To analyse a possible effect of LASP1 on TKI‐induced cell death in CML, we investigated apoptosis (Figure S2) and cell cycle arrest (Figure S3) in the four generated K562 cell lines using Annexin‐V and propidium iodide (PI) staining, respectively. Here, LASP1 is linked to chronic myelogenous leukemia, BCR-ABL1 positive.
