Monitoring regulation of DNA repair activities of cultured cells in-gel using the comet assay [PDF]

Frontiers in Genetics, 2014
Base excision repair (BER) is the predominant cellular mechanism by which human cells repair DNA base damage, sites of base loss and DNA single strand breaks of various complexity, that are generated in their thousands in every human cell per day as a ...

Global Quantitative Analysis of Ligation Reactions in Self-Assembled DNA Nanostructures at the Single-Nick Level. [PDF]

Small
Ligations of staple strands by ligase at 64 nick sites on DNA origami can be quantitatively mapped. While ligations preferentially occur at the trapezoid edges rather than at inner sites, excellent agreement between the experimental ligation yields and docking simulations suggests that this is a result of variations in the ligase docking probability ...

Dual‐Organelle Secretome Conjugation and Organ‐Uptake Tracking (DuO‐SCOUT) Enables Deep and Sensitive Mapping of the Secreted Proteins

Advanced Science, EarlyView.
A novel dual‐organelle proximity labeling platform, DuO‐SCOUT, decodes the complex landscape of systemic organ‐organ communication by capturing both classical and unconventional secretomes. Application in metabolic models maps the adipose‐to‐brain secretory relay, identifying selective extra‐hypothalamic sites for adipose‐derived factors and expanding ...

Human APOBEC3G suppresses homologous recombination and LIG4‐independent end joining in DNA double‐strand break repair

The FEBS Journal, EarlyView.
Chromosomal DNA double‐strand breaks (DSBs) are repaired by homologous recombination and nonhomologous end joining (NHEJ). Recent work has additionally established theta‐mediated end‐joining (TMEJ) as a mechanism for DSB joining. Cells lacking NHEJ and TMEJ can repair DSBs in a homology‐dependent manner.

Technologies for engineering repetitive DNA

Quantitative Biology, Volume 14, Issue 3, September 2026.
Abstract Repetitive DNA, a fundamental architectural element of genomes, is widespread across organisms and comprises about 54% of the human genome. With advances in long‐read sequencing and bioinformatics approaches, highly repetitive sequences can now be characterized in depth.

DNA–Peptide Crosslinks Placed at Codon 249 of the p53 Tumor Suppressor Gene Induce G to A Transitions in Human Cells

ChemBioChem, Volume 27, Issue 16, 27 August 2026.
DNA‐peptide cross‐links (DpCs) are ubiquitous DNA lesions that form when cellular proteins become covalently trapped on DNA strands and are processed by proteases. DpCs are hypothesized to play a role in antitumor activity of chemotherapeutic drugs and to contribute to aging.

Stress‐Induced Switch in Small Extracellular Vesicle Secretion: From Constitutive ‘Torn Bag Mechanism’ to Exocytosis

Journal of Extracellular Vesicles, Volume 15, Issue 8, August 2026.
Stress‐induced switch. Under stress conditions, small extracellular vesicle release shifts from the constitutive ‘torn bag mechanism’ to exocytosis of multivesicular endosomes. https://BioRender.com/xn1pa1e. ABSTRACT The biogenesis of small extracellular vesicles (sEVs) is only partially understood.

Antibody–Drug Conjugates and Peptide–Drug Conjugates: Current Understandings and Future Perspectives

MedComm, Volume 7, Issue 8, August 2026.
The graphic summarizes the design principles, intracellular trafficking, clinical progress, challenges, and future directions of antibody–drug conjugates (ADCs) and peptide–drug conjugates (PDCs). ADCs consist of a tumor‐targeting antibody, a chemical linker, and a potent payload, whereas PDCs use peptide ligands to deliver cytotoxic, radionuclide, or ...

Chain‐Length Regulation by WzzE Is Necessary for, but Genetically Separable From, Cyclic Enterobacterial Common Antigen Synthesis

Molecular Microbiology, Volume 126, Issue 2, Page 190-207, August 2026.
Here, we demonstrate that polysaccharide chain length regulation plays a distinct role in enabling formation of a cyclic molecule important for the bacterial cell surface. However, this function is necessary, but not sufficient for the cyclic molecule's biosynthesis.
