High fat diet (HFD) is associated with oxidative stress induced fatty liver. Curcumin, an extract of Curcuma longa, has been shown to possess potent antioxidant and hypolipidemic properties. In this study, we investigated the effect of curcumin treatment on hepatic heme oxygenase-1 (HO-1) expression along with pro-oxidant–antioxidant status and lipid accumulation in rats fed an HFD. Male Sprague–Dawley rats were distributed among 4 groups: Group 1, which was fed the control diet (10% of total calories from fat); Group 2, which was fed the HFD (60% of total calories from fat); and groups 3 and 4, which received the HFD supplemented with curcumin and the control diet supplemented with curcumin (1 g/kg diet; w/w), respectively, for 16 weeks. HFD caused increases in hepatic lipid levels, production of reactive oxygen species, and lipid peroxidation. Further, HO-1 expression was significantly decreased. Histopathological examination showed hepatic fat accumulation and slight fibrotic changes. Curcumin treatment reduced hepatic lipids and oxidative stress parameters, and HO-1 expression was significantly increased. These findings suggest that increased HO-1 expression, along with suppressed oxidative stress as well as reduced hepatic fat accumulation and fibrotic changes, contribute to the beneficial effects of curcumin in attenuating the pathogenesis of fatty liver induced metabolic diseases.

The objective of this study was to evaluate the effects of the hot-water extract of defatted Camellia oleifera seeds (CSE) on body and liver fat accumulation in rats. Forty rats were divided into 5 groups and each group was fed either an isocaloric control diet or a high-fat liquid diet with 0% (H), 0.12% (H1), 0.24% (H2), or 0.48% CSE (H3) for 8 weeks. Ingestion of the high-fat liquid diet increased abdominal and liver fat accumulation, although no difference was found in body weights compared with rats fed the control diet. We found that rats fed the H2 and H3 diets had lower plasma alanine aminotransferase activities than the H group in the fourth and eighth weeks. At the end of the study, the H2 and H3 groups also had lower epididymal and retroperitoneal fat masses, and all CSE groups had lower circulatory leptin levels than the H group. CSE consumption decreased hepatic fat accumulation in terms of liver triglycerides and a histopathology analysis, and ameliorated high-fat diet-induced elevation of hepatic tumor necrosis factor-α levels. We also found that CSE groups had lower malondialdehyde and hydroxyproline levels in the liver. Our results suggested that CSE may exert beneficial effects through decreasing body fat accumulation and hepatic steatosis and regulating adipokine levels in diet-induced nonalcoholic fatty liver disease.

Oxidative stress from fat accumulation in the liver has many deleterious effects. Many believe that there is a second hit that causes relatively benign fat accumulation to transform into liver failure. Therefore, we evaluated the effects of ethanol on ex vivo precision-cut liver slice cultures (PCLS) from rats fed a high-fat diet resulting in fatty liver. Age-matched male Sprague-Dawley rats were fed either high-fat (obese) (45% calories from fat, 4.73 kcal/g) or control diet for 13 mo. PCLS were prepared, incubated with 25 mM ethanol for 24, 48, and 72 h, harvested, and evaluated for ethanol metabolism, triglyceride production, oxidative stress, and cytokine expression. Ethanol metabolism and acetaldehyde production decreased in PCLS from obese rats compared with age-matched controls (AMC). Increased triglyceride and smooth muscle actin production was observed in PCLS from obese rats compared with AMC, which further increased following ethanol incubation. Lipid peroxidation, measured by thiobarbituric acid reactive substances assay, increased in response to ethanol, whereas GSH and heme oxygenase I levels were decreased. TNF-α and IL-6 levels were increased in the PCLS from obese rats and increased further with ethanol incubation. Diet-induced fatty liver increases the susceptibility of the liver to toxins such as ethanol, possibly by the increased oxidative stress and cytokine production. These findings support the concept that the development of fatty liver sensitizes the liver to the effects of ethanol and leads to the start of liver failure, necrosis, and eventually cirrhosis.

Oxidative Effects

Inhibiting the onset of arteriosclerotic disease, which has been increasing due to the westernized diet and aging, is a significant social challenge. Curcumin, a type of polyphenol, has anti-oxidative effects and anti-inflammatory action and is expected to treat and to have prophylactic effects on different diseases. In this study, we examined the effects of long-term administration of curcumin on vascular aging and chronic inflammation—the causes of arteriosclerotic disease. Eight-week-old C57BL/6J mice were fed with high fat diet (HFD) or 0.1% curcumin-mixed HFD (HFD + Cu) until 80 weeks old (n = 20 for each group). After the breeding, we examined the expression of antioxidant enzymes, heme oxygenase-1 (HO-1), oxidative stress, vascular aging, and inflammatory changes in the aorta. In the HFD group, oxidative stress increased with decreased sirt1 expression in the aorta followed by increased senescent cells and enhanced inflammation. Whereas in the HFD + Cu group, HO-1 was induced in the aorta with the suppression of oxidative stress. Additionally, it was shown that sirt1 expression in the aorta in the HFD + Cu group remained at a level comparable to that of the 8-week-old mice with suppression of increased senescent cells and enhanced inflammation. Consequently, disorders associated with HFD were resolved. These results suggest that curcumin might be a food with a prophylactic function against arteriosclerotic disease.

High-fat diet (HFD) consumption has been linked to dyslipidemia, low-grade inflammation and oxidative stress. This study investigated the effects of a mixed formulation with Limosilactobacillusfermentum 139, L. fermentum 263 and L. fermentum 296 on cardiometabolic parameters, fecal short-chain fatty acid (SCFA) contents and biomarkers of inflammation and oxidative stress in colon and heart tissues of male rats fed an HFD. Male Wistar rats were grouped into control diet (CTL, n = 6), HFD (n = 6) and HFD with L. fermentum formulation (HFD-Lf, n = 6) groups. The L.fermentum formulation (1 × 109 CFU/mL of each strain) was administered twice a day for 4 weeks. After a 4-week follow-up, biochemical parameters, fecal SCFA, cytokines and oxidative stress variables were evaluated. HFD consumption caused hyperlipidemia, hyperglycemia, low-grade inflammation, reduced fecal acetate and propionate contents and increased biomarkers of oxidative stress in colon and heart tissues when compared to the CTL group. Rats receiving the L. fermentum formulation had reduced hyperlipidemia and hyperglycemia, but similar SCFA contents in comparison with the HFD group (p < 0.05). Rats receiving the L. fermentum formulation had increased antioxidant capacity throughout the colon and heart tissues when compared with the control group. Administration of a mixed L. fermentum formulation prevented hyperlipidemia, inflammation and oxidative stress in colon and heart tissues induced by HFD consumption.

Abstract Objectives High fat diet (HFD)-induced obesity links with prevalence of metabolic dysfunction, including low-grade chronic inflammation, insulin resistance, and hepatic steatosis. Dry edible beans (DEBs) play a significant role in human nutrition as a rich source of proteins, carbohydrates, fibers, and various micronutrients. The aim of this study is to evaluate the ability of red kidney beans (RKBs) to attenuate the deleterious effects of HFD in the liver. Methods Syrian hamsters were randomly assigned with one of five experimental diet groups; low fat diet (control), high fat diet, high fat diet with 5% whole beans (HFD + B), high fat diet with 4.5% dehulled beans (HFD + DHB) and high fat diet with 0.5% hull of beans (HFD + HB) and fed for 4 weeks. Results Supplementation of RKB resulted in lower body weight, liver weight, and glucose levels (P &lt; 0.001) in HFD + B and HFD + DHB group compared to HFD group. Adding RKBs downregulated gene expressions related to inflammation (e.g., interleukin 6 (IL-6)) and lipogenesis (e.g., hepatic fatty acid synthase (FASN)) in the liver. Furthermore, RKBs supplemented groups showed reduced hepatic fat accumulation in comparison with the HFD group. Conclusions Supplementation of RKBs and their hulls attenuates hepatic stresses by decreasing the lipogenesis and inflammation, which contribute to enhancing insulin sensitivity.

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.

Selenoprotein W (SelW) is a selenium-containing protein with a redox motif found abundantly in the skeletal muscle of rodents. Previous in vitro studies suggest that SelW plays an antioxidant role; however, relatively few in vivo studies have addressed the antioxidant role of SelW. Since oxidative stress is a causative factor for the development of insulin resistance in obese subjects, we hypothesized that if SelW plays a role as an antioxidant, SelW deficiency could aggravate the oxidative stress and insulin resistance caused by a high-fat diet. SelW deficiency did not affect insulin sensitivity and H2O2 levels in the skeletal muscle of control diet-fed mice. SelW levels in the skeletal muscle were decreased by high-fat diet feeding for 12 wk. High-fat diet induced obesity and insulin resistance and increased the levels of H2O2 and oxidative stress makers, which were not affected by SelW deficiency. High-fat diet feeding increased the expression of antioxidant enzymes; however, SelW deficiency did not affect the expression levels of antioxidants. These results suggest that SelW does not play a protective role against oxidative stress and insulin resistance in the skeletal muscle of high-fat diet-fed obese mice.
