Abstract

Myeloid cancers such as myelodysplastic syndromes (MDS) and acute myeloid leukemia (AML) remain resistant to standard of care (SOC) and targeted therapies. In this study, we demonstrate that responsiveness to therapy is associated with activation of β-catenin-JAG1 in osteoblastic cells of patients treated with all-trans-retinoic acid (ATRA). ATRA suppresses β-catenin activity in patients and leukemic mice. Consequently, it inhibits the growth and survival of MDS/AML cells from patients with active β-catenin-JAG1 signaling and promotes their differentiation. This occurs independently of cytogenetics and mutational profile. ATRA also improves disease outcome in mice with no evidence of relapse and a superior safety profile to SOC. A human anti-JAG1 antibody improves efficacy in leukemic mice and patient-derived MDS/AML cells. β-catenin activation provides an explanation for the differential response to ATRA and a mechanistic biomarker for ATRA repurposing in myeloid malignancies, potentially evading relapse and extending across a broad range of cancers.

期刊介绍： Cancer Cell is a journal that focuses on promoting major advances in cancer research and oncology. The primary criteria for considering manuscripts are as follows: Major advances: Manuscripts should provide significant advancements in answering important questions related to naturally occurring cancers. Translational research: The journal welcomes translational research, which involves the application of basic scientific findings to human health and clinical practice. Clinical investigations: Cancer Cell is interested in publishing clinical investigations that contribute to establishing new paradigms in the treatment, diagnosis, or prevention of cancers. Insights into cancer biology: The journal values clinical investigations that provide important insights into cancer biology beyond what has been revealed by preclinical studies. Mechanism-based proof-of-principle studies: Cancer Cell encourages the publication of mechanism-based proof-of-principle clinical studies, which demonstrate the feasibility of a specific therapeutic approach or diagnostic test.
