Structural basis for the sequence-specific RNA-recognition mechanism of human CUG-BP1 RRM3 [PDF]

, 2009
The CUG-binding protein 1 (CUG-BP1) is a member of the CUG-BP1 and ETR-like factors (CELF) family or the Bruno-like family and is involved in the control of splicing, translation and mRNA degradation.

Bis-3-Chloropiperidines Targeting TAR RNA as A Novel Strategy to Impair the HIV-1 Nucleocapsid Protein

Molecules, 2021
Specific RNA sequences regulate functions essential to life. The Trans-Activation Response element (TAR) is an RNA stem–bulge–loop structure involved in several steps of HIV-1 replication.

Conformation of nucleic acids and the analysis of the hypochromic effect [PDF]

Biochemical Journal, 1970
The spectra of two double-helical RNA species isolated from virus-like particles found in the mycelium of Penicillium chrysogenum were measured at about 25 degrees C, and at 95 degrees C after denaturation to a single-stranded form, and compared with the spectrum of the equivalent mixture of nucleotides.

DNA and its counterions: A molecular dynamics study [PDF]

, 2004
The behaviour of mobile counterions, Na+ and K+, was analysed around a B-DNA double helix with the sequence CCATGCGCTGAC in aqueous solution during two 50 ns long molecular dynamics trajectories.

Original Synthesis of a Nucleolipid for Preparation of Vesicular Spherical Nucleic Acids

Nanomaterials, 2022
Spherical nucleic acids (SNAs)—nanostructures, consisting of a nanoparticle core densely functionalized with a shell of short oligonucleotide strands—are a rapidly emerging class of nanoparticle-based therapeutics with unique properties and specific ...

Identification of G-quadruplex DNA/RNA binders: Structure-based virtual screening and biophysical characterization [PDF]

, 2017
Background Recent findings demonstrated that, in mammalian cells, telomere DNA (Tel) is transcribed into telomeric repeat-containing RNA (TERRA), which is involved in fundamental biological processes, thus representing a promising anticancer target. For

The Many (Inter)faces of Anti-CRISPRs: Modulation of CRISPR-Cas Structure and Dynamics by Mechanistically Diverse Inhibitors

Biomolecules, 2023
The discovery of protein inhibitors of CRISPR-Cas systems, called anti-CRISPRs (Acrs), has enabled the development of highly controllable and precise CRISPR-Cas tools.

The epithelial barrier theory proposes a comprehensive explanation for the origins of allergic and other chronic noncommunicable diseases

FEBS Letters, EarlyView.
Exposure to common noxious agents (1), including allergens, pollutants, and micro‐nanoplastics, can cause epithelial barrier damage (2) in our body's protective linings. This may trigger an immune response to our microbiome (3). The epithelial barrier theory explains how this process can lead to chronic noncommunicable diseases (4) affecting organs ...

Formation of a Unique Cluster of G-Quadruplex Structures in the HIV-1 nef Coding Region: Implications for Antiviral Activity [PDF]

, 2013
G-quadruplexes are tetraplex structures of nucleic acids that can form in G-rich sequences. Their presence and functional role have been established in telomeres, oncogene promoters and coding regions of the human chromosome.

Features of “All LNA” Duplexes Showing a New Type of Nucleic Acid Geometry

Journal of Nucleic Acids, 2012
“Locked nucleic acids” (LNAs) belong to the backbone-modified nucleic acid family. The 2′-O,4′-C-methylene-β-D-ribofuranose nucleotides are used for single or multiple substitutions in RNA molecules and thereby introduce enhanced bio- and thermostability.
