TMT1B and glioblastoma: At the spatial level, METTL7B expression was higher in the infiltrating tumor (intermediate zone between leading edge and cellular tumor, ratio of tumor to normal cells: 10–20/100) and cellular tumor (tumor core) as compared to the leading edge (border of the tumor, ratio of tumor to normal cells: 1–3/100) (Ivy Glioblastoma Atlas Project, Figure S1G).
