March "], "item_description" : "The goal of gene transfer is protein expression. a process brought about by the insertion of a gene coding for a foreign protein into target cells resulting in the synthesis of the foreign protein For gene therapy, a tmnsferred therapeutic gene must be expressed at a level beneficial for the patient. This chapter provides an introductory overview of the rapidly evolving field of non-viral approaches for gene delivery to rnarnrnalian cells. Although currently there are fewer ongoing clinical trials using non-viral approaches than those using viral based systems, the number of non-viral trials is increasing. The long range goal of some research groups is the development of a genetically engineered artificial virus targeted to specific cells in the human body. An arurual conference, organized by Cambridge Healthtech Institute entitled Artificial Self-Assembling Systems for Gene Transfer, brings together researchers interested in this field1]. Assembly of an artificial virus is very complex; other research groups aim to develop simpler delivery systems consisting of a plasmid combined with delivery agents. Viral-based systems are very successful for gene delivery, but despite their successes, viral-based systems have some geneml limitations and system-specific limitations. When employing a viml-based system, the following limitations should be considered: - size limitation of the inserted gene due to packaging constraints (e. g. adenovirus, retrovirus) . - potential tumorigenesis (e. g. retrovirus) - potential for insertional mutagenesis (greater than plasmid based systems) - potential imrnunogenicity (e. g.", "item_img_path" : "https://covers4.booksamillion.com/covers/bam/1/46/137/881/1461378818_b.jpg", "price_data" : { "retail_price" : "219.99", "online_price" : "219.99", "our_price" : "219.99", "club_price" : "219.99", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
