Multiple myeloma is an incurable hematological malignancy evolving from precursor states to advanced phases of the disease. MYC abnormalities play a critical role in the disease progression. Nevertheless, MYC lacks therapeutic drugability, thereby necessitating the exploration of alternative strategies aimed at circumventing the challenges associated with targeting MYC. In this study, we hypothesized that MYC upregulation induces genomic dependencies in tumor cells, creating vulnerabilities that can be exploited therapeutically. We discovered a differential dependency on glutamine metabolism in MYC overexpressing cells. We functionally explored these dependencies as a selective targetable vulnerability in vitro and in vivo. Furthermore, we uncovered a potential synergistic combination that can exacerbated this metabolic vulnerability, Collectively, our in vitro and in vivo results revealed an effective therapeutic combinatory strategy in the context of MYC overexpressing MM.
