MetabolomicsUltra-High Mass Resolving Power, Mass Accuracy, and Dynamic Range MALDI Mass Spectrometry Imaging by 21-T FT-ICR MS

Detailed characterization of complex biological surfaces by matrix-assisted laser desorption/ionization (MALDI) mass spectrometry imaging (MSI) requires instrumentation that is capable of high mass resolving power, mass accuracy and dynamic range. Fourier transform ion cyclotron resonance mass sp...

TranscriptomicsGene expression profiling of two DLBCL cell lines upon shRNA mediated knockdown of EZH2
We studied transcriptional changes by Affymetrix human microarrays in 2 DLBCL cell lines as a result of shRNA mediated knockdown of EZH2. In eukaryotes, epigenetic post-translational modification of histones is critical for regulation of chromatin structure and gene expression. EZH2 is the catalytic...

MetabolomicsUntargeted Metabolomics for Integrative Taxonomy: Metabolomics, DNA Marker-Based Sequencing, and Phenotype Bioimaging

Integrative taxonomy is a fundamental part of biodiversity and combines traditional morphology with additional methods such as DNA sequencing or biochemistry. Here, we aim to establish untargeted metabolomics for use in chemotaxonomy. We used three thallose liverwort species Riccia glauca

TranscriptomicsGene expression profiling of EZH2 mutant and wild type DLBCL cell lines treated with EZH2 inhibitor
We studied transcriptional changes by Affymetrix human microarrays in DLBCL cell lines as a result of treatment with GSK126, a potent, highly-selective, SAM-competitive, small molecule inhibitor of EZH2 In eukaryotes, epigenetic post-translational modification of histones is critical for regulation ...

GenomicsChIP-seq analysis of H3K27me3 histone modification in EZH2 mutant and wild type DLBCL cell lines
In eukaryotes, epigenetic post-translational modification of histones is critical for regulation of chromatin structure and gene expression. EZH2 is the catalytic subunit of the Polycomb Repressive Complex 2 (PRC2) and is responsible for repressing target gene expression through methylation of histo...

MetabolomicsDual transcriptomic & metabolomic analysis of elicited flax sheds light on the kinetics of immune defense activation against the biotrophic pathogen Oidium lini.
Flax (Linum usitatissimum) grown under controlled conditions displayed genotype-dependent resistance to powdery mildew (Oidium lini) following COS-OGA (comprising chitosan- and pectin-derived oligomers) elicitor application. The present study reveals a two-step immune response in plant...

MetabolomicsRelease of Ecologically Relevant Metabolites by the Cyanobacterium, Synechococcus elongatus CCMP 1631
Phytoplankton are known to release organic compounds that fuel secondary production by heterotrophic bacteria. Here we show that an abundant marine cyanobacterium, Synechococcus elongatus, contributes a variety of nitrogen-rich and sulfur-containing compounds to dissolved organic matter. A combinati...

MetabolomicsSponge exhalent seawater contains a unique chemical profile of dissolved organic matter
Sponges are efficient filter feeders, removing significant portions of particulate and dissolved organic matter (POM, DOM) from the water column. While the assimilation and respiration of POM and DOM by sponges and their abundant microbial symbiont communities have received much attention, there is ...

TranscriptomicsInhibition of BET bromodomain proteins as a therapeutic approach in prostate cancer
We analyzed transcriptional changes in 4 prostate cancer cell lines following treatment with the BET inhibitor I-BET762 using Affymetrix Human Genome U133 Plus 2.0 Arrays. Four prostate cancer cell lines (NCI-H660, VCaP, LNCaP, PC-3) were treated with DMSO (control) or I-BET762 at 0.5uM or 10uM con...
