Abstract
Therapy resistance is frequently observed in cancer patients with distant metastases and effective management of metastatic disease remains challenging. Unraveling the cellular mechanisms and molecular targets fueling metastatic spread is crucial for advancing cancer therapies. In a recent issue of Cancer Discovery, Dashzeveg and colleagues revealed that loss of terminal sialylation in glycoproteins within circulating tumor cell clusters is a dynamic process that contributes to cellular dormancy, facilitates evasion of chemotherapy, and enhances metastatic seeding. Furthermore, the study identifies the glycoprotein podocalyxin (PODXL) as a potential target for counteracting the metastasis of quiescent tumor cells associated with paclitaxel treatment in triple-negative breast cancer.
