A Lipiodol Pickering Emulsion Stabilized by Iron-Doped Carbon Nanozymes for Liver Transarterial Chemoembolization.

Adv Sci (Weinh)

December 2024

Department of Interventional Center, Biomedical Innovation Center, The Sixth Affiliated Hospital, Sun Yat-Sen University, Guangzhou, 510655, P. R. China.

Transarterial chemoembolization (TACE) utilizing a water-in-oil lipiodol emulsion is a preferable therapeutic strategy for advanced liver cancer in clinical practice. However, the low stability of the lipiodol emulsion and poor efficacy of chemotherapeutic drug seriously undermine the efficiency of TACE. Herein, a novel lobaplatin-loaded lipiodol emulsion (denoted as ICN-LPE) is developed by constructing a lipiodol Pickering emulsion (LPE) stabilized with iron-doped carbon nanozymes (ICN) to mitigate the issue of lipiodol-water separation.

Department of General Surgery (Colorectal Surgery), The Sixth Affiliated Hospital, Sun Yat-sen University, Guangzhou, China.

Chemotherapy based on oxaliplatin (OXA) is the first-line treatment for advanced colorectal cancer (CRC), and acquired resistance to OXA is the main reason for clinical treatment failure in CRC. To search for compounds that can reverse OXA resistance, we screened a small molecule inhibitor drug library and identified a drug, Raddeanin A (RA), that enhanced the anticancer effect of OXA. Using human CRC cell lines, CRC organoid models, and subcutaneous tumorigenic studies, we determined that RA inhibits the proliferation of CRC cells by promoting apoptosis and inducing cell cycle arrest.
