HAP1 and chronic myelogenous leukemia, BCR-ABL1 positive: To investigate whether the PA-induced membrane phenotypes occur in other cell types, parental HAP1 (a near-haploid cell line derived from a patient with chronic myeloid leukemia [44]) and HAP1 AdipoR2 knockout cells were treated with 0 μM PA (basal), 50 μM PA, 200 μM PA and 200 μM PA/100 μM OA.(Fig. 6A-B).
