Fig. 8: Graphic abstract of the role and signaling mechanism of Eftud2 in medulloblastoma progression.

Conditional knockout of Eftud2 in cerebellar granule precursor cells significantly extends survival in SHH medulloblastoma mice, highlighting its critical role in tumor progression. Mechanistically, Eftud2 upregulation promotes medulloblastoma cell proliferation by activating the SHH pathway. This occurs in part through Eftud2-mediated Kif3a exons 10–11 skipping, which enhances Gli2 transcriptional activity and drives oncogenic signaling.
