First of all, across 17 analyses, AXIN2 (Median rank 178, P < 0.05) was highly expressed in various tumors compared to normal tissue, while CASP9 (Median rank 28, P < 0.05) showed higher expression only in medulloblastoma in the Oncomine (Figure S1). This evidence concerns the gene CASP9 and medulloblastoma.
