Medulloblastoma (MB) is a highly heterogeneous and one of the most malignant pediatric brain tumors, comprising four subgroups: Sonic Hedgehog, Wingless, Group 3, and Group 4.Group 3 MB has the worst prognosis of all MBs.However, the molecular and cellular mechanisms driving the maintenance of malignancy are poorly understood.Here, we employed high-throughput single-cell and bulk RNA sequencing to identify novel molecular features of Group 3 MB, doorking 1835-080 and found that a specific cell cluster displayed a highly malignant phenotype.

Then, we identified the glutamate receptor metabotropic 8 (GRM8), and AP-1 complex subunit sigma-2 (AP1S2) genes as two mega motion lc100 critical markers of Group 3 MB, corresponding to its poor prognosis.Information on 33 clinical cases was further utilized for validation.Meanwhile, a global map of the molecular cascade downstream of the MYC oncogene in Group 3 MB was also delineated using single-cell RNA sequencing.Our data yields new insights into Group 3 MB molecular characteristics and provides novel therapeutic targets for this relentless disease.
