Abstract

Ceramides derived from sphingosine contribute to the apoptotic processes of neuronal cells in neurodegenerative disorders including Alzheimer's disease. This study investigates the potential neuroprotective effects of Asiatic acid, a triterpenoid derived from Centella asiatica, against C(2)-ceramides-induced cell death in primary cultured rat cortical neuronal cells. In primary neurons, Asiatic acid (0.01 to 1.0 μmol/l) reduced C(2)-ceramide-induced cell death and mitochondria membrane potential loss in a concentration-dependent manner. Furthermore, Asiatic acid decreased cellular production of reactive oxygen species following C(2)-ceramide treatment. At a maximal concentration of 1.0 μmol/l, Asiatic acid partly counteracted the pro-apoptotic effects of the C(2)-ceramide by reducing the cytosolic release of HtrA2/Omi, the upregulation of Bax and caspase 3, as well as the dephosphorlyation of ERK1/2. Taken together, these data suggest that Asiatic acid protects neurons from C(2)-ceramide-induced cell death by antagonizing mitochondria-dependent apoptosis.

Recomputing p-values needs the paper’s full text.

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?

  • In vitro studies show CAW whole extract and isolated compounds facilitate neurite outgrowth and elicit neuroprotection.

    “Previously, in vitro studies have shown that both CAW whole extract and isolated compounds (detailed in a review [32]) facilitate neurite outgrowth [6,28,106], and elicit neuroprotection [107,108,109,110,111].”

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.
