New peptide nucleic acids for biotechnological applications [PDF]

, 2010
In the present study was designed and realized a new similar to the PNA. It is a chiral nucleo-γ-peptide, dabPNA, isomer of the aegPNA unit and characterized by a 2,4-diaminobutyric acid (DABA)-based backbone carrying the carboxymethylated nucleobase on ...

Atypical response regulator ChxR from Chlamydia trachomatis is structurally poised for DNA binding. [PDF]

PLoS ONE, 2014
ChxR is an atypical two-component signal transduction response regulator (RR) of the OmpR/PhoB subfamily encoded by the obligate intracellular bacterial pathogen Chlamydia trachomatis. Despite structural homology within both receiver and effector domains

Peripheral lysosomes recruit PLEKHG3 to focal adhesions and restrain protrusion dynamics

FEBS Letters, EarlyView.
Proximity‐dependent labeling at the LAMTOR complex revealed the Rho GEF PLEKHG3 as a lysosome‐proximal protein directing the study toward the influence of lysosome positioning on actin dynamics and cell motility. We show that PLEKHG3 colocalizes with lysosomes at focal adhesion sites and observe that forced peripheral dispersion of lysosomes hinders ...

Methylation Effects on Nucleic Acid Conformations [PDF]

, 1978
Chemical modification of nucleic acids by alkylating agents continues to be extensively explored from the perspective of chemical mutagenesis and carcinogenesis. Largely through the pioneering in vitro and in vivo studies of Lawley (1961), Lawley and Brookes (1963), Singer (1972), and Reese and coworkers (1965), coupled with theoretical predictions of ...

Inhibition of cyclin‐dependent kinases 12/13 using CT7439 as a treatment for colorectal cancer with CDK12 upregulation

Molecular Oncology, EarlyView.
The proposed mechanism of action for the CDK12/13 inhibitor and cyclin K degrader, CT7439. CDK12/13 inhibition interrupts transcription elongation, leading to increased DNA damage that results in cell death. This agent is a potentially novel treatment option for patients with colorectal cancer. Created in BioRender. Cyclin‐dependent kinase (CDK) 12 and

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.

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.

Cancer cell‐intrinsic type 1 interferon: production, signaling, and outcomes within sex‐biased, female malignancies

Molecular Oncology, EarlyView.
The cell‐autonomous roles of interferon type 1 vary based on duration and intensity. While acute, robust signaling results in cancer cell cytotoxic effects, sustained, low‐level signaling is associated with tumor‐promoting effects. This review summarizes current research of IFN‐1 in cancer and within the clinical setting, with an emphasis on female ...

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 ...

Electrostatics of Nucleic Acid Folding under Conformational Constraint [PDF]

Journal of the American Chemical Society, 2012
RNA folding is enabled by interactions between the nucleic acid and its ion atmosphere, the mobile sheath of aqueous ions that surrounds and stabilizes it. Understanding the ion atmosphere requires the interplay of experiment and theory. However, even an apparently simple experiment to probe the ion atmosphere, measuring the dependence of DNA duplex ...
