Abstract

fetched live from OpenAlex

Mutations in mitochondrial DNA are frequent in cancer and the accompanying mitochondrial dysfunction and altered intermediary metabolism might contribute to, or signal, tumour pathogenesis. The metabolism of human prostate peripheral zone glandular epithelial cells is unique. Compared with many other soft tissues, these glandular epithelial cells accumulate high concentrations of zinc, which inhibits the activity of m-aconitase, an enzyme involved in citrate metabolism through Krebs cycle. This causes Krebs cycle truncation and accumulation of high concentrations of citrate to be secreted in prostatic fluid. The accumulation of zinc also inhibits terminal oxidation. Therefore, these cells exhibit inefficient energy production. In contrast, malignant transformation of the prostate is associated with an early metabolic switch, leading to decreased zinc accumulation and increased citrate oxidation. The efficient energy production in these transformed cells implies increased electron transport chain activity, increased oxygen consumption, and perhaps, excess reactive oxygen species (ROS) production compared with normal prostate epithelial cells. Because ROS have deleterious effects on DNA, proteins, and lipids, the altered intermediary metabolism may be linked with ROS production and accelerated mitochondrial DNA mutations in prostate cancer.

Full frame distilled prediction

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.
