How does GFM1 loss mechanistically link mitochondrial translation defects to enhanced mitophagy activation?

While the study demonstrates both impaired mitochondrial function and increased mitophagy markers (HSP90, TOMM20, PINK1), the causal relationship between translation defects and mitophagy induction is not explained. This connection is critical for understanding cellular protective responses in mitochondrial diseases.
