Enzymatic activities of the OXPHOS complexes and the citrate synthase in meningiomas, PNSTs, and control brain tissue. (A) Citrate synthase (CS) activity; (B) complex I activity; (C) complex II activity; (D) complex III activity; (E) complex IV activity; (F) complex V activity. Absolute enzyme activities are given in mUnits/mg protein. The activities were compared with normal brain tissue. Values are given as mean ± SEM. *P < .05; **P < .01. (G) Immunoblot analysis of meningiomas and PNSTs (for details on tumors, see Supplementary Table 1) and control brain tissue. BC: control brain; n = 5; NF: n = 4; SW: n = 4; FM: n = 4; MM: n = 5; TM: n = 4; PM: n = 4; AM: n = 5; ANM: n = 3.
