Project description:Obesity and associated increased prevalence of non-alcoholic fatty liver (NAFLD) disease is suggested to be positively modulated by a high protein (HP) diet in humans and rodents. The aim was to detect mechanisms by which a HP diet prevents hepatic lipid accumulation by means of transcriptomics. To study the acute and long term effect of a high protein ingestion on hepatic lipid accumulation under both low and high fat (HF) conditions, mice were fed combinations of high (35%) or low (10%) fat and high (50%) or normal (15%) protein diets for 1 or 12 weeks. Body composition, liver fat, VLDL production rate and gene expression were investigated. Differences in metabolic processes and functions in the liver were identified using gene set enrichment analysis on microarray data. Mice fed the HP diets developed less adiposity and decreased hepatic lipid accumulation due a combination of induced processes mainly involved in protein catabolism such as transamination, TCA cycle and oxidative phosphorylation. Feeding a HP diet can successfully prevent the development of NAFLD by using ingested energy for oxidation instead of storage. Wild type mice were fed combinations of high (35%) or low (10%) fat and high (50%) or normal (15%) protein diets for 1 or 12 weeks. After the diet intervention period, the animals were killed and liver tissue was removed. Total RNA was isolated, pooled and subjected to gene expression profiling.

Project description:We identified genes regulated by parasitization of the silkworm Bombyx mori by three tachinid parasitoid species, Exorista japonica, Drino inconspicuoides and Pales pavida, using oligonucleotide microarrays. The numbers of genes and their intensity of expression varied with the species of parasitoid, within silkworm hemocytes and fat body. Bombyx mori hemocyte, silkgland and fat body samples parasitizated by Exorista japonica, Drino inconspicuoides and Pales pavida were prepared. Gene expression was compared in these two groups: control and parasitized.

Project description:MicroRNAs are a class of molecular regulators found to participate in numerous biological processes, including adipogenesis. However, whether dietary changes impact on microRNA (miRNA) in ruminants has not been reported. Therefore, this study aimed to evaluate the dietary effect on miRNA expression in subcutaneous (backfat) and visceral fat depots (perirenal fat) from beef steers fed with different diets containing high or low fat levels. Fat tissues were collected from 16 Hereford x Aberdeen Angus cross bred steers (15.5 month old) fed high fat diet (5.85% fat, n=8) or control diet (1.95% fat, n=8). Total RNA from each animal was subjected to miRNA microarray analysis using a customized Agilent miRNA microarray containing 672 bovine miRNA probes. Expression of miRNAs was not equally detected under two diets; 169 miRNAs were commonly expressed while 75 were diet specific. The number of miRNAs detected per animal under high fat diet was higher than those fed control diet (p= 0.037 in subcutaneous fat and p= 0.002 in visceral fat).. Further qRT-PCR analysis confirmed that the expression of some miRNAs was highly influenced by diet (miR-19a, -92a, -92b, -101, -103, -106, -142-5p, and 296) or fat depot (miR-196a and -2454). Our results revealed that the miRNA expression can be influenced by types of fat tissues or diet, suggesting that miRNAs may regulate bovine adipogenesis when diet alters.
