Peptide‐Ligand Cooperative Interplay Drives Gold Nanoparticle Encapsulation by Protein Cages

open access: yesSmall, EarlyView.
Gold nanoparticle encapsulation within protein cages is governed by salt‐dependent binding energetics and cooperative peptide–ligand interactions. Ligands enhance electrostatic attraction while peptides extend recruitment and prevent kinetic trapping, enabling robust cargo loading. This molecular‐level insight links experiments and simulations, guiding

Enhanced through‐bond energy transfer‐based bioorthogonal probe enables catalytic‐amplified and sensitive detection of microRNA‐21 for clinical lung cancer diagnosis

open access: yesSmart Molecules, EarlyView.
Inverse Diels‐Alder Cycloaddition Reaction was developed for ultrasensitive miR‐21 detection. Based on the enhanced Through‐Bond Energy Transfer and catalytic amplification, it shows a detection limit of 3.58 × 10−18 M and 100 aM–100 nM linear range. It enables high‐contrast cell/tissue imaging and distinguishes lung cancer patients in serum, promising

Thermodynamics of Nucleic Acid Structural Modifications for Biotechnology Applications

open access: yes, 2011
The repertoire of chemistry available to native nucleotides in DNA and RNA is limited to the purine and pyrimidine functional groups, along with the special role of the 2’-hydroxyl of RNA. The nucleobases have exocyclic amino groups and imines, neither of which is highly reactive or a good candidate for catalytic function.

Prostate cancer diagnosis using plasma extracellular vesicles isolated via aqueous two‐phase systems

open access: yesVIEW, EarlyView.
Abstract Prostate cancer (PCa) is the second most prevalent cancer in men, with early detection and precise staging remaining critical for improving outcomes. While PSA tests and biopsies are widely used, they suffer from low specificity and often lead to unnecessary procedures.

Nonthermal plasma approaches for combating implant‐associated infections: A compendious review

open access: yesVIEW, EarlyView.
Implant‐associated infections pose serious clinical challenges. Non‐thermal plasma (NTP) modifications overcome this bottleneck in distinct ways relative to traditional sterilization methods. Gas‐phase plasmas generate highly energetic species, UV radiation and reactive oxygen/nitrogen species (RONS), which alter the implant surface properties.

The potential for biased signalling in the P2Y receptor family of GPCRs

open access: yesBritish Journal of Pharmacology, EarlyView.
The purinergic receptor family is primarily activated by nucleotides, and contains members of both the G protein coupled‐receptor (GPCR) superfamily (P1 and P2Y) and ligand‐gated ion channels (P2X). The P2Y receptors are widely expressed in the human body, and given the ubiquitous nature of nucleotides, purinergic signalling is involved with a plethora

KU80 suppresses endonuclease G activity to preserve genomic integrity

open access: yesThe FEBS Journal, EarlyView.
Under normal conditions, EndoG remains restricted to mitochondria and the genome remains intact. When KU80 is absent, EndoG translocates into the nucleus, where it promotes DNA fragmentation and genomic instability. Thus, this work highlights the importance of KU80 in tightly controlling EndoG localization to preserve genome stability.

Contrasting effects of different molecular crowding environments on base‐pair opening/closing dynamics of DNA triplex structures

open access: yesThe FEBS Journal, EarlyView.
Base‐pair opening and closing regulate nucleic‐acid structure, stability, and function, but how these motions behave under intracellular molecular crowding remains unclear. Using NMR, we quantified these dynamics in a DNA triplex under two crowder‐reconstituted environments that mimic cellular crowding.
