TranscriptomicsComparative genomic hybridization of Clostridium sporogenes and Clostridium botulinum strains
Clostridium botulinum is a heterogeneous Gram-positive species that comprises four genetically and physiologically distinct groups of bacteria that share the ability to produce botulinum neurotoxin, the most poisonous toxin known to man, and the causative agent of botulism, a severe disease of human...

MetabolomicsCryogenic OrbiSIMS Localizes Semi-Volatile Molecules in Biological Tissues
OrbiSIMS is a recently developed instrument for label-free imaging of chemicals with micron spatial resolution and high mass resolution. We report a cryogenic workflow for OrbiSIMS (Cryo-OrbiSIMS) that improves chemical detection of lipids and other biomolecules in tissues. Cryo-OrbiSIMS boosts ioni...

TranscriptomicsMeiotic cohesin, chromatin and expression profiling of Arabidopsis thaliana floral buds from wild type and non-CG DNA methylation/H3K9me2 pathway mutant plants (ChIP-seq)
We generated and sequenced ChIP libraries for the meiotic cohesin subunit REC8 and four histone modifications (H3K4me1, H3K4me2, H3K9me2 and H3K27me1) to investigate their relationships with meiotic chromosome architecture and recombination in Arabidopsis thaliana. REC8 and H3K9me2 ChIP-seq were per...

TranscriptomicsGenomic consequences of background effects on scalloped mutant expressivity in the wing of Drosophila
Genetic background effects contribute to the phenotypic consequences of mutations, and are pervasive across all domains of life that have been examined, yet little is known about how they modify genetic systems. In part this is due to the lack of tractable model systems that have been explicitly de...

GenomicsChIP Seq of Oct4, Nanog, H3K27me3 in Oct4+/+ and Oct4 +/- mES cells
Embryonic stem cell (ESC) pluripotency is governed by a gene regulatory network centred on the transcription factors Oct4 and Nanog. ESCs fluctuate between states of high and low Nanog expression that direct efficient or inefficient self-renewal. To date, robust self-renewing ESC states have only be...

TranscriptomicsD. simulans vs. Sechellia adult bodies choice vs. no choice -DGRC Two Colour arrays with Dye Swapping
Here we show that Drosophila sechellia—a specialist on the fruit of Morinda citrifolia that recently diverged from its generalist sister-species, D. simulans—has rapidly accumulated loss-of-function alleles and reduced gene expression at genes affecting olfaction, detoxification, and metabolism....

TranscriptomicsGene expression profiling of mesenchyme-derived cell populations in the human airways
Mesenchyme-derived cells in the human airway wall including airway smooth muscle cells, fibroblasts and myofibroblasts are known to play important roles in airway remodeling. The lack of specific phenotypic markers makes it difficult to define these cell populations in primary cultures. The objectiv...
