The resistance of tumor cells is a major cause of chemotherapy failure in cancer patients. Photodynamic therapy (PDT) as a noninvasive treatment strategy with high specificity is a promising method for the treatment of cancer. In this study, a CD44 and N-cadherin dual targeting drug delivery system in combination with mesoporous titanium dioxide nanoparticle (MTN)-based PDT has been successfully constructed for overcoming drug resistance. Hyaluronic acid (HA) and ADH-1 (a cyclic pentapeptide) were grafted onto the surface of MTN to construct ADH-1-HA-MTN, and doxorubicin (DOX) was selected as a model drug. HA can both trap DOX in the wells of MTN and target CD44-overexpressing tumor cells. ADH-1 blocks the EMT process of tumor cells by selectively inhibiting the function of N-cadherin. Besides, a large number of reactive oxygen species (ROS) were generated by MTN under X-ray irradiation, which could provide a cancer cell killing effect. Cytotoxicity tests showed that ADH-1-HA-MTN/DOX was more toxic to tumor cells than its non-ADH-1 modified counterparts. Western blotting analysis showed that ADH-1-HA-MTN/DOX overcame the drug resistance of tumor cells by preventing the process of epithelial–mesenchymal transition. Taken together, ADH-1-HA-MTN may be a promising targeted drug delivery system to overcome the drug resistance of tumors.

Journal of Materials Chemistry B

Journal of Materials Chemistry A, B & C cover high quality studies across all fields of materials chemistry. The journals focus on those theoretical or experimental studies that report new understanding, applications, properties and synthesis of materials. The journals have a strong history of publishing quality reports of interest to interdisciplinary communities and providing an efficient and rigorous service through peer review and publication. The journals are led by an international team of Editors-in-Chief and Associate Editors who are all active researchers in their fields. Journal of Materials Chemistry A, B & C are separated by the intended application of the material studied. Broadly, applications in energy and sustainability are of interest to Journal of Materials Chemistry A, applications in biology and medicine are of interest to Journal of Materials Chemistry B, and applications in optical, magnetic and electronic devices are of interest to Journal of Materials Chemistry C. More than one Journal of Materials Chemistry journal may be suitable for certain fields and researchers are encouraged to submit their paper to the journal that they feel best fits for their particular article. Example topic areas within the scope of Journal of Materials Chemistry B are listed below. This list is neither exhaustive nor exclusive. Antifouling coatings Biocompatible materials Bioelectronics Bioimaging Biomimetics Biomineralisation Bionics Biosensors Diagnostics Drug delivery Gene delivery Immunobiology Nanomedicine Regenerative medicine & Tissue engineering Scaffolds Soft robotics Stem cells Therapeutic devices image block All articles published in Journal of Materials Chemistry B from 2019 onwards will be indexed in MEDLINE®.
