Enhancing the therapeutic effect via elimination of hepatocellular carcinoma stem cells using Bmi1 siRNA delivered by cationic cisplatin nanocapsules
Publication date: Available online 26 May 2018Source: Nanomedicine: Nanotechnology, Biology and MedicineAuthor(s): Tan Yang, Yuyuan Chen, Pengxuan Zhao, Huiying Xue, Jia You, Bin Li, Yong Liu, Chuanchuan He, Xiaojuan Zhang, Lingling Fan, Robert J. Lee, Lei Li, Xiang Ma, Chuanrui Xu, Guangya XiangResistance of hepatocellular carcinoma (HCC) to systemic chemotherapy is partially due to presence of drug-resistant cancer stem cells. Bmi1 protein is essential for survival and proliferation of HCC cancer stem cells (CSCs). Here, we report that Bmi1 siRNA (Bmi1siR) loaded in cationic nanocapsules of cisplatin (NPC) eliminated ste...

Liposome-polyethylenimine complexes (DPPC-PEI lipopolyplexes) for therapeutic siRNA delivery in vivo
Publication date: Available online 20 August 2016 Source:Nanomedicine: Nanotechnology, Biology and Medicine Author(s): Alexander Ewe, Omkar Panchal, Shashank Reddy Pinnapireddy, Udo Bakowsky, Susanne Przybylski, Achim Temme, Achim Aigner Therapeutic applications of RNA interference (RNAi) require efficient siRNA delivery strategies in vivo. Combining lipid-based carriers with polymeric nanoparticles offers the favourable properties of both systems. This is the first study to explore polyethylenimine-based lipopolyplexes comprising a low-molecular weight PEI and the phospholipid DPPC for therapeutic siRNA use. Lipopolyplex...

ROS-Induced Nanotherapeutic Approach for Ovarian Cancer Treatment Based on the Combinatorial Effect of Photodynamic Therapy and DJ-1 Gene Suppression
This study represents a novel approach for intraoperative ovarian cancer treatment based on the combinatorial effect of a targeted photodynamic therapy (PDT) associated with suppression of the DJ-1 protein, one of the key players in the ROS defense of cancer cells. To assess the potential of the developed therapy, dendrimer-based nanoplatforms for cancer-targeted delivery of near-infrared photosensitizer, phthalocyanine, and DJ-1 siRNA have been constructed. In vitro studies revealed that therapeutic efficacy of the combinatorial approach was enhanced when compared to PDT alone and this enhancement was more pronounced in o...
