Targeting transcription regulation in cancer with a covalent CDK7 inhibitor.
Boston, United States. In Nature, Aug 2014
Genome-wide analysis in Jurkat T-ALL cells shows that THZ1 disproportionally affects transcription of RUNX1 and suggests that sensitivity to THZ1 may be due to vulnerability conferred by the RUNX1 super-enhancer and the key role of RUNX1 in the core transcriptional regulatory circuitry of these tumour cells.
Reprogramming human endothelial cells to haematopoietic cells requires vascular induction.
New York City, United States. In Nature, Aug 2014
Highly purified non-haemogenic human umbilical vein endothelial cells or adult dermal microvascular endothelial cells were transduced with the transcription factors FOSB, GFI1, RUNX1 and SPI1 (hereafter referred to as FGRS), and then propagated on serum-free instructive vascular niche monolayers to induce outgrowth of haematopoietic colonies containing cells with functional and immunophenotypic features of multipotent progenitor cells (MPPs).
Role of genotype-based approach in the clinical management of adult acute myeloid leukemia with normal cytogenetics.
Boston, United States. In Leuk Res, Jun 2014
However, a widespread genomic analysis has recently shown the recurrence of genomic aberrations in this category (mutations of FLT3, CEBPA, NPM1, RUNX1, TET2, IDH1/2, DNMT3A, ASXL1, MLL and WT1) thus revealing its marked genomic heterogeneity.
A RAG driver on the road to pediatric ALL.
Nijmegen, Netherlands. In Nat Genet, Feb 2014
A new whole-genome sequencing study of ETV6-RUNX1-positive ALL has now identified RAG-mediated recombination, which specifically targets genes and regulatory elements active during B cell differentiation, as the underlying mechanism.
Somatic mutations and epigenetic abnormalities in myelodysplastic syndromes.
Paris, France. In Best Pract Res Clin Haematol, Dec 2013
Recently, the advent of next generation sequencing (NGS) techniques has helped identify somatic gene mutations in 75-80% of MDS, that cluster mainly in four functional groups, i.e. cytokine signaling (RAS genes), DNA methylation, (TET2, IDH1/2, DNMT3a genes) histone modifications (ASXL1 and EZH2 genes), and spliceosome (SF3B1 and SRSF2 genes) along with mutations of RUNX1 and TP 53 genes.
Systems biology of megakaryocytes.
Seattle, United States. In Adv Exp Med Biol, Dec 2013
Several transcription factors critical for generating megakaryocytes were identified by promoter analysis of megakaryocyte-specific genes, and their biological roles then verified by gene knockout studies; for example, GATA-1, NF-E2, and RUNX1 were identified in this way.
