MetabolomicsA metabolic dependency of EBV can be targeted to hinder B cell transformation

Following infection of B cells, Epstein Barr virus (EBV) engages host pathways that mediate cell proliferation and transformation, contributing to the propensity of the virus to drive immune dysregulation and lymphomagenesis. We found that the EBV protein EBNA2 initiates NAD de novo bios...

MetabolomicsMetabolomics reveals increased toxicity in earthworms (Eisenia fetida) of the transformation product methyl-triclosan
The effects of the antimicrobial triclosan (TCS) and its transformation product methyl-triclosan (MTCS) on the earthworm Eisenia fetida were investigated using GC-MS metabolomics. TCS is ubiquitous in sewage sludge, but a large proportion is transformed into MTCS during wastewater treatment and in s...

MetabolomicsA Combined LC-MS Metabolomics- and 16S rRNA Sequencing Platform to Assess Interactions between Herbal Medicinal Products and Human Gut Bacteria in Vitro: a Pilot Study on Willow Bark Extract
Herbal preparations are complex mixtures of natural products, many of which are able to reach the distal gut. There, they influence the microbial communities, and can be metabolized into bioactive metabolites. The aim of this study was to establish an interdisciplinary platform to unravel interactio...

TranscriptomicsIdentification of transformation-related pathways in a breast epithelial cell model using a ribonomics approach.
Employing MCT-1 oncogene mediated transformation of immortalized breast epithelial MCF10A cells; we characterized the largely reciprocal association of these two RBPs with target mRNAs and their influence on protein expression vis-à-vis cellular transformation. Using a ribonomics approach, we ident...

TranscriptomicsDual regulation of Fbw7 function and oncogenic transformation by Usp28
Fbw7, the substrate recognition subunit of SCF(Fbw7) ubiquitin ligase, mediates turnover of multiple proto-oncoproteins and promotes its own degradation. Fbw7-mediated substrate degradation is antagonized by the Usp28 deubiquitinase. We now show, using knockout mice, that Usp28 preferentially deubiq...

TranscriptomicsGenome-wide copy number analyses reveal genomic abnormalities involved in transformation of follicular lymphoma
We studied 277 lymphoma samples (198 FL and 79 transformed FL [tFL]) using a single-nucleotide polymorphism array to identify the secondary chromosomal abnormalities that drive the development of FL and its transformation to diffuse large B-cell lymphoma. Affymetrix 250K NspI SNP arrays were perform...

TranscriptomicsEMT inducers catalyze malignant transformation of mammary epithelial cells and drive tumorigenesis towards claudin-low tumors [mouse]
The newly identified claudin-low subtype of cancer is believed to represent the most primitive breast malignancies, having arisen from transformation of an early epithelial precursor with inherent stemness properties and metaplastic features. Challenging this hypothesis, we show both in vitro and in...

TranscriptomicsLipoic acid prevents Cr6+ induced cell transformation and the associated genomic dysregulation.
Investigation of the transcription profile of cells transformed by Cr6+ in vivo was undertaken. The objective was to elucidate genomic changes underlying the mechanism of action of the carcinogenic dose of Cr6+and their prevention using metabolic antioxidant Lipoic acid (LA). Cr6+ was administered i...

TranscriptomicsEpigenetic antagonism between Snf5 and Ezh2 during oncogenic transformation
Epigenetic alterations have been increasingly implicated in oncogenesis. Analysis of Drosophila mutants suggests that Polycomb and SWI/SNF complexes can serve antagonistic developmental roles. However, the relevance of this relationship to human disease is unclear. Here we have investigated function...
