An Intermediary Role of Adenine Nucleotides on Free Fatty Acids-Induced Hyperglycemia in Obese Mice

Frontiers in Endocrinology, 2019
Increased plasma free fatty acids (FFA) level plays a central role in the development of type 2 diabetes. Our previous studies have shown that plasma 5′-adenosine monophosphate (5′-AMP) elevates and acts as a potential upstream regulator of hyperglycemia

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,

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

A crystal base for the genetic code [PDF]

, 1998
The quantum enveloping algebra U_q(sl(2) \oplus sl(2)) in the limit q \to 0 is proposed as a symmetry algebra for the genetic code. In this approach the triplets of nucleotids or codons in the DNA chain are classified in crystal bases, tensor product of ...

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.

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.
