When the UUAGGG/28S level of each cell line was divided by the corresponding MTL, we found transcriptome-normalized TERRA levels 1.8-fold higher in MLL-r than in non-MLL-r leukemia (p < 0.01) but not significantly different between lymphoid and myeloid leukemia (p = 0.098). The gene discussed is KMT2A; the disease is myeloid leukemia.
