Isolation and Properties of Lens Aldose Reductase

Abstract

Exposure of the lens of the eye to a high concentration of an aldose, such as n-glucose, n-galactose, or n-xylose, results in the accumulation of the corresponding sugar alcohols. The high concentration which t.hese alcohols reach within the lens fibers appears to be responsible for t,he loss of clarity of the lens that is observed in experimental sugar cataracts (1). The reduced triphosphopyridine nucleotide-dependent reduction of aldoses to polyols by extracts of seminal vesicles and placenta has been investigated by Hers (2, 3) who named the enzyme aldose reductase. A similar enzymatic activity was first described in the lens by van Heyningen (4) and was studied in more detail by Kinoshita et al. (5). Although lens aldose reductase plays a central role in the etiology of sugar cataracts, t,he detailed properties of this enzyme have not previously been determined. It is the purpose of this report to present a method for the preparation of this enzyme and a description of its properties.

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.
