mtDNA replication and maintenance (A) The normalized ratios of steady-state levels of replication termination versus replication elongation events of control (C; N = 7) and rescue (R; N = 5) heart samples, as determined by quantitative real-time PCR are shown. Data are presented as means ± SEM percentage of controls; *P < 0.05. (B) Southern blot analysis of mtDNA copy number in comparison with 18S DNA demonstrate a significant reduction of mtDNA levels in KO (8%; N = 7) and heterozygous KO (HET) (62%; N = 3), and a modest reduction in R (80%; N = 8; P = 0.075) in comparison with control samples (N = 10).
