Metabolisms of Nucleosides in Bacteria

Agricultural and Biological Chemistry, 1967
Pyrimidine nucleoside phosphorylases obtained from Er. carotovora and Cor. sepedonicum were purified by means of ammonium sulfate fractionation and DEAE-cellulose column chromatography. Some properties of these enzyme were also studied. The enzyme from Cor.

Disruption of Gut Microbiota‐Mediated De Novo NAD+ Synthesis Contributes to the Development of Polycystic Ovary Syndrome

Advanced Science, EarlyView.
This study demonstrates that patients with PCOS exhibit altered gut microbial profiles, and FMT from PCOS patients induces PCOS‐like symptoms in mice. Specifically, gut dysbiosis reduces 3‐HAA levels in the context of PCOS. Administration of 3‐HAA to mice alleviates PCOS by promoting de novo NAD+ synthesis.

Tumor Intrinsic METTL5 Modulates ATF4 Translation to Prevent T Cell‐Induced Ferroptosis in Ovarian Cancer

Advanced Science, EarlyView.
An integrative analysis combining in vitro genome‐wide immune screens, in vivo ICB screens, and clinical data mining identifies METTL5 as a key tumor‐intrinsic immune factor. Mechanistic studies further reveal the importance of the METTL5‐ATF4‐SLC7A11/SLC3A2‐ferroptosis axis in modulating antitumor immune responses. These findings highlight METTL5 as a

Targeting HDAC and PARP Enhances STING‐Dependent Antitumor Immunity in STING‐Deficient Tumor

Advanced Science, EarlyView.
Dual HDAC and PARP inhibition restores STING signaling, enhances interferon response, and boosts antitumor immunity in STING‐deficient tumors. . Abstract The stimulator of interferon genes (STING)‐mediated innate immune pathway plays an important role in tumor immunosurveillance.

Integrating Metabolic Modulation and Nanomedicine for Cancer Immunotherapy

Advanced Science, EarlyView.
Metabolic rewiring in cancer is mapped across glucose, amino acid, lipid, nucleotide, and mitochondrial pathways, with emphasis on immune regulation. The review integrates mechanisms linking these pathways to tumor progression and therapy resistance, and profiles nanomaterial platforms that both deliver therapeutics and actively reprogram ...

Steric‐Adaptive Biocatalysis: Imine Reductase‐Mediated Dynamic Kinetic Resolution for Atroposelective Synthesis of Hindered Biaryl Amines

Advanced Science, EarlyView.
An unusual IRED platform is reported, enabling efficient DKR via reductive amination without any evolutionary engineering. The system accommodates extremely sterically demanding substrates, including naphthyl and quinoline derivatives, delivering naphthyl‐aryl and quinoline‐aryl amine atropisomers with excellent efficiency and stereocontrol (over 80 ...

Dynamic eIF3‐S6 Phase Separation Switch Instructed by m6A Modification Drives the Molting of Locusts

Advanced Science, EarlyView.
This research reveals that reduced m6A modifications during insect molting trigger liquid–liquid phase separation (LLPS) of the m6A reader eIF3‐S6, which binds and stabilizes key molting mRNAs, including EcR and Cht10. Disrupting m6A or LLPS causes cuticle remodeling defects and molting failure, highlighting the synergistic control of gene expression ...

Synthesis, Biological Activity, and Molecular Dynamics Simulations of LNA‐Charge Neutral Linkages for Enhanced Splice‐Switching Antisense Oligonucleotides

Angewandte Chemie, EarlyView.
Splice‐switching oligonucleotides are used to treat severe genetic conditions including Duchenne Muscular Dystrophy, but new chemistries are urgently required to improve their efficacy. In this work locked nucleic acid (LNA) is coupled to different charge neutral DNA backbones which are studied by structural, thermodynamic, and biological methods.
