Abstract

Autophagy was considered as a double-edged sword that might cooperate, aggravate, or antagonize apoptosis. We found that the sonodynamic therapy (SDT) in low dosage induced autophagy and might function as a survival pathway for breast cancer and exhibit resistance to SDT-mediated apoptosis. In this sense, it was highly desired to enhance SDT via autophagy regulation strategy. Herein, we reported a biomimetic nanoplatform based on hollow mesoporous titanium dioxide nanoparticles (HMTNPs) by autophagy inhibitor (hydroxychloroquine sulphate, HCQ) loading and cancer cell membrane (CCM) coating. Owing to the biomimetic surface functionalization, the CCM-HMTNPs/HCQ could escape from macrophage phagocytosis, actively recognize and home in on the tumor by homologous targeting ability. Afterward, the released HCQ in response to the ultrasound stimulus was capable of blocking the autophagic flux and cutting off the nutrients supply derived from the damaged organelles, which was anticipated to abrogate the cells' resistance to SDT. Meanwhile, the vessel normalization effect of HCQ alleviated the tumor hypoxia, which was bound to enhance the oxygen-dependent HMTNPs-mediated SDT treatment. Based on the above findings, it was undoubtedly logical that CCM-HMTNPs/HCQ would sensitize breast cancer cells to SDT via autophagy regulation strategy, which held a great promise in cancer treatment.

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.
