abstractText | The BCR-ABL1 fusion protein is the cause of chronic myeloid leukemia (CML) and of a significant fraction of adult-onset B cell acute lymphoblastic leukemia (B-ALL) cases. Using mouse models and patient-derived samples, we identified an essential role for gamma-catenin in the initiation and maintenance of BCR-ABL1(+) B-ALL but not CML. The selectivity was explained by a partial gamma-catenin dependence of MYC expression together with the susceptibility of B-ALL, but not CML, to reduced MYC levels. MYC and gamma-catenin enabled B-ALL maintenance by augmenting BIRC5 and enforced BIRC5 expression overcame gamma-catenin loss. Since gamma-catenin was dispensable for normal hematopoiesis, these lineage- and disease-specific features of canonical Wnt signaling identified a potential therapeutic target for the treatment of BCR-ABL1(+) B-ALL. |
