Abstract

20-Hydroxyecdysone, which is found in the rhizomes, roots and the stems of many plants, is an ecdysteroid hormone that regulates molting in insects. We have previously shown that 20-Hydroxyecdysone could alleviate neurological deficits induced by subarachnoid hemorrhage in rabbits. Thus, we hypothesized that 20-Hydroxyecdysone might protect neurons against hypoxic-ischemic injury. In present study, the effects of 20-Hydroxyecdysone on cobalt chloride (CoCl(2))-induced cellular injury in PC12 cells was investigated. The incubation of PC12 cells with CoCl(2) reduced the cell viability, increased the rate of apoptosis. However, when cells were treated with 20-Hydroxyecdysone before or after CoCl(2) exposure, the CoCl(2)-induced cellular injuries were significantly ameliorated. In addition, 20-Hydroxyecdysone dramatically reduced the CoCl(2)-induced production of reactive oxygen species (ROS), decreased the depolarization of the mitochondrial membrane, inhibited the release of cytochrome c into the cytosol and increased the Bax/Bcl-2 ratio. Furthermore, 20-Hydroxyecdysone eliminated the CoCl(2)-induced activation of caspase-3. Taken together, these results indicate that 20-Hydroxyecdysone may protect PC12 cells against CoCl(2)-induced cell injury by inhibiting ROS production and modulating components of the mitochondrial apoptosis pathway. Based on our results, 20-Hydroxyecdysone may be a potential candidate for intervention in hypoxic-ischemic brain injuries such as stroke.

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.
