Microbiota-Sourced Purines Support Wound Healing and Mucous Barrier Function

iScience, 2020
Summary: The intestinal mucosa requires high levels of nucleotides for energy procurement, proliferation, and innate immunity. This need for nucleotide substrates substantially increases during injury, infection, and wound healing. In the present studies,

One-carbon metabolism in cancer [PDF]

, 2017
Cells require one-carbon units for nucleotide synthesis, methylation and reductive metabolism, and these pathways support the high proliferative rate of cancer cells.

The Intersection of Purine and Mitochondrial Metabolism in Cancer

Cells, 2021
Nucleotides are essential to cell growth and survival, providing cells with building blocks for DNA and RNA, energy carriers, and cofactors. Mitochondria have a critical role in the production of intracellular ATP and participate in the generation of ...

Ectonucleotidases in Acute and Chronic Inflammation

Frontiers in Pharmacology, 2021
Ectonucleotidases are extracellular enzymes with a pivotal role in inflammation that hydrolyse extracellular purine and pyrimidine nucleotides, e.g., ATP, UTP, ADP, UDP, AMP and NAD+. Ectonucleotidases, expressed by virtually all cell types, immune cells

Crystalizing the genetic code

, 2000
New developments are presented in the framework of the model introduced by the authors in refs. [1,2] and in which nucleotides as well as codons are classified in crystal bases of the quantum group U_q(sl(2)+sl(2)) in the limit q -> 0.

Analysis of substrate specificity and kinetics of cyclic nucleotide phosphodiesterases with N'-methylanthraniloyl-substituted purine and pyrimidine 3',5'-cyclic nucleotides by fluorescence spectrometry.

PLoS ONE, 2013
As second messengers, the cyclic purine nucleotides adenosine 3',5'-cyclic monophosphate (cAMP) and guanosine 3',5'-cyclic monophosphate (cGMP) play an essential role in intracellular signaling.

Co-therapy with S-adenosylmethionine and nicotinamide riboside improves t-cell survival and function in Arts Syndrome (PRPS1 deficiency)

Molecular Genetics and Metabolism Reports, 2021
Arts syndrome or phosphoribosyl-pyrophosphate-synthetase-1 (PRPS1) deficiency is caused by loss-of-function mutations in the PRPS1 gene (Xq22.3). PRPS1 is an initial and essential step for the synthesis of the nucleotides of purines, pyrimidines, and ...
