Project description:Bat adenoviruses are a group of recently identified adenoviruses (AdVs) which are highly prevalent in bats yet share low similarity to known AdVs from other species. In this study, deep RNA sequencing was used to analyze the transcriptome at five time points following the infection of a bat AdV in a kidney cell line derived from a myotis bat species. Evidence of AdV replication was observed with the proportion of viral RNAs ranging from 0.01% at 6 h to 1.3% at 18 h. Further analysis of viral temporal gene expression revealed three replication stages; the early stage genes encoding mainly for host interaction proteins, the intermediate stage genes for the DNA replication and assembly proteins, and the late stage genes for most structural proteins. Several bat AdV genes were expressed at stages that differed from their counterpart genes previously reported for human AdV. In addition, single-base resolution splice sites of several genes and promoter regions of all 30 viral genes were fully determined. Simultaneously, the temporal cellular gene expression profiles were identified. The most overrepresented functional categories of the differentially expressed genes were related to cellular immune response, transcription, translation, and DNA replication and repair. Taken together, the deep RNA sequencing provided a global, transcriptional profile of the novel BtAdV and the virus-host interactions, which will be useful for the understanding and investigation of AdV replication, pathogenesis and specific virus-bat interactions in future research. Deep RNA sequencing was used to analyze the transcriptome at five time points(0h,6h,8h, 12h 18h) following the infection of a bat AdV in a bat kidney cell.

Project description:The bat offers an alternative paradigm to the standard mouse and chick model of limb development as it has extremely divergent forelimbs (long digits supporting a wing) and hindlimbs (short digits and claws) due the distinct requirements of both aerial and terrestrial locomotion. We used a cross-species microarray approach to identify differentially expressed (DE) genes between the bat (Minniopterus natalensis) forelimb and hindlimb autopods at Carollia developmental stages (CS) 16 and CS17, and between the bat (CS17) and mouse (E13.5) forelimb autopods. Several DE genes were identified, including two homeobox genes, Meis2, a proximal limb-patterning gene, and Hoxd11, a gene involved in digit elongation. Both genes are significantly over-expressed in the developing bat forelimb as compared to the hindlimb and equivalently staged mouse forelimbs. A reference design was used in this microarray experiment. A pool of left and right mouse forelimb autopods from 24 embryos was used as the reference sample. This sample was directly compared to individual CS16 and CS17 bat fore- and hindlimbs (left and right of one individual pooled) that were classified as the test conditions. Four experimental sessions were performed using an independently amplified mouse reference pool and 4 biological repeats for the bat limbs. These samples were co-hybridised to OPERON Mouse OpArray (ver. 4.0) spotted oligonucleotide slides to perform a competitive Cross-Species Hybridisation experiment. The bat aRNA (test) samples were labelled with Cy3 dye (green signal), the mouse aRNA (reference) sample was labelled with Cy5 dye (red signal).

Project description:We performed a genome-wide deep sequencing analysis of the microRNAs abundant in mesenchymal stem cells (MSCs) derived from murine brown adipose tissue and in in vitro differentiated mature brown adipocytes. Several microRNAs were identified as differentially regulated when comparing datasets from MSCs vs. mature fat cells. These microRNAs may have an implication in the regulation of adipogenesis as well as thermogenesis in brown adipose tissue (BAT).

Project description:Variation among individuals is a prerequisite of evolution by natural selection. As such, identifying the origins of variation is a fundamental goal of biology. We investigated the link between gene interactions and variation in gene expression among individuals and species, using the mammalian limb as a model system. We first built interaction networks for key genes regulating early (outgrowth; E9.5-11) and late (expansion and elongation; E11-13) limb development in mouse. This resulted in an Early (ESN) and Late (LSN) Stage Network. Computational perturbations of these networks suggest that the ESN is more robust. We then quantified levels of the same key genes among mouse individuals, and found that they vary less at earlier limb stages and that variation in gene expression is heritable. Finally, we quantified variation in gene expression levels among four mammals with divergent limbs (bat, opossum, mouse and pig), and found that levels vary less among species at earlier limb stages. We also found that variation in gene expression levels among individuals and species are correlated for earlier and later limb development. In conclusion, results are consistent with the robustness of the ESN buffering among-individual variation in gene expression levels early in mammalian limb development, and constraining the evolution of early limb development among mammalian species. Bat, mouse, opossum, and pig mRNA profiles at early and late developmental stages on each species fore and hind-limbs . Various replicates of each library were generated by single-end sequencing using Illumina HiSeq 2500. Please note that the De novo transcriptome assembly for bat (Trinity.fasta) was generated from pooled RNA-seq data of fore and hind-limbs at various embryonic developmental stages; Beginning stage (Wanek stage 2: 3 FL and 3 HL samples), early-stage (Wanek stage 3/4: 2 FL and 2 HL samples), and late_stage (Wanke stage 6: 2 FL and 2 HL samples).

Project description:Brown adipose tissue (BAT) burns fatty acids to produce heat, and shows diurnal oscillation with peak activity in glucose and triglyceride-derived fatty acid uptake at wakening. To gain further insight in the diurnal regulation of metabolic BAT activity, we performed chromatin immunoprecipitation sequencing (ChIP-seq) on pooled interscapular (i)BAT samples collected from chow-fed male C57BL/6J mice (10 weeks old) exposed to mild cold (22°C) at 3-hour intervals throughout a 24-hour period (n=8 mice per time point). All mice were entrained to a 12h:12h light:dark cycle, and therefore time is denoted as Zeitgeber Time (ZT) in which ZT0 indicates the onset of the light (active) phase.
