    Peptide nucleic acid (PNA) analogues of DNA have attracted interest as potential pharmacological regulators of gene expression since they have the capacity to invade duplex DNA forming Watson−Crick base paired PNA:DNA heteroduplexes. Unfortunately, strand invasion is limited to homopurine and homopyrimidine sequences and there is the need to explore further PNA analogues for the purpose of. Progress has been made in the development of different types of nucleic acids such as DNA and siRNA with the potential to form the basis of new treatments for genetic and acquired disorders. The lack of suitable vectors for the delivery of nucleic acids, however, represents a major hurdle to their continued development and therapeutic application.

    Gene design and splicing efficiency analysis of artificial rbcS2i1 insertion sites in the shble coding sequence represented by the transformation efficiency of C. reinhardtii.(A) Antibiotic selection cassette adopted from the pOptimized vector toolkit containing the shble gene and an N-terminal linker which includes an additional SmaI restriction enzyme cleavage site and a representative TAP. Abstract: Improving the performance of non-viral gene-delivery vehicles that consist of synthetic compounds and nucleic acids is a key to successful gene therapy. Supplementing synthetic vehicles with various biological functions by using natural or artificial peptides is a promising approach with which to achieve this goal.

    Solid Phase Peptide Synthesis (SPPS) The control and regulatory mechanisms for many biological processes are dependent on peptides and proteins derived from α–amino acids. In addition, many modern medicines are now produced from peptides or derivatives of peptides. Bridged nucleic acids (BNAs) are artificial bicyclic oligonucleotides that contain a five-membered or six-membered bridged structure with a “fixed” C3’-endo sugar puckering (Saenger ). The bridge is synthetically incorporated at the 2’, 4’-position of the ribose to afford a 2’, 4’-BNA monomer.

Synthetic nucleic acids as inhibitors of gene expression: mechanisms, applications, and therapeutics implications. [Levon Khachigian;] -- "This book brings together timely, authoritative reviews by renowned international leaders in the fields of ribozymes, RNA interference, DNAzymes and oligonucleotide decoys, with emphasis on.

Synthetic nucleic acids as inhibitors of gene expression: mechanisms, applications, and therapeutics implications. Synthetic nucleic acids are at the cutting-edge of molecular strategies that target genes of interest in a specific, efficient and cost-effective manner.

These tools are now used as gene-silencing agents in vitro and as novel therapeutics in human disease. This book brings together reviews by leaders in the fields of ribozymes, RNA interference.

Other chapters provide a critical assessment of eukaryotic nucleic acid polymerases. This book discusses as well some examples from plant mitochondrial systems. The final chapter deals with two special areas of plant biology where the expression of the nucleic acids is seen in striking relief, the formation of plant tumors, and the growth and.

In this study, S. pyogenes growth was inhibited by application of peptide-conjugated antisense-peptide nucleic acids (PNAs) specific for the essential gyrase A gene (gyrA). Thereby, HIV-1 Tat peptide-coupled PNAs were more efficient inhibitors of streptococcal growth as compared with (KFF)3K-coupled PNAs.

Antisense oligonucleotides and short interfering RNAs (siRNAs) are nucleic acids-targeting reagents for gene expression modulation that are being developed as drugs for many applications.

A number of useful synthetic nucleic acids analogues have been introduced recently to greatly improve their properties for use as therapeutics. While Streptococcus pyogenes is consistently susceptible toward penicillin, therapeutic failure of penicillin treatment has been reported repeatedly and a considerable number of patients exhibit allergic reactions to this substance.

At the same time, streptococcal resistance to alternative antibiotics, e.g., macrolides, has increased. Taken together, these facts demand the development of novel. DNA, the fundamental genetic polymer of all living organisms on Earth, can be chemically modified to embrace novel functions that do not exist in nature.

The key chemical and structural parameters for genetic information storage, heredity, and evolution have been elucidated, and many xenobiotic nucleic acids (XNAs) with non-canonical structures are developed as alternative genetic materials in.

A milestone for the origin of life was the onset of a sustained functional interplay between nucleic acids, peptides, lipids and sugars, to form chemical dynamic off-equilibrium systems.

Nucleic Acids Res – PubMed Google Scholar. Alternatively, the antisense nucleic acid can be produced biologically using an expression vector into which a nucleic acid has been subcloned in an antisense orientation (i.e., RNA transcribed from the inserted nucleic acid will be of an antisense orientation to a target nucleic acid of interest, described further in the following subsection).

Antisense oligonucleotides and short interfering RNAs (siR-NAs) are nucleic acids-targeting reagents for gene expression modulation that are being developed as drugs for many applications.

Keywords:gene expression, antisense oligonucleotides, dna mimetics, intercalators, photoreactive agents, antigene Abstract: Artificial control of gene expression has great potential in the treatment of many human diseases, and peptide nucleic acids (PNAs) offer several potential advantages for silencing gene expression in mammalian cells.

Among these nanomedicines, nanoparticle mediated delivery of nucleic acids has been put forward as key instrument to modulate gene expression, be it targeted gene silencing, interference RNA mechanisms and/or gene edition. These novel delivery systems have strongly relied on nanoparticles and, in particular, gold nanoparticles (AuNPs) have.
