{"doi":"10.17615/qpdc-8q89","title":"Improving Cancer Chemoradiotherapy Treatment by Dual Controlled Release of Wortmannin and Docetaxel in Polymeric Nanoparticles","abstract":"Combining molecularly targeted agents and chemotherapeutics is an emerging strategy in cancer treatment. We engineered sub-50 nm diameter diblock copolymer nanoparticles (NPs) that can sequentially release wortmannin (Wtmn, a cell signaling inhibitor) and docetaxel (Dtxl, genotoxic anticancer agent) to cancer cells. These NPs were studied in chemoradiotherapy, an important cancer treatment paradigm, in the preclinical setting. We demonstrated that Wtmn enhanced the therapeutic efficacy of Dtxl and increased the efficiency of radiotherapy (XRT) in H460 lung cancer and PC3 prostate cells in culture. Importantly, we showed that NPs containing both Wtmn and Dtxl release the drugs in a desirable sequential fashion to maximize therapeutic efficacy in comparison to administering each drug alone. An in vivo toxicity study in a murine model validated that NPs containing both Dtxl and Wtmn do not have a high toxicity profile. Lastly, we demonstrated that Dtxl/Wtmn-coencapsulated NPs are more efficient than each sin...","journal":"UNC Libraries","year":2020,"id":144557,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":0,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9563,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2020-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":277903,"name":"Kin Man Au","orcid":"0000-0001-9341-0479","position":1,"is_corresponding":false},{"id":613642,"name":"Virginia Perello","orcid":null,"position":2,"is_corresponding":false},{"id":609906,"name":"Xi Tian","orcid":"0000-0002-9401-685X","position":3,"is_corresponding":false},{"id":407720,"name":"Yuanzeng Min","orcid":"0000-0001-5030-0210","position":4,"is_corresponding":false},{"id":407721,"name":"Joseph M.
