Download or read book How Free Cationic Polymer Chains Promote Gene Transfection written by Yue Yanan and published by Springer Science & Business Media. This book was released on 2013-05-13 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this PhD thesis, Yue Yanan addresses a long-overlooked and critical question in the development of non-viral vectors for gene delivery. The author determines that those uncomplexed and cationic polymer chains free in the solution mixture of polymer and DNA facilitate and promote gene transfection. Furthermore, by using a combination of synthetic chemistry, polymer physics and molecular biology, Yue confirms that it is those cationic polymer chains free in the solution mixture, rather than those bound to DNA chains, that play a decisive role in intracellular trafficking. Instead of the previously proposed and widely accepted “proton sponge” model, the author's group propose a new hypothesis based on the results of several well-designed and decisive experiments. These results show that free polycationic chains with a length of more than ~10 nm are able to partially block the fusion between different endocytic vesicles, including the endocytic-vesicle-to-endolysosome pathway. This thesis is highly original and its results greatly deepen our understanding of polymer-mediated gene transfection. More importantly, it provides new insights into the rational design of next-generation superior polymeric gene-delivery vectors.

Available in PDF, EPUB and Kindle. Book excerpt: The series Topics in Current Chemistry Collections presents critical reviews from the journal Topics in Current Chemistry organized in topical volumes. The scope of coverage is all areas of chemical science including the interfaces with related disciplines such as biology, medicine and materials science. The goal of each thematic volume is to give the non-specialist reader, whether in academia or industry, a comprehensive insight into an area where new research is emerging which is of interest to a larger scientific audience. Each review within the volume critically surveys one aspect of that topic and places it within the context of the volume as a whole. The most significant developments of the last 5 to 10 years are presented using selected examples to illustrate the principles discussed. The coverage is not intended to be an exhaustive summary of the field or include large quantities of data, but should rather be conceptual, concentrating on the methodological thinking that will allow the non-specialist reader to understand the information presented. Contributions also offer an outlook on potential future developments in the field.

Download or read book Polymers and Nanomaterials for Gene Therapy written by Ravin Narain and published by Woodhead Publishing. This book was released on 2016-01-09 with total page 303 pages. Available in PDF, EPUB and Kindle. Book excerpt: Polymers and Nanomaterials for Gene Therapy provides the latest information on gene therapy, a topic that has attracted significant attention over the past two decades for the treatment of inherited and acquired genetic diseases. Major research efforts are currently focused on designing suitable carrier vectors that compact and protect oligonucleotides for gene therapy. The book explores the most recent developments in the field of polymer science and nanotechnology, and how these advancements have helped in the design of advanced materials. Non-viral vector systems, including cationic lipids, polymers, dendrimers, peptides and nanoparticles, are potential routes for compacting DNA for systemic delivery. However, unlike viral analogues that have no difficulty in overcoming cellular barriers and immune defense mechanisms, non-viral gene carriers consistently exhibit significant reduced transfection efficiency due to numerous extra- and intracellular obstacles. Therefore, biocompatibility and potential for large-scale production make these compounds increasingly attractive for gene therapy. This book contains chapters on the engineering of polymers and nanomaterials for gene therapy, and how they can form complexes with DNA and avoid both in vitro and in vivo barriers. Other chapters describe in vitro, ex vivo, in vivo gene therapy studies, and the current issues affecting non-viral gene therapy. - Explores current challenges in the research of genetic diseases - Discusses polymers for gene therapy and their function in designing advanced materials - Provides examples of organic and inorganic nanomaterials for gene therapy - Includes labeling, targeting, and assays - Looks at characterization, physico-(bio)chemical properties, and applications

Download or read book Community Series in the Role of Angiogenesis and Immune Response in Tumor Microenvironment of Solid Tumor volume II written by Xi Cheng and published by Frontiers Media SA. This book was released on 2023-12-13 with total page 213 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Research Topic is the second volume of the “Community Series in the Role of Angiogenesis and Immune Response in Tumor Microenvironment of Solid Tumor". Please Volume I here. The microenvironment of tumors is consisted of the tumor stroma, proliferating tumor cells, infiltrating inflammatory cells, blood vessels, and various associated tissue cells. The pre-metastatic niche (PRN) is described as supportive and receptive, which undergoes cellular and molecular changes to form the fertile “soil” or metastatic-designated sites for metastatic tumor cell “seed” colonization. Thus, the PRN supports promoting tumor metastasis and tumor settlement in distant organs. The infiltration of the immune cells and the formation of blood vessels from the pre-metastatic sites are critical for the tumor microenvironment. Typically, the angiogenic factor is strongly associated with the inflammatory response during the development of tumors. Additionally, the immunoediting processes are essentially devoted to promoting angiogenesis and modulating the innate and specific immune responses.
