Ironomycin induces mantle cell lymphoma cell death by targeting iron metabolism addiction.

ABSTRACT: Rationale: Mantle-cell lymphoma (MCL) remains an aggressive and incurable cancer. Accumulating evidence reveals that abnormal iron metabolism plays an important role in tumorigenesis and in cancer progression of many tumors. Based on these data, we searched to identify alterations of iron homeostasis in MCL that could be exploited to develop novel therapeutic strategies. Methods: Analysis of the iron metabolism gene expression profile of a cohort of patients with MCL enables the identification of patients with a poor outcome who might benefit from an iron homeostasis-targeted therapy. We analyzed the therapeutic interest of ironomycin, known to sequester iron in the lysosome and to induce ferroptosis. Results: In a panel of MCL cell lines, ironomycin inhibited MCL cell
