Project description:To explore the effects of the housing condition (group- or single-housing) on killifish, we performed RNA-seq analysis for the whole bodies of male and female juveniles, gonads of males and females from puberty to middle age, and livers of young and old males.

Project description:Purpose: To identify the impact of thermoneutral housing as opposed to standard housing on gene expression profiles in the mouse peripheral blood mononuclear cells (PBMCs), focusing on proinflammatory immune responses and high-fat diet induced non-alcoholic fatty liver disease pathogenesis. Methods: Expression profiles from PBMCs collected from C57Bl6 mice fed chow or high-fat diet for 8 weeks, following 2 weeks at either standard or thermoneutral housing conditions. Sequencing was performed in duplicate, the Illumina HiSeq 2500. Transcripts that passed quality filters were analyzed at the gene level, using Strand NGS for accurate alignment and quantification. Results: We mapped approximately 20million reads per sample to the mm10 genome using annotations produced by Ensembl, which represented 36186 transcripts. Approximately 14000 genes exhibited reasonable expression in at least one experimental condition. The primary focus was the effect of housing temperature while holding diet consistent (i.e. thermoneutral vs standard, both on high-rat diet), where ~2700 genes exhibited differential regulation. Conclusions: We present the transcriptomic profile of PBMCs from mice fed chow of high-fat diets, following either standard or thermoneutral housing. We obseve an augmented proinflammatory immune response.

Project description:Comparative analysis of gene expression profiles in newly developed housing systems is important to understand gene functions in chicken for adaptation and possible gene-environment interactions among layer lines. Therefore, the objective of this study was to characterize the molecular processes that are different among the two layer lines Lohmann Selected Leghorn (LSL) and Lohmann Brown (LB) using whole genome RNA expression profiles. Despite their approximately identical egg production performance these layer lines differ markedly in other phenotypic traits. The two layer lines were kept under the production environment of the newly developed small group housing system Eurovent German with two different group sizes and three tiers. We used a chicken RNA microarray to identify differentially expressed genes among the two layer lines LSL and LB.

Project description:Background: Weaning of beef calves is a necessary husbandry practice and involves separating the calf from its mother, resulting in numerous stressful events including dietary change, social reorganisation and the cessation of the maternal-offspring bond and is often accompanied by housing. While much recent research has focused on the physiological response of the bovine immune system to stress in recent years, little is known about the molecular mechanisms modulating the immune response. Therefore, the objective of this study was to provide new insights into the molecular mechanisms underlying the physiological response to weaning at housing in beef calves using Illumina RNA-seq. Results: The leukocyte transcriptome was significantly altered for at least 7 days following either housing or weaning at housing. Analysis of differentially expressed genes revealed that four main pathways, cytokine signalling, transmembrane transport, haemostasis and G-protein-coupled receptor (GPRC) signalling, were differentially regulated between control and weaned calves and underwent significant transcriptomic alterations in response to weaning stress on day 1, 2 and 7. Of particular note, chemokines, cytokines and integrins were consistently found to be up-regulated on each day following weaning. Evidence for alternative splicing of genes was also detected, indicating that a number of genes involved in the innate and adaptive immune response may be alternatively transcribed, including those responsible for toll receptor cascades and T cell receptor signalling. Conclusions: This study represents the first application of RNA-Seq technology for genomic studies in bovine leukocytes in response to weaning stress. Weaning stress induces the activation of a number of cytokine, chemokine and integrin transcripts and may alter the immune system whereby the ability of a number of cells of the innate and adaptive immune system to locate and destroy pathogens is transcriptionally enhanced. Stress alters the homeostasis of the transcriptomic environment of leukocytes for at least 7 days following weaning, indicating long-term effects of stress exposure in the bovine. The identification of gene signature networks that are stress activated provides a mechanistic framework to characterise the multifaceted nature of weaning stress adaptation in beef calves. Thus, capturing subtle transcriptomic changes provides insight into the molecular mechanisms that underlie the physiological response to weaning stress. Examination of a time course (day 0, 1, 2 and 7) for 2 treatments, calves either housed with their dam (control) or housed and simultaneously weaned, using RNA-seq. The supplementary processed data file 'read_counts.txt' contains unnormalized read counts for each Ensembl bovine gene in each of the 48 samples. Unnormalized counts are required for input to EdgeR.
