Alcohol, White Adipose Tissue, and Brown Adipose Tissue: Mechanistic Links to Lipogenesis and Lipolysis.

According to data from the World Health Organization, there were about 3 million deaths caused by alcohol consumption worldwide in 2016, of which about 50% were related to liver disease. Alcohol consumption interfering with the normal function of adipocytes has an important impact on the pathogenesis of alcoholic liver disease. There has been increasing recognition of the crucial role of adipose tissue in regulating systemic metabolism, far beyond that of an inert energy storage organ in recent years. The endocrine function of adipose tissue is widely recognized, and the significance of the proteins it produces and releases is still being investigated. Alcohol consumption may affect white adipose tissue (WAT) and brown adipose tissue (BAT), which interact with surrounding tissues such as the liver and intestines. This review briefly introduces the basic concept and classification of adipose tissue and summarizes the mechanism of alcohol affecting lipolysis and lipogenesis in WAT and BAT. The adipose tissue-liver axis is crucial in maintaining lipid homeostasis within the body. Therefore, this review also demonstrates the effects of alcohol consumption on the adipose tissue-liver axis to explore the role of alcohol consumption in the crosstalk between adipose tissue and the liver.

Thickening mechanism of recombined dairy cream stored at 4 °C: Changes in the composition and structure of milk protein under different sterilization intensities.

This work elucidates the mechanism involved in the effect of varying sterilization intensities on RDC thickening via comparative analysis of the changes in the composition and structure of RDC interfacial protein after storage at 4 °C and at 25 °C. The results showed that pasteurized RDCs (75 °C for 16 s, 90 °C for 5 min) and high-temperature sterilized RDCs (105 °C for 3 min, 115 °C for 7 min and 121 °C for 7 min) did not thicken during storage at 25 °C, and had lower viscosities and higher Ca2+ concentrations than those stored at 4 °C. Whey protein (WP) aggregates were found to have been adsorbed at the interface of high-temperature treated RDCs stored at 4 °C, leading to the aggregation of fat globules and, consequently, reversible thickening. However, high-temperature sterilized RDCs underwent into irreversible thickening at 10 d, 7 d and 3 d. This phenomenon was attributed to the large amount of heat-induced whey protein and κ-casein complex that was absorbed on the oil-water interface, with Ca2+ bonded to form bridging flocculation, which altered the secondary structure of the interfacial protein to one with increased ß-sheet content and decreased random coil content.

Bioactivity of Dietary Polyphenols: The Role in LDL-C Lowering.

Cardiovascular diseases are the leading causes of the death around the world. An elevation of the low-density lipoprotein cholesterol (LDL-C) level is one of the most important risk factors for cardiovascular diseases. To achieve optimal plasma LDL-C levels, clinal therapies were investigated which targeted different metabolism pathways. However, some therapies also caused various adverse effects. Thus, there is a need for new treatment options and/or combination therapies to inhibit the LDL-C level. Dietary polyphenols have received much attention in the prevention of cardiovascular diseases due to their potential LDL-C lowering effects. However, the effectiveness and potential mechanisms of polyphenols in lowering LDL-C is not comprehensively summarized. This review focused on dietary polyphenols that could reduce LDL-C and their mechanisms of action. This review also discussed the limitations and suggestions regarding previous studies.

Ethyl acetate subfractions from ethanol extracts of fermented oats (Avena sativa L.) exert anti-cancer properties in vitro and in vivo through G2/M and S Phase arrest and apoptosis.

Background: Cancer is a major public problem and poses a long-term impact on patients' life, work, and study. Oats are widely recognized as healthy food and fermented oats were rich in the higher contents of polyphenols. However, the role of fermented oats in cancer remains elusive. Methods: The effect of ethyl acetate subfractions (EASs) from ethanol extracts of oats fermented by Rhizopus oryzae 3.2751 on cancer cells was verified by series experiments in vitro and in vivo. The cell viability, colony formation, cell cycle, apoptosis, reactive oxygen species (ROS), mitochondrial membrane potential (MMP), and western blot were determined in vitro. The toxicity of EASs and xenograft mouse model were performed in vivo. Results: MTT assay indicated that EASs interference suppressed the proliferation of four human cancer cells in a dose-dependent manner without a significant impact on two normal cells. EASs (0.2, 0.4, and 0.8 µg/mL) resulted in the G2/M and S phase arrest, apoptosis, depolarization of MMP, and ROS generation in HepG2 cells by flow cytometry. p53, JNK, caspase-9, and caspase-3 were activated and the expression of Bax was promoted, while the expression of Bcl-2 was reduced in HepG2 cells exposed to EASs via western blot. Furthermore, the in vivo study using a xenograft mouse model demonstrated that EASs attenuated the tumor growth with low systemic toxicity. Conclusions: EASs exhibited anti-cancer activities in vitro and in vivo via cell cycle arrest and apoptosis. This finding suggests that polyphenol-enriched composition from fermented oats might become a promising candidate for impeding the development and progression of liver cancer.

Essential oil, juice, and ethanol extract from bergamot confer improving effects against primary dysmenorrhea in rats.

Primary dysmenorrhea (PD) is one of the most common gynecological disorders among young women. Bergamot is rich in natural bioactive ingredients, which could potentially ameliorate PD. We aimed to investigate whether the bergamot products (essential oil, juice, and ethanol extract) could improve PD induced by estradiol benzoate and oxytocin. The rats were supplemented with the three doses of bergamot products and positive drugs by gastric perfusion, respectively. The results demonstrated that bergamot products could alleviate PD with dose-dependence via inhibiting the growth of PGF2α /PGE2 ratio, accumulation of MDA, and release of iNOS, and promoting the activities of T-AOC, SOD, CAT, and GSH in uterine tissues. Furthermore, bergamot products could mitigate the writhing response and histopathological alterations in uterine tissues. In addition, bergamot essential oil had greater benefits than the corresponding dose of juice and ethanol extract. PRACTICAL APPLICATIONS: An increasing number of young women suffered PD, severely impacting their life. Seeking a healthy diet therapy can effectively avoid the adverse effects of PD drugs. Bergamot as natural fruit is rich in several bioactive ingredients. This study reported the function of bergamot products for alleviating PD via regulating the levels of prostaglandins and inflammatory mediator, and the capacities of antioxidants. This research provides insights for the development of functional foods with improving effect against PD. It also offers us a theoretical basis for the reasonable application of different forms of bergamot products.

Effects of Huangjiu, Baijiu and Red Wine Combined With High-Fat Diet on Glucose and Lipid Metabolism: Aggravate or Alleviate?

AIM: To compare effects on certain health indices in rodents of different doses of alcoholic beverages, huangjiu (Chinese yellow wine), red wine and baijiu (Chinese liquor) combined with high-fat diet (HFD) and the pure HFD. METHODS: A total of 80 rats were randomly divided into eight groups and treated with (a) basal diet (3.5 kcal/g); (b) HFD (19.5% w/w lard, 4.5 kcal/g) and (c) HFD with low or high doses of separate alcoholic beverages (2.5 and 5 g/kg ethanol, respectively) for 28 weeks. RESULTS: Chronic drinking when combined with HFD was associated with reduced body weight, fat accumulation and serum TNF-α level, serum TG, TC and LDL-C levels, and improved glucose tolerance (OGTT) and insulin sensitivity (ITT), hepatic enzymes; elevated levels or activities of the antioxidant enzymes like superoxide dismutase, catalase and glutathione reductase, reduced the content of lipid peroxidation productions such as malondialdehyde, in comparison with the pure HFD intake. In addition, compared with HFD, drinking plus HFD improved microbiota dysbiosis, down-regulated the ratio of Firmicutes/Bacteroidetes and promoted the growth of some probiotics including Prevotellaceae_UCG-001 and norank_f__Bacteroidales_S24-7_group. CONCLUSION: Overall, the three beverages showed different impacts on indicators but red wine showed the most 'beneficial' effects. Of course, higher ethanol dosages can be expected to cause overall negative health effects, and harms of high fat intake can be prevented by healthier diet.

Essential Oil and Juice from Bergamot and Sweet Orange Improve Acne Vulgaris Caused by Excessive Androgen Secretion.

Acne vulgaris is one of the most common chronic inflammatory skin diseases. Bergamot and sweet orange are rich in nutritional and functional components, which exhibit antioxidant, anti-inflammatory, and antiapoptotic effect. The aim of this study was to evaluate the potential effect of bergamot and sweet orange (juice and essential oil) on acne vulgaris caused by excessive secretion of androgen. Eighty male golden hamsters were randomly divided into 10 groups and received low or high dose of bergamot and sweet orange juice and essential oil, physiological saline, and positive drugs for four weeks, respectively. Results showed that all interventions could improve acne vulgaris by reducing the growth rate of sebaceous gland spots, inhibiting TG accumulation, decreasing the release of inflammatory cytokines (notably reducing IL-1α levels), promoting apoptosis in the sebaceous gland, and decreasing the ratio of T/E2. Among them, bergamot and orange essential oil may have better effects (dose dependent) on alleviating acne vulgaris than the corresponding juice. In view of the large population of acne patients and the widespread use of sweet orange and bergamot, this study is likely to exert an extensive and far-reaching influence.

Wheat Flour, Enriched with γ-Oryzanol, Phytosterol, and Ferulic Acid, Alleviates Lipid and Glucose Metabolism in High-Fat-Fructose-Fed Rats.

(1) Background: Modern dietary patterns with a high intake of fat and fructose, as well as refined carbohydrates, closely relate to lipid/glucose metabolic disorders. The main objective of this study is to provide new thoughts in designing functional food with some lipid/glucose metabolism regulating effects for obese people. (2) Methods: The alleviating abilities of γ-oryzanol, phytosterol or ferulic acid-enriched wheat flour on lipid/glucose metabolic dysfunction were evaluated in male SD rats induced by a high-fat-fructose diet. The underlying mechanisms were clarified using western blot. (3) Results: In an in vitro cell model, γ-oryzanol, phytosterol and ferulic acid regulate lipid/glucose metabolism by increasing the phosphorylation of AMPK and Akt, and PI3K expression, as well as decreasing expressions of DGAT1 and SCD. The in vivo study shows that ferulic acid and γ-oryzanol-enriched flours are beneficial for managing body weight, improving glucose metabolism, hyperlipidemia and hepatic lipid accumulation. Phytosterol-enriched flour exerted remarkable effects in regulating hyperinsulinemia, insulin resistance and hyperuricemia. Western blot analysis of proteins from liver samples reveals that these enriched flours alleviated hepatic lipid accumulation and insulin resistance through their elevation in the phosphorylation of AMPK and Akt. (4) Conclusions: Our study indicates that these enriched flours can serve as a health-promoting functional food to regulate obesity-related lipid/glucose metabolic dysfunction in rats.

Protective Effects of Five Structurally Diverse Flavonoid Subgroups against Chronic Alcohol-Induced Hepatic Damage in a Mouse Model.

Alcoholic liver disease (ALD) has become one of the major global health problems, with augmented morbidity and mortality. Evidence indicates that flavonoids can reduce the risk of ALD owing to their biological properties. However, the effect of structurally different flavonoid subclasses on alleviating alcohol-induced liver damage in a same model has never been studied. In this study, mice were supplemented with five kinds of flavonoid subgroups, apigenin (flavone), quercetin (flavonol), naringenin (flavanone), (-)-epigallocatechin gallate (flavanol), and genistein (isoflavone), in the same dose (0.3 mmol kg-1 body weight) and then given 50% alcohol by gastric perfusion for five consecutive weeks. The results demonstrated that genistein and naringenin had greater benefits in terms of mitigating fibrosis and apoptosis, respectively, in the liver. Lipid deposition, partial inflammatory-related factors (nuclear factor kappa B p65, cyclooxygenase-2, and interleukin-6 levels), and hepatic histopathological alterations were similarly attenuated by five kinds of flavonoids. All the flavonoids also showed different degrees of influence on protecting against alcoholic liver injury on other aspects, such as serum biochemistry makers, hepatic lipid accumulation, lipid peroxidation, antioxidant capacities, and inflammation.

Structurally Different Flavonoid Subclasses Attenuate High-Fat and High-Fructose Diet Induced Metabolic Syndrome in Rats.

Metabolic syndrome is a serious health problem worldwide. Increasing evidence indicates that flavonoid-rich foods exert beneficial effects. However, the function of flavonoids in metabolic syndrome is controversial. Here, we focus on the structural effects of flavonoids by comparing the effect of five purified subclasses of flavonoids on high-fat and high-fructose diet (HFFD) induced metabolic syndrome in vivo. Sprague-Dawley (SD) rats were fed with (i) basal diet (3.21 kcal/g) (ii) HFFD (25% lard and 25% fructose, 4.70 kcal/g), and (iii) HFFD with flavonoids representing different subclasses (2.6 mmol/kg diet): apigenin (flavones), quercetin (flavonols), genistein (isoflavones), naringenin (flavanones), and epigallocatechin gallate (flavanols) for 13 weeks. Our results showed that structurally different flavonoid subclasses prevented the HFFD-induced metabolic syndrome. Apigenin significantly decreased adipose fat and leptin levels and increased adiponectin levels. Epigallocatechin gallate and naringenin were both effective on dyslipidemia and hepatic lipid accumulations. The proinflammatory cytokines TNF-α and IL-6 were alleviated by quercetin, genistein, and naringenin. All the flavonoids exerted significant functions on improving insulin resistance and fasting glucose. In conclusion, flavonoid subclasses structurally exert antihyperlipidemic, antidiabetic, and anti-inflammatory functions by attenuating the lipid metabolism, glucose metabolism, and inflammation of metabolic syndrome.

Bioactive, nutritional composition, heavy metal and pesticide residue of four Chinese jujube cultivars.

This study aims to conduct a detailed investigation on four cultivars grown in northwest China, concentrating on the analysis of the bioactive contents, nutrients, heavy metal concentrations, and pesticide residue contents. Those Chinese jujubes consist of 51.99-71.75% edible part, 82.35-89.63% carbohydrates, 4.43-6.01% protein, 0.48-0.63% lipid, 2.80-4.80% polysaccharide, 45.64-88.97 mg/100 g ascorbic acid, 132.16-196.58 mg/100 g phenolics and 101.17-132.04 mg/100 g flavonoids in dry matter. In those four Chinese jujube cultivars, sulfur amino acids are the first limiting amino acids for adults, and aromatic amino acids are for children. The amount of heavy metal and pesticide residue concentrations in those jujubes was way below the limit. All four cultivars were found to have different nutritional values except for the carbohydrates; they had higher rates of carbohydrates and polysaccharide than those previously reported ones from Eastern China; and they are a better source for carbohydrates, vitamin C and functional amino acids.

Stability of a type 2 diabetes rat model induced by high-fat diet feeding with low-dose streptozotocin injection.

OBJECTIVE: The present study aims at determining the stability of a popular type 2 diabetes rat model induced by a high-fat diet combined with a low-dose streptozotocin injection. METHODS: Wistar rats were fed with a high-fat diet for 8 weeks followed by a one-time injection of 25 or 35 mg/kg streptozotocin to induce type 2 diabetes. Then the diabetic rats were fed with regular diet/high-fat diet for 4 weeks. Changes in biochemical parameters were monitored during the 4 weeks. RESULTS: All the rats developed more severe dyslipidemia and hepatic dysfunction after streptozotocin injection. The features of 35 mg/kg streptozotocin rats more resembled type 1 diabetes with decreased body weight and blood insulin. Rats with 25 mg/kg streptozotocin followed by normal diet feeding showed normalized blood glucose level and pancreatic structure, indicating that normal diet might help recovery from certain symptoms of type 2 diabetes. In comparison, diabetic rats fed with high-fat diet presented decreased but relatively stable blood glucose level, and this was significantly higher than that of the control group (P<0.05). CONCLUSIONS: This model easily recovers with normal diet feeding. A high-fat diet is suggested as the background diet in future pharmacological studies using this model.

Cyanidin-3-glucoside Alleviates 4-Hydroxyhexenal-Induced NLRP3 Inflammasome Activation via JNK-c-Jun/AP-1 Pathway in Human Retinal Pigment Epithelial Cells.

Recently, the NLRP3 inflammasome activation in the eyes has been known to be associated with the pathogenesis of age-related macular degeneration. The aim of this study was to investigate the protective effects of cyanidin-3-glucoside (C3G), an important anthocyanin with great potential for preventing eye diseases, against 4-hydroxyhexenal- (HHE-) induced inflammatory damages in human retinal pigment epithelial cells, ARPE-19. We noticed that C3G pretreatment to the ARPE-19 cells rescued HHE-induced antiproliferative effects. Cell apoptosis ratio induced by HHE was also decreased by C3G, measured by flow cytometry. The activation of NLRP3 inflammasome induced by HHE was found with increases of caspase-1 activity, proinflammatory cytokine releases (IL-1ß and IL-18), and NLRP3 inflammasome-related gene expressions (NLRP3, IL-1ß, IL-18, and caspase-1). The C3G showed potent inhibitive effects on these NLRP3 inflammasome activation hallmarks induced by HHE. Moreover, we noticed that the C3G's pretreatment leads to a delayed and a decreased JNK activation in HHE-challenged ARPE-19 cells. Finally, using a luciferase reporter gene assay system, we demonstrated that HHE-induced activation protein- (AP-) 1 transcription activity was abolished by C3G pretreatment in a dose-dependent manner. Taken together, these data showed that HHE leads to inflammatory damages to ARPE-19 cells while C3G has great protective effects, highlighting future potential applications of C3G against AMD-associated inflammation.

Dietary supplementation with omega-3 polyunsaturated fatty acid-rich oils protects against visible-light-induced retinal damage in vivo.

The effects of administering omega-3 (ω-3) polyunsaturated fatty acid (PUFA)-rich oils on visible-light-induced retinal damage were investigated in rabbits. The mole percentages of α-linolenic acid in sea buckthorn berry oil, sea buckthorn oil (SO), sea buckthorn seed oil and flaxseed oil (FO) were 2.12%, 12.98%, 31.56% and 55.41%, respectively. Algal oil (AO) contains 33.34% docosahexaenoic acid. SO has the highest total phenolic content (63.42 ± 0.59 mg SAE per 100 g) amongst these oils. The administration of SO, FO and AO provided structural and functional protection to the retina. In the retina, we observed a significant increase in the levels of DHA in the AO group compared with the normal group. The mechanism of retinal protection by SO, FO and AO involves up-regulating the expression of nuclear factor erythroid-2 related factor 2 and haem oxygenase-1. The levels of interleukin-1 ß, tumour necrosis factor-alpha, interleukin-8, and cyclooxygenase 2 in the retina were significantly reduced with AO treatment. The administration of AO resulted in the down-regulation of nuclear factor kappa B mRNA expression. In addition, the treatment with AO significantly attenuated the light-induced apoptosis and angiogenesis in the retina. These results suggest that dietary ω-3 PUFA-rich oils protect against visible-light-induced retinal damage.

Antioxidant capacity and amino acid profile of millet bran wine and the synergistic interaction between major polyphenols.

Millet bran, the by-product of millet processing industry, contains an abundance of phytochemicals, especially polyphenols. The main objective of this study was brewing antioxidant wine from millet bran, as well as the nutritional evaluation. The total polyphenol content of wine samples was determined by Folin-Ciocalteu colorimetric method, and the antioxidant capacity was evaluated by DPPH radical-scavenging capacity, Trolox equivalent antioxidant capacity (TEAC), and ferric reducing antioxidant power (FRAP). Results showed that millet bran wine (MBW) contained as much as six times of total polyphenols compared with millet wine (MW), and performed considerably stronger antioxidant activity in DPPH, TEAC and FRAP assays. More than sixfold of total amino acids (AA) were found in MBW than in MW. Moreover, the indispensable AA and functional AA were also abundant in MBW. The major polyphenol compounds in MBW were identified using HPLC, including vanillic acid, syringic acid (SA), p-coumaric acid (CA) and ferulic acid (FA). They exhibited synergism in the antioxidant assays, especially the combinations of SA and CA, SA and FA. This study not only provides evidence for MBW as a nutraceutical with antioxidant activity, but also opens new avenues in the area of making comprehensive utilization of agricultural by-products.

Comparative analysis of oxidative mechanisms of phloroglucinol and dieckol by electrochemical, spectroscopic, cellular and computational methods.

Numerous studies have been carried out on the redox activities of phenolic compounds from terrestrial plants, however, the redox pathway of phlorotannins, a type of marine algae-derived polyphenol, is far from clear. In the present study, the redox mechanisms of two phlorotannins, phloroglucinol (PL) and dieckol (DL), were comparatively scrutinized. Differential pulse voltammetry was conducted in the pH range 2.0-12.0 to determine the acid-base dissociation constant (pK a) and the number of electrons and protons involved in the redox reactions of two phlorotannins. Cyclic voltammetry was applied to obtain the heterogeneous electron transfer rate constant (k 0). By means of computational calculation, UV-vis spectroscopy, and electrochemical analysis, it is proposed that PL oxidation in the whole pH range undergoes two steps which are dominated by proton-coupled electron transfer (PCET) (pH ≤ 9) and sequential proton-loss electron transfer (SPLET) mechanisms (pH > 9), respectively. In contrast, the multiple steps taking place in the DL oxidation process rely on PCET (pH ≤ 5), mixed SPLET/PCET (5 < pH ≤ 10), and electron transfer (pH > 10) mechanisms, respectively. Also, the lower proton affinity and ionization potential values of DL, which are attributed to its conjugated Cπ-O-Cπ moieties, lead to relatively higher redox activity as compared to PL in various chemical and cellular models. These findings may provide useful insights into the oxidative conversion of phlorotannins in their biological and chemical processes.

Potential Retinal Benefits of Dietary Polyphenols Based on Their Permeability across the Blood-Retinal Barrier.

Whether all dietary polyphenols nourish the eyes via oral supplementation is controversial. Given that passage of dietary polyphenols across the blood-retina barrier (BRB) is the precondition for polyphenols to exhibit ocular benefits, the BRB permeability of polyphenols was assessed in this study. Being common dietary polyphenols in fruits and vegetables, nonanthocyanin flavonoids, anthocyanins, and phenolic acids were investigated. BRB was simulated in vitro by using a differentiated retinal pigment epithelial cell monolayer cultivated on a Transwell culture system. Penetration rate was calculated by quantitatively analyzing the polyphenols in basolateral media. The BRB permeability of different polyphenols obviously (p < 0.05) differed, as follows: phenolic acids > nonanthocyanin flavonoids > anthocyanins. Glycosylation and methylation improved the BRB permeability of nonanthocyanin flavonoids and anthocyanins. However, instability and carbonylation at the C-4 position severely suppressed the BRB permeability of anthocyanins and nonanthocyanin flavonoids. Moreover, a new metabolite was discovered during penetration of anthocyanins into the BRB. However, hydrophilic phenolic acids exhibited better BRB permeability than hydrophobic ones. Data demonstrate that BRB permeability of polyphenols was determined based on structural characteristics, hydrophilicity, stability, and metabolic changes.

Preparation of monoclonal antibody and development of an indirect competitive enzyme-linked immunosorbent assay for ornidazole detection.

A monoclonal antibody (mAb) and an indirect competitive enzyme-linked immunosorbent assay (ic-ELISA) for ornidazole (ONZ) detection were developed. ONZ was conjugated with cationic bovine serum albumin as a hapten to generate the artificial immunogens and coating antigens. BALB/c mice were immunized, and mAbs were obtained. The competitive inhibition curve of ic-ELISA was y=0.0438x2-0.2101x+0.2925, with R2=0.9941. The 50% inhibition concentration, the limit of detection, and limit of quality for ONZ were 0.15, 0.01, and 0.05µg/kg, respectively. The cross-reactivity of the mAbs to secnidazole was 0.33%. The recoveries were from 89.18% to 101.63% and the coefficient of variation was less than 7.15% in chicken, chicken liver, and honey samples, all of which had ONZ concentrations of 0.05 and 0.1µg/kg. Results showed that the ic-ELISA based on mAb could be used for the rapid detection for ONZ.

Protective Effects of Genistein and Puerarin against Chronic Alcohol-Induced Liver Injury in Mice via Antioxidant, Anti-inflammatory, and Anti-apoptotic Mechanisms.

This study aimed to investigate the protective effect of genistein or puerarin on chronic alcohol-induced liver injury in vivo and to explore the underlying mechanisms of hepatoprotective effects. Mice were administered genistein or puerarin (0.3 mmol kg(-1) body weight) and gastrically infused with 50% alcohol once per day for 5 weeks. Levels of serum transaminases, serum and hepatic lipids, hepatic antioxidant capacities, inflammation, apoptosis, and histopathological sections were analyzed. Results showed that genistein and puerarin exhibited similar effects in ameliorating alcohol-induced liver injury. However, genistein is more effective than puerarin in decreasing levels of malondialdehyde (1.05 ± 0.0947 vs 1.28 ± 0.213 nmol/mg pro, p < 0.05), tumor necrosis factor α (3.12 ± 0.498 vs 3.82 ± 0.277 pg/mg pro, p < 0.05), interleukin-6 (1.46 ± 0.223 vs 1.88 ± 0.309 pg/mg pro, p < 0.05), whereas puerarin is more effective than genistein in ameliorating serum activities or levels of alanine transaminase (35.8 ± 3.95 vs 42.6 ± 6.56 U/L, p < 0.05) and low-density lipoprotein cholesterol (1.12 ± 0.160 vs 1.55 ± 0.150 mmol/L, p < 0.05). In conclusion, both genistein and puerarin effectively alleviate hepatic damage induced by chronic alcohol administration through potential antioxidant, anti-inflammatory, or anti-apoptotic mechanisms.
