Hydration of a B-DNA Fragment in the Method of Atom-atom Correlation Functions with the Reference Interaction Site Model Approximation

open access: yes, 1998
We propose an efficient numerical algorithm for solving integral equations of the theory of liquids in the Reference Interaction Site Model (RISM) approximation for infinitely dilute solution of macromolecules with a large number of atoms.

Synthetic metallomolecules as agents for the control of DNA structure [PDF]

open access: yes, 2007
This tutorial review summarises B-DNA structure and metallomolecule binding modes and illustrates some DNA structures induced by molecules containing metallic cations. The effects of aquated metal ions, cobalt amines, ruthenium octahedral metal complexes,

Effectiveness of Multivitamins vs Folic Acid on Prevention of Neural Tube Defects in Mouse Genetic Models and Human Organoids

open access: yesAdvanced Science, EarlyView.
Folic acid (FA) and multivitamins/minerals (MVM) are recommended for the prevention of neural tube defects (NTDs). Using a novel human neural tube‐like organoid system and mouse models, the study compares the effectiveness of two supplements on NTDs and cellular behaviors.

DNA‐Inspired Multi‐Functional Double‐Cross‐Linking Self‐Healing Hydrogel Promotes the Healing of Diabetic Wounds

open access: yesAdvanced Science, EarlyView.
A self‐healing hydrogel crosslinked with dynamic nucleobase‐mimetic bonds delivers curcumin‐loaded exosomes. It promotes diabetic wound healing via a synergistic combination of antibacterial, anti‐inflammatory, pro‐angiogenic, and immunomodulatory mechanisms, providing a comprehensive therapeutic approach.

Tobacco Smoke Exposure From Prenatal To Adolescent Periods Drives IBD Pathogenesis: Dynamic DNA Methylation Signatures Across Lifespan Stages

open access: yesAdvanced Science, EarlyView.
This study illustrates that maternal smoking during pregnancy (MSDP) is an independent risk factor for IBD in offspring, and DNA methylation serves as a key mechanistic pathway connecting early‐life smoking exposure with IBD risk in offspring. That highlights the urgent need for preventive interventions targeting prospective parents and minors to ...

Intermediate filaments spatially organize intracellular nanostructures to produce the bright structural blue of ribbontail stingrays across ontogeny

open access: yesFrontiers in Cell and Developmental Biology
In animals, pigments but also nanostructures determine skin coloration, and many shades are produced by combining both mechanisms. Recently, we discovered a new mechanism for blue coloration in the ribbontail stingray Taeniura lymma, a species with ...

Design and Properties of Ligand-Conjugated Guanine Oligonucleotides for Recovery of Mutated G-Quadruplexes

open access: yesMolecules, 2018
The formation of a guanine quadruplex DNA structure (G4) is known to repress the expression of certain cancer-related genes. Consequently, a mutated G4 sequence can affect quadruplex formation and induce cancer progression. In this study, we developed an

Depletion of the RNA‐Editing Enzyme ADAR1 Invigorates the Antitumor Immunity of NK Cells

open access: yesAdvanced Science, EarlyView.
ADAR1 is upregulated in NK cells from melanoma patients, impairing their function. Its loss enhances NK cell tumor infiltration and cytotoxicity in vitro and in vivo. Mechanistically, ADAR1 deficiency destabilizes CD38 mRNA to reduce its expression, thereby increasing NK cell mobility and killing, which nominates it as a therapeutic target for NK cell ...

Generation, repair and replication of guanine oxidation products

open access: yesGenes and Environment, 2017
Guanine is the most readily oxidized of the four DNA bases, and guanine oxidation products cause G:C-T:A and G:C-C:G transversions through DNA replication.

Genome‐Wide Association Analyses Reveal the Genetic Basis of EMS Mutagenesis Efficiency in Rice

open access: yesAdvanced Science, EarlyView.
Based on large‐scale screening of 420 rice accessions, GWAS identified the Rc locus as a key regulator of EMS mutagenesis efficiency. Functional Rc alleles enhance both seed survival and genome‐wide mutation frequency by boosting antioxidant enzyme activities (CAT, SOD, POD) and reducing oxidative damage.
