Targeting the insulin-like growth factor-1 receptor to overcome imatinib resistance in chronic myeloid leukemia.

ABSTRACT: Patients with chronic myeloid leukemia (CML) frequently develop resistance to tyrosine kinase inhibitors such as imatinib. In this study, we explored the role of the insulin-like growth factor 1 (IGF-1) signaling pathway in CML and imatinib resistance. An analysis of IGF-1 gene expression using public databases revealed elevated levels of insulin-like growth factor-binding proteins in patients with chronic-phase CML. Further research revealed that IGF-1-related genes were upregulated in patients who were unresponsive to imatinib, suggesting that IGF-1 signaling plays a role in the resistance mechanism. Furthermore, we evaluated the efficacy of linsitinib, a selective insulin-like growth factor-1 receptor (IGF-1R) inhibitor, in inhibiting the growth of CML cell lines, including imatinib-res
