Abstract

Chlorogenic acid (CGA) widely exists in edible and medicinal plants. We aimed to evaluate the effect of CGA on the protection from apoptosis by methylmercury (MeHg) in PC12 cells. Cell viability was evaluated by MTT assay. Apoptosis was assayed by flow cytometry detection. Caspase-3 activity was measured by confocal microscopy. Intracellular GSH levels were determined by bicinchoninic acid protein assay. Intracellular reactive oxygen species (ROS) was assessed by means of chloromethyl-dihydrodichlorofluorescein diacetate. Glutathione peroxidase (GPx) activity was determined by UV. In order to elucidate the action of CGA, the protective effects of CGA were compared to Vit.E. CGA was effective at protecting PC12 cells against MeHg-induced damage in dose-dependent manner. CGA not only suppressed the generation of ROS, the decrease of activity in GPx and the decrease of GSH, but also attenuated caspase-3 activation in PC12 cells by MeHg. CGA eventually protected PC12 cells against MeHg-induced apoptosis. The results highlighted that CGA may exert neuroprotective effects through its antioxidant actions.

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.
