Abstract

fetched live from OpenAlex

Alterations in contractile activity influence the intracellular homeostasis of muscle, which results in adaptations in the performance and the phenotype of this tissue. Denervation is an effective disuse model that functions to change the intracellular environment of muscle leading to a rapid loss in mass, a decrease in mitochondrial content, and an elevation in both proapoptotic protein expression and myonuclear apoptosis. Recent investigations have shown that alternative degradation pathways such as autophagy are activated in conjunction with apoptosis during chronic muscle disuse. We have previously shown that seven days of muscle disuse increases the expression of Beclin 1. Furthermore, we have also detected a significant increase in the expression of LC3-II, a known component of autophagy. In addition to its upregulation, denervation appears to induce the translocation of LC3-II to mitochondrial membranes. Collectively, these increases in protein expression suggest that autophagy signaling is upregulated in response to denervation, and that these pathways may preferentially target mitochondria for degradation in skeletal muscle.

Teacher imitation

Not 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.
