RUNX1 and neoplasm: To further validate our initial findings and to evaluate the ETV6/RUNX1-positive BCP-ALL cell line REH, as a suitable in vitro model system to study the functional relevance of ETV6/RUNX1-specific lncRNAs, we analyzed publically available non-stranded poly-A RNA sequencing data from 13 human BCP-ALL tumor lines including REH and 12 other non-ETV6/RUNX1 cell lines (SEM, SUP-B15, NALM-6, NALM-19, RCH-ACV, RS4;11, KASUMI-2, KOPN-8, MUTZ-5, MHH-CALL-2, MHH-CALL-3 and MHH-CALL-4).
