Abstract

Monocyte adhesion to the vascular endothelium and their subsequent trans-endothelial migration are pivotal early events in atherogenesis. In this study, the effect of delphinidin, belonging to the group of anthocyanin, on adhesion of monocytes to endothelial cells induced by ox-LDL was investigated. The results showed that the pre-treatment with delphinidin (50, 100, or 200 μM) dose-dependently decreased the ox-LDL-induced up-regulation of the expression of ICAM-1 and P-selectin, and the enhanced adhesion and transmigration of monocytes. To determine the role of ROS/p38MAPK/NF-κB pathway, intracellular ROS level, p38MAPK protein expression, NF-κB transcription activity and protein expression, IκB-α degradation, NADPH oxidase subunit (Nox2 and p22phox) protein, and mRNA expression were measured. The results showed that delphinidin attenuated ox-LDL-induced generation of ROS, p38MAPK protein expression, NF-κB transcription activity and protein expression, IκB-α degradation, NADPH oxidase subunit (Nox2 and p22phox) protein and mRNA expression in endothelial cells in a dose-dependent manner. These results suggest that delphinidin attenuates ox-LDL induced expression of adhesion molecules (P-selectin and ICAM-1) and the adhesion of monocytes to endothelial cells by inhibiting ROS/p38MAPK/NF-κB pathway. These findings provide a basis for the design of potent antiatherosclerotic agents that will have therapeutic potential in the prevention of AS.

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.
