Diets rich in whole grains increase betainized compounds associated with glucose metabolism.

BACKGROUND: Epidemiologic evidence suggests that diets rich in whole grains are associated with a reduced risk of developing chronic diseases and all-cause mortality. However, the molecular mechanisms behind these beneficial metabolic effects are poorly understood. OBJECTIVE: Our aim was to investigate novel trimethylated (betainized) compounds from mice and humans, and their association with whole grain-rich diets and insulin resistance and insulin secretion. DESIGN: Fasting plasma samples were obtained in a mouse (C57BL/6J male) feeding trial and a controlled dietary intervention. The mous

A Novel Combination of Wheat Peptides and Fucoidan Attenuates Ethanol-Induced Gastric Mucosal Damage through Anti-Oxidant, Anti-Inflammatory, and Pro-Survival Mechanisms.

Gastritis or peptic ulcer is believed to affect about half of people worldwide. Traditional medications can lead to adverse effects, therefore, alternative nutritional strategies are needed to prevent the development of gastric mucosal damage. A novel combination of two food-grade ingredients, wheat peptides and fucoidan (WPF), was prepared to treat male Sprague Dawley rats for 30 days before gastric mucosal damage was induced by oral administration of ethanol. The serum levels of biomarkers were determined by enzyme-linked immunosorbent assay. Biomarkers in stomach tissue were analyzed using

A phenazine-1-carboxylic acid producing polyextremophilic Pseudomonas chlororaphis (MCC2693) strain, isolated from mountain ecosystem, possesses biocontrol and plant growth promotion abilities.

The genus Pseudomonas is known to comprise a huge diversity of species with the ability to thrive in different habitats, including those considered as extreme environments. In the present study, a psychrotolerant, wide pH tolerant and halotolerant strain of Pseudomonas chlororaphis GBPI_507 (MCC2693), isolated from the wheat rhizosphere growing in a mountain location in Indian Himalayan Region (IHR), has been investigated for its antimicrobial potential with particular reference to phenazine production and plant growth promoting traits. GBPI_507 showed phenazine production at the temperatures

Conservation and diversity of gene families explored using the CODEHOP strategy in higher plants.

BACKGROUND: Availability of genomewide information on an increasing but still limited number of plants offers the possibility of identifying orthologues, or related genes, in species with major economical impact and complex genomes. In this paper we exploit the recently described CODEHOP primer design and PCR strategy for targeted isolation of homologues in large gene families. RESULTS: The method was tested with two different objectives. The first was to analyze the evolution of the CYP98 family of cytochrome P450 genes involved in 3-hydroxylation of phenolic compounds and lignification in a

Local immune response to food antigens drives meal-induced abdominal pain.

Up to 20% of people worldwide develop gastrointestinal symptoms following a meal1, leading to decreased quality of life, substantial morbidity and high medical costs. Although the interest of both the scientific and lay communities in this issue has increased markedly in recent years, with the worldwide introduction of gluten-free and other diets, the underlying mechanisms of food-induced abdominal complaints remain largely unknown. Here we show that a bacterial infection and bacterial toxins can trigger an immune response that leads to the production of dietary-antigen-specific IgE antibodies

Dietary wheat amylase trypsin inhibitors promote features of murine non-alcoholic fatty liver disease.

We previously demonstrated that a common dietary protein component, wheat amylase trypsin inhibitors (ATI), stimulate intestinal macrophages and dendritic cells via toll like receptor 4. Activation of these intestinal myeloid cells elicits an inflammatory signal that is propagated to mesenteric lymph nodes, and that can facilitate extraintestinal inflammation. Mice were fed a well-defined high fat diet, with (HFD/ATI) or without (HFD) nutritionally irrelevant amounts of ATI. Mice on HFD/ATI developed only mild signs of intestinal inflammation and myeloid cell activation but displayed significa

Predicted efficacy of the Palestinian wheat flour fortification programme: complementary analysis of biochemical and dietary data.

OBJECTIVE: To utilize complementary biochemical and dietary data collected before the initiation of national flour fortification to (i) identify micronutrient insufficiencies or deficiencies and dietary inadequacies in Palestinian women and children in vulnerable communities and (ii) assess the suitability of the current wheat flour fortification formula. DESIGN: Quantitative dietary intake questionnaires were administered and fasting venous blood samples collected in randomly selected households in Gaza City and Hebron. The impact of fortification was simulated by estimating the additional m

Rapid mobilization of membrane lipids in wheat leaf sheaths during incompatible interactions with Hessian fly.

Hessian fly (HF) is a biotrophic insect that interacts with wheat on a gene-for-gene basis. We profiled changes in membrane lipids in two isogenic wheat lines: a susceptible line and its backcrossed offspring containing the resistance gene H13. Our results revealed a 32 to 45% reduction in total concentrations of 129 lipid species in resistant plants during incompatible interactions within 24 h after HF attack. A smaller and delayed response was observed in susceptible plants during compatible interactions. Microarray and real-time polymerase chain reaction analyses of 168 lipid-metabolism-rel

Influence of early nutritional components on the development of murine autoimmune diabetes.

BACKGROUND/AIMS: Infant diet is suggested to modify autoimmune diabetes risk. The aim of this study was to determine whether infant food components affect diabetes development in the nonobese autoimmune diabetes (NOD) mouse. METHODS: A basal low-diabetogenic diet was identified by feeding litter-matched female NOD mice standardized diets with and without casein and wheat proteins after weaning. In subsequent trials, basal diet with supplements of wheat (5, 10 and 30%), gluten, wheat globulin/albumin, corn (5%), potato (5%), apple (5%) or carrot (5%) was fed to litter-matched female NOD mice a

Evaluating the bio-application of biomacromolecule of lignin-carbohydrate complexes (LCC) from wheat straw in bone metabolism via ROS scavenging.

Lignin-carbohydrate complexes (LCC) arebiomacromolecules that can be obtained from different biomass. Even some works have shown the LCC can efficiently scavenge the intracellular and endogenous reactive oxygen species (ROS), while little work has been carried out to investigate the potential application of LCC for ROS-related treatment in biological filed, especially for the treatment of periprosthetic osteolysis in vivo. In this work, Lignin-rich (LCC-A) and carbohydrate-rich (LCC-B) fractions in wheat straw are isolated and used as the ROS scavenger to promote osteoblast differentiation and

Nutritional Wheat Amylase-Trypsin Inhibitors Promote Intestinal Inflammation via Activation of Myeloid Cells.

BACKGROUND & AIMS: Wheat amylase-trypsin inhibitors (ATIs) are nutritional activators of innate immunity, via activation of the toll-like receptor 4 (TLR4) on myeloid cells. We aimed to characterize the biologic activity of ATIs in various foods and their effect on intestinal inflammation. METHODS: We selected 38 different gluten-containing and gluten-free products, either unprocessed (such as wheat, rye, barley, quinoa, amaranth, soya, lentils, and rice) or processed (such as pizza, pasta, bread, and biscuits). ATIs were extracted and their biological activities determined in TLR4-responsive

Effect of Avemar and Avemar + vitamin C on tumor growth and metastasis in experimental animals.

Because of the observed immunostimulatory actions of a new fermented wheat germ extract--with standardized benzoquinone composition--we have investigated the eventual tumor growth- and metastasis-inhibiting effects of this preparation (Avemar) applied alone or in combination with vitamin C. Tumor models of different origin [a highly metastatic variant of the Lewis lung carcinoma (3LL-HH), B16 melanoma, a rat nephroblastoma (RWT-M) and a human colon carcinoma xenograft (HCR25)]--kept in artificially immunosuppressed mice were applied. The metastasis-inhibiting effects of the treatments have bee

[Non-celiac gluten sensitivity: a critical review of current evidence].

Non-celiac gluten sensitivity (NCGS) is an emerging disorder characterized by intestinal and extra-intestinal symptoms related to the ingestion of gluten-containing food in non-celiac patients. Its prevalence has been estimated to be six to ten-times higher than that of celiac disease (CD). A gluten-free diet is the most widely recommended therapy, but the causative agent remains unknown and there are no consensus diagnostic criteria. Recent studies on NCGS have included patients with possibly overlooked minor CD and diarrhea-predominant irritable bowel syndrome without self-reported gluten in

Wheat amylase trypsin inhibitors drive intestinal inflammation via activation of toll-like receptor 4.

Ingestion of wheat, barley, or rye triggers small intestinal inflammation in patients with celiac disease. Specifically, the storage proteins of these cereals (gluten) elicit an adaptive Th1-mediated immune response in individuals carrying HLA-DQ2 or HLA-DQ8 as major genetic predisposition. This well-defined role of adaptive immunity contrasts with an ill-defined component of innate immunity in celiac disease. We identify the α-amylase/trypsin inhibitors (ATIs) CM3 and 0.19, pest resistance molecules in wheat, as strong activators of innate immune responses in monocytes, macrophages, and dendr

A rapid induction by elicitors of the mRNA encoding CCD-1, a 14kDa Ca2+ -binding protein in wheat cultured cells.

Intracellular Ca(2+) has been implicated in the signal transduction processes during the development of the plant defense system against fungal pathogens. From wheat cultured cells that had been treated with the elicitor derived from Typhula ishikariensis, the ccd-1 gene encoding a 14 kDa Ca(2+)-binding protein with an acidic amphiphilic feature was isolated. The ccd-1-encoded protein (CCD-1) shares homology to the C-terminal half domain of centrin, a Ca(2+)-binding protein conserved in eukaryotes. Unlike typical eukaryotic centrins, CCD-1 contains only one Ca(2+)-binding loop, which correspon

Characterization of wheat Bell1-type homeobox genes in floral organs of alloplasmic lines with Aegilops crassa cytoplasm.

BACKGROUND: Alloplasmic wheat lines with Aegilops crassa cytoplasm often show homeotic conversion of stamens into pistils under long-day conditions. In the pistillody-exhibiting florets, an ectopic ovule is formed within the transformed stamens, and female sterility is also observed because of abnormal integument development. RESULTS: In this study, four wheat Bell1-like homeobox (BLH) genes were isolated and named WBLH1 to WBLH4. WBLH1/WBLH3/WBLH4 expression was observed in the basal boundary region of the ovary in both normal pistils and transformed stamens. WBLH2 was also strongly expresse

Cloning, functional expression, and characterization of CYP709C1, the first sub-terminal hydroxylase of long chain fatty acid in plants. Induction by chemicals and methyl jasmonate.

We cloned and characterized CYP709C1, a new plant cytochrome P450 belonging to the P450 family, that so far has no identified function except for clustering with a fatty acid metabolizing clade of P450 enzymes. We showed here that CYP709C1 is capable of hydroxylating fatty acids at the omega-1 and omega-2 positions. This work was performed after recoding and heterologous expression of a full-length cDNA isolated from a wheat cDNA library in an engineered yeast strain. Investigation on substrate specificity indicates that CYP709C1 metabolizes different fatty acids varying in their chain length

Elicitor- and A23187-induced expression of WCK-1, a gene encoding mitogen-activated protein kinase in wheat.

Wheat cultured cells were used to study the role of Ca2+ in regulating protein kinases during the induction of defense-related genes by fungal elicitor treatments. Manipulation of intracellular Ca2+ concentrations by treatment with calcium ionophore A23187 in the presence of high extracellular Ca2+ resulted in the induction of mRNA expression of WCK-1, a gene encoding mitogen-activated protein (MAP) kinase. The induction of WCK-1 mRNA by A23187 did not occur when extracellular Ca2+ was chelated by 1,2-bis(2-aminophenoxy)ethane-N,N,N',N'-tetraacetic acid (BAPTA). The WCK-1 mRNA was also induced

Оценка стабильности жажды в пальчиках (Eleusine coracana L.) с использованием многовариантных подходов.

Пальцы, как правило, выращиваются в полузасушливых тропиках, где они выращиваются главным образом фермерами-добытчиками. Однако урожайность зерна остается низкой из-за сложного количественного характера этой особенности и ее низкой наследственности. Таким образом, взаимодействие генотипа х с окружающей средой (ГЭИ) оказывает значительное влияние на производство. В этом исследовании изучается воздействие ГЭИ на качество генотипов пальца в различных средах, при этом особое внимание уделяется чувствительности урожая к изменчивости климата. Цель этого исследования заключалась в оценке воздействия

Suppressive Effects of Arriheuk Wheat Sprout Extract on Muscle Atrophy in Dexamethasone-Induced C2C12 Myotubes and a Mouse Model.

Skeletal muscle atrophy refers to the loss of muscle strength and mass due to decreased protein synthesis or increased protein degradation. Various conditions can cause muscle atrophy, including aging, heart disease, chronic illness, obstructive pulmonary disease, kidney failure, diabetes, AIDS, cancer, sepsis, and steroid use. Various natural materials have been studied for the prevention of muscle atrophy. In this study, we found that extracts from the sprouts of purple wheat, Arriheuk, prevented muscle atrophy in vitro and in vivo. Arriheuk wheat sprouts extract inhibited the expression of
