We next analyzed the correlation between the c‐Myc level and killing activity of WBC100 in various hematological tumor cell lines and found that the killing activity of WBC100 against tumor cells correlated with the c‐Myc protein level (r = −0.65, p = 0.0008) (Figure 1C) but did not correlate with the nuclear XPB protein level (r = −0.05, p = 0.83) (Figure S1G,I, Supporting Information). The gene discussed is ERCC3; the disease is neoplasm.
