Recent studies demonstrate that NUPs play fundamental roles in cancer pathogenesis by dysregulating key NPC functions and driving tumorigenesis and disease progression. NUPs and NPC-regulated mechanisms can be pharmacologically targeted, providing a strong rationale for developing much-needed innovative therapeutic strategies to combat cancer.
UNLABELLED: The nuclear pore complex (NPC) and its building-block proteins, nucleoporins (NUP), play fundamental roles in maintaining cellular fitness by regulating nucleocytoplasmic transport, chromatin and transcriptional activity, and genome stability. These core biological processes are critical for cancer cells, and thus, tumor-driven co-option of NUP-regulated functions has emerged as an important mechanism contributing to the pathogenesis of multiple malignancies. This review discusses how NUP dysregulation mechanistically contributes to tumor initiation and progression and how these insights open opportunities for innovative anticancer therapies, including using clinical-grade molecular glues that induce selective NUP degradation and pharmacologically inhibiting NPC-regulated epigenomic/transcriptomic signaling and nucleocytoplasmic transport.
