Manipulating mitochondrial gene expression
Bibliographic record
Abstract
Mitochondria are essential for cellular metabolism, serving as the primary source of adenosine triphosphate (ATP). This energy is generated by the oxidative phosphorylation (OXPHOS) system located in the inner mitochondrial membrane. Impairments in this machinery are linked to serious human diseases, especially in tissues with high energy demands. Assembly of the OXPHOS system requires the coordinated expression of genes encoded by both the nuclear and mitochondrial genomes. The mitochondrial DNA encodes for 13 protein components, which are synthesized by mitochondrial ribosomes and inserted into the inner membrane during translation. Despite progress, key aspects of how mitochondrial gene expression is regulated remain elusive, largely due to the organelle's limited genetic accessibility. However, emerging technologies now offer new tools to manipulate various stages of this process. In this review, we explore recent strategies that expand our ability to target mitochondria genetically.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
