Soy protein concentrate mitigates markers of colonic inflammation and loss of gut barrier function in vitro and in vivo
Whereas a number of studies have examined the effects of soy isoflavones and tocopherols on colonic inflammation, few have examined soy protein. We determined the radical scavenging and cytoprotective effects of soy protein concentrate (SPC) in vitro and its anti-inflammatory effects in dextran sulfate sodium (DSS)-treated mice. Cotreatment with SPC protected Caco-2 human colon cells from H2O2 induced cell death and mitigated intracellular oxidative stress. Treatment of differentiated Caco-2 cells with SPC blunted DSS-induced increases in monolayer permeability. (Source: The Journal of Nutritional Biochemistry)

Oleuropein Aglycone Enhances UCP1 Expression in Brown Adipose Tissue in High-Fat-Diet-Induced Obese Rats by Activating β-Adrenergic Signalling
Oleuropein is the pungent principle of raw olives. Oleuropein aglycone (OA) is a major phenolic compound in extra virgin olive oil and the absorbed form of oleuropein.We aimed to determine the mechanism underlying the nutritional effects of oleuropein and OA on interscapular brown adipose tissue (IBAT) in rats with high-fat (HF) diet-induced obesity by examining the agonistic activity of oleuropein and OA toward the transient receptor potential ankyrin 1 (TRPA1) and vanilloid 1 (TRPV1).Four-week-old-male Sprague –Dawley rats were fed a HF (palm oil 30% wt:wt) diet alone or with oleuropein (HF-O, 1 g/kg diet) for 28 d. (S...

Salmosan ®, a β-galactomannan-rich product, in combination with Lactobacillus plantarum contributes to restore intestinal epithelial barrier function by modulation of cytokine production
Mannan-oligosaccharides (MOS) are mannose-rich substrates with several intestinal health-promoting properties. The aim of this study was to investigate the potential capacity of Salmosan ® (S-βGM), a β-galactomannan-rich MOS product, to restore epithelial barrier function independently from its capacity to reduce bacterial invasion. In addition, the combination of S-βGM with the proven probiotic Lactobacillus plantarum (LP) was also tested. Paracellular permeability was assessed by transepithelial electrical resistance (TER) in co-cultures of Caco-2 cells and macrophages (differentiated from THP-1 cells) stimulated wit...

Folate deficiency affects dendritic cell function and subsequent T helper cell differentiation
Insufficient folate status may be related to the increasing prevalence of immune- or inflammation-related chronic diseases. To investigate the effects of folate on immune regulation, we examined the impact of folate deficiency (FD) on dendritic cell (DC) maturation and function, and thus T helper (Th) cells differentiation. First, bone marrow-derived DCs (BMDCs) were generated from BALB/c mice bone marrow cells cultured in folate-containing (F-BMDCs) or folate-deficient (FD-BMDCs) medium. FD-BMDC displayed more immature phenotype including reduced levels of major histocompatibility complex class II (MHC II), co-stimulatory...

Polyphenolics from mango (Mangifera indica L.) suppress breast cancer ductal carcinoma in situ proliferation through activation of AMPK pathway and suppression of mTOR in athymic nude mice
The objective of this study was to assess the underlying mechanisms of mango polyphenol decreased cell proliferation and tumor volume in ductal carcinoma in situ breast cancer. We hypothesized that mango polyphenols suppress signaling along the AKT/mTOR axis while upregulating AMPK. To test this hypothesis, mango polyphenols (0.8 mg gallic acid equivalents/day) and pyrogallol (0.2 mg/day) were administered for 4 weeks to mice xenografted with MCF10DCIS.com cells subcutaneously (n=10 per group). Tumor volumes were significantly decreased, both mango and pyrogallol groups displayed greater than 50% decreased volume compared ...

Histone deacetylase 9 plays a role in the anti-fibrogenic effect of astaxanthin in hepatic stellate cells
Activation of hepatic stellate cells (HSCs) is critical for liver fibrosis development. Previously, we showed that astaxanthin (ASTX), a xanthophyll carotenoid, has anti-fibrogenic effects in LX-2 cells, a human HSC cell line. We sought to determine the effect of ASTX on HSC activation, and to identify molecular mediators that are critically involved in the processes. ASTX prevented the activation of mouse primary HSCs, as evidenced by attenuated induction of procollagen type I α1. In human primary HSCs, ASTX also inhibited transforming growth factor β1 (TGFβ1)-induced fibrogenic gene expression. (Source: The Journal of...

Effect of Dry Tomato Peel Supplementation on Glucose Tolerance, Insulin Resistance, and Hepatic Markers in Mice Fed High-Saturated-Fat/High-Cholesterol Diets
Many studies have investigated the effect of crude tomato peel in vivo, but no studies have determined the dose-effect of dry tomato peel (DTP) on glucose intolerance, insulin resistance, and atherogenic dyslipidemia induced by a high-saturated-fat diet in vivo. The aim of this study was to investigate the effects of different doses of DTP on the levels of oxidative stress in mice fed a high-saturated-fat and cholesterol-rich diet for 12 weeks. The main outcomes are glucose and insulin tolerance, plasma lipids, and hepatic steatosis and inflammation. (Source: The Journal of Nutritional Biochemistry)

Intestinal multidrug resistance-associated protein 2 is down-regulated in fructose-fed rats
Expression and activity of jejunal multidrug resistance-associated protein 2 (Mrp2) and glutathione-S-transferase (GST) were examined in fructose fed Wistar rats, an experimental model of metabolic syndrome. Animals were fed on (i) control diet or (ii) control diet plus 10% w/vol fructose in the drinking water. Mrp2 and the α class of GST proteins as well as their corresponding mRNAs were decreased, suggesting a transcriptional regulation by fructose. Confocal microscopy studies reaffirmed down-regulation of Mrp2. (Source: The Journal of Nutritional Biochemistry)

A naturally occurring mixture of tocotrienols inhibits the growth of human prostate tumor, associated with epigenetic modifications of cyclin-dependent kinase inhibitors p21 and p27
Tocotrienols, members of the vitamin E family, have three unsaturated bonds in their side chains. Recently, it has been suggested the biological effects of tocotrienols may differ from that of tocopherols. Several in vitro studies have shown that tocotrienols have stronger anti-cancer effects than tocopherols. VCaP cell line used in this study is from a vertebral bone metastasis from a patient with prostate cancer. Eight-week-old male NCr( −/−) nude mice were subcutaneously injected with VCaP-luc cells in matrigel and then administered a tocotrienol mixture for 8 weeks.

Human milk oligosaccharide effects on intestinal function and inflammation after preterm birth in pigs
Human milk oligosaccharides (HMOs) may mediate prebiotic and anti-inflammatory effects in newborns. This is particularly important for preterm infants who are highly susceptible to intestinal dysfunction and necrotizing enterocolitis (NEC). We hypothesized that HMO supplementation of infant formula (IF) improves intestinal function, bacterial colonization, and NEC resistance immediately after preterm birth, as tested in a preterm pig model. Mixtures of HMOs were investigated in intestinal epithelial cells and in preterm pigs (n=112) fed IF supplemented without (CON) or with a mixture of four HMOs (4-HMO) or>25 HMOs (25-HMO...

A high fat diet temporarily renders Sod1-deficient mice resistant to an oxidative insult
Patients with non-alcoholic fatty liver disease (NAFLD) may subsequently develop non-alcoholic steatohepatitis (NASH) after suffering from a second insult, such as oxidative stress. Aim of this study was to investigate the pathogenesis of the liver injury caused when lipids accumulate under conditions of intrinsic oxidative stress using mice that are deficient in superoxide dismutase 1 (SOD1) and the leptin receptor (Lepr). We established Sod1 −/−::Leprdb/db mice and carried out analyses of four groups of genetically modified mice, namely, wild type, Sod1−/−, Leprdb/db, and Sod1−/−::Leprdb/db mice. (Source: The...

Liver BCATm transgenic mouse model reveals the important role of the liver in maintaining BCAA homeostasis
Unlike other amino acids, the branched chain amino acids (BCAAs) largely bypass first pass liver degradation due to a lack of hepatocyte expression of the mitochondrial branched chain aminotransferase (BCATm). This sets up interorgan shuttling of BCAAs and liver-skeletal muscle cooperation in BCAA catabolism. To explore whether complete liver catabolism of BCAAs may impact BCAA shuttling in peripheral tissues, the BCATm gene was stably introduced into mouse liver. Two transgenic mouse lines with low and high hepatocyte expression of the BCATm transgene (LivTg-LE and LivTg-HE) were created and used to measure liver and plas...
