N6‐Methyladenosine (m6A) in Liver Disease: Pathogenic Mechanisms and Therapeutic Potential

iNew Medicine, EarlyView.
ABSTRACT Accumulating evidence highlights the critical role of epigenetic modifications, particularly N6‐methyladenosine (m6A), in liver disease. As the most abundant RNA modification in eukaryotic cells, m6A is dynamically regulated by multicomponent m6A methyltransferases (e.g., METTL3 and METTL14), demethylases (FTO and ALKBH5), and m6A‐binding ...

Proteomic Characterization of AS1411 Reveals ATP6AP1 as a Mediator of Triple‐Negative Breast Cancer Progression

PROTEOMICS, EarlyView.
ABSTRACT Triple‐negative breast cancer (TNBC) is an aggressive subtype of breast cancer characterized by high metastatic potential, poor prognosis, and limited effective therapeutic options. In this study, we investigated the molecular mechanisms underlying the anticancer effects of the nucleolin (NCL)‐targeting DNA aptamer AS1411 using label‐free ...

Structural mechanism of insulin receptor activation by a dimeric aptamer agonist

Experimental and Molecular Medicine
Insulin binding to the insulin receptor (IR) triggers signaling pathways that regulate glucose uptake and cell growth. In previous work, we identified a DNA aptamer, A62, which partially activates the IR.

Three phases in the evolution of the standard genetic code: how translation could get started [PDF]

, 2007
A primordial genetic code is proposed, having only four codons assigned, GGC meaning glycine, GAC meaning aspartate/glutamate, GCC meaning alanine-like and GUC meaning valine-like.

High Sensitivity Cardiac Troponin I Detection via MP‐Locked Aptamer and Multimeric DNAzyme‐Coupled Hyperbranched Hybridization Chain Reaction

Small, EarlyView.
We report a magnetic particle anchored locked aptamer platform integrated with hyperbranched HCR and DNAzyme amplification for enzyme‐free, ultrasensitive detection of cardiac troponin I. The assay achieves a 0.25 ng/L detection limit within 25 minutes and enables cross‐species MI detection, with machine learning classification reaching 90% accuracy ...

Multiplex visual nucleic acid detection via isothermal cascaded transcription of fluorescent RNA aptamers

VIEW, EarlyView.
(1) Existing multiplex nucleic acid detection struggles to combine high sensitivity, visual readout, and instrument‐free use, which is vital for rapid infection and antibiotic resistance diagnosis. (2) We developed MAGIC, integrating isothermal cascaded amplification and fluorescent RNA aptamer transcription, achieving 10 aM sensitivity, 100% accuracy ...
