NKX2-2 and classic Hodgkin lymphoma: We compared NKX2-2 expressing DEV with four control cell lines (GSE40160, Supplementary Table 1), four cHL patients expressing high NKX2-2 levels with four negative controls (GSE39134, Supplementary Table 2), and one NLPHL patient expressing high levels of NKX2-2 with six negative controls (GSE7788, Supplementary Table 3).
