Available in PDF, EPUB and Kindle. Book excerpt: Recent years have witnessed an explosion of activity in the field of gene therapy. Following advances in our understanding of the molecular basis of disease, hopes are high that the tremendous potential market for drugs employing antisense nucleotides and genes will one day be fulfilled. However, many obstacles remain, not least problems in the technology of gene delivery systems. Much of today's research focuses on non-viral approaches to gene delivery. Of particular importance are supramolecular complexes formed between DNA and various natural and synthetic polymers and lipids, otherwise known as 'self-assembling complexes for gene delivery'. In view of this fact, the editors of this volume have assembled an international team of contributors to present up-to-date reviews of the major chemical, biological and clinical aspects of such gene delivery vectors. Reflecting the diversity of research in this field, this book comprehensively covers: * the principles of self-assembly * natural mechanisms for gene delivery to cells * cationic lipids and liposomes * polyelectrolyte DNA complexes * systemic biodistribution of drug delivery systems * targeting of conjugates for gene delivery * new approaches to gene delivery * clinical evaluation Self-assembling Complexes for Gene Delivery is an essential reference for all professionals with an interest in gene and antisense therapy or novel drug delivery systems, including medicinal and pharmaceutical chemists, clinicians, human geneticists, molecular biologists and pharmacologists.

Available in PDF, EPUB and Kindle. Book excerpt: DNA delivery into cells is a rapidly developing area in gene therapy and biotechnology. Moreover, it is a powerful research tool to determine gene structure, regulation, and function. Viral methods of DNA delivery are well-characterized and efficient, but little is known about the toxicity and immunogenecity of viral vectors. As a result, non-viral, transfection methods of DNA delivery are of increasing interest. Synthetic DNA Delivery Systems is a comprehensive and current resource on DNA transfection. The use of histidine-rich peptides and polypeptides as DNA delivery systems and self-assembled delivery systems based on cationic lipids and polymers are discussed. Targeted delivery to organelles, tumor cells and dendritic cells comprise an important topic.

Book excerpt: Nature has evolved sequence-controlled polymers, such as DNA and proteins, over its long history. The recent progress of synthetic chemistry, DNA recombinant technology, and computational science, as well as the elucidation of molecular mechanisms in biological processes, drive us to design ingenious polymers that are inspired by naturally occurring polymers, but surpass them in specialized functions. The term “designer biopolymers” refers to polymers which consist of biological building units, such as nucleotides, amino acids, and monosaccharides, in a sequence-controlled manner. This book particularly focuses on the self-assembling aspect of designer biopolymers. Self-assembly is one common feature in biopolymers that is used to realize their dynamic biological activities and is strictly controlled by the sequence of biopolymers. In a broad sense, the self-assembly of biopolymers includes a double-helix formation of DNA, protein folding, and higher-order protein assembly (e.g., viral capsids). Designer biopolymers are now going beyond what nature evolved: researchers have generated DNA origami, protein cages, peptide nanofibers, and gels. This book illustrates the latest interdisciplinary work on self-assembling designer biopolymers. As shown by this book, the self-assembly of biopolymers has a great impact on a variety of research fields, including molecular biology, neurodegenerative diseases, drug delivery, gene therapy, regenerative medicine, and biomineralization. Designer biopolymers will help researchers to better understand biological processes, as well as to create innovative molecular systems. We believe that this book will provide readers with new ideas for their molecular design strategies for frontier research.

Available in PDF, EPUB and Kindle. Book excerpt: The success in gene therapy relies strongly on new efficient gene delivery vectors. Non-viral vectors are highly attractive, since they can deliver large quantities of genetic information and are low immunogenic. In this respect, unsymmetrical bolaamphiphiles (bolas) bearing two different hydrophilic head-groups connected by a hydrophobic spacer could be an attractive alternative for vector design, as they can form well-defined supramolecular nanostructures (nanovesicles and nanotubes) that are more stable than those formed with lipids. The aim of the present work was to develop new gene delivery vectors based on bolas capable to form such nanostructures hosting a DNA molecule and exposing at their external surface neutral ligands. For this purpose, a variety of bolas, bearing cationic and neutral groups connected by a hydrophobic spacer, were obtained by multi-step organic synthesis. Their characterization by different instrumental techniques suggested that the nature of the head groups as well as the hydrophobic spacer defines the bola self-assembly, their interaction with DNA and the morphology of their complexes (bolaplexes). While the first two generations of bolas lack the essential features of nonviral vectors, the final third generation was found highly promising. The latter showed a strong interaction with DNA, the formation of small bolaplexes and good transfection efficiency in different cell lines. The increase in transfection efficiency in presence of DOPE or chloroquine suggested that the key barrier for their internalization could be the lipid fusion and the endosomal escape. Some bolaplex formulations showed a transfection efficiency comparable to the best commercial transfection agents. Thus, the present work introduces a new class of efficient transfection agents based on unsymmetrical bolaamphiphiles.

This book was released on 2010 with total page 614 pages. Available in PDF, EPUB and Kindle. Book excerpt: We report on the gene silencing activities of Cationic Liposome (CL)-siRNA complexes transfected into cultured mammalian cells. We show that traditional CL formulations are inefficient delivery vectors for siRNA, requiring much larger CL:NA charge ratios for measurable activity. The high amount of CL required to achieve these charge ratios induces cellular toxicity, however, complex formulations with multivalent (5+) CLs can alleviate this effect. Additionally, we present new structural data suggesting that the internal organization of the siRNA within the complex is isotropic and not optimally packed. Poor packing negatively influences the stability of the complex and is related to the lower delivery efficiencies. Synchrotron x-ray diffraction experiments on model CL-short DNA complexes revealed that end stacking of the duplexes will promote a novel, highly ordered centered rectangular phase of DNA within the complex - in contrast to the unorganized siRNA. Furthermore, in systems designed to inhibit end stacking, the organization became dependent on the shape anisotropy of the NA, favoring longer sequences over shorter sequences. Taken together, we suggest some criteria for CL-short NA formulations that improve their overall stability and build towards more efficient CL-siRNA complexes for gene silencing.

Shirazi and published by . This book was released on 2012 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: Environmentally responsive materials, i.e., materials that are designed to react to changes in their environment with a modification in their properties or structure, draw growing interests especially for synthetic materials for gene therapy and biomaterials applications. In this work, environmentally responsive lipid materials are designed to be responsive to (i) reducing milieu of the cytoplasm and (ii) low pH of late endosome. (i) The cleavable multivalent lipids (CMVLs) are designed with a disulfide bond in the linker between cationic headgroup and hydrophobic tails. CMVLs are designed to show the effect of lipid-nucleic acid complexes degradation in cytoplasm on nucleic acid delivery and cytotoxicity (ii) An acid-labile PEG-lipid (HPEG2K-lipid) capable of losing PEG chains at the pH of late endosomes is tailored for optimum circulation lifetime of liposomes as well as efficient endosomal release. Here, the efficient synthesis is presented as well as extensive characterization of the series of tailored cleavable multivalent lipids (CMVLn, with n = 2 to 5 the number of positive headgroup charges at full protonation). The self-assembled complexes of the CMVLs and DNA are a prototypical environmentally responsive material, undergoing extensive structural rearrangement when exposed to reducing agents. CMVL-DNA complexes are employed as carriers for nucleic acids in DNA transfection as well as small interfering RNA silencing experiments. The employment of CMVLs in complexes with nucleic acids presents the effect of CMVLs degradation on cytotoxicity, DNA transfection as well as siRNA silencing efficiency. The investigation of structural evolution of CMVL-DNA complexes at varied complex composition, temperature and incubation time was assessed employing small-angle X-ray scattering (SAXS) and wide-angle X-ray scattering (WAXS).
