Diversity, Function and Activity of DNA Viruses in the Qiangyong Proglacial Lake Sediment, the Tibetan Plateau

Environmental Microbiology Reports, Volume 18, Issue 1, February 2026.
This study identified DNA viruses from Qiangyong proglacial lake sediments on the Tibetan Plateau, revealing a highly diverse and previously uncharacterized viral community. These viruses influence microbial community structure and function by infecting key nutrient‐transforming taxa and encoding auxiliary metabolic genes that modulate host metabolism.

Flavones and Aminoflavones Increase the Cytotoxicity of NK Cells in Human Non‐Small Cell Lung Cancer

Journal of Cellular and Molecular Medicine, Volume 30, Issue 4, February 2026.
ABSTRACT Natural flavonoids (flavones) and synthetic aminoflavones are known for their anti‐cancer properties; however, their immunomodulation ability has been largely unexplored. This study determined that synthetic flavones and aminoflavones modulate the cytotoxicity of natural killer (NK) cells against lung cancer cells.

Protecting Groups for the Synthesis of Ribonucleic Acids

CHIMIA, 2001
Methods for the regioselective introduction of alkoxymethyl-groups into the 2?-O-position of 5?-O-dimethoxytritylated, nucleobase-protected ribonucleosides and for the N-alkyloxycarbonylation of adenine and guanine nucleosides were developed ...

Chemical synthesis of novel taurine-containing uridine derivatives [PDF]

, 1905
Recently, novel taurine-containing uridine derivatives were discovered in mammalian mitochondrial tRNAs, and these modified ribonucleosides existed at the first position of the anti-codon.

ClAPRT3‐Mediated Adenine Salvage Pathway Enhances Purine Metabolites to Sustain Seed Vigour During Selfing in Cunninghamia lanceolata

Plant Biotechnology Journal, Volume 24, Issue 2, Page 547-566, February 2026.
ABSTRACT Selfing often causes inbreeding depression, especially during seed and seedling stages. However, some selfed progeny show low inbreeding depression with enhanced vigour, differing from inbred counterparts. This study investigates the molecular mechanisms maintaining seed vigour during selfing in Cunninghamia lanceolata.

Mechanochemical Reactivity of Ribonucleosides Mediated by Inorganic Species: Implications for Extraterrestrial Organic Matter Interpretation

Applied Sciences
Metal species and carbonate are often found as minerals in extraterrestrial rocky bodies. Based on this, the mechanochemical-induced degradation of canonical purine and pyrimidine ribonucleosides into their corresponding nucleobases mediated by some of ...

Aromatic N versus aromatic F : bioisosterism discovered in RNA base pairing interactions leads to a novel class of universal base analogs [PDF]

, 2010
The thermodynamics of base pairing is of fundamental importance. Fluorinated base analogs are valuable tools for investigating pairing interactions. To understand the influence of direct base–base interactions in relation to the role of water, pairing ...
