Expression of OXPHOS complexes in WHO grade I (meningothelial), II (atypical), and III (anaplastic) meningiomas. (A, G, and M) porin; (B, H, and N) complex I; (C, I, and O) complex II; (D, J, and P) complex III; (E, K, and Q) complex IV; (F, L, and R) complex V. (A–F) Meningothelial meningioma (MM1) with a complex II deficiency and a reduction of complexes I and IV (Supplementary Table 1). (G–L) Atypical meningioma (AM4) with an isolated complex I deficiency (Supplementary Table 1). (M–R) Combined low complexes I, II, and IV in an anaplastic meningioma (ANM1). (H) Staining intensity = 0; 20× magnification. Scale bar = 100 µm.
