Incorporation of the elderberry anthocyanins by endothelial cells increases protection against oxidative stress

Abstract

The objective of this study was to investigate the ability of endothelial cells (EC) to incorporate anthocyanins and to examine their potential benefits against various oxidative stressors. Endothelial dysfunction has been proposed to play an important role in the initiation and development of vascular disease, with studies having shown that administration of antioxidants improves endothelial function. Elderberry extract contains 4 anthocyanins, which where incorporated into the plasma membrane and cytosol of EC following 4 h incubation at 1 mg.ml(-1). However, incorporation within the cytosol was considerably less than that in the membrane. Uptake within both regions appeared to be structure dependent, with monoglycoside concentrations higher than that of the diglucosides in both compartments. The enrichment of EC with elderberry anthocyanins conferred significant protective effects in EC against the following oxidative stressors: hydrogen peroxide (H(2)O(2)); 2, 2'-azobis(2-amidinopropane) dihydrochloride (AAPH); and FeSO(4)/ascorbic acid (AA). These results show for the first time that vascular EC can incorporate anthocyanins into the membrane and cytosol, conferring significant protective effects against oxidative insult. These findings may have important implications on preserving EC function and preventing the initiation of EC changes associated with vascular diseases.

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.
