Elevated TERT Expression in TERT-Wildtype Adult Diffuse Gliomas: Histological Evaluation with a Novel TERT-Specific Antibody

Figure 3

TERT expression in human glioma samples. (a) TMab-6 immunostaining of the glioma samples demonstrated strong nuclear as well as some cytoplasmic staining in tumor cells. Representative tumors were shown in the astrocytic, oligodendroglial, IDH-wildtype GBM, and IDH-wildtype diffuse astrocytoma groups. Glioma cells in all the cases showed nuclear immunostaining of TERT to a various degree. (b) TMab-6 immunostaining of vascular endothelial cells (arrows) in the nonneoplastic cerebral tissues, TERT-wildtype AA, TERT-mutated AO, and TERT-mutated GBM. AA, anaplastic astrocytoma; AO, anaplastic oligodendroglioma; AOA, anaplastic oligoastrocytoma; GBM, IDH-wildtype glioblastoma; mt, mutation; wt/WT, wildtype. Scale bar = 40 μm.
