Suppression of Retinal Neovascularisation by Tetrahedral Framework Nucleic Acids‐Resveratrol Via Dual Anti‐Angiogenesis and Anti‐Inflammation

Cell Proliferation, EarlyView.
Resveratrol‐loaded tetrahedral framework nucleic acids (tFNAs‐RSV) enable concurrent anti‐angiogenic and anti‐inflammatory therapy, enhancing ocular delivery and bioactivity. In hypoxia‐induced retinal neovascularisation, tFNAs‐RSV reduce neovascular lesions, vascular leakage and inflammatory infiltration by suppressing HIF‐1, p38 MAPK and NF‐κB p65 ...

ssDNA and ssRNA Promote Phase Condensation of SAMHD1

Biochemistry
SAMHD1 (SAM domain and HD domain-containing protein 1) is a deoxynucleoside triphosphate triphosphohydrolase (dNTPase) with functions in viral restriction, R-loop resolution, DNA repair, telomere maintenance, ssRNA homeostasis, and regulation of self-nucleic acids. As a dNTPase, SAMHD1 functions as an allosterically activated tetramer, where binding of

Quantitative analysis of DNA‐GATA1 binding alterations linked to hematopoietic disorders

The FEBS Journal, EarlyView.
Native holdup allows the quantitative determination of affinities between full‐length transcription factors and DNA. Mutations in either the protein or the DNA can modulate binding strength, which can be precisely quantified using this approach. Applied to GATA1, it revealed mutations that alter DNA binding.

Homologous recombination mutants cause differing lethality between h− and h+ Schizosaccharomyces pombe strains due to mat1 heterochromatin

The FEBS Journal, EarlyView.
Homologous recombination (HR) in Schizosaccharomyces pombe is essential when mating‐type switching–induced double‐strand breaks (DSBs) form at the mat1 locus. In h90 and h− strains, efficient mat1 DSB formation renders HR indispensable unless suppressors block these breaks.

JAK2V617F+ single-stranded DNA modulates exosome complex activity and DNA-sensing pathways in myeloproliferative neoplasms

Molecular Therapy: Nucleic Acids
Philadelphia chromosome-negative myeloproliferative neoplasms (Ph-MPNs) are characterized by excessive myeloid cell proliferation due to mutations in hematopoietic stem/progenitor cells, most notably JAK2V617F mutation.

Aptamer‐mediated outer membrane destabilization overcomes low permeability resistance in Pseudomonas aeruginosa

The FEBS Journal, EarlyView.
DNA aptamers, Apt 60 and Apt 173, target the BamA protein to compromise outer membrane integrity in Pseudomonas aeruginosa, making it susceptible to Azithromycin, an antibiotic that is otherwise poorly effective due to the low‐permeability membrane.

Coupling of both a transactivation module and a double‐stranded DNA‐binding domain boosts Cas12i3 variant‐based cytosine and adenine editing in plants

Journal of Integrative Plant Biology, EarlyView.
Fusions of a transactivation module and a double‐stranded DNA‐binding domain produced effective Cas12i3 variant‐based cytosine and adenine base editors, with improved C‐to‐T and A‐to‐G base editing efficiency and expanded editing window. Generated herbicide‐resistant rice germplasm by using these base editors demonstrates their potential for precise ...

Synergistic engineering of Casδ nuclease for robust genome editing

Journal of Integrative Plant Biology, EarlyView.
A hierarchical engineering strategy was used to enhance the editing activity of Casδ, yielding an optimized variant termed enCasδ. This variant enables robust genome editing in animal cells and plants, with overall editing performance comparable to that of SpCas9 and other Cas12 nucleases.

R‐Loops Mediated Odontogenic Differentiation of hDPSCs by Activating the cGAS‐STING Pathway Under Inflammatory Microenvironment

Oral Diseases, EarlyView.
ABSTRACT Background R‐Loops are three‐stranded DNA/RNA hybrids implicated in immune responses. Their role in mesenchymal stem cell differentiation, particularly in dental pulp regeneration under inflammation, remains unclear. Methods Rat pulpo‐dentinal complex (PDC) injury models and LPS‐stimulated human dental pulp stem cells (hDPSCs) were used.

Writing Big in Plant Genomes: Advances, Challenges and Strategies for Targeted Large‐Fragment DNA Insertion

Plant, Cell &Environment, EarlyView.
ABSTRACT Precise genome editing has transformed plant biology and crop improvement by enabling targeted modification of endogenous loci. Beyond gene knockout and base editing, the site‐specific insertion of exogenous DNA, particularly large DNA fragments, has become a central goal for engineering complex traits, reconstructing metabolic pathways and ...
