Abstract

Protein therapy offers promising prospects for the treatment of various important diseases, thus it is highly desirable to develop a robust carrier that can deliver active proteins into cells. The development of a novel protein delivery platform based on the self‐assembly of multiarmed amphiphilic cyclodextrins (CDEH) is reported. CDEH can self‐assemble into nanoparticles in aqueous solution and achieve superior encapsulation of protein (loading capacity > 30% w/w) simply by mixing with protein solution without introducing any subsequent cumbersome steps that may inactivate proteins. More importantly, CDEH nanovehicles can be easily further modified with various targeting groups based on host–guest complexation. Using saporin as a therapeutic protein, AS1411‐aptamer‐modified CDEH nanovehicles can preferentially accumulate in tumors and efficiently inhibit tumor growth in a MDA‐MB‐231 xenograft mouse model. Moreover, folate‐targeted CDEH nanovehicles can also deliver Cas9 protein and Plk1‐targeting sgRNA into Hela cells, leading to 47.1% gene deletion and 64.1% Plk1 protein reduction in HeLa tumor tissue, thereby effectively suppressing the tumor progression. All these results indicate the potential of targeted CDEH nanovehicles in intracellular protein delivery for improving protein therapeutics.

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.
