Molecular Dynamics Simulation of Melting of the DNA Duplex with Silver-Mediated Cytosine–Cytosine Base Pair

Computation
Metal-mediated base pairs in DNA double helix molecules open up broad opportunities for biosensors based on DNA clusters with silver due to their low toxicity and applicability in drug design.

m6A‐Mediated Glycolysis by IL‐37 Drives T Cell Metabolic Reprogramming to Regulate Colitis

Advanced Science, EarlyView.
This study identifies an IL‐37/SIGIRR‐METTL14 regulatory axis that suppresses global m6A modification in CD4+ T cells. IL‐37 signaling, mediated through SIGIRR, inhibits IRAK4 and JNK phosphorylation, leading to downregulation of the methyltransferase METTL14.

A 7-Deazaadenosylaziridine Cofactor for Sequence-Specific Labeling of DNA by the DNA Cytosine-C5 Methyltransferase M.HhaI

Molecules, 2015
DNA methyltransferases (MTases) catalyze the transfer of the activated methyl group of the cofactor S-adenosyl-l-methionine (AdoMet or SAM) to the exocyclic amino groups of adenine or cytosine or the C5 ring atom of cytosine within specific DNA sequences.

DddA homolog search and engineering expand sequence compatibility of mitochondrial base editing

Nature Communications, 2023
There is a need to improve and expand mitochondrial base editing tools. Here the authors identify a DddA homolog from Simiaoa sunii (Ddd_Ss) which can efficiently deaminate cytosine in dsDNA; they develop cytosine base editors and introduce mutations at ...

ProSiteHunter: A Unified Framework for Sequence‐Based Prediction of Protein‐Nucleic Acid and Protein‐Protein Binding Sites

Advanced Science, EarlyView.
This study proposed a unified sequence‐based framework for protein binding site prediction, which adopted a tri‐track semantic multi‐source feature fusion strategy to effectively capture diverse macromolecular interaction sites and further improved the accuracy of antibody‐antigen interaction prediction.

Targeting Dnmt3a/m5C/RelA Axis Attenuates Microglia Inflammatory Response and Improves Postoperative Recovery in Chronic Compressive Cervical Spinal Cord Injury

Advanced Science, EarlyView.
A pro‐inflammatory microglial subset persists after decompression in chronic compressive cervical spinal cord injury and shows enhanced Dnmt3a‐driven m5C signaling. By stabilizing RelA mRNA, this axis sustains NF‐κB activation and postoperative neuroinflammation.

Synergistic HMGN1 and VP64 Fusions Potentiate High‐Precision and PAM‐Flexible Base Editing

Advanced Science, EarlyView.
A novel CDA1Δ‐SpRY architecture fused with HMGN1 and VP64 yields a nearly PAM‐less base editing platform. By focusing cytosine conversion predominantly at position −18, this synergistic complex ensures highly precise targeting. Demonstrating enhanced efficiency across diverse models, including yeast and rice, the platform offers a robust solution for ...

Activity on non-methylated DNA limits the use of endonuclease MspJI for epigenetic analyses

All Results Journals: Biol, 2018
Cytosine methylation of DNA in mammals has been associated with both physiological and pathological changes in gene-expression. DNA treatment with methylation sensitive and/or dependent restriction enzymes, followed by PCR amplification is a widely used ...

CHCHD10 Mitigates Alzheimer's Disease‐Related Phenotypes in Association With Epigenetic Remodeling in Directly Reprogrammed Neurons

Advanced Science, EarlyView.
CHCHD10 loss in Alzheimer's disease is associated with mitochondrial dysfunction, epigenomic disruption, and tau pathology. Restoration of CHCHD10 shifts DNA methylation toward a non‐disease state and reduces tau and amyloid pathology, with KATNAL2 acting as a downstream effector.
