To further characterize the relationship of MXRA5 expression level and tumor specimens, we measured the MXRA5 protein level in glioma tissue samples from twenty-eight patients (1 with grade I glioma, 7 with grade II glioma, 7 with grade III glioma, and 13 with GBM) using IHC analysis. Here, MXRA5 is linked to glioblastoma.
