MetabolomicsA statistical analysis of the effects of urease pre-treatment on the measurement of the urinary metabolome by gas chromatography–mass spectrometry
Urease pre-treatment of urine has been utilized since the early 1960s to remove high levels of urea from samples prior to further processing and analysis by gas chromatography–mass spectrometry (GC–MS). Aside from the obvious depletion or elimination of urea, the effect, if any, of urease pre-treatm...

TranscriptomicsA receptor tyrosine kinase network comprised of FGFRs, EGFR, ERBB2, and MET drives growth and survival of HNSCC cell lines.
We have previously shown that some gefitinib insensitive head and neck squamous cell carcinoma (HNSCC) cell lines exhibit dominant autocrine fibroblast growth factor receptor (FGFR) signaling. Herein, we deployed a whole genome loss-of-function screen to identify genes whose knockdown potentiated th...

TranscriptomicsSomatic copy number variation profiling in matched brain and extracranial metastases of melanoma
An improved understanding of the molecular pathogenesis of brain metastases, one of the most common and devastating complications of advanced melanoma, may identify and prioritize rational therapeutic approaches for this disease. In particular, the identification of molecular differences between bra...

TranscriptomicsDifferential Gene Expression in Daphnia magna Suggests Distinct Modes of Action and Bioavailability for ZnO nanoparticles and Zn ions
Zinc Oxide nanoparticles (ZnO NPs) are being rapidly developed for use in consumer products, wastewater treatment and chemotherapy providing several possible routes for ZnO NP exposure to humans and aquatic organisms. Recent studies have shown that ZnO NPs undergo rapid dissolution to Zn+2, but the...

TranscriptomicsGene expression profiling of invasive breast cancer events from the tamoxifen prevention trial
Gene expression profiling of invasive breast cancer events from the tamoxifen prevention trial validates low estrogen receptor mRNA level as the main determinant of tamoxifen resistance in estrogen receptor positive breast cancer. In NSABP Breast Cancer Prevention Trial (BCPT), tamoxifen reduced th...

TranscriptomicsGuselkumab (interleukin-23-specific monoclonal antibody) demonstrates clinical and molecular response in moderate-to-severe psoriasis
A gene expression profiling study was conducted in which skin biopsy samples were collected for RNA extraction and hybridization to microarrays from patients with moderate-to-severe psoriasis who participated in the phase 1, guselkumab first-in-human randomized, double-blind, placebo-controlled tria...

TranscriptomicsHigh resolution temporal profiling of gene expression during Arabidopsis leaf development (senescence process)
Leaf senescence is an essential developmental process that involves altered regulation of thousands of genes and changes in many metabolic and signaling pathways resulting in massive physiological and structural changes in the leaf. The regulation of senescence is complex and although several senesc...

TranscriptomicsArabidopsis defense against Botrytis cinerea: chronology and regulation deciphered by high-resolution temporal transcriptomic analysis (tga3-2 knockout data)
Transcriptional reprogramming forms a major part of a plant's response to pathogen infection. Many individual components and pathways operating during plant defense have been identified but our knowledge of how these different components interact is still rudimentary. We have generated a high-resolu...
