Interestingly, the UW-228-2 medulloblastoma cell line showed almost no anti-BRCA2 antibody reactivity, while the other medulloblastoma cell line, D283MED, had BRCA2 protein amounts comparable to the CHLA-02-ATRT, LN229 GBM, and 293T cell lines (Figure S1 in Supplementary Material). This evidence concerns the gene BRCA2 and glioblastoma.
