ETV6/RUNX1 (E/R) is the most common fusion gene in childhood acute lymphoblastic leukemia. It is responsible for the initiation of leukemia but also indispensable for disease maintenance and propagation, although its function in these latter processes is less clear. We therefore investigated the effects of the perceived p53 pathway alterations in model cell(More)
BACKGROUND Though p53 mutations are rare in ES, there is a strong indication that p53 mutant tumours form a particularly bad prognostic group. As such, novel treatment strategies are warranted that would specifically target and eradicate tumour cells containing mutant p53 in this subset of ES patients. METHODS PRIMA-1(Met), also known as APR-246, is a(More)
The Ewing sarcoma (ES) EWS-FLI1 chimeric oncoprotein is a prototypic aberrant ETS transcription factor with activating and repressive regulatory functions. We report that EWS-FLI1-repressed promoters are enriched in forkhead box (FOX) recognition motifs, and identify FOXO1 as a EWS-FLI1-suppressed regulator orchestrating a major subset of EWS-FLI1-repressed(More)
Plasmid DNA harbouring the human 5S rRNA gene was assembled into nucleosomes using either Xenopus S150 extracts or purified core histones in the presence of pectin. In both cases reconstitution of nucleosomes led to a complete repression of transcription. This repression could be efficiently counteracted by preincubating the template DNA with highly(More)
