MT3 and astrocytoma (excluding glioblastoma): It is interesting to notice, that grade I-III astrocytoma group consisted of one gemistocytic astrocytoma sample for which individual data dots plotted for MT1A, MT1E, MT2, and MT3 genes in mRNA expression plots were the largest observations reaching the upper whiskers value which corresponded to the 3-rd quartile of gene expression value in glioblastoma, respectively (Figs 1a,c, 2a,c, sample log2 (2−ddCt) value marked as a red dot).
