Adenine methylation in zein genes
, 2013 This paper reports the novel finding of adenine methylation in higher plants. Comparison of restriction patterns of genomic maize DNA digested with enzymes MboI and Sau3A enabled us to detect the existence of adenine methylation in zein genes.

Spectroscopic Evaluation of Novel Adenine/Thymine-Conjugated Naphthalenediimides: Preference of Adenine-Adenine over Thymine-Thymine Intermolecular Hydrogen Bonding in Adenine- and Thymine-Functionalized Naphthalenediimides [PDF]
, 2019 The synthesis and spectroscopic characterization of novel nucleobase (adenine/thymine)-conjugated naphthalenediimides (NDIs), namely, NDI-AA, NDI-TT, and NDI-AT have been successfully achieved. NDI-AA, NDI-TT and NDI-AT have similar absorption in the 300–

Advanced Science, EarlyView.FBL directly binds to and stabilizes SIRT1 by blocking its ubiquitin‐proteasome degradation, thereby sustaining nicotinamide metabolism and redox homeostasis to counteract cellular senescence in ESCC. Genetic and pharmacological suppression of FBL sensitizes tumor cells to senolytic therapy.

Folding of the Adenine Riboswitch
Chemistry & Biology, 2006 The pbuE adenine riboswitch undergoes metal ion-dependent folding that involves a loop-loop interaction. Binding of 2-aminopurine to the aptamer domain strongly correlates with the ability of the loops to interact, and single-molecule FRET studies reveal that folding proceeds via a discrete intermediate. Folding occurs in the absence of adenine ligand,

Vertical Ionization Energies of Adenine and 9-Methyl Adenine
, 2016 Vertical ionization energies of 9-H adenine and 9-methyl adenine have been calculated with the following, ab initio, electron propagator methods: the outer valence Green’s function (OVGF), partial third-order theory (P3), and the third-order algebraic ...

Advanced Science, EarlyView.Magneto‐NIR‐II‐programmed NFSH nanozymes integrate magnetic blood–brain barrier (BBB) translocation, CD44 targeting, multimodal imaging, and cascade catalytic therapy for glioblastoma. Alternating magnetic fields and NIR‐II irradiation amplify ferroptosis, release H2S, suppress autophagic and mitophagic repair, and reshape the immune microenvironment ...

Advanced Science, EarlyView.This work identified CPD3a as a potent, stable C‐nucleoside cordycepin derivative. When formulated into microneedle array for topical treatment, it ameliorated psoriasis by rebalancing immunity and enhancing antioxidant defenses. ABSTRACT Psoriasis is a chronic inflammatory disorder characterized by immune dysregulation and epidermal hyperplasia ...

Chemical Bond‐Orchestrated Energy Depletion to Augment Lung Cancer Chemo‐Immunotherapy
Advanced Science, EarlyView.This study grafted dichloroacetic acid (DCA) into perylenediimide (PDI) skeleton via ionic or covalent bond to create novel metabolic agent PDIC‐AC and PDIC‐NAC, explicitly elaborated the underlying energy metabolism and therapeutic mechanism, and developed a promising strategy for energy metabolism‐targeting chemo‐immunotherapy by chemical bond ...
