    Journal:  UQCRC1 deficiency impairs mitophagy via PINK1-dependent mechanisms in Parkinson's disease. (Pubmed Central) -  Jan 16, 2026   
    Treatment with two PINK1 activators, kinetin and MTK458, resulted in similar protective effects in the fly and cell models. Overall, we identified OXPHOS stress led by deficiency of UQCRC1 as an etiology of mitophagy defects in PD and PINK1 as a therapeutic target for UQCRC1-associated PD.

    Journal:  Putative PINK1/Parkin activators lower the threshold for mitophagy by sensitizing cells to mitochondrial stress. (Pubmed Central) -  Aug 31, 2025   
    Here, we characterize two mitophagy activators: a novel Parkin activator, FB231, and the reported PINK1 activator MTK458...Our findings support a model whereby weak or "silent" mitochondrial toxins potentiate other mitochondrial stressors, enhancing PINK1/Parkin-mediated mitophagy. These insights highlight important considerations for therapeutic strategies targeting mitophagy activation in Parkinson's disease.
