[PMID: 39241999 DOI: 10.1016/j.ijbiomac.2024.135223] [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: 03/28/2024] [Revised: 08/05/2024] [Accepted: 08/29/2024] [Indexed: 09/09/2024]
Abstract
Laminaria digitata is a high-quality seaweed resource that is widely cultured and has good application prospects. In this study, Laminaria digitata fucoidan (LF) was extracted from Laminaria digitata, and purified using DEAE-Sepharose Fast Flow gel column to obtain four different grades. Among those, LF4 (Mw:165 kDa), mainly composed of fucose(56.80 %), had the highest total sugar (66.91 %) and sulfate (17.07 %) content. FT-RT and NMR results showed that LF4 was mainly composed of galactosylated galactofucose, and has a sulfate group attached to fucose C4. With the animal experimentation, it was revealed that hyperlipidaemic mice had significantly higher levels of TC (5.52 mmol/L), TG (2.28 mmol/L) and LDL-C (5.12 mmol/L) and significantly lower levels of HDL-C (2 mmol/L). However, LF had the efficacy in modulating the lipid metabolism disturbances induced by hyperlipidemia, as well as the ability to regulate cholesterol transport in serum. Moreover, it regulated AMPK/ACC, PPAR-α/LAXRa, Nrf2/Nqo1, TLR4/NF-κB signaling pathway genes and proteins expression in the liver. In addition, it promoted the production of beneficial short-chain fatty acids (SCFAs) while improving the composition and structure of gut microbiota, including balancing the abundance of Bacteroidota, Firmicutes, Muribaculaceae, Alloprevotella, Escherichia-Shigella, Prevotella and NK4A136. The results clearly indicated that LF4 could significantly ameliorate hyperlipidemia, suggesting its prospective application as a functional food.

Flavonoids from mulberry leaves inhibit fat production and improve fatty acid distribution in adipose tissue in finishing pigs. ANIMAL NUTRITION (ZHONGGUO XU MU SHOU YI XUE HUI) 2024; 16:147-157. [PMID: 38357574 PMCID: PMC10864206 DOI: 10.1016/j.aninu.2023.11.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/15/2023] [Revised: 11/05/2023] [Accepted: 11/23/2023] [Indexed: 02/16/2024]
Abstract
This study evaluated the effects of flavonoids from mulberry leaves (FML) on plasma biochemical indices, serum activities of lipid metabolism-related enzymes, fat morphology, fatty acid composition, and lipid metabolism in different adipose tissues of finishing pigs. We used 120 Chinese hybrid barrows of Berkshire and Bama mini-pigs with an average initial body weight of 45.11 ± 4.23 kg. The pigs were randomly assigned to five treatment groups and fed a control diet based on corn, soybean meal, and wheat bran or a control diet supplemented with 0.02%, 0.04%, 0.08%, or 0.16% FML. Each experimental group had six replicates (pens), with four pigs per pen. After a 7-d adaptation period, the feeding trial was conducted for 58 d. Blood and adipose tissue samples were collected from 30 pigs (one pig per pen) at the end of the test. The results showed that FML supplementation significantly decreased the feed intake to body gain ratio, the plasma concentrations of total cholesterol and free fatty acids, and the serum activity of 3-hydroxy-3-methylglutaryl coenzyme A reductase (linear or quadratic effects, P < 0.05), and decreased the plasma triglyceride concentration (quadratic, P = 0.07). Increasing FML supplementation increased the average daily gain and serum activities of lipoprotein lipase (linear and quadratic effects, P < 0.05) and adipose triglyceride lipase (linear, P < 0.05). Dietary FML supplementation decreased the adipocyte area in the dorsal subcutaneous adipose (DSA) tissue of finishing pigs (linear, P = 0.05) and increased the adipocyte area in the visceral adipose tissue (quadratic, P < 0.01). Increasing FML supplementation decreased the C20:1 content in DSA, abdominal subcutaneous adipose, and visceral adipose tissues of finishing pigs (P < 0.05) and increased the C18:3n3 and n-3 PUFA contents (P < 0.05). The lipid metabolism genes were regulated by the PPARγ-LXRα-ABCA1 signaling pathway, and their expressions differed in different adipose tissues. These findings suggest that FML improved growth performance, regulated lipid metabolism, inhibited fat production, and improved fatty acid distribution in the adipose tissue of finishing pigs, thereby improving pig fat's nutritional quality and health value.

Abstract
This study evaluated the effects of supplementation with Antrodia cinnamomea mycelium by-product (ACBP) on growth performance and immune response in weaning piglets. Total available content and antioxidant capacity of ACBP were determined. Ninety-six black pigs were randomly distributed to 24 pens. Study compared four groups which were supplemented with ACBP at 0%, 2.5%, 5%, or 10% for 6 weeks after weaning at 4 weeks. Results showed that ACBP on total phenolic, total flavonoid, and total triterpenoids contents were 13.68 mg GAE/g DW, 1.67 μg QE/g DW, and 15.6 mg/g, respectively. Weaning piglets fed 2.5% ACBP showed a significant decreased body weight gain compared with those supplemented with 5% ACBP, 10% ACBP, and control groups. Results showed that all ACBP groups increased the villi height of jejunum significantly. Incidence of diarrhea in 11 weeks with supplementation with 5% and 10% ACBP diets were lower than in control group. The 10% ACBP group showed significantly lower expression of immune response genes (IL-1β, IL-6, IL-8, TNF-α, and IFN-γ) than the 2.5% and 5% ACBP groups. Based on results, dietary supplementation with 10% ACBP did not significantly affect body weight but could decrease piglet diarrhea condition and expression of IL-1β and IL-6 genes.

Abstract
Oudemansiella raphanipies, also called “Edible Queen,” is a mushroom that possesses antioxidant, anti-inflammatory, anti-bacterial, anti-tumor and immunity-enhancing properties. The present study aimed to assess the effect of O. raphanipies-derived polysaccharide (ORPS) on the progression of nonalcoholic fatty liver disease (NAFLD) in mice. We studied the structure of ORPS-1 by high-performance gel permeation chromatography (HPGPC), ion chromatography-mass spectrometry (GC-MS), and Fourier transform-infrared spectroscopy (FT-IR). ORPS-1 mainly comprised galactose, fucose, glucose, mannose, and xylose, following an 18:6:6:4:1 molar ratio. In addition, the therapeutic effect as well as a potential mechanism of ORPS-1 in the treatment of high-fat diet (HFD)-induced NAFLD were investigated. The results showed that ORPS-1 improved liver function, ameliorated liver steatosis, and reduced lipid droplet accumulation in HFD mice. A metabolomics approach with GC-MS was utilized to evaluate liver improvement by ORPS-1 treatment. Principal component analysis showed that liver metabolic profiling was significantly altered by HFD feeding or treatment with an intermediate dose of ORPS-1 in mice compared with that of control mice. By investigating the metabolic pathways with identified biomarkers, various pathways such as steroid biosynthesis, valine, leucine, and isoleucine biosynthesis, glycerol phospholipid metabolism, glyceride metabolism, and arginine and proline metabolism in HFD mice were observed to be significantly influenced by ORPS-1 treatment. The results indicate ORPS-1 metabolic effects on liver tissues, provide methods for assessing the molecular impact of ORPS-1 on NAFLD, and suggest the potential mechanism underlying its health benefits.

Abstract
Objective. This study aimed to determine the active ingredients of Huanglian Jiedu decoction (HLJDD) and the targets for treating dyslipidemia through network pharmacology to facilitate further application of HJJDD in the treatment of dyslipidemia. Methods. Potential drug targets for dyslipidemia were identified with a protein-protein interaction network. Gene ontology (GO) enrichment analysis and KEGG pathway analysis were performed to elucidate the biological function and major pathways involved in the HLJDD-mediated treatment of dyslipidemia. Results. This approach revealed 22 components, 234 targets of HLJDD, and 221 targets of dyslipidemia. There were 14 components and 31 common targets between HLJDD and dyslipidemia treatment. GO enrichment analysis showed that these targets were mainly associated with the response to DNA-binding transcription factor activity, lipid localization and storage, reactive oxygen species metabolic process, and inflammatory response. The results of KEGG analysis indicated that the AGE-RAGE, NF-κB, HIF-1, IL-17, TNF, FoxO, and PPAR signalling pathways were enriched in the antidyslipidemic action of HLJDD. Conclusion. This study expounded the pharmacological actions and molecular mechanisms of HLJDD in treating dyslipidemia from a holistic perspective, which may provide a scientific basis for the clinical application of HLJDD.

Antrodia cinnamomea and its compound dehydroeburicoic acid attenuate nonalcoholic fatty liver disease by upregulating ALDH2 activity. JOURNAL OF ETHNOPHARMACOLOGY 2022; 292:115146. [PMID: 35304272 DOI: 10.1016/j.jep.2022.115146] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/15/2021] [Revised: 02/09/2022] [Accepted: 02/23/2022] [Indexed: 06/14/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Nonalcoholic fatty liver disease (NAFLD) is a prevalent liver disease, but currently has no specific medication in clinic. Antrodia cinnamomea (AC) is a medicinal fungus and it has been shown that AC can inhibit high fat diet (HFD)-induced lipid deposition in mouse livers, but the effective monomer in AC and mechanism against NAFLD remain unclear. It has been reported that aldehyde dehydrogenase 2 (ALDH2) activation shows protective effects on NAFLD. Our previous study demonstrates that AC and its monomer dehydroeburicoic acid (DEA) can upregulate the ALDH2 activity on alcoholic fatty liver disease mouse model, but it is not clear whether the anti-NAFLD effects of AC and DEA are mediated by ALDH2. AIM TO STUDY To elucidate the active compound in AC against NAFLD, study whether ALDH2 mediates the anti-NAFLD effects of AC and its effective monomer. MATERIALS AND METHODS WT mice, ALDH2-/- mice and ALDH2-/- mice re-expressed ALDH2 by lentivirus were fed with a methionine-choline deficient (MCD) diet or high fat diet (HFD) to induce NAFLD, and AC at the different doses (200 and/or 500 mg/kg body weight per day) was administrated by gavage at the same time. Primary hepatocytes derived from WT and ALDH2-/-mice were stimulated by oleic acid (OA) to induce lipid deposition, and the cells were treated with AC or DEA in the meantime. Lentivirus-mediated ALDH2-KD or ALDH2-OE were used to knock down or overexpress ALDH2 expression in HepG2 cells, respectively. Finally, the effects of DEA against NAFLD as well as its effects on upregulating liver ALDH2 and removing the harmful aldehyde 4-hydroxynonenal (4-HNE) were studied in the MCD diet-induced NAFLD mouse model. RESULTS In WT mice fed with a MCD diet or HFD, AC administration reduced hepatic lipid accumulation, upregulated ALDH2 activity in mouse livers, decreased 4-HNE contents both in mouse livers and serum, inhibited lipogenesis, inflammation and oxidative stress and promoted fatty acid β-oxidation. These effects were abolished in ALDH2 KO mice but could be restored by re-expression of ALDH2 by lentivirus. In primary hepatocytes of WT mice, AC and DEA inhibited OA-induced lipid accumulation and triglyceride (TG) synthesis, promoting the β-oxidation of fatty acid in the meantime. However, these effects were lost in primary hepatocytes of ALDH2 KO mice. Moreover, the expression level of ALDH2 significantly affected the inhibitory effects of AC and DEA on OA-induced lipid deposition in HepG2 cells. The effects of AC and DEA on suppressing lipid deposition, inhibiting mitochondrial ROS levels, reducing TG synthesis, and promoting β-oxidation of fatty acid were all enhanced with the overexpression of ALDH2 and reduced with the knockdown of ALDH2 expression. DEA showed dose-dependent effects on inhibiting liver lipid deposition, elevating ALDH2 activity and reducing 4-HNE levels in the livers of MCD diet-induced NAFLD mice. CONCLUSION DEA is the effective compound in AC against NAFLD. The related anti-NAFLD mechanisms of AC and DEA were through upregulating ALDH2 expression and activity, thus enhancing the elimination of 4-HNE in the livers, and sequentially alleviating oxidative stress and inflammation, promoting fatty acid β-oxidation and decreasing lipogenesis.

Abstract
The present study sought to elucidate the role of Polygonatum sibiricum F. Delaroche polysaccharide (PSP) in high‑fat diet (HFD)‑induced mouse obesity and investigated the primary molecular mechanism underlaying these effects. An obese mouse model was established by feeding HFD and three doses of PSP were administered intragastrically. Changes in body weight, serum lipids and parameters were recorded and the mechanism was explored by reverse transcription‑quantitative PCR and western blotting. Body weight, blood lipids, blood glucose, insulin, resistin, adiponectin, liver weight and abdominal fat pads weight were reduced by PSP and abnormal expression levels of inflammatory factors such as TNF‑α, IL‑6, IL‑1β and iNOS and lipid metabolism genes such as FAS, SREBP‑1, PPARα and CPT‑1were also reversed by PSP. The 5' adenosine monophosphate‑activated protein kinase (AMPK) signaling pathway was activated in PSP mouse liver, leading to lipid‑lowering and anti‑inflammatory effects. The results therefore suggested that PSP exhibited lipid‑lowering and anti‑inflammatory effects by activating the AMPK signaling pathway.

Abstract
Obesity is a major public health problem, and there is increasing scientific interest in its mechanisms, as well as a search for new compounds with antioxidant and anti-inflammatory properties that can minimize the metabolic complications associated with its pathology. One potential source of these compounds is natural products; Among these, flavonoids are a promising group of natural substances. Flavonoids are active constituents with diverse biological activities and are widely found in plants kingdom. Numerous studies have shown that flavonoids can effectively inhibit obesity and related metabolic disorders. The review synthesizes recent evidence in respect of progress in the understanding of the anti-obesity effects of flavonoids. Such effects which occurs through the modulation of proteins, genes and transcriptional factors involved in decreasing lipogenesis, increasing lipolysis, expenditure energy, stimulating fatty acids B-oxidation, digestion and metabolism of carbohydrates. In addition to mitigating inflammatory responses and suppress oxidative stress. A better understanding of the modulating effects and mechanisms of flavonoids in relation to obesity will allow us to better use these compounds to treat or even prevent obesity and its associated comorbidities.

Abstract
Diabetic retinopathy (DR) is a significant cause of vision loss and a research subject that is constantly being explored for new mechanisms of damage and potential therapeutic options. There are many mechanisms and pathways that provide numerous options for therapeutic interventions to halt disease progression. The purpose of the present literature review is to explore both basic science research and clinical research for proposed mechanisms of damage in diabetic retinopathy to understand the role of triglyceride and cholesterol dysmetabolism in DR progression. This review delineates mechanisms of damage secondary to triglyceride and cholesterol dysmetabolism vs. mechanisms secondary to diabetes to add clarity to the pathogenesis behind each proposed mechanism. We then analyze mechanisms utilized by both triglyceride and cholesterol dysmetabolism and diabetes to elucidate the synergistic, additive, and common mechanisms of damage in diabetic retinopathy. Gathering this research adds clarity to the role dyslipidemia has in DR and an evaluation of the current peer-reviewed basic science and clinical evidence provides a basis to discern new potential therapeutic targets.

Abstract
Poria cocos is the dried sclerotium of Wolfiporia cocos (F.A. Wolf) Ryvarden & Gilb., which was the current accepted name and was formerly known as Macrohyporia cocos (Schwein.) I. Johans. & Ryvarden, Pachyma cocos (Schwein.) Fr., Poria cocos F.A. Wolf and Sclerotium cocos Schwein. It is one of the most important crude drugs in traditional Chinese medicine, with a wide range of applications in ameliorating phlegm and edema, relieving nephrosis and chronic gastritis and improving uneasiness of minds. Its extensive pharmacological effects have attracted considerable attention in recent years. However, there is no systematic review focusing on the chemical compounds and pharmacological activities of Poria cocos. Therefore, this review aimed to provide the latest information on the chemical compounds and pharmacological effects of Poria cocos, exploring the therapeutic potential of these compounds. We obtained the information of Poria cocos from electronic databases such as SCI finder, PubMed, Web of Science, CNKI, WanFang DATA and Google Scholar. Up to now, two main active ingredients, triterpenes and polysaccharides of Poria cocos, have been identified from Poria cocos. It has been reported that they have pharmacological effects on anti-tumor, anti-bacterial, anti-oxidant, anti-inflammatory, immunomodulation, and liver and kidney protection. The review summarizes the phytochemistry and pharmacological properties of Poria cocos, which suggest that researchers should focus on the development of new drugs about Poria cocos to make them exert greater therapeutic potential.

Abstract
Antrodia cinnamomea is a Taiwanese medicinal mushroom with multiple pharmacological activities. Antrodia cinnamomea solid-state cultivated mycelium (LAC) exerts health-related effects in animal and cell models, but clinical data is limited. This study aimed to determine the safety and effects of LAC on human physiological functions. In an open-label, single-arm study, 32 healthy men and women ingested LAC capsules for three months. The subjects were monitored during the study and one month after the study end-point. LAC consumption did not significantly change fasting blood glucose, blood pressure, and triglyceride levels or liver and renal function indices. No adverse events occurred during the trial. Moreover, a significant change from baseline in total cholesterol levels was observed; men and women had decreases of 5.7% and 5.3%, respectively. Based on these, the ingestion of LAC-capsule has a considerable degree of safety and has the potential to reduce total cholesterol in healthy adults.

Antrodia cinnamomea Confers Obesity Resistance and Restores Intestinal Barrier Integrity in Leptin-deficient Obese Mice. Nutrients 2020; 12:nu12030726.

Abstract
Obesity is associated with metabolic disorders. Thus, obesity prevention and treatment are essential for health. Antrodia cinnamomea (AC) is a multifunctional medicinal fungus used for the treatment of various diseases and for preventing diet-induced obesity. Leptin deficiency causes over-eating and spontaneous obesity. The concomitant metabolic symptoms are more severe than diet-induced obesity. Here, we used leptin-deficient (ob/ob) mice as an animal model for over-feeding to study the effect of AC on obesity. We fed C57BL/6 mice (WT, ob+/+) and ob/ob mice with AC for four weeks before performing qRT-PCR and immunoblot analysis to elaborate AC-modulated mechanisms. Further, we used Caco-2 cells as a human intestinal epithelial barrier model to examine the effect of AC on intestinal permeability. Our results suggested that AC reduces lipid deposits of the liver and epididymal white adipose tissue (EWAT) by promoting lipid metabolism and inhibiting lipogenesis-associated genes and proteins in ob/ob mice. Moreover, AC effectively repaired intestinal-barrier injury caused by leptin deficiency and enhanced intestinal barrier integrity in Caco-2 cells. Interestingly, AC significantly reduced body weight and EWAT with no compromise on food intake in ob/ob mice. Thus, AC effectively reduced obesity caused by leptin-deficiency and can potentially be used as a nutraceutical for treating obesity.

Abstract
BACKGROUND AND OBJECTIVES The enteric nervous system (ENS) dominates the onset of obesity and has been shown to regulate nutrient absorption and energy metabolism. METHODS AND STUDY DESIGN This study was performed to investigate the role of electroacupuncture in regulating ENS function in obese mice. Obese mice were obtained by high-fat diet. 16S rRNA pyrosequencing, Western blotting, quantitative PCR, and neurotransmitter analysis were used for this purpose. RESULTS Body weight, Lee index, serum lipid, leptin, and adiponectin levels, and other basic indices were significantly ameliorated after electroacupuncture intervention. The pathological ENS scores, serum neurotransmitter levels, and intestinal transit rate were markedly changed in obese mice. Moreover, electroacupuncture promoted the diversity of gut microbiota. No significant differences were observed 21 and 28 days after electroacupuncture. CONCLUSIONS These results suggested ENS may be a new treatment approach to obesity.

Abstract
The occurrence of 3-methylglutaconic aciduria (3-MGA) is a well understood phenomenon in leucine oxidation and ketogenesis disorders (primary 3-MGAs). In contrast, its genesis in non-canonical (secondary) 3-MGAs, a growing-up group of disorders encompassing more than a dozen of inherited metabolic diseases, is a mystery still remaining unresolved for three decades. To puzzle out this anthologic problem of metabolism, three clues were considered: (i) the variety of disorders suggests a common cellular target at the cross-road of metabolic and signaling pathways, (ii) the response to leucine loading test only discriminative for primary but not secondary 3-MGAs suggests these latter are disorders of extramitochondrial HMG-CoA metabolism as also attested by their failure to increase 3-hydroxyisovalerate, a mitochondrial metabolite accumulating only in primary 3-MGAs, (iii) the peroxisome is an extramitochondrial site possessing its own pool and displaying metabolism of HMG-CoA, suggesting its possible involvement in producing extramitochondrial 3-methylglutaconate (3-MG). Following these clues provides a unifying common basis to non-canonical 3-MGAs: constitutive mitochondrial dysfunction induces AMPK activation which, by inhibiting early steps in cholesterol and fatty acid syntheses, pipelines cytoplasmic acetyl-CoA to peroxisomes where a rise in HMG-CoA followed by local dehydration and hydrolysis may lead to 3-MGA yield. Additional contributors are considered, notably for 3-MGAs associated with hyperammonemia, and to a lesser extent in CLPB deficiency. Metabolic and signaling itineraries followed by the proposed scenario are essentially sketched, being provided with compelling evidence from the literature coming in their support.

Abstract
We aimed to ascertain the mechanism underlying the effects of acteoside (ACT) from Ligustrum robustum (Roxb.) Blume (Oleaceae) on lipid metabolism and synthesis. ACT, a water-soluble phenylpropanoid glycoside, is the most abundant and major active component of L. robustum; the leaves of L. robustum, known as kudingcha (bitter tea), have long been used in China as an herbal tea for weight loss. Recently, based on previous studies, our team reached a preliminary conclusion that phenylpropanoid glycosides from L. robustum most likely contribute substantially to reducing lipid levels, but the mechanism remains unclear. Here, we conducted an in silico screen of currently known phenylethanoid glycosides from L. robustum and attempted to explore the hypolipidemic mechanism of ACT, the representative component of phenylethanoid glycosides in L. robustum, using RNA-seq technology, quantitative real-time PCR (qPCR) and Western blotting. First, the screening results for six compounds were docked with 15 human protein targets, and 3 of 15 protein targets were related to cardiovascular diseases. Based on previous experimental data and docking results, we selected ACT, which exerted positive effects, for further study. We generated a lipid accumulation model using HepG2 cells treated with a high concentration of oleic acid and then extracted RNA from cells treated for 24 h with 50 μmol/L ACT. Subsequently, we performed a transcriptomic analysis of the RNA-seq results, which revealed a large number of differentially expressed genes. Finally, we randomly selected some genes and proteins for further validation using qPCR and Western blotting; the results agreed with the RNA-seq data and confirmed their reliability. In conclusion, our experiments proved that ACT from L. robustum alters lipid metabolism and synthesis by regulating the expression of multiple genes, including Scarb1, Scarb2, Srebf1, Dhcr7, Acat2, Hmgcr, Fdft1, and Lss, which are involved several pathways, such as the glycolytic, AMPK, and fatty acid degradation pathways.

World J Gastroenterol 2019; 25:1492-1501. [PMID: 30948912 PMCID: PMC6441910 DOI: 10.3748/wjg.v25.i12.1492] [Citation(s) in RCA: 39] [Impact Index Per Article: 7.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/26/2018] [Revised: 01/29/2019] [Accepted: 01/30/2019] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Nonalcoholic fatty liver disease (NAFLD), the most common chronic liver disease, can progress into nonalcoholic steatohepatitis (NASH), cirrhosis, and even hepatocellular carcinoma. Bile acids such as ursodeoxycholic acid (UDCA) play an essential role in the pathogenesis of NAFLD by regulating the level of sterol regulatory element-binding protein (SREBP) 1c, but the underlying regulatory mechanism remains elusive. Increased evidence indicates that the AKT/mTOR/SREBP-1 signaling pathway is a key pathway to regulate hepatic cellular lipid metabolism. UDCA may regulate the AKT/mTOR/SREBP-1 signaling pathway to ameliorate hepatic lipid metabolism.
AIM To investigate the functional mechanism of UDCA in an oleic acid (OA)-induced cellular model of NAFLD.
METHODS The cellular model of NAFLD was established using OA and treated with UDCA. First, the best concentration of UDCA was selected. For the best time-dependent assay, cells were stimulated with OA only or co-treated with OA and 2 mmol/L UDCA for 24 h, 48 h, and 72 h. Oil red O staining was used to observe the accumulation of intracellular lipids, while the intracellular contents of triglyceride, alanine aminotransferase (ALT), gamma-glutamyl transpeptidase (GGT), and aspartate aminotransferase (AST) were detected by enzymatic methods. Meanwhile, the expression levels of AKT/mTOR/SREBP-1 signaling pathway-related proteins were detected by real-time PCR and Western blot.
RESULTS In the NAFLD cell model established with LO2 cells induced using OA, lipid accumulation was obvious. UDCA significantly inhibited lipid accumulation at different concentrations (especially 2 mmol/L) and decreased cell growth ability at different time points. The biochemical parameters like ALT, AST, and GGT were significant improved by UDCA. UDCA treatment vividly repressed the activation of AKT, mTOR, and CRTC2 and the expression of nSREBP-1 in LO2 cells induced with OA.
CONCLUSION Our findings demonstrate the effect of UDCA in improving NAFLD. UDCA attenuates OA-induced hepatic steatosis mainly by regulation of AKT/mTOR/SREBP-1 signal transduction.

Abstract
Peroxisome proliferator-activated receptor α (PPARα) is a nuclear hormone receptor that transcriptionally regulates lipid metabolism and inflammation; therefore, PPARα agonists are promising agents to treat dyslipidemia and metabolic disorders. PPARα full agonists, such as fibrates, are effective anti-hypertriglyceride agents, but their use is limited by adverse side effects. Hence, the aim of this study was to identify small molecules that can activate PPARα while minimizing the adverse effects. Antrodia cinnamomea, a rare medical mushroom, has been used widely in Asian countries for the treatment of various diseases, including liver diseases. Antcin B, H and K (antcins) and ergostatrien-3β-ol (EK100) are bioactive compounds isolated from A. cinnamomea with anti-inflammatory actions. Antcins, ergostane-type triterpenoids, contain the polar head with carboxylate group and the sterol-based body. Here, we showed at the first time that sterol-based compounds, antcins, but not EK100, activate PPARα in a cell-based transactivation study. The in silico docking studies presented several significant molecular interactions of antcins, including Tyr314, and His440 in the ligand-binding domain of PPARα, and these interactions are required for helix 12 (H12) stabilization. We propose that PPARα activation activity of antcins is related to their binding mode which requires conventional H12 stabilization, and that antcins can be developed as safe selective PPARα modulators.

Abstract
Recently, gut flora has been linked to the onset of obesity and has been shown to influence the host's metabolism. Acupuncture is a well-known agent used for the treatment of numerous diseases such as obesity. This study aimed to explore the impacts of electroacupuncture treatment on gut microbiota composition and function in obese mice. Pyrosequencing of 16S rRNA genes and Metagenomic analysis of the fecal microbiota were used for this purpose. The basic parameters of body weight, Lee's index, serum lipid and epididymal adipose weight were ameliorated significantly after introducing an electroacupuncture intervention. Acidobacteria, Cyanobacteria and Basidiomycota (Normal group) and Fusobacteria, Firmicutes and Spirochmycetes (Model group) were remarkably affluent at the phylum level. Bacteroides sp. CAG: 927 and Prevotella sp. CAG: 1031 (Normal group), Lachnospiraceae bacterium and Helicobacter rodentium (Model group) at the species level were distinctly enriched. The structures and functions of the intestinal flora were significantly different between healthy and obese mice, and animals in the acupuncture group gradually tended towards healthy controls. Moreover, electroacupuncture altered the bacterial diversity and metabolic genes to establish new balance, observed the obvious change from 7[Formula: see text]d and stabilized gradually through 21[Formula: see text]d. These findings suggested gut flora could be a novel target of electroacupuncture treatment against obesity.

Abstract
Danggui-Baizhu-Tang (DBT), a traditional Chinese medicine decoction, was used for decreasing serum TG and TC remarkably. However, effect of weight control and action mechanism remains confused. In this study, to evaluate the anti-obesity effects, different gradient concentration of DBT (0.59, 1.17 g/kg) or Orlistat (Orl, 15.6 mg/kg; positive control) were administrated by gavage for 8 weeks in C57BL/6J mice which were pretreated with chow or high fat diet (HFD) for 3 months. After administration, significant decrease of body weight and food utilization was observed. It was indicated that concentration of triacylglycerol (TG), total cholesterol (TC), alanine aminotransferase (ALT), aspartate aminotransferase (AST) in serum were reduced strikingly, as well as accumulation of lipid droplets in liver. Meanwhile, DBT treatment could also decrease weight of white adipose tissue (WAT) and size of adipocytes, whereas increase weight of brown adipose tissue (BAT) in mice. Moreover, it was revealed that DBT could elevate rectal temperature by raising expression of uncoupling protein-1 (UCP1) and peroxisome proliferator-activated receptor-gamma coactivator-1alpha (PGC-1α), which were attributed to phosphorylation of AMP-activated protein kinase (AMPK). Furthermore, TNF-α and IL-6, obesity-related inflammatory cytokines, were decreased. In conclusion, DBT could stimulate phosphorylation of AMPK to raise expression of UCP1 and PGC-1α, and activate thermogenesis to prevent obesity.

Abstract
Background This study aimed to analyze the effect of exercise and/or dietary change on improvement of non-alcoholic fatty liver disease (NAFLD) in chronic high-fat diet (HFD)-induced obese mice. Methods Forty male C57BL/6 (8 weeks old) mice were divided into normal diet (CO, n = 8) and high-fat diet (HF, n = 32) groups. The HF group was fed with 60% fat chow for 16 weeks to induce obesity. After the obesity induction period, the HF group was subdivided into HFD + sedentary (n = 8), HFD + training (HFT, n = 8), dietary change to normal-diet + sedentary (HFND, n = 8), and dietary change to normal-diet + training (HFNDT, n = 8) groups, and the mice in the training groups underwent treadmill training for 8 weeks, 5 times per week, 40 min per day. Results A 24-week HFD induced increase of cannabinoid-1 receptor (CB1), fatty acid synthase (FAS), and AMP-activated protein kinase (AMPK) protein expressions (p < 0.05) and decrease of p-AMPK and carnitine palmitoyltransferase1 (CPT1) protein expressions (P < 0.05), resulting in increased liver fat accumulation. Treatment of exercise with dietary change and dietary change alone decreased CB1 and AMPK protein expressions with increased p-AMPK and CPT1 protein expressions (P < 0.05), leading to decreased body weight and liver fat (P < 0.05). The CB1 and FAS protein expressions in the HFT group were still higher than those in the CO group (P < 0.05), but the p-AMPK and CPT1 protein expressions were higher than those in the HF group (P < 0.05). Moreover, improved glucose tolerance and decreased liver fat were confirmed, although treatment of exercise alone had no effect on weight loss compared to pre-exercise. Conclusions Even in the case of obesity induced by chronic HFD, exercise and/or dietary interventions have preventive and therapeutic effects on fat accumulation in the liver, resulting from upregulations of lipolytic factors. Therefore, the results of this study suggested that treatment of exercise alone without dietary change also leads to improvement of NAFLD and glucose tolerance without weight loss benefits.

Abstract
Previous investigations have shown molecular cross-talk among activated adenosine monophosphate-activated protein kinase (AMPK), proprotein convertase subtilisin/kexin type 9 (PCSK9), sterol regulatory element-binding proteins (SREBPs), and low-density lipoprotein receptor (LDLR) and that it may be an innovative pharmacologic objective for treating obesity. We scrutinized the beneficial effect of naringin, a flavanone-7- O-glycoside, on obesity and the mechanisms in the present study. We arbitrarily divided 50 mice into five groups ( n = 10): 25 or 50 or 100 mg/kg/day naringin-treated obese mice (gavage for 8 weeks), untreated obese mice, and C57BL/6J control. After 8 weeks, body weight was 51.8 ± 4.4 in the untreated obese mice group, while the weights were 41.4 ± 4.1, 34.6 ± 2.2, and 28.0 ± 2.3 in 25, 50,100 mg/kg naringin groups, respectively. Moreover, naringin treatment significantly decreased plasma 8-isoprostane (an indicator of the oxidative stress) level, fat weight, liver weight, hepatic total cholesterol concentration, hepatic triglyceride concentration, plasma leptin level, plasma insulin content, plasma low-density lipoprotein cholesterol level, and plasma PCSK9 production concomitantly with down-regulated expression of SREBP-2, PCSK9, and SREBP-1, and up-regulated expression of p-AMPKα and LDLR. The present results suggest that naringin activates AMPK resulting in altered expression of SREBPs, PCSK9, and LDLR to reduce the body weight of obese C57BL/6J mice.

Abstract
Antrodia cinnamomea (AC) is a medicinal fungal species that has been widely used traditionally in Taiwan for the treatment of diverse health-related conditions including cancer. It possesses potent anti-inflammatory and antioxidant properties in addition to its ability to promote cancer cell death in several human tumors. Our aim was to improve the anticancer activity of AC in hepatocellular carcinoma (HCC) through its cocultivation with ginger aiming at tuning the active ingredients. HCC cell lines, Huh-7 and HepG2 were used to study the in vitro anticancer activity of the ethanolic extracts of AC (EAC) alone or after the cocultivation in presence of ginger (EACG). The results indicated that the cocultivation of AC with ginger significantly induced the production of important triterpenoids and EACG was significantly more potent than EAC in targeting HCC cell lines. EACG effectively inhibited cancer cells growth via the induction of cell cycle arrest at G2/M phase and induction of apoptosis in Huh-7 and HepG2 cells as indicated by MTT assay, cell cycle analysis, Annexin V assay, and the activation of caspase-3. In addition, EACG modulated cyclin proteins expression and mitogen-activated protein kinase (MAPK) signaling pathways in favor of the inhibition of cancer cell survival. Taken together, the current study highlights an evidence that EACG is superior to EAC in targeting cancer cell survival and inducing apoptotic cell death in HCC. These findings support that EACG formula can serve as a potential candidate for HCC adjuvant therapy.

Abstract
Genstein is the most abundant phytoestrogen in soybean that was reported to play positive roles in menopausal syndrome and metabolic syndrome. In the present study, we investigated the effects and potential mechanisms of genistein against progression of nonalcoholic fatty liver disease (NAFLD) in BRL cells treated with fatty acid mixture (oleate/palmitate, 2:1 ratio). Our data demonstrated that genistein remarkably improved fatty acid mixture-induced hepatocelluler fat accumulation, inhibited upregulation of genes expression related to fatty acid synthesis, and derepressed those associated with fatty acid oxidation. In addition, the results displayed that genistein promoted the phosphorylation of adenosine monophosphate-activated protein kinase (AMPK) suppressed by fatty acid, which were significantly weakened by compound C, an AMPK inhibitor. Taken all together, genistein is capable to ameliorate fat accumulation through regulation of fatty acid metabolism mediated by AMPK activation in BRL cells. Further investigations are needed to verify the protective effects of genistein on NAFLD model in in vivo animal study or in vitro human cell lines along with absorption, distribution, metabolism, and excretion studies of genistein. PRACTICAL APPLICATION Genistein is able to ameliorate fat accumulation through regulation of fatty acid metabolism mediated by AMPK activation in vitro.

Abstract
Yak is a wild bovine species living on the Qinghai Tibet Plateau that demonstrates good adaptability to the hypoxic environment. Chicoric acid, a natural phenolic compound, is known as having anti-oxidant, antiviral, anti-inflammatory and analgesic properties. However, its effect on hypoxia adaptability of yak is still unclear. In this study 40 yaks were selected that were of similar age, parity and weight, and divided into the control group and experimental groups 1, 2, 3, randomly. Results showed that chicoric acid significantly improved RBC, HGB, and WBC. There are significantly beneficial effects to increasing total protein contents ([Formula: see text]): all treatments increased HDL-C contents, and supplementations 100[Formula: see text]mg/h significantly decreased the content of TG on the 60th day ([Formula: see text]). Contents of the serum related enzymes like ALP, GOP and GPT showed varying degrees of change, but no significant differences and the indexes of anti-oxidant capacity (T-AOC and GSH-Px) were significantly improved ([Formula: see text]), but MDA was decreased ([Formula: see text]) under the action of the chicoric acid. Hypoxia-inducible factor in serum such as HIF-2[Formula: see text], EPO, ROS, Fe[Formula: see text] and Tf are all significantly decreased ([Formula: see text]). The myocardial mitochondrial parameters mtDNA, UCP2, PGC1-[Formula: see text], NRF1 and mitochondrial complexes were altered remarkably. Some indicators of glucose metabolism presented variation trends. Taken together, chicoric acid has shown a positive effect on the adaptive ability of yak in high altitude, hypoxic environment in plateau areas. Our findings reported a new potential means to enhance immunity and inflammatory response and improve the anti-oxidant capacity.

Abstract
Insulin resistance is a major factor in type II diabetes development, occurring when insulin levels are normal, but do not have normal interactions with adipose, muscle or liver tissue. The present study aimed to explore the hypoglycemic effect of Antrodia cinnamomea (AC) mycelium powder by evaluating its impact on insulin resistance and plasma free fatty acid (FFA) levels in steroid‑induced insulin‑resistant (SIIR) rats. Male Wistar rats were administered dexamethasone for 5 days to induce insulin resistance. The SIIR rats were subsequently randomly assigned into three experimental groups (EGs) and a control group (CG), where saline was orally administered. The EGs were orally administered different doses of AC (100, 200 or 500 mg/kg) and an optimal dose for further study was determined. Changes in plasma insulin and glucose levels were calculated to investigate the hypoglycemic effect of AC. To evaluate insulin resistance, the homeostasis model assessment‑estimated insulin resistance of the SIIR rats was determined. Changes in plasma FFA levels were detected and levels of insulin signal proteins (IRS‑1, GLUT‑4 and PI3K) were analyzed by western blot to elucidate AC's mechanism of action. The SIIR rats exhibited significantly decreased plasma glucose levels in the first 30 min, with plasma FFA levels displaying a marked downward trend (P<0.05) when they were administered the optimal dose of AC (200 mg/kg). The decrease in plasma glucose and FFA levels was significantly larger in the EG compared to the CG, and insulin signal protein levels were also significantly increased (P<0.05). The hypoglycemic effect observed may be due to decreased plasma FFA levels and increased expression of intracellular insulin signal proteins. Furthermore, insulin sensitivity was enhanced, indicating that AC acts as an insulin sensitizer in insulin resistant animal models.

Abstract
Alcohol exposure is a major reason of morbidity and mortality all over the world, with much of detrimental consequences attributing to alcoholic liver disease (ALD). With the continued ethanol consumption, alcoholic fatty liver disease (AFLD, the earliest and reversible form of ALD) can further develop to more serious forms of alcoholic liver damage, including alcoholic steatohepatitis, fibrosis/cirrhosis, and even eventually progress to hepatocellular carcinoma and liver failure. Furthermore, cell trauma, inflammation, oxidative stress, regeneration, and bacterial translocation are crucial promoters of ethanol-mediated liver lesions. AFLD is characterized by excessive fat deposition in liver induced by excessive drinking, which is related closely to the raised synthesis of fatty acids and triglyceride, reduction of mitochondrial fatty acid β-oxidation, and the aggregation of very-low-density lipoprotein (VLDL). Although little is known about the cellular and molecular mechanisms of AFLD, it seems to be correlated to diverse signal channels. Massive studies have suggested that liver steatosis is closely associated with the inhibition of silent information regulator 1 (SIRT1) and the augment of lipin1 β/α ratio mediated by ethanol. Recently, serine/arginine-rich splicing factor 10 (SFRS10), a specific molecule functioning in alternative splicing of lipin 1 (LPIN1) pre-mRNAs, has emerged as the central connection between SIRT1 and lipin1 signaling. It seems a new signaling axis, SIRT1-SFRS10-LPIN1 axis, acting in the pathogenesis of AFLD exists. This article aims to further explore the interactions among the above three molecules and their influences on the development of AFLD. Impact statement ALD is a major health burden in industrialized countries as well as China. AFLD, the earliest and reversible form of ALD, can progress to hepatitis, fibrosis/cirrhosis, even hepatoma. While the mechanisms, by which ethanol consumption leads to AFLD, are complicated and multiple, and remain incompletely understood. SIRT1, SFRS10, and LIPIN1 had been separately reported to participate in lipid metabolism and the pathogenesis of AFLD.
