The acute avian leukaemia retroviruses AMV and E26 both induce myeloblastosis in vivo and transform myeloblasts in vitro. Both viruses contain the oncogene v-myb first described for AMV. Unlike AMV, E26 has the additional capacity to induce erythroblastosis in vivo and to transform erythroblasts. Previous analyses indicated that the genome of E26 also(More)
E26 is an acute leukaemia avian retrovirus which induces myeloblastosis and erythroblastosis in vivo and transforms erythroblasts and myeloblasts in vitro. It contains the oncogene v-myb (ref. 4), first described for avian myeloblastosis virus (AMV), as well as a second specific nucleotide sequence, v-ets located 3' to v-myb (refs 5,6). We have reported(More)
Bromodomain protein 4 (BRD4) is a chromatin-binding protein implicated in cancer and autoimmune diseases that functions as a scaffold for transcription factors at promoters and super-enhancers. Although chromatin decompaction and transcriptional activation of target genes are associated with BRD4 binding, the mechanisms involved are unknown. We report that(More)
In order to investigate a possible function of ETS proto-oncogenes in human brain, we incubated a polyclonal antibody raised against the viral region of E26 homologous to ETS1 and ETS2 with human brain frontal cortex sections. Our results show that this antibody decorates astrocytes but not neurons. By using astrocytomas of different grades as a source of(More)
