventually leading to the high content of C18:2n-6 in cottonseed. The content of C18:3n-3 was significantly decreased from 5 DPA (7.44%) to 25 DPA (0.11%) and correlated with the expression characteristics of Gh_A09G0848 and Gh_D09G0870. CONCLUSIONS These results contribute to our understanding on the relationship between the accumulation pattern of fatty acid components and the expression characteristics of key genes involved in fatty acid biosynthesis during the entire period of cottonseed development.
