PRTN3 and myelodysplastic syndrome: For example, ID1, APOE, and CD14 were expressed by MDS low-risk cells from the myeloid cluster whereas MPO, PRTN3, and AZU1 genes were expressed by wild-type BU3.10 cells, revealing changes in myeloid composition between control and MDS low-risk cells (Fig. 7H, Supplementary Fig. 8D and Supplementary Data Table 4).
