CASP6 and chronic myelogenous leukemia, BCR-ABL1 positive: We compared these values to previously published ones of apoptotic gene expression in human monocytes displaying fold changes of >+5 for caspase 6117, in human chronic myelogenous leukemia K562 cells with fold changes of +1.779 and +1.633 for caspase 6 and caspase 8 respectively after chemical stimulation118, and various apoptosis induced genes in U937 cells showing fold changes >+ 2 after a combination of thermal and chemical stress119.
