VASH2 and medulloblastoma: In this study, we explored the potential correlation between the high expression level of VASH2 and the pathological features of medulloblastoma (e.g., SHH subtype) using immunohistochemical techniques, and we also found that the lowest expression level of VASH2 was found in children with WNT-type medulloblastoma, suggesting that VASH2 may be a potential diagnostic target for predicting the molecular subtype of medulloblastoma.
