For each cell line, UUAGGG repeats signals from different blots were normalized to the corresponding 28S rRNA oligonucleotide-specific signals as an estimate of UUAGGG repeats content per transcriptome (UUAGGG/28S), averaged and expressed relative to the transcriptome-normalized UUAGGG repeats mean level in non-MLL-r leukemia cell lines. This evidence concerns the gene KMT2A and leukemia.
