KDM6B and Ewing sarcoma: Indeed, analysis of the DepMap database (https://depmap.org/portal) retrieves negative Chronos scores for KDM6B in A-673 and TC-71 Ewing sarcoma cell lines, whereas KDM6A does not constitute a dependency in these cells (−0.05 and −0.15; 0.04 and 0.013, respectively), supporting the correlation of KDM6B with GGAA repeats.
