Description | Dehydrotrametenolic acid (Dehydroeburicoic acid) induces necrotic cell death that involves Ca(2+) overload, mitochondrial dysfunction, and calpain activation in human glioblastomas. |
In vitro | 3-(4,5-Dimethyl-thiazol-2-yl)-2,5-diphenyltetrazolium bromide and lactate dehydrogenase release assays indicated that Dehydroeburicoic acid inhibited the proliferation of the human glioblastoma cell U87MG. In addition, Annexin V and propidium iodide staining showed that Dehydroeburicoic acid treatment led to a rapid increase of glioblastomas in the necrotic/late apoptotic fraction, whereas cell cycle analysis revealed that Dehydroeburicoic acid failed to significantly enhance the population of U87MG cells in the hypodiploid (sub-G1) fraction. Using electron microscopy, we found that Dehydroeburicoic acid induced significant cell enlargements, massive cytoplasmic vacuolization, and loss of mitochondrial membrane integrity. Dehydroeburicoic acid treatment triggered an intracellular Ca(2+) increase, and Dehydroeburicoic acid-induced cell death was significantly attenuated by BAPTA-AM but not ethylenediaminetetraacetic acid or ethylene glycol tetraacetic acid. Dehydroeburicoic acid instigated a reduction of both mitochondrial transmembrane potential and intracellular ATP level. Moreover, Dehydroeburicoic acid induced proteolysis of alpha-spectrin by calpain, and Dehydroeburicoic acid cytotoxicity in U87MG cells was caspase-independent but was effectively blocked by calpain inhibitor. Interestingly, Dehydroeburicoic acid also caused autophagic response that was prevented by calpain inhibitor. |
