Radiosensitizing Nucleosides [PDF]

JNCI Journal of the National Cancer Institute, 1996
Chemotherapeutic drugs that perturb nucleotide metabolism have the potential to produce substantial sensitization of tumor cells to radiation treatment. The process is called radiosensitization, and the agents that induce it are called radiosensitizers.

Cholesterol in mRNA‐Lipid Nanoparticles can be Replaced with the Synthetic Mycobacterial Monomycoloyl Glycerol Analogue MMG‐1

Advanced Functional Materials, EarlyView.
This study demonstrates that cholesterol in messenger RNA‐lipid nanoparticles (mRNA‐LNPs) can be completely replaced with an immunopotentiating lipid, i.e., a synthetic analogue of the C‐type lectin receptor agonist monomycoloyl glycerol (MMG‐1), without compromising physicochemical properties, in vivo transfection efficiency, and immunogenicity of the

Root-secreted nucleosides: signaling chemoattractants of rhizosphere bacteria

Frontiers in Plant Science
The rhizosphere is a complex ecosystem, consisting of a narrow soil zone influenced by plant roots and inhabited by soil-borne microorganisms. Plants actively shape the rhizosphere microbiome through root exudates.

Inhibition of Tyrosyl-DNA Phosphodiesterase 1 by Lipophilic Pyrimidine Nucleosides

Molecules, 2020
Inhibition of DNA repair enzymes tyrosyl-DNA phosphodiesterase 1 and poly(ADP-ribose)polymerases 1 and 2 in the presence of pyrimidine nucleoside derivatives was studied here. New effective Tdp1 inhibitors were found in a series of nucleoside derivatives

Novel 3D‐Printed Biophotonic Scaffold Displaying Luminescence under Near‐Infrared Light for Photopharmacological Activation and Biological Signaling Compound Release

Advanced Healthcare Materials, EarlyView.
Despite significant efforts in developing novel biomaterials to regenerate tissue, only a few of them have successfully reached clinical use. It has become clear that the next generation of biomaterials must be multifunctional. Smart biomaterials can respond to environmental or external stimuli, interact in a spatial‐temporal manner, and trigger ...

Development of a Modular Ribonucleoprotein Complex as a General Strategy to Deliver RNAi Therapeutics

Advanced Healthcare Materials, EarlyView.
A modular and customizable RNAi therapeutics delivery platform composed of a pseudosymmetric human RNA binding protein‐siRNA complex (SmiRNP) is developed. By fusing a targeting module and an endosomal escape peptide onto the delivery platform, SmiRNP successfully delivered siRNA to silence the KRAS oncogene in a colorectal carcinoma cell line, leading
