Aging of preleukemic thymocytes drives CpG island hypermethylation in T-cell acute lymphoblastic leukemia

Cancer cells display DNA hypermethylation at specific CpG islands in comparison to their normal healthy counterparts, but the mechanism that drives this so-called CpG island methylator phenotype (CIMP) remains poorly understood. Here, we show that CpG island methylation in human T-cell acute lymphoblastic leukemia (T-ALL) mainly occurs at promoters of Polycomb Repressor Complex 2 (PRC2) target genes that are not expressed in normal or malignant T-cells and which display a reciprocal association with H3K27me3 binding.

Novel non-TCR chromosome translocations t(3;11)(q25;p13) and t(X;11)(q25;p13) activating LMO2

In T-cell acute lymphoblastic leukemia (T-ALL) cytogenetic alterations juxtapose the LIM-domain-only-2 gene (LMO2) with T-cell receptor loci.

Receptor mutation is not a common mechanism of naturally occurring glucocorticoid resistance in leukaemia cell lines

Glucocorticoids (GCs) are among the most important drugs for the treatment of acute lymphoblastic leukaemia (ALL).

Novel BRD4-NUT fusion isoforms increase the pathogenic complexity in NUT midline carcinoma

This study contributes to our understanding of the genetic diversity of NMC, an important step towards finding therapeutic targets for a disease that is...

Fusionfinder: A software tool to identify expressed gene fusion candidates from RNA-seq data

The hallmarks of many haematological malignancies and solid tumours are chromosomal translocations, which may lead to gene fusions.

Dose-dependent hepatotoxicity of hydrogen peroxide in HepG2 cells and its modulation by CYP450 induction

In vitro liver models combined with metabolomics approaches offer promising alternatives to animal testing in toxicology. In this study, we investigated concentration-dependent effects of hydrogen peroxide on the intra- and extracellular metabolome of HepG2 cells using 1H Nuclear Magnetic Resonance spectroscopy.
