A Method for Constructing Nucleosome Arrays with Spatially Defined Histone PTMs and DNA Damage

Angewandte Chemie, EarlyView.
This work advances methodology by addressing challenges in mimicking the complex in vivo spatial relationships of histone acetylation and DNA damage. The combination of an abiotic/enzymatic hybrid catalyst system (ABEHCS) and the plug‐and‐play method has constituted a versatile platform to construct nucleosome arrays with precise histone acetylation ...

Bioenergetics and gene silencing approaches for unraveling nucleotide recognition by the human EIF2C2/Ago2 PAZ domain.

PLoS ONE, 2014
Gene silencing and RNA interference are major cellular processes that control gene expression via the cleavage of target mRNA. Eukaryotic translation initiation factor 2C2 (EIF2C2, Argonaute protein 2, Ago2) is considered to be the major player of RNAi ...

Antagonism of Morphine Analgesia by Adenine, Adenosine, and Adenine Nucleotides

Experimental Biology and Medicine, 1973
SummaryAntagonism of the antinociceptive action of morphine in mice by prior parenteral administration of cAMP has been confirmed using two additional analgesic testing procedures, the hot-plate test and the stretching test. The analgesia-antagonistic property, however, is not specific for cAMP because it also occurred after pretreatment with compounds

Shrimp Virus Regulates ROS Dynamics via the Nrf2 Pathway to Facilitate Viral Replication

Advanced Science, EarlyView.
Viruses manipulate host ROS as a strategy to achieve successful infection. WSSV exploits Nrf2 pathway to maintain ROS homeostasis and establishes a positive feedback loop to facilitate WSSV replication. Wsv220 competitively binds to Keap1 to activate Nrf2. Nrf2 up‐regulates LvG6PDH to produce more NADPH and GSH to eliminate excessive ROS.

Switching on Supramolecular DNA Junction Binding Using a Human Enzyme

Angewandte Chemie, EarlyView.
Stimulus responsive control of DNA junction formation: Enzyme action cleaves flexible arms from a metallo‐supramolecular cylinder, transforming an inert metallo‐supramolecular structure into an active metallo‐supramolecular agent, and switching on its ability to assemble, bind and stabilize DNA three‐way junction structures.

Determination of total potentially available nucleosides in bovine milk [PDF]

, 2010
Bovine colostrum and milk samples were collected from two herds over the course of the first month post-partum, pooled for each herd by stage of lactation and total potentially available nucleosides were determined.

RFWD3 Reprograms Nucleotide Metabolism Through PHGDH to Induce Chemoresistance In Osteosarcoma

Advanced Science, EarlyView.
RFWD3 is identified as a key regulator of cisplatin (DDP) sensitivity in osteosarcoma using a genome‐wide CRISPR screen. RFWD3 promotes PHGDH ubiquitination, enhancing NAD+‐mediated nucleotide biosynthesis. Knocking out RFWD3 sensitized osteosarcoma cells to DDP.

Beyond Structure: Methylation Fine‐Tunes Stability and Folding Kinetics of bcl2Mid G‐Quadruplex

Angewandte Chemie, EarlyView.
The introduction of a single 5‐methylcytosine into a G‐rich sequence originating from the B‐cell lymphoma 2 (BCL2) gene promoter affects both the folding kinetics and thermodynamics of the two G4 structures and thus plays a crucial role in regulating G4 folding pathways, which has significant implications for the control of gene expression.

Glycolysis‐Derived Lactate Induces ACSL4 Expression and Lactylation to Activate Ferroptosis during Intervertebral Disc Degeneration

Advanced Science, EarlyView.
Glycolysis‐derived lactate activates nucleus pulposus cell ferroptosis via Histon H3K18la‐mediated ACSL4 transcription and ACSL4 lactylation and aggravate intervertebral disc degeneration. Inhibiting glycolysis via gene silencing or chemical intervention reduces the production of lactate and ameliorates ferroptosis activation and nucleus pulposus ...
