To assess a potential influence of PTP expression on nilotinib response, 38 PTPs (Supplementary Table 1) were considered, which were previously shown to be expressed in hematopoietic cells including myeloid leukemia [18, 19], or have previously been shown to be dysregulated in cancer cells [9, 20, 21]. The gene discussed is PTS; the disease is myeloid leukemia.
