Abstract

fetched live from OpenAlex

The dose-limiting side effect of taxane, platinum-complex, and other kinds of anticancer drugs is a chronic, distal, bilaterally symmetrical, sensory peripheral neuropathy that is often accompanied by neuropathic pain. Work with animal models of these conditions suggests that the neuropathy is a consequence of toxic effects on mitochondria in primary afferent sensory neurons. If this is true, then additional mitochondrial insult ought to make the neuropathic pain worse. This prediction was tested in rats with painful peripheral neuropathy due to the taxane agent, paclitaxel, and the platinum-complex agent, oxaliplatin. Rats with established neuropathy were given 1 of 3 mitochondrial poisons: rotenone (an inhibitor of respiratory Complex I), oligomycin (an inhibitor of adenosine triphosphate synthase), and auranofin (an inhibitor of the thioredoxin-thioredoxin reductase mitochondrial antioxidant defense system). All 3 toxins significantly increased the severity of paclitaxel-evoked and oxaliplatin-evoked mechano-allodynia and mechano-hyperalgesia while having no effect on the mechano-sensitivity of chemotherapy-naïve rats. Chemotherapy-evoked painful peripheral neuropathy is associated with an abnormal spontaneous discharge in primary afferent A fibers and C fibers. Oligomycin, at the same dose that exacerbated allodynia and hyperalgesia, significantly increased the discharge frequency of spontaneously discharging A fibers and C fibers in both paclitaxel-treated and oxaliplatin-treated rats, but did not evoke any discharge in naïve control rats. These results implicate mitochondrial dysfunction in the production of chemotherapy-evoked neuropathic pain and suggest that drugs that have positive effects on mitochondrial function may be of use in its treatment and prevention.

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.
