Abstract
Mutations in mitochondrial DNA (mtDNA) cause excessive production of mitochondrial reactive oxygen species (ROS) and shorten animal life span. We examined the mechanisms responsible for removal of mitochondria with deleterious mtDNA mutations by autophagy. Incubation of primary cells and cell lines in the absence of serum promotes autophagy of mitochondria with deleterious mtDNA mutations but spares their normal counterparts. The effect of serum withdrawal on the autophagy of dysfunctional mitochondria is prevented by the addition of IGF-1. As a result of the elimination of mitochondria with deleterious mutations, excessive ROS production, characteristic of dysfunctional mitochondria, is greatly reduced. Mitochondrial autophagy shares a common mechanism with mitochondrial-induced cell apoptosis, including mitochondrial transition pore formation and increased ROS production.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
