Reintroduction of StarD7 into the StarD7-KO C2C12 cells restored mitochondrial PC composition. Mitochondria were purified from WT + EV, KO + EV, and KO + StarD7 C2C12 cells, phospholipids were extracted, and the amounts of (a) PC and (b) PE were determined using LC-MS/MS with multiple reaction monitoring. Values were normalized against the amount of mitochondrial protein. The results shown are from one representative experiment of five experiments giving similar results. Data are means ± S.D. from quadruplet analyses of one experiment. **P < 0.01 and ***P < 0.001 as compared with WT + EV cells. †P < 0.05, ††P < 0.01, and †††P < 0.001 as compared with KO + EV cells (one-way ANOVA with Tukey’s post hoc test).
