NCR3LG1 and acute myeloid leukemia: We therefore calculated a Pearson correlation coefficient for all primary AML samples depicted in Figure 2 and revealed no significant correlation of cytotoxic activity observed for IFN-γ in response to B7H6 mRNA transcript levels (r = −0.20, p = 0.669) or surface expression (r = 0.57, p = 0.238).
