(A) Representative traces depicting H2O2 production by
isolated brain mitochondria oxidizing glutamate and malate (G/M, 5 mM each)
before and after addition of DMSO (CTRL) or mdivi-1 (50 μM), followed by
addition of ADP (2 mM), and then rotenone (1 μM). (B) Quantification of
the data in (A) (mean ± SD, n=5). * p<0.05 compared
to control, @ p<0.05 compared to the respective condition with no ADP,
# p<0.05 for mdivi-1 rate after ADP compared to control rate after
ADP. Each rotenone (Rot) bar is the mean of 2 experiments. (C) Representative
traces depicting RET-mediated H2O2 production by brain
mitochondria incubated with succinate, followed by addition of CTRL or mdivi-1,
and then ADP (2 mM). (D) Quantification of the data in (C) (mean ± SD,
n=3). * p<0.05 compared to control.
