In comparison with the HF group, Figure 7A,B shows increased phosphorylation level of Drp1S616 and PINK1 mRNA expression as well as relative unchanged total protein content of Drp1; Figure 7C,D shows increased content of Drp1 in mitochondria and decreased content of Drp1 in cytoplasm; Figure 7E,F shows a higher co-localization degree of Drp1 and mitochondria in the HP group. Here, PINK1 is linked to hydrops fetalis.
