Expression levels of genes belonging to the respiratory chain subunits, within the inner membrane of mitochondria, in placentas from healthy control pregnancies and mothers infected with SARS-CoV-2 during the third trimester of pregnancy. (A) Placental NADH-dehydrogenase-1α subcomplex 9 (NDUFA9, complex I) gene expression levels. Data were significantly different among the three groups (Kruskal–Wallis test, p < 0.05). * p < 0.05 vs. controls (Mann-Whitney U test). (B) Placental Succinate DeHydrogenase complex subunit A (SDHA, complex II) gene expression levels. Data were significantly different among the three groups (Kruskal-Wallis test, p < 0.05). ** p = 0.01 vs. controls (Mann-Whitney U test). (C) Placental Cytochrome c OXidase subunit IV Isoform 1 (COX4I1, complex IV) gene expression levels. Data were not significantly different among the three groups. (D) Placental UbiQuinol-Cytochrome c Reductase Core protein I (UQCRC1, complex III) gene expression levels. Data were significantly different among the three groups (Kruskal–Wallis test, p < 0.05). ** p = 0.01 vs. controls (Mann-Whitney U test). Round circles are values that differ of more than 2 standard deviations from the median value.
