Abstract

Aldose reductase (AR) has been implicated in the etiology of diabetic cataract, as well as in other complications. However, the role of AR in these complications remains controversial because the strongest supporting evidence is drawn from the use of AR inhibitors for which specificity in vivo cannot be ascertained. To settle this issue we developed transgenic mice that overexpress AR in their lens epithelial cells and found that they become susceptible to the development of diabetic and galactose cataracts. When the sorbitol dehydrogenase-deficient mutation is also present in these transgenic mice, greater accumulation of sorbitol and further acceleration of diabetic cataract develop. These genetic studies demonstrated convincingly that accumulation of polyols from the reduction of hexose by AR leads to the formation of sugar cataracts.

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.
