Folate receptor-targeted RNAi nanoparticles for silencing STAT3 in tumor-associated macrophages and tumor cells
Publication date: Available online 18 February 2020Source: Nanomedicine: Nanotechnology, Biology and MedicineAuthor(s): Jing Chen, Yushun Dou, Yue Tang, Xinru ZhangAbstractWe developed a STAT3 silencing siRNA to both tumor cells and M2 macrophages. The dual-targeting system prepared by electronic self-assembly was composed of folic acid-conjugated carboxymethyl chitosan for targeting and cationic chitosan derivatives for siRNA package. The effects of siRNA delivery was investigated in M2 macropahges and Lewis lung cancer cells(LLC). Due to the enhanced delivery efficiency, the dual-targeting delivery system exhibited a hig...

Silencing AXL by covalent siRNA-gelatin-antibody nanoconjugate inactivates mTOR/EMT pathway and stimulates p53 for TKI sensitization in NSCLC
Publication date: Available online 12 May 2019Source: Nanomedicine: Nanotechnology, Biology and MedicineAuthor(s): Dhananjay Suresh, Ajit Zambre, Soumavo Mukherjee, Shreya Ghoshdastidar, Yuexu Jiang, Trupti Joshi, Anandhi Upendran, Raghuraman KannanAbstractNon-small cell lung cancer (NSCLC) is the leading cause of cancer mortality with the 5-year survival rate remains a dismal 16% for the past 40 years. Drug resistance is a major obstacle to achieving long-term patient survival. Identifying and validating molecular biomarkers responsible for resistance and thereby adopting multi-directional therapy is necessary to imp...

Chemo-biologic combinatorial drug delivery using folate receptor-targeted dendrimer nanoparticles for lung cancer treatment
Publication date: Available online 16 November 2017 Source:Nanomedicine: Nanotechnology, Biology and Medicine Author(s): Narsireddy Amreddy, Anish Babu, Janani Panneerselvam, Akhil Srivastava, Ranganayaki Muralidharan, Allshine Chen, Yan D. Zhao, Anupama Munshi, Rajagopal Ramesh Co-administration of functionally distinct anti-cancer agents has emerged as an efficient strategy in lung cancer treatment. However, a specially designed drug delivery system is required to co-encapsulate functionally different agents, such as a combination of siRNA and chemotherapy, for targeted delivery. We developed a folic acid (FA) -conjugat...
