Figure 5. Pink1 stabilized Fbxo7 in SNc of mouse brain. The different parts of brain tissues were dissected from WT and Pink1 KO female mice with age of 13-16 weeks. The homogenates were analyzed by western blot to check the protein level of Fbxo7 (A–C: The protein level of Fbxo7 was normalized to β-Actin, then the relative level of Fbxo7 from WT was further normalized to that from KO). The relative ratios were shown as mean ± SD; n = 4 independent experiments; unpaired 2-tailed Student’s t test; **p = 0.0028 for SNc; p = 0.5588 for Stratium; p = 0.9763 for Cortex. (D) the mRNAs of Fbxo7 from SNc of WT and KO were analyzed by RT-qPCR. The relative ratios were shown as mean ± SD; n ≥ 5 independent experiments; unpaired 2-tailed Student’s t test; p = 0.392. (E) expression of Pink1 had no effect on Fbxo7 in HEK 293A cells. The relative ratios were shown as mean ± SD; n = 3 independent experiments; unpaired 2-tailed Student’s t test; p = 0.8255.
