MetabolomicsComprehensive evaluation of untargeted metabolomics data processing software in feature detection, quantification and discriminating marker selection
Data analysis represents a key challenge for untargeted metabolomics studies and it commonly requires extensive processing of more than thousands of metabolite peaks included in raw high-resolution MS data. Although a number of software packages have been developed to facilitate untargeted data proc...

MetabolomicsSelection strengthens the relationship between plant diversity and the metabolic profiles of Plantago lanceolata

• Plant species diversity enhances community productivity, but how plant diversity impacts the metabolome of individual plants and the underlying eco-evolutionary processes remains unclear. This study investigated how plant species diversity and selection for growing in different diversity enviro...

MetabolomicsA Divergent Selection on Breast Meat Ultimate pH, a Key Factor for Chicken Meat Quality, is Associated With Different Circulating Lipid Profiles

BACKGROUND: Chicken meat has become a major source of protein for human consumption. However, the quality of the meat is not yet under control, especially since pH values that are too low or too high are often observed. In an attempt to get a better understanding of the genetic a...

TranscriptomicsAnalysis of severe feather pecking behavior in a high feather pecking selection line
Even though feather pecking (FP) in laying hens has been extensively studied, a good solution to prevent chickens from this behavior under commercial circumstances has not been found. Selection against FP behavior is possible, but for a more effective selection across different populations, it is ne...

TranscriptomicsThe transcriptional consequences of mutation and natural selection in Caenorhabditis elegans
This set of arrays contains all microarray experiments done involving comparisons among C. elegans natural isolates and mutation-accumulation lines. Abstract: The evolutionary importance of gene-expression divergence is unclear: some studies suggest that it is an important mechanism for evolution by...

TranscriptomicsNatural selection on cis and trans regulation in yeasts
Gene expression is regulated both by cis elements, which are DNA segments closely linked to the genes they regulate, and by trans activating factors, which are usually proteins capable of diffusing to unlinked genes. Understanding the patterns and sources of regulatory variation is crucial for under...

TranscriptomicssiRNA profiling of HeLa cells reveals strand-specific 5-O-methylation of siRNA duplexes controls guide strand selection and targeting specificity.
Small interfering RNAs (siRNAs) and microRNAs (miRNAs) guide catalytic sequence-specific cleavage of fully or nearly fully complementary target mRNAs or control translation and/or stability of many mRNAs that share 6-8 nucleotides (nt) of complementarity to the siRNA and miRNA 5' end. siRNA- and miR...

TranscriptomicsThe role of Ternary Complex factors in T-cell Positive Selection
Removal of the transcription factor SAP1a member of the Ternary Complex Factor (TCF) group of transcription factors which in conjunction with Serum Response Factor (SRF) has been shown to have a profound effect on positive selection in the thymus. When another TCF Elk1 is knocked out in mice there i...
