Characterization of the Interaction of Known G‐quadruplex Ligands With a Minimal i‐Motif Structure

open access: yesChemistry – A European Journal, EarlyView.
The destabilization of a minimal i‐Motif (iM) structure by TMPyP4 is driven by ligand recognition of one terminal iM structural domain. ABSTRACT Peculiar genomic regions are prone to evolve transiently from double‐helix DNA to noncanonical secondary structures in response to physiological stress.

A Cytosine‑Bulged (3+1) Hybrid G‑Quadruplex Formed by the Chicken DNA Replication Origin

open access: yesChemistry – A European Journal, EarlyView.
The first high‐resolution structure of an OGRE‐derived G‐quadruplex from the chicken β‐globin replication origin reveals an intramolecular three‐layer (3+1) hybrid fold with a cytosine bulge and an unprecedented 5'‐outer‐quartet anti guanine, creating a distinctive surface for molecular recognition.

Introduction of a Double‐Headed Nucleotide Into G‐Quadruplex DNA: Position‐Dependent Stabilization and Structural Insights

open access: yesChemistry – A European Journal, EarlyView.
A double‐headed bis‐guanine (G) nucleotide (GG) was evaluated as a noncanonical building block in G‐quadruplexes (G4s). Biophysical and computational analyses reveal that GG can directly participate in G‐tetrads and strongly stabilize G4s in a position‐ and topology‐dependent manner. These findings establish design rules for using GG to engineer highly

Utility of Fine Needle Aspiration Supernatant for Real‐Time PCR–Based Mutation Analysis in Non–Small Cell Lung Cancer

open access: yesDiagnostic Cytopathology, EarlyView.
ABSTRACT Background The emergence of personalized therapy and molecular sequencing has significantly transformed the management of advanced non–small cell lung carcinoma (NSCLC). Supernatants obtained from fine needle aspiration (FNA) have been shown to be a reliable source of high‐quality nucleic acid for molecular testing.

Intestinal Epithelial Memory: From Inflammatory Imprinting to Metabolite‐Shaped Immune Tolerance

open access: yesBarrier Immunity, EarlyView.
ABSTRACT Intestinal epithelial cells are rapidly renewing barrier cells that maintain compartmentalization between the luminal environment and the mucosal immune system through epithelial transport, antimicrobial defense, secretory programs, and cytokine‐mediated communication.
