Multi‐Omics Profiling Reveals Immunomodulatory and Pro‐Regenerative Effects of a Graphene Oxide–Collagen Scaffold in Massive Rotator Cuff Tears

Advanced Science, Volume 13, Issue 44, 7 August 2026.
A graphene oxide/collagen scaffold is developed for chronic massive rotator cuff tear repair. The scaffold improves compressive stability, supports reparative mesenchymal differentiation, and modulates the immune microenvironment. In chronic MRCT models, it reduces muscle degeneration, enhances tendon–bone regeneration, and improves functional recovery,

Structural and Functional Basis of the Fidelity of Nucleotide Selection by Flavivirus RNA-Dependent RNA Polymerases

Viruses, 2018
Viral RNA-dependent RNA polymerases (RdRps) play a central role not only in viral replication, but also in the genetic evolution of viral RNAs. After binding to an RNA template and selecting 5′-triphosphate ribonucleosides, viral RdRps synthesize an RNA ...

Molecular characterization of equine thymidine kinase 1 and preliminary evaluation of its suitability as a serum biomarker for equine lymphoma

BMC Molecular and Cell Biology, 2021
Background Thymidine kinase 1 (TK1) plays a key role in the synthesis of deoxythymidine triphosphate (dTTP) and is thus important for DNA replication and cell proliferation.

A Modular Nucleoside Kinase Cascade for the Synthesis of Ribonucleoside Triphosphates

Biotechnology and Bioengineering, Volume 123, Issue 8, Page 2180-2191, August 2026.
Damm et al. report standardized enzymatic cascades for production of all canonical nucleoside triphosphates from the corresponding nucleosides, using kinase‐catalyzed phosphorylation from acetyl phosphate. Reactions afforded ∼ 100 mM product in near‐quantitative conversion.

Cardiomyocytes disrupt pyrimidine biosynthesis in nonmyocytes to regulate heart repair

The Journal of Clinical Investigation, 2022
Various populations of cells are recruited to the heart after cardiac injury, but little is known about whether cardiomyocytes directly regulate heart repair.

2'‐O‐Acetal Levulinic Ester Ribonucleoside 3'‐Phosphoramidites for the Solid‐Phase Synthesis of Long RNA

Current Protocols, Volume 6, Issue 8, August 2026.
Abstract Solid‐phase RNA synthesis is challenging because the 2'‐hydroxyl requires a protecting group that is stable during chain assembly yet easily removable without degrading the product. Driven by the demand for long RNA therapeutics, we report a synthesis method using 2'‐O‐acetal levulinic ester (ALE) ribonucleoside 3'‐O‐phosphoramidites.

Texture and Neonicotinoid Exposure Shape Bacterial Assemblages and Functions in Agricultural Soils: Responses Over Prolonged Exposure

Environmental Microbiology Reports, Volume 18, Issue 4, August 2026.
In a 28‐day soil microcosm experiment, bacterial communities responded differently to imidacloprid across contrasting soil textures, with soil‐dependent changes in community structure, interaction networks and functional pathways, while overall diversity remained largely stable.

DNA Methylation Shapes Seed‐Borne Microbiome and Proteome Responses During Early Maize‐Beneficial Bacteria Interactions

Plant, Cell &Environment, Volume 49, Issue 8, Page 5477-5496, August 2026.
ABSTRACT Microorganism and plant interactions are crucial for development and environmental adaptation. Plant growth promoting bacteria enhance agricultural productivity in a sustainable manner, while epigenetic modifications such as DNA methylation regulate gene expression and adaptive responses.

A Universal Nucleoside‐to‐Nucleoside‐5′‐Triphosphate Enzyme Cascade Driven by Polyphosphate

Angewandte Chemie International Edition, Volume 65, Issue 31, 27 July 2026.
Nucleoside‐5′‐triphosphates (NTPs) are essential components for the generation of nucleic acids, yet their chemical synthesis is hindered by the low yield of nucleoside phosphorylation. Here, we present a universal, two‐enzyme nucleoside‐to‐NTP cascade that is driven by polyphosphate.
