Resveratrol Increases Mitochondrial Protein Import in Differentiated PC12 Cells
Bibliographic record
Abstract
Mitochondrial function is dependent upon mitochondrial protein import (MPI), a complex process that transports nuclear-encoded proteins into mitochondria. Little is known about MPI in neurons. We examined the effects of Resveratrol (RSV), a polyphenolic antioxidant compound from grapes, on MPI in a neuronal cell model, differentiated PC12 cells. RSV (50µM, 24h) increased levels of mtGFP, a nuclear encoded mitochondrially targeted green fluorescent protein, and mtHsp70, a physiological mitochondrial heat shock protein, in mitochondria. In addition RSV also increased levels of Tom20, a key translocase of the outer mitochondrial membrane. The RSV mediated increases in mitochondrial proteins were independent of increases in mitochondrial mass or changes in intramitochondrial degradation. RSV also reduced mitochondria membrane potential and decreased basal levels of reactive oxygen species. Taken together, these findings show that RSV increases MPI and that this effect may be an important mechanism in the reported neuroprotective effects of RSV.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
