MetabolomicsGenome-wide mapping of genetic suppression events in Streptococcus pneumoniae
Historically, suppressor analysis has been a powerful tool for uncovering the functions of essential genes. In this study, we report Sup-seq, a transposon-sequencing technique with random DNA barcodes that enables genome-wide detection of genetic suppression. When applied to seven essential genes in...

MetabolomicsIlluminating the dark space of neutral glycosphingolipidome by selective enrichment and profiling at multi-structural levels

Glycosphingolipids (GSLs) are essential components of cell membranes, particularly enriched in the nervous system. Altered molecular distributions of GSLs are increasingly associated with human diseases, emphasizing the significance of lipidomic profiling. Traditional GSL analysis methods are ham...

GenomicsLong Span DNA Paired-End-Tag (DNA-PET) Sequencing Strategy for the Interrogation of Genomic Structural Mutations
Structural variations (SVs) contribute significantly to the variability of the human genome and extensive genomic rearrangements are a hallmark of cancer. Genomic DNA paired-end-tag (DNA-PET) sequencing is an attractive approach to identify genomic SVs. The current application of PET sequencing with...

GenomicsComprehensive Long Span Paired-End-Tag Mapping Reveals Characteristic Patterns of Structural Variations in Epithelial Cancer Genomes
Somatic genome rearrangements are thought to play important roles in cancer development. We optimized a long span paired-end-tag (PET) sequencing approach using 10 Kb genomic DNA inserts to study human genome structural variations (SVs). The use of 10 Kb insert size allows the identification of brea...

MetabolomicsMapping the metabolism of five amino acids in bloodstream form Trypanosoma brucei using U-13C-labelled substrates and LC–MS
The metabolism of the parasite Trypanosoma brucei has been the focus of numerous studies since the 1940s. Recently it was shown, using metabolomics coupled with heavy-atom isotope labelled glucose, that the metabolism of the bloodstream form parasite is more complex than previously thought. The pres...

TranscriptomicsMapping DNA structural variation in dogs
DNA structural variation (SV) comprises a major portion of genetic diversity, but its biological impact is unclear. We propose that the genetic history and extraordinary phenotypic variation of dogs make them an ideal mammal in which to study the effects of SV on biology and disease. The hundreds of...

TranscriptomicsFine-Scale Mapping and Sequencing of Structural Variation from Eight Human Genomes
Genetic variation amongst individual humans occurs on many different scales, ranging from gross alterations in the human karyotype to single-nucleotide changes. In this manuscript we explore variation on an intermediate scale-particularly insertions, deletions, and inversions affecting from a few t...

TranscriptomicsValidation of genomic structural variation predictions in fruit flies
Whole-genome tiling arrays were used to validate deletions and tandem duplications that were inferred based on next-generation sequencing data. The arrays were generated for six samples of the Drosophila melanogaster Genetic Reference Panel (DGRP) as well as the Berkeley reference strain. Structural...

Transcriptomics8-chip high-resolution aCGH experiment NA15510 vs. NA18505
We introduce high-throughput and massive paired-end mapping (PEM), a large-scale genome sequencing method to identify SVs 3 kb or larger that combines the rescue and capture of paired-ends of 3 kb fragments, massive 454 Sequencing, and a computational approach to map DNA reads onto a reference genom...
