Abstract

Nerve conduction impairment in experimental diabetes has been empirically but not mechanistically linked to altered nerve myo-inositol metabolism. The phospholipid-dependent membrane-bound sodium-potassium ATPase provides a potential mechanism to relate defects in diabetic peripheral nerve myo-inositol-phospholipid metabolism, impulse conduction, and energy utilization. Therefore, the effect of streptozocin-induced diabetes mellitus and dietary myo-inositol supplementation on rat sciatic nerve sodium-potassium ATPase was studied. ATPase activity was measured enzymatically in sciatic nerve homogenates from 4-wk streptozocin diabetic rats and age-matched controls either fed a standard or 1% myo-inositol supplemented diet. The sodium-potassium ATPase components were assessed by ouabain inhibition or the omission of sodium and potassium ions. Diabetes reduced the composite ATPase activity recovered in crude homogenates of sciatic nerve. The 40% reduction in the sodium-potassium ATPase was selectively prevented by 1% myo-inositol supplementation (which preserved normal nerve conduction). Thus, in diabetic peripheral nerve, abnormal myo-inositol metabolism is associated with abnormal sodium-potassium ATPase activity. The mechanism of the effect of dietary myo-inositol to correct diabetic nerve conduction may be through changes in a sodium-potassium ATPase, possibly via changes in myo-inositol-containing phospholipids.

  • Chronic hyperglycemia enhances formation of advanced glycation end-products (AGEs), which bind to specific receptors (RAGE) and activate inflammatory pathways.

    “Chronic hyperglycemia enhances formation of advanced glycation end-products (AGEs), which bind to specific receptors (RAGE) and activate inflammatory pathways.”

    From Diabetic gastroparesis: pathophysiology and impact on insulin timing choices (2026) · cites this paper as [35]

    The Introduction and the section “Effect of streptozocin diabetes and dietary MI” discuss hyperglycemia in relation to myo-inositol uptake, polyol-pathway activity, and nerve sodium-potassium ATPase. Searches for advanced glycation end-products, RAGE, and inflammatory pathways found no passage addressing the claimed mechanism in our copy; page numbers were not provided. (LLM, conf=0.77)

  • Activation of the polyol pathway further increases oxidative stress, damaging neurons and endothelial cells and reducing blood supply to neural tissues.

    “Activation of the polyol pathway further increases oxidative stress, damaging neurons and endothelial cells and reducing blood supply to neural tissues [33–37].”

    From Diabetic gastroparesis: pathophysiology and impact on insulin timing choices (2026) · cites this paper as [35]

    The Introduction and the section on streptozocin diabetes and dietary myo-inositol suggest that increased polyol-pathway activity may lower nerve myo-inositol and impair nerve function. Our copy does not address the claimed oxidative-stress mechanism, damage to endothelial cells, or reduced blood supply to neural tissue (searched: oxidative stress, endothelial cells, vascular blood flow).

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
