Differential Alterations of the Mitochondrial Morphology and Respiratory Chain Complexes during Postnatal Development of the Mouse Lung

mRNA expression of the complex II–V genes in new born, P15, and adult lung tissues as determined by real-time PCR analyses. Total RNA was extracted from lung tissue of newborn (NB), P15, and adult (AL) mice using RNAzol, reverse transcribed and subjected to qRT-PCR using specific primers for mRNAs of (a) the nuclear-encoded succinate dehydrogenase complex II subunit D (Sdhd), (b) the mitochondrially encoded complex III (mt-Cytb), (c–e) the different complex IV subunits (mt-Co1, mt-Co2, and mt-Co3), and (f) the mitochondrially encoded complex V (mt-Atp6). The bar graphs represent relative levels of the transcripts in three independent experiments. values were calculated by the one-way ANOVA using Tukey’s test. Statistical significance is indicated by , , , and . The mRNA levels were normalized to the ones of GAPDH.
