Figure 6. POLDIP2 KO reduced mitochondrial superoxide. (A) Analysis of mitochondrial superoxide levels in WT and POLDIP2 KO samples. MitoSox fluorescence is presented as fold change compared to WT control. N-acetyl-L-cysteine (NAC) was used as a positive control. (B) Analysis of mitochondrial membrane potential in WT and POLDIP2 KO samples. TMRM fluorescence is presented as fold change compared to WT control. Carbonyl cyanide 3-chlorophenylhydrazone (CCCP) was used as a positive control. Results are presented as mean ± SEM of 2 biological repeats, each with 3 technical repeats. n.s. not significant, * p<0.05 and *** p<0.001.
