Nucleic acids participate in a large number of biological processes. However, current approaches for small molecules targeting protein are incompatible with nucleic acids. On the other hand, the lack of crystallization of nucleic acid is the limiting factor for nucleic acid drug design. Because of the improvements in crystallization in recent years, a great many structures of nucleic acids have...

Nucleic acids are an important class of biological macromolecules that carry out a variety of cellular roles. For many functions, naturally occurring DNA and RNA molecules need to fold into precise three-dimensional structures. Due to their self-assembling characteristics, nucleic acids have also been widely studied in the field of nanotechnology, and a diverse range of intricate three-dimensio...

Extracellular vesicles (EVs), as natural carriers, are regarded a new star in nanomedicine due to their excellent biocompatibility, fascinating physicochemical properties, and unique biological regulatory functions. However, there still some challenges using EVs, including poor targeting ability the clearance from circulation, which may limit further development clinical use. Nucleic acid has f...

Thermodynamic features related to preparation and use of self-assemblies formed between multilamellar and unilamellar zwitterionic liposomes and polynucleotides with various conformation and sizes are presented. The divalent metal cation or surfactant-induced adsorption, aggregation and adhesion between single- and double-stranded polyribonucleotides and phosphatidylcholine vesicles was followe...

Protein-nucleic acid interaction plays an essential role in the regulation of gene expression. Structural and binding information provides insight into the mechanism of protein-nucleic acid recognition. Although there are structural databases for protein-nucleic acid complexes, there exists no database for protein-nucleic acid binding. Thus, we have decided to develop the Thermodynamic Database...

Cationic liposome-nucleic acid complexes, which were originally developed for use as non-viral gene delivery vectors, may now have an equally important application as immunotherapeutic drugs. Recent studies have highlighted the ability of cationic liposomes to potently activate the innate immune system when used to deliver certain Toll-like receptor (TLR) agonists. The immune-enhancing properti...

MOTIVATION There are many important proteins which bind single-stranded nucleic acids, such as the nucleocapsid protein in HIV and the RecA DNA repair protein in bacteria. The presence of such proteins can strongly alter the secondary structure of the nucleic acid molecules. Therefore, accurate modeling of the interaction between single-stranded nucleic acids and such proteins is essential to f...

Nucleic acid detection in hematological disorders has been carried out in a wide range of medical fields or departments. Hence, it is recommended that the hematology laboratory should draw up guidelines or a manual for each disease (group), field or specialty. Nucleic acid detection is defined as processes which are disclosed using depolymerization of a nucleic acid hybrid (deoxyribonucleic aci...
