Although G0S2 expression alone in this study had no effect on apoptosis of CML cells, G0S2 increased imatinib‐mediated apoptosis when ATGL expression was low (BP‐CML, Figure 3B; shATGL, Figure 6E), implying that ATGL abrogates the effects of G0S2 on apoptosis. This evidence concerns the gene PNPLA2 and chronic myelogenous leukemia, BCR-ABL1 positive.
