Abstract

A stable ascorbic acid derivative, 2-O-α-glucopyranosyl-l-ascorbic acid (AA-2G), was evaluated and compared with ascorbic acid for its protective effect against cellular damage and senescence induced by hydrogen peroxide (H(2)O(2)). Pretreatment with AA-2G for 72 h promoted the proliferation of normal human dermal fibroblasts (NHDF) and protected against cell damage induced by H(2)O(2). In contrast, ascorbic acid increased the proliferation and protected against cell damage, only when culture medium containing ascorbic acid was replaced every 24 h during the pretreatment period. These results suggest that the effect of AA-2G is longer-lasting compared to that of ascorbic acid. Senescence associated-β-galactosidase (SA-β-gal) activity, a classical biomarker of cellular senescence, was increased in H(2)O(2)-exposed NHDF cells, but pretreatment or posttreatment with ascorbic acid or AA-2G significantly inhibited the increase in SA-β-gal levels. AA-2G was more potent than ascorbic acid in down-regulating SA-β-gal activity. Expression of SIRT1, which has attracted attention as an anti-aging factor in recent years, was significantly decreased in H(2)O(2)-exposed NHDF cells compared to untreated cells. However, pretreatment NHDF cells with AA-2G before H(2)O(2) exposure significantly inhibited this decrease in SIRT1 expression, whereas ascorbic acid had no effect. After H(2)O(2) exposure, the expression levels of p53 and p21 were increased in NHDF cells and pretreatment with AA-2G inhibited this increase. Together, these results suggest that AA-2G protects dermal fibroblasts from oxidative stress and cellular senescence. These characteristics indicate that AA-2G could become a promising material for its anti-aging properties.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The effect of AA-2G is longer-lasting compared to that of AA against cellular damage and senescence induced by hydrogen peroxide.

    “The results suggest that the effect of AA-2G is longer-lasting compared to that of AA and this derivative might therefore be considered as a more stable form of vitamin C [130].”

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.
