Xenogeneic Mitochondrial Transplantation Improves Selected Age‐Associated Phenotypes in Mice

Advanced Science, EarlyView.
Yak‐derived xenogeneic mitochondrial transplantation improves selected age‐associated phenotypes in mice, enhances mitochondrial functional readouts, and engages host mitochondrial quality‐control pathways. Broad tissue biodistribution, increased ATP production and mtDNA copy number, reduced ROS levels and dysfunctional mitochondria, improved motility ...

Epigenetic machinery is functionally conserved in cephalopods

BMC Biology, 2022
Background Epigenetic regulatory mechanisms are divergent across the animal kingdom, yet these mechanisms are not well studied in non-model organisms.

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.

Unraveling G‐Quadruplex and i‐Motif Coexistence Within a Double‐Stranded DNA

Angewandte Chemie, EarlyView.
The relative thermodynamic profiles of G‐quadruplex (G4), i‐Motif (iM), and the duplex counterpart tune the simultaneous G4 and iM formation within a double‐stranded (ds) DNA. ABSTRACT DNA can transiently fold into variable arrangements, which are expected to exploit regulatory functions. Guanine‐rich sequences can fold into G‐quadruplexes (G4s), while

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 ...

Determination of Methylation Site of DNA-Methyltransferase NlaX by a Hybrid Method

BioTechniques, 2002
Using a new method based on a combination of bisulfite reaction, the repair enzyme uracil-DNA glycosylase, and synthetic oligodeoxyribonucleotides, the methylation site of DNA-methyltransferase NlaX (M·NlaX) from Neisseria lactamica was established to be

Mammalian DNA (Cytosine-5-)-methyltransferase Expressed in Escherichia coli, Purified and Characterized [PDF]

Journal of Biological Chemistry, 1995
Besides modulating specific DNA-protein interactions, methylated cytosine, frequently referred to as the fifth base of the genome, also influences DNA structure, recombination, transposition, repair, transcription, imprinting, and mutagenesis. DNA (cytosine-5-)-methyltransferase catalyzes cytosine methylation in eukaryotes. We have cloned and expressed
