(G) Splenocytes from Pacs1+/−;Bcl2TG and Pacs1−/−;Bcl2TG mice were stained with cell surface antibodies to identify FOB cells and treated with 100 µM H2O2 for 35 minutes. Cells were then labelled with TMRE to monitor MMP. TMRE fluorescence was measured by FACS analysis. Data are presented as mean ± SD of 3-4 replicates, unpaired t test, ns = not significant, ***P < 0.001. Results are from one experiment.
