doi: 10.3390/cells15090806
Figure Lengend Snippet: Low-dose CCCP treatment rescues impaired mitophagy and blastocyst formation defects caused by Muc1 knockout. ( A ) Morphological comparison of D0.5, D1.5, D3.0, D3.5, and D4.5 WT, KO, WT + CCCP, and KO + CCCP embryos. Scale bar: 50 µm. White arrows indicate embryos with developmental arrest. ( B ) Blastocyst formation rates in WT, KO, WT + CCCP, and KO + CCCP groups. Number of samples analyzed in each group: WT = 37, KO = 45, WT + CCCP = 37, and KO + CCCP = 48 (analyzed using Chi-square test). ( C ) Immunofluorescence staining of MitoSOX in WT, KO, WT + CCCP, and KO + CCCP groups at the blastocyst stage. Blue, DNA; red, MitoSOX. Scale bar: 10 µm. ( D ) Relative fluorescence intensity of MitoSOX at the blastocyst stage. Number of samples analyzed in each group was as follows: WT = 20, KO = 21, WT + CCCP = 20, and KO + CCCP = 20 (analyzed using ANOVA). ( E ) Immunofluorescence staining of LC3 and MitoTracker in WT, KO, WT + CCCP, and KO + CCCP groups at the blastocyst stage. Blue, DNA; green, LC3; red, MitoTracker. Scale bar: 10 µm. White arrows indicate the co-localization of LC3 and MitoTracker. ( F ) Pearson correlation coefficient for co-localization of LC3 and MitoTracker at the blastocyst stage. Number of samples analyzed in each group: WT = 23, KO = 20, WT + CCCP = 22, and KO + CCCP = 20 (analyzed using ANOVA). Data in ( B , D , F ) are means ± SDs from at least three independent experiments. ns: not significant.
