Significance To date, various studies have found similarities between humans and mice on a molecular level, indeed, the murine model serves as an important experimental system for biomedical science. In this study of broad number tissues mice, high-throughput sequencing assays transcriptome epigenome reveal that, in general, differences dominate two species. These findings provide basis understanding phenotypes responses to conditions mice.

Post-mortem tissues samples are a key resource for investigating patterns of gene expression. However, the processes triggered by death and post-mortem interval (PMI) can significantly alter physiologically normal RNA levels. We investigate impact PMI on expression using data from multiple donors obtained GTEx project. find that many genes change over relatively short PMIs in tissue-specific manner, but this potentially confounding effect biological analysis be minimized taking into account...

We present ggsashimi, a command-line tool for the visualization of splicing events across multiple samples. Given specified genomic region, ggsashimi creates sashimi plots individual RNA-seq experiments as well aggregated groups experiments, feature unique to this software. Compared existing versions programs generating plots, it uses popular bioinformatics file formats, is annotation-independent, and allows even large regions by scaling down segments between splice sites. freely available...

A comparison of transcriptional profiles derived from different tissues in a given species or among assumes that commonalities reflect evolutionarily conserved programs and differences tissue responses to environmental conditions developmental program staging. Apparently conflicting results have been published regarding whether organ-specific patterns dominate over species-specific patterns, vice versa, making it unclear what extent the biology organism can be extrapolated another. These...

Mice have been a long-standing model for human biology and disease. Here we characterize, by RNA sequencing, the transcriptional profiles of large heterogeneous collection mouse tissues, augmenting transcriptome with thousands novel transcript candidates. Comparison in cell lines reveals substantial conservation programmes, uncovers distinct class genes levels expression that constrained early vertebrate evolution. This core set captures fraction output mammalian cells, participates basic...

We have produced RNA sequencing data for 53 primary cells from different locations in the human body. The clustering of these reveals that most body share a few broad transcriptional programs, which define five major cell types: epithelial, endothelial, mesenchymal, neural, and blood cells. These act as basic components many tissues organs. Based on gene expression, types redefine histological by been traditionally classified. identified genes whose expression is specific to types, genes, we...

Natural Antisense Transcripts (NATs) are long non-coding RNAs (lncRNAs) that overlap coding genes in the opposite strand. NATs roles have been related to gene regulation through different mechanisms, including post-transcriptional RNA processing. With aim identify with potential regulatory function during fly development, we generated RNA-Seq data Drosophila developing tissues and found bsAS , one of most highly expressed lncRNAs wing. is antisense bs/DSRF a involved wing development neural...

Abstract Background During development, most cells undergo striking changes in order to develop into functional tissues. All along this process, the identity of each tissue arises from particular combination regulatory transcription factors that specifically control expression relevant genes for growth, pattern formation and differentiation. In scenario, regulation gene turns out be essential determine cell fate specificity. Results To characterize dynamic transcriptional profiles during...

The formation of chimeric transcripts (chimeras) has been widely reported [1,2,3]. Some them reflect underlying chromosomal rearrangements [4] or are the results propensity reverse transcriptase to engage in template switching [5]. However, a proportion cases genuinely appear correspond trans-splicing RNAs, as previously described [6,7]. Here, we use ENCODE and mouse deeply sequenced bio-replicated RNaseq data from 18 human 30 samples, ChimPipe program identify chimeras occurring multiple...
