Milk- and soy-based diets have differential effects on colitis and colon gene expression in the Il10-/- mouse

ABSTRACT: Milk and soy are reported to contain bioactive molecules with antibacterial and immunomodulatory actions, which may be beneficial to people with IBD. The aim of this study was to determine whether diets containing ruminant milk or soy solids reduce intestinal inflammation in Il10-/- mice. Male Il10-/- mice and C57BL/6J mice were fed diets containing 40% (w/w) sheep, goat, or cow whole milk powder, 40% (w/w) soy solids (NOW® Foods Soy Milk Powder, Instant), or one of two control diets (casein-free modified-AIN76A or standard AIN76A) from 4 to 11 weeks of age. Diets were based on AIN76A, which was included as an inter-experimental control for inflammation. For all diets except AIN76A, total protein, fat, carbohydrate and energy were kept as similar as possible. Weight and food intake were measured throughout the experiment (three times weekly), and intestinal tissue was taken for histopathology evaluation of inflammation and analysis of gene expression. Analysis of mouse weight and feed intake both showed a significant strain-diet interaction: Il10-/- mice fed the cow and goat milk diets ate less and gained less weight than all the other diet groups. This diet effect was not evident for the C57BL/6J mice. Il10-/- mice on the cow and goat milk diets had reduced colon histological injury scores relative to those on the other diets. Il10-/- mice on the cow and goat milk diets also had reduced expression of many immune/inflammatory-related genes and pathways.

Different Diets Change the Bovine Milk Extracellular Vesicle-miRNA Expression

Project description:Given that different diets could alter cow milk yield and composition, the effects of different feed formula on milk extracellular vesicle (EV) miRNAs were detected. Cow milk EVs contained various small RNAs, including miRNAs, snRNAs, tiRNAs, Cis-regulatory elements, and piRNAs. Two hundred and seventy-six known bos taurus miRNAs were identified by sequencing in bovine milk EVs. There were 13 immune-related miRNAs in the top 20 miRNAs in milk EVs. Nine differently expressed known miRNAs were detected in responding to different feed formulations. Cow milk EVs are abundant of small RNAs, especially miRNAs, which might be closely related to the development of maternal mammary gland and neonatal immune maturity.

Real-time quantitative PCR analysis of goat mammary glands in peak-lactation and late-lactation periods

Project description:In comparison with cow milk, goat (Capra hircus) milk contains much higher levels of unsaturated fatty acids, as well as higher levels of total fat, proteins, carbohydrates, calcium, and vitamins.The main objective of the present study was to better define the relationship of known miRNAs regulating milk fat metabolism. Our main purpose is to search for some known miRNAs regulating milk fat metabolism, to this end, we screened potential miRNAs with differential expression between peak-lactation and non-lactation.

Transcription profiling by array of pig liver from neonatal pigs fed milk and soy formula

Project description:The majority of babies in the US are formula-fed instead of breast fed. There are major differences in the composition of formulas and breast milk and yet little is known about metabolic differences in babies as the result of feeding these very different diets and how that might affect development or disease risk in later life. One concern is that soy-based formulas might have adverse health effects in babies as a result of the presence of low levels of estrogenic phytochemicals genistein and daidzein which are normally present in soy beans. In the current study, we used a piglet model to look at this question. Piglets were either fed breast milk from the sow or were fed two different infant formulas (cow's milk-based or soy-based) from age 2 days to 21 days when pigs are normally weaned onto solid food. Blood glucose and lipids were measured. Formula-fed pigs were found to have lower cholesterol than breast fed piglets and in addition had larger stores of iron in their liver.Microarray analysis was carried out to see if changes in liver gene expression could explain these effects of formula feeding. It was found that overall gene expression profiles were influenced by formula feeding compared to breast fed neonates. Gender-independent and unique effects of formula influenced cholesterol and iron metabolism. Further, soy formula feeding in comparison to milk-based formula failed to reveal any estrogenic actions on hepatic gene expression in either male or female pigs. Piglets (female, male) were either fed breast milk from the sow or were fed two different infant formulas (cow's milk-based or soy-based) from age 2 days to 21 days when pigs are normally weaned onto solid food.

The role of dietary leucine and dairy protein on hepatic gene expression

Project description:We used microarray to determine the differences in hepatic gene expression for diet-induced obese Sprague-Dawley rats consuming different dietary proteins. Proteins of interest included skim milk powder (dairy), casein, and the branched-chain amino acid, leucine. The primary aims of this study were: (i) to compare the effects of diets with protein derived from casein, casein supplemented with leucine, and complete dairy on body composition and insulin sensitivity; and (ii) to determine if there is a synergistic effect of dietary Ca and protein source on body composition and insulin sensitivity. Secondarily, we used microarray analysis to examine the effect of casein, leucine, or complete dairy containing diets on the expression of hepatic genes related to lipid and glucose metabolism. Diet induced obese rats consumed ad libitum, a high fat, high sucrose diet for 8 weeks (n=4). All diets had an energy density of 4.6 kcal/gram and provided 10% of total energy from protein [casein, complete dairy (skim milk powder), or leucine-supplemented casein (7.1% from casein plus 2.9% from leucine)]. The casein treatment was the control diet.

Exogenous miRNA expression profiling in serum of pig and rat fed with different diets

Project description:We performed carefully designed and controlled animal feeding studies. We devided 9 adult rats in three group and each group fed with one type of diets in 28 days: rice, potatoes and chow. We fed piglets in triplicate either with cow milk or let them feed from sows milk for 4 weeks followed by 7 weeks of maize diet. Based on the small RNA sequencing data from 9 rat and 6 pig serum samples, we detected no transfer of plant miRNAs into rat blood, or bovine milk sequences into piglet blood.

Metabonomic analysis of human and 12 kinds of livestock mature milk

Project description:<p>Mature milk, as a nutrient-rich endogenous metabolite, has various beneficial effects on the human body. In order to investigate the specific nutrients provided by different dairy products to humans, we used UHPLC-Q-TOF MS to analyze the highly significantly differentially expressed metabolites in 13 species of mammalian mature milk, which were grouped into 17 major metabolite classes with 1992 metabolites based on chemical classification. KEGG shows that 5 pathways in which differentially significant metabolites are actively involved are ABC transporters, Purine metabolism, Pyrimidine metabolism, Phosphotransferase system, Galactose metabolism. The study found that pig milk and goat milk are closer to human milk and contain more nutrients that are beneficial to human health, followed by camel milk and cow milk. In the context of dairy production, the development of goat milk is more likely to meet human needs and health.</p>
