PTPRC and leukemia: Next, we measured the frequencies of YFP+ leukemia cells in the peripheral blood of WT and ChREBP-null (ChREBP+/+ and ChREBP−/− hereafter) recipient mice (Supplementary Figure 1A–1B), which only expressed myeloid cell markers (Mac-1 and Gr-1, Supplementary Figure 1C–1D), but not lymphoid cell markers (CD3 and B220, Supplementary Figure 1E–1F).
