β-Catenin Is a Candidate Therapeutic Target for Myeloid Neoplasms with del(5q).

ABSTRACT: Deletion of the chromosome 5q [del(5q)] is one of the most common cytogenetic abnormalities observed in patients with de novo myelodysplastic syndromes (MDS) and therapy-related MDS or acute myeloid leukemia (t-MDS/tAML). Emerging evidence indicates that activation of the Wnt/β-catenin pathway contributes to the development of myeloid neoplasms with del(5q). Whether β-catenin is a potential therapeutic target for myeloid neoplasms with del(5q) has yet to be evaluated. Here, we report that genetic deletion of a single allele of β-catenin rescues ineffective hematopoiesis in an Apc haploinsufficient mouse model, which recapitulates several characteristic features of the preleukemic stage of myeloid neoplasms with a -5/del(5q). In addition, loss of a single allele of β-catenin r
