Project description:Mice and diets. One-month-old male mice of the long-lived B6C3F1 strain were purchased from Harlan (Indianapolis, IN) and maintained as described after weaning (15). Mice were housed in groups of 4 per cage and fed a non-purified diet, PMI Nutrition International Product #5001 (Purina Mills, Richmond, IN). At 5 months of age, the mice were individually housed, and randomly assigned to one of two groups, control (CON) or long-term CR (LTCR). CON mice were fed 93 kcal per week of a defined control diet (AIN-93M, Diet No. F05312, BIO-SERV). LTCR mice were fed 52.2 kcal per week of a defined CR diet (AIN-93M 40% Restricted, Diet No. F05314, BIO-SERV). The LTCR mice consumed approximately 40% fewer calories than mice in the CON mice. The CR diet was enriched so that the CR mice consumed approximately the same amount of protein, vitamins, and minerals per gram body weight as the control mice. Experimental design. At 20 months of age, cohorts of mice in the CON group were randomly assigned to one of 7 experimental groups (Fig. 1). A CON group continued to be fed 93 kcal per week of control diet for 8 weeks. A CR8 group was fed 77 kcal per week of CR diet for 2 weeks, followed by 52.2 kcal per week of CR diet for 6 weeks. The remaining dietary groups were fed the control diets containing, respectively, metformin (MET; Sigma, St. Louis, MO), glipizide (GLIP; Sigma), GLIP plus MET (GM), rosiglitazone (ROS; Avandia, SmithKline Beecham) or soy isoflavone extract (SOY; NOVASOY 400, Life Extension Foundation) for 8 weeks at the dosages indicated in Table 1. The drugs were mixed with powdered control diet and cold-pressed into one gram pellets (BIO-SERV Inc.). At 0900, all mice were fed 2/7 of the weekly allotment of food on Monday and Wednesday and 3/7 on Friday. The mice had free access to acidified tap water. They were fasted for 48 hours and killed by cervical dislocation at 22 months of age. No signs of pathology were detected in the animals used for the studies reported (n=4 per group). Organs were removed rapidly, flash frozen, and stored in liquid nitrogen. The weights of the mice were monitored bi-weekly. Mouse weights are given in Table 1. Measurement of specific mRNA levels. Liver total RNA was isolated as described from livers of pathology-free mice in each group (n=4 per group) (13). mRNA levels were measured using Affymetrix mouse U74Av2 arrays according to standard Affymetrix protocols (Affymetrix). Probe set expression measurement and normalization. After hybridization and scanning, raw image files were converted to probe set data (*.CEL files) using Microarray Suite (MAS 5.0). Probe set data from all 32 arrays were simultaneously analyzed with the Robust multichip Average (RMA) method to generate normalized expression measures for each probe set (Fig. 2; Ref. 24) The data were further filtered to exclude probe data sets that were “Absent” across all 32 arrays according to the MAS 5.0 detection algorithm (1,47).

Project description:Background. Steer progeny suckled by cows fed a dried distillers grains and solubles (DDGS) diet the first three months of lactation were heavier during feedlot finishing and had significantly lower marbling and larger longissumus muscles than steer suckled by cows fed a control diet (CON). These differences were profound in that progeny were managed and fed identically from weaning until finishing, and suggested that the developmental program of muscle composition was established during the suckling period. Purpose. Transcriptomes of longissimus muscle were measured using next generation sequencing to investigate whether there were any developmental clues to the differences in marbling scores and muscle content between steers suckled by DDGS (n=5) versus control (CON; n=5) diet fed cows during lactation. Methods. Multiparous Angus × Simmental cows with male progeny were fed one of two diets supplemented with either DDGS or soybean meal (CON), from calving until day 129 postpartum (PP). After conclusion of the treatments at 129 days postpartum, cow–calf pairs were comingled and managed as one group until weaning at 219 days postpartum. Steers were then transitioned to a common diet. Longissimus muscle (LM) biopsies were obtained from steers suckled by cows fed DDGS (n=5) and CON (n=5) 10 d prior to slaughter. RNA was extracted from LM. Total RNA isolated and Library Prep Kit was used to generate library for measuring messenger RNA molecules. Library was sequenced on an Illumina HiSeq2500 platform. FastQC (v 0.10.1) was used to assess sequence quality, and quality trimming was done using FASTX toolkit (v 0.0.13). Bases with less than Phred33 score of 30 were removed and resulted in reads of at least 50 bases. Reads were mapped against the bowtie2-indexed Bos taurus genome using Tophat (v 2.0.9) with default parameters, and the genome annotation file (.gtf) from Ensembl was used to associate the genome with annotated features. Raw read counts of each sample for each gene feature were generated with HTSeq (v 0.5.3p7) using Tophat output and Bos taurus annotations. Counts were merged using custom perl scripts and used for downstream differential gene expression (DE) analysis. DE pairwise analysis between samples CON and DDGS was done with ‘R’ (Version 2.15.2). Counts matrix, library sizes, and experimental design were combined to create an object using edgeR (v 3.0.3) package. Results. Number of reads per sample ranged from 79,530,352 to 58,600,824. After trimming there were 77,569,706 to 57,307,614 per sample. The percent of reads that mapped to bovine genome per sample ranged from 77.3 to 92.3%, and averaged 86.3% across all samples. Number of reads per gene ranged from one to over two-hundred ninety thousand counts per million (CPM) reads. There were 809 genes differentially expressed (P-adj<0.1) between CON and DDGS muscle. Of these 637 were upregulated and 172 downregulated in DDGS relative to CON. Overall the DDGS versus CON muscle transcriptomic signature was pro-myogenic and anti-adipogenic. In particular, myokines/satellite cell maintenance factors were found among upregulated (LIF, CNTF, FGFB1, EPHB1) genes. The anti-adipogenic signature was typified by the upregulation of anti-inflammatory cytokines and receptors (IL1RAP, IL1RL2, IL13RA2, IL1F10,), and downregulation of expression of inflammation/inflammatory cytokines and receptor (TNF, IL6R CXCL9), which suggests a selection of differentiation pathways away from adipogenic line. While the upregulation of TGFB, SPP1 and INHBA supports selection of fibroblast lineage of cells. Conclusion. The lactation phase of production can effect meat quality by affecting transcriptional signatures that favor myogenesis and depress inflammation.

Project description:In this study we sought to determine how hepatocyte-specific PPARgamma expression regulates hepatic gene expression in normal (healthy) mice fed a LFCF diet, or mice that were fed a HFCF diet for 24 weeks to induce non-alcoholic steatohepatitis (NASH). Specifically, we used chow-fed adult (10 week-old) PPARgamma floxed male mice and injected them with AAV8-TBG-Cre to knockout PPARgamma in hepatocytes (KO). A subset of PPARgamma floxed mice were injected with AAV8-TBG-Null to generate controls (C). Two weeks after AAV injections, half of the mice in each group were fed a low fat, cholesterol and fructose (LFCF) diet, or a high fat, cholesterol and fructose (HFCF) diet for 24 weeks. Livers were collected at the end of the study to assess hepatic gene expression with RNA-seq (performed by Novogen, Inc.)

Project description:F344 rats were divided into 4 groups: vehicle control, DEN, DEN+CLO and CLO. After one week of basal diet, rats belonging to the groups DEN and DEN+CLO underwent intraperitoneal injection of DEN (30mg/kg body weight) dissolved in NaCl 9‰. The two other groups were injected with NaCl 9‰ alone. At 30mg/kg, DEN is non-necrogenic thus only exhibiting initiating properties. Twelve days after injection, diet from rats belonging to the groups CLO and DEN+CLO was changed for diet containing 5000ppm CLO for up to 608 days. Series of 5 rats from each group were necropsied at days 18, 46, 102, 264, 377, 447 (reverse phase from day 377: no more CLO in the diet for rats belonging to the DEN+CLO group), and for the CLO and Control group 524, and 608 days after the injection of DEN or saline. From day 524, half of the CLO-treated rats were kept on basal diet (reverse phase) until day 608. Keywords = Clofibric acid Keywords = Diethylnitrosamine Keywords = Rat Keywords: other

Project description:Background: The age-related loss of muscle mass significantly contributes to the development of chronic diseases, loss of mobility and dependency on others, yet could be improved by an optimized lifestyle. Objective: The goal of this randomized controlled trial was to compare the influence of a habitual diet (CON) with either a diet containing the recommended protein intake (RP) or a high protein intake (HP), both with and without strength training, on the plasma proteome in older adults. Methods: 136 women and men (65-85 years) were randomly assigned to three intervention groups. CON continued their habitual diet; participants of the HP and RP group consumed either high protein or standard foods. After 6 weeks of dietary intervention, HP and RP groups additionally started a strength training intervention twice per week for 8 weeks. 24h dietary recalls were performed every 7 to 10 days. Body composition was assessed and blood taken. Plasma proteomics were assessed with LC-MS. Results: Participants of the HP group doubled their baseline protein intake from 0.80±0.31 g/kg BW/d to 1.63±0.36 g/kg BW/d; RP increased the protein intake from 0.89±0.28 g/kg BW/d to 1.06±0.26 g/kg BW/d. The CON group kept the protein intake stable throughout the study. Combined exercise and HP initiated notable changes, resulting in a reduction in bodyfat and increased muscle mass. Proteomics analyses revealed 14 significantly affected proteins by HP diet, regulating innate immune system, lipid transport and blood coagulation, yet the additional strength training did not elicit further changes. Conclusions: Combined HP and resistance exercise in healthy older adults seem to induce favorable changes in the body composition. Changes in the plasma proteome due to the high protein diet point to a beneficial impact for the innate immune system, lipid transport and blood coagulation system, all of which are involved in chronic disease development.
