Maternal under-nutrition during pregnancy alters the molecular response to over-nutrition in multiple tissues in juvenile offspring.

ABSTRACT: This study examined gene expression in liver, fat and skeletal muscle of juvenile baboons to determine the effect of maternal under-nutrition (MUN; dams were fed a diet with 30% reduction in nutrients) during pregnancy on response to consumption of a high-fat, high-carbohydrate, high-salt and sugar drink (HFCS) diet for 7 weeks later in development of MUN offspring. After dietary challenge, gene expression in the liver, fat and skeletal muscle of MUN juvenile baboons was compared with that of control juvenile baboons (CON; dams were fed a control diet). Results showed that the number of differentially expressed genes and enriched pathways in these tissues differed between MUN and CON juvenile baboons.

Postnatal persistence of sex-dependent renal developmental programmed structural and molecular changes in nonhuman primates

Project description:Background: Poor nutrition during development programs kidney function. No studies on postnatal consequences of decreased perinatal nutrition exist in nonhuman primates (NHP) for translation to human renal disease. Our baboon model of moderate maternal nutrient restriction (MNR) produces intrauterine growth restricted (IUGR) and programs renal fetal phenotype. We hypothesized that the IUGR phenotype persists postnatally influencing responses to a high-fat, high-carbohydrate, high-salt (HFCS) diet. Methods: Pregnant baboons ate chow Control (CON) or 70% of control intake (MNR) from 0.16 gestation through lactation. MNR offspring were IUGR at birth. At weaning, all offspring, (control and IUGR females and males n=3/group) ate chow. At ~3.5 years age, blood, urine, and kidney biopsies were collected before and after a 7-week high HFCS diet challenge. Kidney function, unbiased kidney gene expression, and untargeted urine metabolomics were evaluated. Results: IUGR female and male kidney transcriptome and urine metabolome differed from CON at 3.5 years, prior to HFCS. After the challenge, we observed sex-specific and fetal exposure-specific responses in urine creatinine, urine metabolites, and renal signaling pathways. Conclusions: We previously showed mTOR signaling dysregulation in IUGR fetal kidneys. Before HFCS, gene expression analysis indicated that dysregulation persists postnatally in IUGR females. IUGR male offspring response to HFCS showed uncoordinated signaling pathway responses suggestive of proximal tubule injury. To our knowledge, this is the first study comparing CON and IUGR postnatal juvenile NHP and the impact of fetal and postnatal life caloric mismatch. Perinatal history needs to be taken into account when assessing renal disease risk.

Efect of neonatal nutrition on adipose tissue remodeling genes during early development and in adult mice

Project description:While the phenomenon linking the early nutritional environment to disease susceptibility exists in many mammalian species, the underlying mechanisms are unknown. We hypothesized that nutritional programming is a variable quantitative state of gene expression, fixed by the state of energy balance in the neonate, that waxes and wanes in the adult animal in response to changes in energy balance. We tested this hypothesis with an experiment, based upon global gene expression, to identify networks of genes in which expression patterns in inguinal fat of mice have been altered by the nutritional environment during early post-natal development. Gene expression patterns in inguinal fat was assessed at 5, 10, 21 days of age and as adults fed chow (56 days of age) followed by high fat diet for 8 weeks (112 days of age) for C57BL/6J mice reared by lactating dams fed either a control diet (CONT), lactating dams fed a diet in which food intake was restricted to cause under-nourishment (lactation under-nutrition; LUN); and, lactating dams fed a high fat diet in where the number of progeny was limited to four (lactation over-nutrition; LON) .

Expression data from feline liver tissue

Project description:This study looks at the effect of dietary manipulation on the development of hepatic steatosis and changes in hepatic gene expression in a feline model. We used microarray analysis to examine changes in hepatic gene transcription in response to Trans fat, High Fructose Corn Syrup (HFCS) and/or Monosodium Glutamate (MSG) in the domestic cat. The use of human Affymetrix arrays for the study of feline gene expression has previously been validated by Dowling and Bienzle, 2005, Journal of General Virology. 86(Pt 8), 2239-48 (PMID 16033971). Our study animals were bred from female Felis catus previously placed on one of 4 different dietary regimens for a period of 3 weeks prior to mating. The four dietary regimens used in this study were: [1] Standard Chow Control feline diet (Test Diet Purina catalog #5003); [2] MSG diet consisting of Control diet with 1.125% added Monosodium Glutamate (Diet A: Test Diet Purina catalog #5C1J); [3] Trans-fat/HFCS diet, containing 8.6% Trans fat and 24% HFCS (Diet B: Test Diet Purina catalog #5B4K); and [4] Trans-fat/HFCS and MSG diet, containing 8.6% Trans fat, 24% HFCS and 1.125% MSG (Diet C: Test Diet Purina catalog #5C1H). Following mating, the 4 groups of dams were maintained on their respective diets throughout the gestation and nursing period. Male offspring used in the following experiments were weaned onto the same diets and maintained on their respective dietary regimens until they reached 9 months of age. Hepatic tissues (4-5 per diet group) were used for RNA extraction and hybridization on Affymetrix microarrays.

MicroRNA signature in skeletal muscle in insulin resistant rats

Project description:The current study aimed to address the hypothesis that programmed expression of key miRNAs in skeletal muscle mediates the development of insulin resistance, and consequently long-term health. We thus examined microRNA signatures in skeletal muscle of programmed insulin resistant rats offspring from high fat-fed dams vs control offspring from chow fed dams. Skeletal muscle (soleus) was collected from the hind limb of 1 year old male offspring (6 from control dams, 6 from high fat-fed dams) . Ramaciotti Centre for Genomics (UNSW, sydney, Australia)

Maternal Nutrition Induces Pervasive Gene Expression Changes but no Detectable DNA Methylation Differences in the Liver of Adult Offspring [RRBS]

Project description:Aims: Epidemiological and animal studies have shown that maternal diet can influence metabolism in adult offspring. However, the molecular mechanisms underlying these changes remain poorly understood. Here, we aim to explore phenotypes induced by maternal obesity in a mouse model and examine gene expression and epigenetic alterations in adulthood induced by maternal diet. Methods: We analyzed genetically identical male mice born from dams fed a high- or low-fat diet throughout pregnancy and until day 21 postpartum. After weaning, half of the males of each group were fed a high-fat diet, the other half a low-fat diet. We first characterized the genome-wide gene expression patterns of six tissues of adult offspring - liver, pancreas, white adipose, brain, muscle and heart [GSE40903] . We then measured DNA methylation patterns in liver at selected loci and throughout the genome. Results: Maternal diet had a significant effect on the body weight of the offspring when they are fed an obesogenic diet after weaning. Our analyses showed that maternal diet had a pervasive effect on gene expression, with a pronounced effect in liver where it affected many genes involved in inflammation, cholesterol synthesis and RXR activation. Maternal diet had no detectable effect on DNA methylation in the liver. Conclusions: Overall, our findings highlighted the persistent influence of maternal diet on adult tissue regulation and suggested that the transcriptional changes were unlikely to be caused by DNA methylation differences in adult liver. Methylation is compared between nine week old animals fed a common diet as adults, but derived from mothers fed different diets.

Transcription profiling of liver and white adipose tissue from mice fed standard or test diets with or without monosodium glutamate in their water

Project description:C57BL/6J mice were from The Jackson Laboratory (Maine, USA) and were housed/caged and fed a standard chow diet until 6 weeks of age whereupon they were placed in one of 4 different dietary regimens for a period of 3 weeks prior to mating. Mice were housed under pathogen-free conditions of 21± 1°C, 40 to 60% humidity, and a 12 h-12 h light/dark cycle. The 4 diet regimens used in this study were: [1] ad lib Standard Chow (Control diet) with ad lib drinking water. [2] Ad lib Standard Chow, with ad lib drinking water containing 0.64 mg/ml (97 mg/Kg body weight) monosodium glutamate (MSG diet). [3] Ad lib Test Diet Purina 5001 with 20% 55-HFCS (5B4K, Purina, USA), and ad lib drinking water (HFCS diet). [4] Ad lib Purina 5001 with 20% 55-HFCS, and ad lib drinking water containing 0.64 mg/ml (97 mg/K body weight) monosodium glutamate (HFCS+MSG diet). See Table 1 for diet composition. Following mating, the 4 groups of dams were maintained on their respective diets throughout the gestation and nursing period. Male offspring used in these experiments were weighed, then weaned onto the same diets and maintained in this regimen until they reached either 16 or 32 weeks of age. Total RNA was prepared from the liver and visceral white adipose tissue (WAT) taken from 16-week-old mice in the 4 different diet groups using Qiagen RNeasy Kit (Qiagen USA) according to the manufacturers instructions and stored at -80 o C.<br>
