abstract = {A subset of Group 3 medulloblastoma frequently harbors
amplification or overexpression of MYC lacking additional
focal aberrations, yet it remains unclear whether MYC
overexpression alone can induce tumorigenesis and which
cells give rise to these tumors. Here, we showed that
astrocyte progenitors in the early postnatal cerebellum were
susceptible to transformation by MYC. The resulting tumors
specifically resembled human Group 3 medulloblastoma based
on histology and gene expression profiling. Gene expression
analysis of MYC-driven medulloblastoma cells revealed
altered glucose metabolic pathways with marked
overexpression of lactate dehydrogenase A (LDHA). LDHA
abundance correlated positively with MYC expression and was
associated with poor prognosis in human Group 3
medulloblastoma. Inhibition of LDHA significantly reduced
growth of both mouse and human MYC-driven tumors but had
little effect on normal cerebellar cells or SHH-associated
medulloblastoma. By generating a new mouse model, we
demonstrated for the first time that astrocyte progenitors
can be transformed by MYC and serve as the cells of origin
for Group 3 medulloblastoma. Moreover, we identified LDHA as
a novel, specific therapeutic target for this devastating
disease.},
