Advances and Strategies in Enhancing mRNA Cancer Vaccines

Advanced Materials, EarlyView.
Messenger RNA (mRNA) vaccines offer a powerful approach for cancer immunotherapy, but their clinical impact remains limited by delivery challenges and suboptimal immune activation. This review discusses key biological barriers and design strategies—including structural optimization, immunomodulation, organ targeting delivery, and advanced nanocarriers ...

Synthesis and Biological Activity of Reversed Pyrimidine Nucleosides

Croatica Chemica Acta, 2015
An efficient approach to reversed nucleosides which enables their synthesis in gram quantities is described. N-1′-Pyrimidine reversed nucleosides were prepared by treating of the sodium salt of pyrimidine bases with protected 5-tosyl ribose ...

Implementation of FTA Elute Card for Viral RNA Storage and Cost‐Effective Wastewater Surveillance

Advanced Sensor Research, EarlyView.
A strategy is developed for room‐temperature storage of RNA from wastewater using FTA Elute cards, which allow for easy and portable transportation. FTA Elude cards provided a 15.4% recovery of the original RNA with cards, compared to only 0.5% recovery without cards.

Homeostasis of Gut Microbiota Protects against Susceptibility to Fungal Pneumonia

Advanced Science, EarlyView.
Fungal pneumonia induces inflammation, shown by heightened IL‐6, IL‐1β, TNF‐α levels and a growth in Staphylococcus in the alveolar flora. The gut microbiota, acting through the gut‐lung axis via blood, impacts fungal pneumonia susceptibility by altering lung metabolism and inflammatory responses.

5’‐Methylthioadenosine Metabolic Reprogramming Drives H3K79 Monomethylation‐Mediated PAK2 Upregulation to Promote Cadmium‐Induced Breast Cancer Progression by Impairing Autophagic Flux

Advanced Science, EarlyView.
Cadmium, a carcinogenic heavy metal, drives breast cancer progression via metabolic reprogramming and autophagic flux disruption. Multi‐omics revealed cadmium‐induced 5'‐methylthioadenosine depletion activates DOT1L‐mediated H3K79me1 at PAK2 promoter, upregulating PAK2 to block autophagy and driving malignancy. Clinically, 5'‐methylthioadenosine levels

An Enzymatic Flow-Based Preparative Route to Vidarabine

Molecules, 2020
The bi-enzymatic synthesis of the antiviral drug vidarabine (arabinosyladenine, ara-A), catalyzed by uridine phosphorylase from Clostridium perfringens (CpUP) and a purine nucleoside phosphorylase from Aeromonas hydrophila (AhPNP), was re-designed under ...

Nucleoside Transporter Proteins

Current Vascular Pharmacology, 2009
Concentrative nucleoside transporters (CNT; SLC28) and equilibrative nucleoside transporters (ENT; SLC29) mediate the uptake of natural nucleosides and a variety of nucleoside-derived drugs, mostly used in anticancer therapy. SLC28 and SLC29 families consist in three and four members, respectively, which differ in their substrate selectivity and their ...

Super‐Resolution Compatible DNA Labeling Technique Reveals Chromatin Mobility and Organization Changes During Differentiation

Advanced Science, EarlyView.
A novel chromatin‐labeling probe is developed to investigate chromatin mobility during differentiation. The silicon rhodamine–conjugated dCTP is efficiently delivered into iPSCs and NSCs using a synthetic transporter. Super‐resolution microscopy and single‐particle tracking show decreased chromatin mobility during differentiation.
