Next, to determine the actual rather than predicted full-length sequence of FTO-lncAML transcripts, we performed rapid amplification of cDNA ends (RACE) in Fujioka AML cells (Figures 4A and 4B), making use of the Cufflinks-predicted exon structure of FTO-lncAML to design appropriate primers. This evidence concerns the gene FTO and acute myeloid leukemia.
