Analysis of an available array dataset [40] revealed a significantly lower mRNA expression of CAMKK2 in infiltrating astrocytic tumors (n = 5, p = 0.01), ependymoma (n = 4, p = 0.002), and oligodendroglioma (n = 5, p = 0.03) compared to normal brain tissue (n = 4, Fig 4C). This evidence concerns the gene CAMKK2 and ependymoma.
