Parkin-mediated mitophagy evokes perinatal cardiac mitochondria maturation
Exclusion of Parkin from mitochondria of perinatal cardiomyocytes interrupts structural and molecular transformations essential to normal perinatal-adult mitochondrial replacement. mRNA-sequencing from cardiac total RNA was performed at P1, P21 and 5-week stages of nontransgenic (ntg) and human-Mfn2-overexpressing (Mfn2wt) hearts, and also of tet-off control (tetoff) and human-Mfn2 T111A/S442A-overexpressing (Mfn2AA) hearts. Overall design: Libraries from all P1 samples were prepared and analyzed together, and similarly all P21 libraries, and all 5-week libraries together.  To facilitate comparison across time points by accounting for batch effect, new libraries were prepared starting from total RNA from selected P21 ntg and 5-week ntg hearts subjected to prior analysis, during the same batch preparation as all P1 samples, and analyzed together.  Correction for differences observed between libraries prepared from the same total RNA, but at different times, allows comparison across timepoints.
