Abstract

Objectives The aim of the present study is to investigate the effects of sonodynamic action of hypocrellin B on human breast cancer cells and further explore its underlying mechanisms. Methods The cell viability of breast cancer MDA-MB-231 cells was examined by 3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyl tetrazolium bromide (MTT) assay. Alterations on cell apoptosis, intracellular reactive oxygen species generation (ROS), mitochondrial membrane potential, and DNA fragmentation was analyzed by flow cytometer. The subcellular localization of hypocrellin B was assessed by a confocal laser scanning microscope. Mitochondria damage and nuclear morphological changes were observed under a fluorescence microscope. To further explore whether caspase pathway was involved in cell apoptotic induction of sonodynamic action of hypocrellin B, the pan-caspase inhibitor Z-Val-Ala-DL-Asp (ome)-Fluoromethylketone (z-VAD-fmk) was added to the cells one hour prior to loading the sonosensitizer, and then cell viability and apoptosis were analyzed after hypocrellin B treatment. Results Sonodynamic treatment of hypocrellin B HB significantly suppressed cell viability of MDA-MB-231 cells. Sonodynamic action of hypocrellin B caused excessive ROS accumulation, mitochondrial dysfunction, cell apoptosis, DNA fragmentation and nuclear morphological damage. Moreover, the cytotoxicity and cell apoptosis induced by sonodynamic action of hypocrellin B were remarkably rescued by the caspase spectrum inhibitor z-VAD-fmk. Conclusions These results demonstrated that hypocrellin B had significant sonodynamic killing and apoptotic induction effect on breast cancer cells. And cell apoptosis induced by sonodynamic action of hypocrellin B was partly dependent on caspase pathway.

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.
