Transmembrane Transport of cAMP and AMP Using a Two Component Small Molecule Transport System

Angewandte Chemie, EarlyView.
Transmembrane transport of the nucleotides cAMP (cyclic adenosine monophosphate) and AMP (adenosine monophosphate) is challenging, but can be achieved using a two‐component system consisting of a synthetic anionophore (e.g., squaramides) and a lipophilic thymine derivative.

Allosteric regulation accompanied by oligomeric state changes of Trypanosoma brucei GMP reductase through cystathionine-β-synthase domain

Nature Communications, 2020
Trypanosoma brucei guanosine 5′-monophosphate reductase (TbGMPR) catalyses the conversion of GMP to inosine 5′-monophosphate and contains a cystathionine-β-synthase (CBS) domain. Here the authors combine X-ray crystallography and kinetic measurements and

Aptamer Engineering: Strategies for Discovering Functional Nucleic Acids for Next‐Generation Diagnostics and Biosensing

Advanced Science, EarlyView.
The advent of aptamers has highlighted their potential as alternatives to antibodies, overcoming limitations of structural instability and production cost. However, conventional approaches such as SELEX remain slow and labor‐intensive. This review examines recent advances in aptamer engineering, emphasizing in vitro and AI‐driven in silico strategies ...

GSH as an A‐A Type Allosteric Activator of PKM2: Modulating Cancer Cell Homeostasis and Ferroptosis Susceptibility

Advanced Science, EarlyView.
Glutathione (GSH) defines oxidative balance, but can it directly tune central metabolism? The research reveals that GSH binds and potently activates pyruvate kniase M2 (PKM2), rewiring glycolysis and dictating ferroptosis sensitivity. Combining GSH depletion with PKM2 activation triggers mitochondrial damage and lipid peroxidation, profoundly ...

A Sirtuin‐1‐Targeted Gene‐Activating Tetrahedral DNA Attenuates Bladder Fibrosis by Restoring Mitophagy in Fibroblasts via the SIRT1‐FOXO3‐BNIP3 Axis

Advanced Science, EarlyView.
The SIRT1‐targeted saRNA‐delivering tetrahedral DNA (TSA) treatment effectively upregulates SIRT1 expression, which subsequently promotes FOXO3A deacetylation. This deacetylation event relieves FOXO3A's transcriptional repression on the BNIP3 gene, thereby initiating PINK1‐PARKIN‐dependent mitophagy.
