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

Chemistry – 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

Nanomedicine applications in lymphoma: Advancing precision diagnostics, targeted therapeutics, and prospective developments

VIEW, EarlyView.
Lymphoma is a group of blood cancers that can appear in lymph nodes, blood, bone marrow, spleen, liver, or the central nervous system, which makes drug delivery and disease monitoring difficult. This review summarizes how nanomedicine technologies may improve targeted treatment and imaging, while carefully separating approved or guideline‐supported ...

Therapeutic Applications of Stimuli‐Based Release and Engineering of Extracellular Vesicles

Advanced NanoBiomed Research, Volume 6, Issue 8, August 2026.
This review summarizes the effects of endogenous and exogenous stimuli, their effects on the natural release of extracellular vesicles, as well as their uptake and release. It also gives an overview of stimuli‐responsive EVs and their therapeutic applications. Extracellular vesicles (EVs), nano‐ to microsized lipid bilayer membrane‐bound particles, are

AS1411 aptamer-functionalized exosomes in the targeted delivery of doxorubicin in fighting colorectal cancer

Biomedicine & Pharmacotherapy, 2022
Severe side effects of chemotherapy agents on vital organs are the major causes of cancer-related mortality, not merely cancer disease. Encapsulating chemotherapeutic molecules in nanocarriers is a justifiable solution in decreasing the risk of their side effects and boosting the efficiency of treatment. The present study has developed the doxorubicin (

The Bioactivity of D-/L-Isonucleoside- and 2′-Deoxyinosine-Incorporated Aptamer AS1411s Including DNA Replication/MicroRNA Expression

Molecular Therapy: Nucleic Acids, 2017
In this study, chemical modification of 2′-deoxyinosine (2′-dI) and D-/L-isothymidine (D-/L-isoT) was performed on AS1411. They could promote the nucleotide-protein interaction by changing the local conformation.

Nucleotide Metabolism in Health and Disease

MedComm, Volume 7, Issue 8, August 2026.
Nucleotide metabolism, including de novo synthesis, salvage pathways, and catabolism, when dysregulated contributes to cancer, immune disorders, metabolic and urological diseases, and radiation injury. Metabolites such as adenosine, cGAMP, NAD, and cAMP and enzymes like RNR are promising therapeutic targets and biomarkers.
