Outline of Final Research Achievements |
1. Lysosomal accumulation of mitochondrial subunit c in cathepsin D (CD) deficient neurons were completely inhibited in neurons doubly deficient in CD and Atg7 and only partially reduced in neurons doubly deficient in CD and parkin, indicating the limited contribution of mitophagy mediated by parkin in the mitochondrial quality control in neurons. 2. Intercrossing of the transgenic (Tg) mice expressing iron regulatory protein 2 (IRP2) to Parkin knockout mice perturbed the integrity of neurons specifically in the substantia nigra and provoked motor symptoms. 3. Therefore, we produced antibodies specific to mouse DFCP1, a marker for omegasomes. In HeLa cells under normal conditions, dotted or tubular immunoreactivity for DFCP1 was found along Tom20-positive mitochondria. Moreover, under starved conditions, DFCP1-positive structures were co-localized in one part of the LC3-positive autophagosomes.
