We evaluated the effects of cinnamon polyphenol extract on hepatic transcription factors expressions including SREBP-1c and LXR-α in rats fed high fat diet (HFD). Twenty-eight Wistar rats were allocated into four groups: (i) normal control: animals fed with normal chow; (ii) cinnamon: animals supplemented with cinnamon polyphenol; (iii) HFD: animals fed a high-fat diet; and (iv) HFD + cinnamon: animals fed a high-fat diet and treated with cinnamon polyphenol. Obesity was linked to hyperglycemia, hyperlipidemia, and oxidative stress as imitated by elevated serum glucose, lipid profile, and serum and liver malondialdehyde (MDA) concentrations. Cinnamon polyphenol decreased body weight, visceral fat, liver weight and serum glucose and insulin concentrations, liver antioxidant enzymes, and lipid profile (P<0.05) and reduced serum and liver MDA concentration compared to HFD rats (P<0.05). Cinnamon polyphenol also suppressed the hepatic SREBP-1c, LXR-α, ACLY, FAS, and NF-κB p65 expressions and enhanced the PPAR-α, IRS-1, Nrf2, and HO-1 expressions in the HFD rat livers (P<0.05). In conclusion, cinnamon polyphenol reduces the hyperlipidemia, inflammation, and oxidative stress through activating transcription factors and antioxidative defense signaling pathway in HFD rat liver.

Nonalcoholic fatty liver disease (NAFLD) is caused by fat accumulation and is related with obesity and oxidative stress. In this study, we investigated the effect of cuminaldehyde on NAFLD in rats fed a high fat diet (HFD). Male Wistar rats were fed a HFD for 42 days to induce NAFLD. The progression of NAFLD was evaluated by histology and measuring liver enzymes (alanine transaminase and aspartate transaminase), serum and hepatic lipids (total triglycerides and total cholesterol), and oxidative stress markers (thiobarbituric acid reactive substances, glutathione, superoxide dismutase, and catalase). The HFD feeding increased the liver weight and caused NAFLD, liver steatosis, hyperlipidemia, oxidative stress, and elevated liver enzymes. Administration of cuminaldehyde ameliorated the changes in hepatic morphology and liver weight, decreased levels of liver enzymes, and inhibited lipogenesis. Our findings suggest that cuminaldehyde could improve HFD-induced NAFLD via abolishment of hepatic oxidative damage and hyperlipidemia. Cuminaldehyde might be considered as a potential aromatic compound in the treatment of NAFLD and obesity through the modulation of lipid metabolism.

The present study was to investigate whether amagnoliaextract, named BL153, can prevent obesity-induced liver damage and identify the possible protective mechanism. To this end, obese mice were induced by feeding with high fat diet (HFD, 60% kcal as fat) and the age-matched control mice were fed with control diet (10% kcal as fat) for 6 months. Simultaneously these mice were treated with or without BL153 daily at 3 dose levels (2.5, 5, and 10 mg/kg) by gavage. HFD feeding significantly increased the body weight and the liver weight. Administration of BL153 significantly reduced the liver weight but without effects on body weight. As a critical step of the development of NAFLD, hepatic fibrosis was induced in the mice fed with HFD, shown by upregulating the expression of connective tissue growth factor and transforming growth factor beta 1, which were significantly attenuated by BL153 in a dose-dependent manner. Mechanism study revealed that BL153 significantly suppressed HFD induced hepatic lipid accumulation and oxidative stress and slightly prevented liver inflammation. These results suggest that HFD induced fibrosis in the liver can be prevented partially by BL153, probably due to reduction of hepatic lipid accumulation, inflammation and oxidative stress.

Background: Dillenia indica (Family: Dilleniaceae) is an antioxidant-rich edible fruit-bearing medicinal plant. The fruit of this plant (known as elephant apple) has many uses in traditional medicine. Objective: By considering its antioxidant content and ameliorating effects this study was aimed to evaluate the antiadipogenic effects of D. indica fruit extract (DIFE) in high-fat diet (HFD) fed obese rats. Methods: Male Wistar rats were fed with a standard diet (SD), or high-fat diet (HFD), or HFD with 100 mg/kg or 200 mg/kg or 400 mg/kg DIFE for 8 weeks. The fruit extract was given orally by feeding gavage. The body weight, liver weight, visceral fat weight, plasma lipids, and oxidative stress-related parameters were measured. The mRNA level of different adipogenesis related transcription factors, lipogenic and lipolytic enzymes was also evaluated. Results: Consumption of DIFE daily (400 mg/kg) for 8 weeks resulted in a significant reduction of high-fat diet-induced body weight, liver weight, visceral fat weight, total cholesterol, and LDL-cholesterol level. High-fat diet-mediated elevation of oxidative stress markers was also lowered, with a parallel augmentation of the activities of antioxidant enzymes, due to 400 mg/kg DIFE feeding. DIFE also down-regulated the mRNA level of important pro-adipogenic factors like PPARγ, LXRα, and SREBP1c which consequently down-regulated the transcript levels of lipogenic enzymes: ACC, FAS, HMHCR, and DGAT. The transcript level of lipolytic enzyme, HSL was also down-regulated in 400 mg/kg DIFE-fed rats. Conclusion: These findings indicate that the antioxidant-rich ethanolic extract of D. indica fruit can down-regulate the gene expression of pro-adipogenic transcription factors and lipid metabolizing enzymes and thus can suppress dietinduced obesity in Wistar rat.

Objectives: CNM (CNM) polyphenol has antioxidant and anti-inflammatory properties. Therefore, we hypothesized CNM decrease heart disease risk factors and may enhance anti- inflammatory properties in rats fed a diet containing CNM. In this study, we evaluated the effects of CNM polyphenol on insulin resistance (IR), hyperlipidemia, hepatic transcription factors expressions [sterol regulatory element-binding protein1c (SREBP-1c), liver X receptor-α (LXR-α), nuclear factor kappa B p65 (NF-κB p65), nuclear factor-E2-related factor-2 (Nrf2)] in rats fed high fat diet (HFD). Method: Twenty-eight Wistar rats were allocated into four groups; (i) normal control; animals fed with normal chow (C ) (ii) CNM (C+CNM 100 mg/kg b.wt.), (iii) HFD (42% of calories as fat, high fat diet [HFD]), and (iv) HFD + CNM for 12 weeks. Blood analysis for triglycerides (TG) and cholesterol (CHOL), glucose, insulin, malonaldehyde (MDA a marker of oxidative stress [OS]) were estimated. Body weight, visceral fat and liver weight recorded and liver MDA assessed. SREBP-1c, LXR-α, ATP-citrate lyase (ACLY), fatty acid synthase (FAS), NF-κB p65 expressions and decreased the PPAR-α, p-IRS-1, Nrf2, HO-1 proteins were evaluated by Western blotting. Results: HFD rats of the liver had increased SREBP-1c, LXR-α, ATP-citrate lyase (ACLY), fatty acid synthase (FAS), NF-κB p65 expressions and decreased the PPAR-α, p-IRS-1, Nrf2, HO-1 expressions compared to control group. CNM supplementation decreased body weight (8.4%), visceral fat (36.6%), liver weight (17.7%), serum glucose and insulin concentrations, lipid profile ( P < 0.05), and serum and liver MDA (23.3% and 25.4 %) concentration compared to HFD rats ( P < 0.05). CNM decreased hepatic SREBP-1c (18.1 %), LXRα (27.9%), ATP-citrate lyase (ACLY, 22.7 %), fatty acid synthase (FAS, 15.8 %), NF-κB p65 (23.3%) and enhanced the PPAR-α, IRS-1 (72.7 %), Nrf2 (111.7 %) and HO-1 (72.1 %) proteins in HFD rat livers ( P < 0.05). Discussion: These results suggest CNM supplementation reduces hyperlipidemia, inflammation, and oxidative stress through activating transcription factors (SREBP-1c, LXR-α, NF-κB, and Nrf2) and anti-oxidative defense signaling pathway.

Abstract Background Different parts of the medicinal plant Tamarindus indica L. are full of phytochemicals that are able to reduce elevated blood pressure, blood sugar and lipids. These pharmacological effects are due to the presence of antioxidant type compounds in those parts of the plant. This study was aimed to explore the molecular mechanism of anti-obesity effects of ethanolic extract of T. indica L. leaves (TILE) through the evaluation of biochemical parameters and gene expression analysis in high-fat diet (HFD) consuming Wistar rats. Methods Male Wistar rats were supplied with a standard diet (SD), or HFD, or HFD with 100 mg/kg or 200 mg/kg or 400 mg/kg TILE for 8 weeks. The body weight, liver weight, fat weight, plasma lipids, and oxidative stress-related parameters were measured. The transcript levels of different adipogenesis related transcription factors, lipogenic enzymes, and lipolytic enzymes were also evaluated by quantitative real-time PCR. Result Phytochemical analysis demonstrated that TILE is enriched with a substantial level of polyphenols (287.20 ± 9.21 mg GAE/g extract) and flavonoids (107.52 ± 11.12 mg QE/g extract) which might be the reason of significant antioxidant and radical scavenging activities. Feeding of TILE (400 mg/kg/day) to HFD-fed rats increased activity of superoxide dismutase and catalase which is reflected as a significant reduction of oxidative stress markers like nitric oxide and malondialdehyde. TILE (400 mg/kg/day) feeding also down-regulated the mRNA levels of proadipogenic transcription factors including liver X receptor alpha (LXRα), peroxisome proliferator-activated receptor gamma (PPARγ), and sterol regulatory element-binding protein 1c (SREBP1c) in diet-induced obese rats. As a consequence of this, the mRNA level of lipogenic enzymes like acetyl-CoA carboxylase (ACC), fatty acid synthase (FAS), diacylglycerol acyltransferase (DGAT), and HMG-CoA reductase was down-regulated with a parallel up-regulation of the transcript level of lipolytic enzyme, hormone-sensitive lipase (HSL). Conclusion Observations from this study indicate that antioxidant-rich TILE can reduce HFD-induced body weight, fat weight and liver weight as well as blood lipids through down-regulating the gene expression of proadipogenic transcription factors and lipogenic enzymes with a concerted diminution of the gene expression of lipolytic enzyme, HSL.
