1. The TSDR of ATL cells exhibits Treg-like hypomethylated status or CD4+ conventional T cell–like methylated status.
The TSDR of ATL cells exhibits Treg-like hypomethylated status or CD4+ conventional T cell–like methylated status. Bisulfite sequencing was performed using genomic DNA from each sample. The frequency of the demethylation of CpG is shown. Yellow, hypomethylated; and blue, methylated in each CpG. A, the DNA methylation status in the TSDR of the HTLV-1–infected cell lines and primary ATL cells was analyzed, and all TSDR, from amplicons (amp) 1 to 11, are illustrated. MJ cell line was used as the TSDR-hypomethylated representative, and MT-1 cell line was used as the TSDR-methylated representative. For primary ATL cells, case 2 was used as the TSDR-hypomethylated representative, and case 17 was used as the TSDR-methylated representative. B, the DNA methylation status of the TSDR of a healthy donor and primary ATL cells. Tregs from a healthy donor were used as the TSDR-hypomethylated control, and CD4+CD25− conventional T cells from a healthy donor were used as the TSDR-methylated control. The number of primary ATL cells corresponds to each case number shown in Supplementary Table S1. The data shown are the sum of three independent experiments.
