γ-PNA PREORGANIZATION: SYNTHESIS OF MODEL DIMER AND ITS STRUCTURE STUDY BY 2D NMR SPECTROSCOPY

Тонкие химические технологии, 2017
The synthesis of a dimer consisting of γ-thymine chiral monomer based on L-Ala and thymine aeg-PNA monomer (synthesized from deuterated glycine), in which the methylene protons of the pseudopeptide residue were exchanged with deuterium atoms, was ...

Microbial metabolites in tumor epigenetic regulation

iMeta, EarlyView.
The gut microbiome modulates tumor epigenetic regulation through bioactive metabolites derived from dietary substrates. Microbiota‐produced SCFAs, secondary BAs, one‐carbon metabolites, and tryptophan‐derived ligands regulate histone acetylation, DNA methylation, and chromatin remodeling via HDAC, DNMT, AhR, and metabolic cofactor‐dependent pathways ...

Epigenetic Regulation in the Pathogenesis of Renal Inflammation: Insights and Therapeutic Potentials

iNew Medicine, EarlyView.
ABSTRACT Renal inflammation is a common pathological process in various kidney diseases, often initiated by factors such as toxins, ischemia, or autoimmune reactions. This inflammatory response can result in structural damage and a rapid decline in renal function.

Noncanonical Nucleotides in the Genome Around the Maternal‐Zygotic Transition

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
In this paper, Kazzazi et al. provide a comprehensive review of the dynamics of nonconventional nucleotides in the genome during early developmental stages, hypothesizing a potential role for these nucleotides in the activation of the zygotic genome. ABSTRACT From the very moment of fertilization and throughout development, the cells of animal embryos ...

Identification of Natural and Artificial Modifications in DNA at the Nanometer Level

Journal of Raman Spectroscopy, EarlyView.
Short single‐ and double‐stranded DNA sequences with natural and artificial markers are examined at ambient conditions using TERS to identify and localize the labelled nucleobases. The differences between single‐ and double‐stranded DNA should provide clear experimental evidence of the extreme surface sensitivity of TERS.

Aliphatic Poly(Carbonate)s with Acid Responsive Release Mechanisms for Micellar Anti‐Tumor Drug Delivery

Macromolecular Rapid Communications, EarlyView.
Micellar systems based on biodegradable aliphatic polycarbonates and acid‐responsive triggers enhance drug solubility, stability, and tumor‐selective release. This review covers micelles with acid‐cleavable drug linkages and those that disassemble via acid‐sensitive functionalities.
