Furthermore, HPAA-PEG was produced by PEGylation, and then the aptamer targeted to prostate-specific membrane antigen (PSMA) was conjugated to the HPAA-PEG. The obtained HPAA-PEG-APT could form nanocomplexes with miRNA-133a-3p through electrostatic adsorption.Results: The results of immunocytochemistry indicated that the complexes could target PSMA-expressing LNCaP cells. The ability of HPAA-PEG-APT to facilitate the delivery of miRNA-133a-3p into LNCaP cells was proven, and HPAA-PEG-APT/miRNA-133a-3p demonstrated enhanced antitumor activity, lower cytotoxicity and better biocompatibility in vitro. Moreover, in a mouse tibial injection tumor model, the intravenous injection of the HPAA-PEG-APT/miRNA-133a-3p complex significantly inhibited cancer growth and extended the survival time.Conclusion: This study provided an aptamer-anchored HPAA-loaded gene system to deliver miRNA-133a-3p for better therapeutic efficacy of bone metastasis of prostate cancer.Keywords: miRNA, aptamer, hyperbranched polyamide amine, bone metastasis, prostate cancerYe YZhang LDai YWang ZLi CPeng YMa DHe PDove Medical Pressarticlemirnaaptamerhyperbranched polyamide aminebone metastasisprostate cancerMedicine (General)R5-920ENInternational Journal of Nanomedicine, Vol Volume 15, Pp 7173-7184 (2020)
