MetabolomicsMetabolome variability for two Mediterranean sponge species of the genus Haliclona: specificity, time, and space

INTRODUCTION: The study of natural variation of metabolites brings valuable information on the physiological state of the organisms as well as their phenotypic traits. In marine organisms, metabolome variability has mostly been addressed through targeted studies on metabolites of...

MetabolomicsA metabolomic study of adipose tissue in mice with a disruption of the circadian system

Adipose tissue functions in terms of energy homeostasis as a rheostat for blood triglyceride, regulating its concentration, in response to external stimuli. In addition it acts as a barometer to inform the central nervous system of energy levels which can vary dramatically between meals and accor...

MetabolomicsPhospholipid acyl chain diversity controls the tissue-specific assembly of mitochondrial cardiolipins

Cardiolipin (CL) is a phospholipid specific for mitochondrial membranes and crucial for many core tasks of this organelle. Its side chain configurations are tissue-specific, functionally important and generated via post-biosynthetic remodeling. However, this process lacks the necessary specificit...

MetabolomicsMetabolomics Analysis Reveals Tissue-Specific Metabolite Compositions in Leaf Blade and Traps of Carnivorous Nepenthes Plants
Nepenthes is a genus of carnivorous plants that evolved a pitfall trap, the pitcher, to catch and digest insect prey to obtain additional nutrients. Each pitcher is part of the whole leaf, together with a leaf blade. These two completely different parts of the same organ were studied separately in a...

TranscriptomicsResponsiveness of genes to manipulation of transcription factors in ES cells is associated with chromatin structure and tissue specificity
Background: In addition to determining static states of gene expression (high vs. low), it is important to characterize their dynamic status. For example, genes with H3K27me3 chromatin marks are not only suppressed but also poised for activation. However, the responsiveness of genes to perturbations...

TranscriptomicsIdentification of Tissue-Specific Protein-Coding and Noncoding Transcripts across 14 Human Tissues Using RNA-seq
Many diseases and adverse drug reactions exhibit tissue specificity. To better understand the tissue-specific expression characteristics of transcripts in different human tissues, we deeply sequenced RNA samples from 14 different human tissues. After filtering many lowly expressed transcripts, 24,72...

TranscriptomicsRNA-seq reveals that Air1 and Air2 control TRAMP substrate specificity for nuclear RNA surveillance
The Saccharomyces cerevisiae TRAMP4 and TRAMP5 complexes, which consist of the poly(A) polymerase Trf4 or Trf5, respectively, the zinc knuckle proteins Air1 or Air2, and the RNA helicase Mtr4, play a critical role in nuclear RNA surveillance. Although it is known to enhance the nuclease activity of ...

TranscriptomicsAn RNASeq normal tissue atlas for mouse and rat
The function of a gene is closely connected to its expression specificity across tissues and cell types. RNA-Seq is a powerful quantitative tool to explore genome wide expression. The aim of the present study is to provide a comprehensive RNA-Seq dataset across the same 13 tissues for mouse and rat,...
