High glucose reduces Nrf2-dependent cRAGE release and enhances inflammasome-dependent IL-1βproduction in monocytes:the modulatory effects of EGCG

Soluble receptor for advanced glycation end products(sRAGE)acts as a decoy sequestering of RAGE ligands,thus preventing the activation of the ligand-RAGE axis linking human diseases.However,the molecular mechanisms underlying sRAGE remain unclear.In this study,THP-1 monocytes were cultured in normal glucose(NG,5.5 mmol/L)and high glucose(HG,15 mmol/L)to investigate the effects of diabetesrelevant glucose concentrations on sRAGE and interleukin-1β(IL-1β)secretion.The modulatory effects of epigallocatechin gallate(EGCG)in response to HG challenge were also evaluated.HG enhanced intracellular reactive oxygen species(ROS)generation and RAGE expression.The secretion of sRAGE,including esRAGE and cRAGE,was reduced under HG conditions,together with the downregulation of a disintegrin and metallopeptidase 10(ADAM10)and nuclear factor erythroid 2-related factor 2(Nrf2)nuclear translocation.Mechanistically,the HG effects were counteracted by siRAGE and exacerbated by siNrf2.Chromatin immunoprecipitation results showed that Nrf2 binding to the ADAM10 promoter and HG interfered with this binding.Our data reinforce the notion that RAGE and Nrf2 might be sRAGE-regulating factors.Under HG conditions,the treatment of EGCG reduced ROS generation and RAGE activation.EGCG-stimulated cRAGE release was likely caused by the upregulation of the Nrf2-ADAM10 pathway.EGCG inhibited HG-mediated NLRP3 inflammasome activation at least partly by stimulating sRAGE,thereby reducing IL-1βrelease.

Structural insights on anti-biofilm mechanism of heated slightly acidic electrolyzed water technology against multi-resistant Staphylococcus aureus biofilm on food contact surface

Slightly acidic electrolyzed water(SAEW)has proven to be an efficient and novel sanitizer in food and agriculture field.This study assessed the efficacy of SAEW(30 mg/L)at 40℃on the inactivation of foodbome pathogens and detachment of multi-resistant Staphylococcus aureus(MRSA)biofilm.Furthermore.the underlying mechanism of MRS A biofilm under heated SAEW at 40℃treatment on metabolic profiles was investigated.The results showed that the heated SAEW at 40℃significantly effectively against foodbome pathogens of 1.96-7.56(lg(CFU/g))reduction in pork,chicken,spinach,and lettuce.The heated SAEW at 40℃treatment significantly reduced MRS A biofilm cells by 2.41(lg(CFU/cm^(2))).The synergistic effect of SAEW treatment showed intense anti-biofilm activity in decreasing cell density and impairing biofilm cell membranes.Global metabolic response of MRSA biofilms,treated by SAEW at 40℃,revealed the alterations of intracellular metabolites,including amino acids,organic acid,fatty acid,and lipid.Moreover,signaling pathways involved in amino acid metabolism,energy metabolism,nucleotide synthesis,carbohydrate metabolites,and lipid biosynthesis were functionally disrupted by the SAEW at 40℃treatment.As per our knowledge,this is the first research to uncover the potential mechanism of heated SAEW treatment against MRSA biofilm on food contact surface.

Effects of Enteromorpha prolifera polysaccharides on growth performance,intestinal barrier function and cecal microbiota in yellow-feathered broilers under heat stress

Background Global warming leading to heat stress(HS)is becoming a major challenge for broiler production.This study aimed to explore the protective effects of seaweed(Enteromorpha prolifera)polysaccharides(EPS)on the intestinal barrier function,microbial ecology,and performance of broilers under HS.A total of 144 yellow-feathered broilers(male,56 days old)with 682.59±7.38 g were randomly assigned to 3 groups:1)TN(thermal neutral zone,23.6±1.8℃),2)HS(heat stress,33.2±1.5℃ for 10 h/d),and 3)HSE(HS+0.1%EPS).Each group contained 6 replicates with 8 broilers per replicate.The study was conducted for 4 weeks;feed intake and body weights were measured at the end of weeks 2 and 4.At the end of the feeding trial,small intestine samples were collected for histomorphology,antioxidant,secretory immunoglobulin A(s Ig A)content,apoptosis,gene and protein expression analysis;cecal contents were also collected for microbiota analysis based on 16S r DNA sequencing.Results Dietary EPS promoted the average daily gain(ADG)of broilers during 3–4 weeks of HS(P<0.05).At the end of HS on broilers,the activity of total superoxide dismutase(T-SOD),glutathione S-transferase(GST),and the content of s Ig A in jejunum were improved by EPS supplementation(P<0.05).Besides,dietary EPS reduced the epithelial cell apoptosis of jejunum and ileum in heat-stressed broilers(P<0.05).Addition of EPS in HS group broilers'diet upregulated the relative m RNA expression of Occludin,ZO-1,γ-GCLc and IL-10 of the jejunum(P<0.05),whereas downregulated the relative m RNA expression of NF-κB p65,TNF-αand IL-1βof the jejunum(P<0.05).Dietary EPS increased the protein expression of Occludin and ZO-1,whereas it reduced the protein expression of NF-κB p65 and MLCK(P<0.01)and tended to decrease the protein expression of TNF-α(P=0.094)in heat-stressed broilers.Furthermore,the proportions of Bacteroides and Oscillospira among the three groups were positively associated with jejunal apoptosis and pro-inflammatory cytokine expression(P<0.05)and negatively correlated with jejunal Occludin level(P<0.05).However,the proportions of Lactobacillus,Barnesiella,Subdoligranulum,Megasphaera,Collinsella,and Blautia among the three groups were positively related to ADG(P<0.05).Conclusions EPS can be used as a feed additive in yellow-feathered broilers.It effectively improves growth performance and alleviates HS-induced intestinal injury by relieving inflammatory damage and improving the tight junction proteins expression.These beneficial effects may be related to inhibiting NF-κB/MLCK signaling pathway activation and regulation of cecal microbiota.

The feasibility study of natural pigments as food colorants and seasonings pigments safety on dried tofu coloring

In order to improve appetite,attract consumers and even conform to the food culture,food coloring has become one of the necessary links in modern food processing.For example,dried-tofu will be colored by adding artificial food colors(AFCs)such as sunset yellow,cochineal red A or other seasonings like soy sauce.However,the dispute persists about whether AFCs are harmful to health.Some studies indicate AFCs affect children’s intelligence and attention,cause hyperactivity,and allergy when children consumed≥50 mg.In addition,researches showed that chemical soy sauce produces a trace of methylglyoxal(MGO)in the manufacturing process,which is related to diseases such as oxidative stress,diabetes,and cognitive deterioration.Therefore,natural pigments are relatively new and promising strategy for replacing high-risk AFCs.Thus,the objective of this study was to use dried-tofu as a natural colorants coloring screening platform,through the concept of three primary colors to discuss the coloring effects of natural colorants in Taiwan in double–phase(liquid phase to solid phase)food coloring system and assess the effects of MGO on PC12 neuron cellular morphology and cell cycle at the dietary exposure in soy sauce.Our results showed that formula G:R=0.2:0.8 and C:R=0.08:0.92 were coloring by combined natural colorants had the same eye sensory quality acceptance of consumer and had the intention to purchase.Furthermore,the results from the PC12 cell suggested that dietary exposure of methylglyoxal(<50M)in soy sauce did not affect neuron cellular morphology and cell cycle significantly.Overall,Gardenia Yellow,Curcumin,and Radish Red could overcome the application restrictions in multiplephase food coloring system and simultaneously soy sauce as a coloring agent was safety.It showed the possibility of them as food colorants on dried-tofu.

Inhibitory activities of microalgal fucoxanthin againstα-amylase,α-glucosidase, and glucose oxidase in 3T3-L1cells linked to type 2 diabetes

Postprandial hyperglycemia is an early indication of type 2 diabetes and the target of many anti-diabetic and anti-obesity studies.α-Glucosidase and α-amylase are the crucial factors in regulating starch digestion and glucose absorption,making them key targets for many studies to treat postprandial hyperglycemia.We studied the inhibitory activities of microalgal fucoxanthin against rat-intestinalα-glucosidase and pancreaticα-amylase along with the antidiabetic eff ect to induce diff erentiation in 3T3-L1 pre-adipocytes using Oil Red-O staining.Fucoxanthin displayed strong hindrance activities towardα-amylase in a concentration-dependent manner,with an IC50 value of 0.68mmol/L,whereas weak inhibitory activity against α-glucosidase,with an IC 50 value of 4.75 mmol/L.Fucoxanthin also considerably elevated glucose oxidase activity in 3T3-L1 cells by 31.3%at 5μmol/L.During adipocyte differentiation,fucoxanthin showed lipid accumulation in 3T3-L1 cells with no cytotoxicity up to 20μmol/L.However,fucoxanthin had no inhibitory activity on glucose-6-phosphate dehydrogenase.These results suggest that fucoxanthin might be useful for the prevention of obesity or diabetes by inhibiting carbohydrate-hydrolyzing enzymes and lipid accumulation and be utilized as an ingredient for a functional food or dietary supplement.

Lower serum folate is associated with development and invasiveness of gastric cancer

AIM: To evaluate the associations of serum folate levelwith development, invasiveness and patient survival of gastric cancer. METHODS: In this nested case-control study, patients with newly diagnosed gastric cancer undergoing gastrectomy were enrolled, and patients receiving chemotherapy prior to surgery, with other concurrent malignancy, or of the aboriginal and alien populations were excluded. In total, 155 gastric cancer patients and 149 healthy controls were enrolled for determination of serum folate levels and their correlation with gastric cancer. Using the median value of serum folate computed among the overall population as the cutoff value, the associations between serum folate and gastric cancer in all cases and different age and gender subgroups were analyzed by multivariate logistic regression analysis. In the patient cohort of gastric cancer, receiver-operating characteristic analyses were performed to calculate the best cutoff values of serum folate, and the associations between serum folate levels and clinicopathological features were further analyzed by multivariate regression analysis. Survival analyses were conducted using the Cox proportional hazards model.RESULTS: The mean serum folate level was significantly lower in gastric cancer patients than that in controls(3.71 ± 0.30 ng/mL vs 8.00 ± 0.54 ng/mL, P < 0.01), and folate levels were consistently lower in gastric cancer patients regardless of age and gender(all P < 0.01). Using the median serum folate value as the cutoff value, low serum folate was significantly associated with gastric cancer risk in the whole population(OR = 19.77, 95%CI: 10.54-37.06, P < 0.001) and all strata(age < 60 years OR = 17.39, 95%CI: 7.28-41.54, age ≥ 60 years(OR = 21.67, 95%CI: 8.27-56.80), males(OR = 17.95, 95%CI: 7.93-40.62), and females(OR = 20.95, 95%CI: 7.66-57.31); all P < 0.001. In the patient cohort of gastric cancer, the respective cutoff values showed that low serum folate levels were significantly associated with serosal invasion(OR = 2.54, 95%CI: 1.23-5.23), lymphatic invasion(OR = 2.23, 95%CI: 1.17-4.26), and liver metastasis(OR =6.67, 95%CI: 1.28-34.91) of gastric cancer(all P < 0.05). Serum folate level below 1.90 ng/mL was associated with poor patient survival(HR = 1.84, 95%CI: 1.04-3.27, P < 0.05) in univariate analysis.CONCLUSION: Lower serum folate levels were significantly associated with gastric cancer development and invasive phenotypes. The role of folate depletion in gastric cancer invasion warrants further study.

Ethanol extract of Oenanthe javanica increases cell proliferation and neuroblast differentiation in the adolescent rat dentate gyrus

Oenanthe javanica is an aquatic perennial herb that belongs to theOenanthe genus in Apiaceae family, and it displays well-known medicinal properties such as protective effects against glu-tamate-induced neurotoxicity. However, few studies regarding effects ofOenanthe javanica on neurogenesis in the brain have been reported. In this study, we examined the effects of a normal diet and a diet containing ethanol extract ofOenanthe javanica on cell proliferation and neu-roblast differentiation in the subgranular zone of the hippocampal dentate gyrus of adolescent rats using Ki-67 （an endogenous marker for cell proliferation） and doublecortin （a marker for neuroblast）. Our results showed thatOenanthe javanica extract signiifcantly increased the number of Ki-67-immunoreactive cells and doublecortin-immunoreactive neuroblasts in the subgranular zone of the dentate gyrus in the adolescent rats. In addition, the immunoreactivity of brain-derived neurotrophic factor was signiifcantly increased in the dentate gyrus of the Oenanthe javanica extract-treated group compared with the control group. However, we did not ifnd that vascular endothelial growth factor expression was increased in theOenanthe javanica extract-treated group compared with the control group. These results indicate thatOenanthe javanica extract improves cell proliferation and neuroblast differentiation by increasing brain-de-rived neurotrophic factor immunoreactivity in the rat dentate gyrus.

Phytochemical profiling and biological activity of Plectranthus amboinicus(Lour.) mediated by various solvent extracts against Aedes aegypti larvae and toxicity evaluation

Objective:To analyze the phytochemical compounds and to investigate the bio-toxic efficacy of various solvent extracts of Plectranthus amboinicus against mosquito larvae activity and lethality on non-targeting organisms.Methods:The methanol,ethyl acetate,hexane,and aqueous extracts of Plectranthus amboinicus were subjected to analyze the mosquitocidal activity against the dengue vector,Aedes aegypti and toxicity assays on zebra fish and brine shrimp.Three replications were performed,and negative control was also maintained.Amongst,ethyl acetate extract of Plectranthus amboinicus was chosen for the determination of bio-active compounds.Results:The mosquitocidal assays of methanol and ethyl acetate extracts of Plectranthus amboinicus showed the maximal activity with minimal concentration against the 4 th instar mosquito-larvae of Aedes aegypti through the following lethal concentration(LC50 and LC90)values:53.36&92.51μg/m L and 13.64&86.09μg/mL,respectively.In addition,the plant extracts showed no toxicity on zebra fish embryo and brine shrimp assays.The gas-chromatography analysis of the ethyl acetate extract of Plectranthus amboinicus revealed the presence of seven different compounds.Among them,PAEA-fraction 60 contained a major active bioactive compound,hexadecanoic acid,methyl ester(270.0).Conclusions:Plectranthus amboinicus possesses mosquitocidal properties and could be used as a potential alternative source for preparing the mosquitocidal agents.

Effects of A Multi-Enzyme Complex or Probiotic Supplementation on Performance and Nutrient Digestibility of Broiler Chicks

This experiment was conducted to determine whether the performance of broilers fed diets based on corn and soybean meal could be enhanced with enzymes or probiotics. A total of 120 male broilers, three days of age, were assigned to one of four treatments in a completely randomized design, and housed in groups of five with six cages per treatment. The control diet was based on corn and soybean meal while the three experimental diets consisted of the basal diet supplemented with 0.1% of enzyme I, enzyme II, or probiotic. Enzyme I provided α-galactosidase and fl-mannanase, while enzyme II provided protease, amylase, α-galactosidase, xylanase, and cellulase. The probiotic was composed of Bacillus coagulance, Bacillus lichenformis , Bacillus subtilis , and Clostridium butyricum. Over the 28 day experiment, the weight gain of birds fed the probiotic treatment was superior （P = 0.03 ） to the control, while gains for the enzyme treatments were intermediate to those of the control and probiotic. Feed intake and feed conversion did not differ among treatments （P 〉 0.05 ）. Ammonia production was significantly （ P 〈 0.01 ） higher in the control compared with either of the enzyme or probiotic treatments. Compared with the control, supplementation with enzyme H significantly reduced the digestibility of arginine, isoleucine, and lysine （P 〈 0.05 ）. In contrast, the digestibility of energy was higher （P 〈 0.01 ） for birds supplemented with enzyme II than the control. Digestibility coeffi- cients did not differ for any other parameter with the exception of energy which was significantly higher for birds fed the probiotic treatment than the control （P 〈 0.01 ）. In summary, the performance of broilers was significantly enhanced by the addition of a probiotic to the diet. However, under the conditions of this experi- ment, supplementation with a multi-enzyme complex containing either α-galactosidase and fl-mannanase or the combination of protease, amylase, galactosidase, xylanase, and cellulase failed to improve broiler performance.

Dietary protocatechuic acid ameliorates inflammation and up-regulates intestinal tight junction proteins by modulating gut microbiota in LPS-challenged piglets

Background: Weaning is one of the major factors that cause stress and intestinal disease in piglets. Protocatechuic acid(PCA) is an active plant phenolic acid which exists in Chinese herb, Duzhong(Eucommia ulmoides Oliver), and is also considered as the main bioactive metabolite of polyphenol against oxidative stress and inflammation. This study aimed to investigate the effect of PCA on growth performance, intestinal barrier function, and gut microbiota in a weaned piglet model challenged with lipopolysaccharide(LPS).Methods: Thirty-six piglets(Pig Improvement Company line 337 × C48, 28 d of age, 8.87 kg ± 0.11 kg BW) were randomly allocated into 3 treatments and fed with a basal diet(CTL), a diet added 50 mg/kg of aureomycin(AUR), or a diet supplemented with 4000 mg/kg of PCA, respectively. The piglets were challenged with LPS(10 μg/kg BW) on d 14 and d 21 by intraperitoneal injection during the 21-d experiment. Animals(n = 6 from each group) were sacrificed after being anesthetized by sodium pentobarbital at 2 h after the last injection of LPS. The serum was collected for antioxidant indices and inflammatory cytokines analysis, the ileum was harvested for detecting mRNA and protein levels of tight junction proteins by PCR and immunohistochemical staining, and the cecum chyme was collected for intestinal flora analysis using 16 S rRNA gene sequencing.Results: Dietary supplementation of PCA or AUR significantly increased the expression of tight junction proteins including ZO-1 and claudin-1 in intestinal mucosa, and decreased the serum levels of thiobarbituric acid reactive substances(TBARS) and IL-6, as compared with CTL group. In addition, PCA also decreased the serum levels of IL-2 and TNF-α(P < 0.05). Analysis of gut microbiota indicated that PCA increased the Firmicutes/Bacteroidetes ratio(P < 0.05). Spearman's correlation analysis at the genus level revealed that PCA reduced the relative abundance of Prevotella 9, Prevotella 2, Holdemanella, and Ruminococcus torques group(P < 0.05), and increased the relative abundance of Roseburia and Desulfovibrio(P < 0.05), whereas AUR had no significant effect on these bacteria.Conclusions: These results demonstrated that both PCA and AUR had protective effect on oxidative stress, inflammation and intestinal barrier function in piglets challenged with LPS, and PCA potentially exerted the protective function by modulating intestinal flora in a way different from AUR.

Immune stimulatory activity of BRP-4,an acidic polysaccharide from an edible plant,Basella rubra L.

Objective:To evaluated the immunomodulatory effect of BRP-4,an acidic polysaccharide from Basella rubra(B.rubra) L on the macrophage activity.Methods:Phagocytic activity was determined by the ingestion of Latex Beads-Rabbit IgC-FITC using the fluorescent microscopy and flow cytometry analysis and nitric oxide production was measured using Griess reaction assay.Results:An enhanced production of NO was observed at 10 and 100 μg/mL of BRP-4.The phagocytic activity of macrophage was enhanced in BRP-4 treated RAW264.7 cells.BRP-4combined with concanavalin A(Con A) provided obvious promotion and strengthening of the proliferation of the splenocytes.Conclusions:BRP-4,polysaccharide isolated from B.rubra,is suggested to activate macrophage function and stimulate splenocyte proliferation.The strong immunomodulatory activity of BRP-4 confirmed its good potential as an immunotherapeutic adjuvant.

Antioxidant effect of Lactobacillus fermentum HFY02-fermented soy milk on D-galactose-induced aging mouse model

This study aimed to investigate the antioxidant effect of soybean milk fermented by a new type of Lactobacillus fermentum(LF-HFY02)by using D-galactose induced aging mice model.Firstly,the optimal fermentation conditions was screened out by detecting the effects of different fermentation temperature and time on the active components and antioxidant activity of soybean milk in viro.And then unfermented soybean milk and the soybean milk fermented by different Lactobacillus was given by gavage to D-galactose-induced aging mouse.The activities of GSH,GSH-Px,SOD,CAT and T-AOC in serum,brain and liver of soybean milk fermented by LF-HFY02 were significantly increased,while the content of MDA and the level of AGEs in hippocampal were significantly decreased compared with D-galactose induced group.Further more,the mRNA expression of GSH and SOD in mouse liver were obviously up-regulated by soybean milk fermented by LF-HFY02.The skin tissue structure of mice in the LF-HFY02 fermented soybean milk group was more complete,the collagen fibers were increased and arranged orderly and liver inflammation has improved compared with the model group.And Western blot analysis showed that LF-HFY02 effectively upregulated EGFR,SOD and GSH protein expression in mouse liver.These findings suggest that LF-HFY02 can effectively prevent D-galactose-induced oxidation and aging in mice,and the effect was even better than that of the Lactobacillus delbruechii subsp.bulgaricus and vitamin C.Thus,LF-HFY02 may be potentially employed as a probiotic strain.In conclusion,soybean milk fermented by LF-HFY02 can increase the content of antioxidant factors and the activity of antioxidant enzymes by regulating gene and protein expression,and finally inhibit the process of tissue cell peroxidation,and improve the oxidative damage of mouse skin and liver.The results could provide a basis for the research and development and industrial production of probiotic-related fermented soybean milk products.

New perspectives on probiotics in health and disease

The gut microbiota continues to fascinate scientists in many realms when it is considered that humans contain 90%bacteria.Correlations between changes in composition and activity of the gut microbiota and common disorders such as cancer,hypertension,hypercholesterolemia,inflammatory bowel diseases,obesity,oral health,etc.have been proposed.What is the real role of probiotics,prebiotics and synbiotics in influencing a healthy microbiota?Both in vitro evidences and in vivo clinical data have supported some of these new health claims,while recent molecular advancement has provided strong indications to support and justify the hypotheses.However,probiotics validity and health claims have continuously been rejected on the basis of“biomarker deficiency”.To battle the increase in health care costs,a preventive approach to medicine with the development of probiotics and prebiotics or symbiotic products is being advanced.This review discusses the potential beneficial effects of probiotics in preventing and treating certain diseases as well as current and future perspectives of probiotic research.

Effect of Water Depth on Seasonal Variation in the Chemical Composition of Akamoku, Sargassum horneri (Turner) C. Agardh

The brown alga, Akamoku, also known as Sargassum horneri, was harvested at depths of 1 - 2 and 5 m in the oceanic areas of the Chikuzen Sea off the coast of Fukuoka, Japan, and its chemical composition (moisture, protein, lipid, ash, carbohydrate and total dietary fiber content) was investigated. The aim of this study was to elucidate the relationship between the chemical components and the growth of S. horneri as recyclable resource for a sustainable future. S. horneri at an ocean depth of 5 m grew rapidly. The biomass was abundant from January until April. After maturation and gamete release at the middle of April, plant senescence began occurring, and only short plants remained at the sea bottom. On the other hand, S. horneri at an ocean depth of 1 - 2 m grew slowly and could be harvested until early June. The protein, lipid and total dietary fiber content of S. horneri at an ocean depth of 5 m showed apparent gender-based differences.

β-GLUCOSIDASE BY THERM OPHILIC AND ANAEROBIC CLOSTRIDIOM THERMOCOPRIAE

In this report,the β-glucosidase from the C.thermocopriae JT3-3 strain was studied.By purifying,the enzyme specific activity was increased about 30 times,and the yield was about 2%.The molecular weight of β-glucosidase is 50000 by gel filtration chromatography,and about 46000 by SDS polyacrylamide eIectrophoresis.Next the effects of pH and temperature on enzyme activity were studied and the Km value for β-glucosidase was calculated from Lineweaver-Burk.In addition,we succeeded in the cloning and expression of β-glucosidase gene from C.thermocopriae to E.coli cells using pBR322 as a vector.

Physiological Mechanism of Thermotolerance in Wheat (<i>Triticum aestivum</i>Lin.) Seedlings

A research work was performed under sub-tropical condition (24&deg;8'N, 90&deg;0'E) at Bangabandhu Sheikh Mujibur Rahman Agricultural University with three wheat genotypes (BARI Gom 25, BARI Gom 26 and Pavon 76) to observe the mobilization of seed reserve and seedling growth under normal (15&deg;C/25&deg;C) and elevated (25&deg;C/35&deg;C) temperature in growth chamber. The effect of high temperature on wheat seedling was observed in terms of mobilized seed reserve, respiration and transpiration efficiency and seedling growth. At 35&deg;C temperature, maximum mobilization of seed reserve was observed in BARI Gom varieties (BARI Gom 25 and 26) but the respiration efficiency was higher in Pavon 76 in comparison to other genotypes. Maximum loss of respiration and transpiration at 35&deg;C temperature was found to produce low seedling growth in Pavon 76. It appeared from the result that at high temperature the maximum mobilized seed reserve and subsequently minimum loss of respiration and transpiration collectively contributed a positive role for better seedling growth in BARI Gom 25 and BARI Gom 26. Therefore the better mobilized seed reserve and subsequently minimum loss of respiration and transpiration during seedling development are indicators of the thermo tolerance in growing wheat seedling.

The extract of the immature fruit of Poncirus trifoliata induces apoptosis in colorectal cancer cells via mitochondrial autophagy

The immature fruits of Poncirus trifoliate are used as a medicine for the treatment of gastrointestinal disorders,inflammation,and allergies in East Asia.However,their effect on colon cancer cells remains unclear.We investigated the effect of the immature fruit of P.trifoliate extract on colorectal adenocarcinoma.The extract of the immature fruit of P.trifoliata inhibited the proliferation of CT-26 cells compared with untreated cells and it induced autophagy and apoptosis through the protein kinase B/mammalian target of rapamycin and 5'-AMP-activated protein kinase pathways.The number of autophagic vacuoles and autophage markers increased in response to the extract.At later time-points,apoptosis increased dose/time-dependently.In CT-26 cells pre-treated a pan-caspase inhibitor prior to P.trifoliata immature fruit extract treatment,we did not find any change in pro-caspase 3 and pro-PARP levels.Additionally,in cells pre-treated autphage inhibitor,SQSTM1/p62 and LC3AB,pro-caspase 3 and pro-PARP levels did not change.Our results indicate the molecular mechanisms that the extract of the immature fruit of P.trifoliata induces apoptosis in colorectal carcinoma cells by inducing mitochondrial autophagy.In this study,we provided a draft for further investigate the use of MEPT for colorectal cancer inhibition.

Effects of main active components of rosemary on growth performance,meat quality and lipid metabolism in finishing pigs

Rosemary extracts have been widely used as feed additives in recent years.This study aimed to investigate the effects of rosmarinic acid(RA)and ursolic acid(UA),the main active components of rosemary,on growth performance,meat quality and lipid metabolism in finishing pigs.A total of 72 finishing pigs(Landrace;initial age of 150 d)were randomly divided into 3 treatments with 8 replicates of 3 pigs each,and fed a basal diet or diet containing 500 mg/kg of RA or UA.The results showed that dietary supplementation of RA or UA had no significant effect on the growth performance and carcass traits of finishing pigs(P>0.05).However,both RA and UA significantly increased the triglyceride(TG)level in soleus muscle(P<0.001).Supplementation of RA increased the expression of genes related to lipogenesis and transport including fatty acid synthase(FAS)(P<0.001),sterol regulatory element binding protein-1c(SREBP1c)(P<0.001)and peroxisome proliferator-activated receptorγ(PPARγ)(P<0.05),while UA increased the expression of fatty acid transport protein 1(FATP1),a gene related to lipid uptake(P<0.05).However,RA reduced the expression of adipogenesis-related gene acetyl-coenzyme A carboxylase a(ACCa)(P<0.01).Characterization of cecal microbiota indicated that RA increased the microbial richness(chao 1,P<0.001)and diversity(observed species,P<0.01).Further analysis of the genera revealed that RA increased the relative abundance of Bacteroides and g-UCG-005(P<0.05),and UA enriched Prevotella(P<0.001).Correlation analysis showed that g-UCG-005 was positively correlated with the expression of FAS,carnitine palmitoyl transferase 1B(CPT1B),SREBP1c and PPARγ(P<0.01).In conclusion,dietary supplementation of RA or UA may increase fat deposition in muscle of finishing pigs by regulating lipid metabolism and gut microbiota.
