Disease-associated inosine misincorporation into RNA hinders translation
Failure to prevent accumulation of the non-canonical nucleotide inosine triphosphate (ITP) by inosine triphosphate pyrophosphatase (ITPase) during nucleotide synthesis results in misincorporation of inosine into RNA and can cause severe and fatal ...

Human subcutaneous fibroblasts (HSCF) challenged with inflammatory mediators release huge amounts of ATP, which rapidly generates adenosine. Given the nucleoside’s putative relevance in wound healing, dermal fibrosis, and myofascial pain, we ...

Inosine metabolism in the rat [PDF]
1. Uptake and subsequent metabolism of purine and ribose moieties was monitored after intravenous administration of doubly labelled inosine. 2. More than 95% was cleared from the plasma within 5 min, and 99% within 20 min. 3. Approx. 50% of the 160 mumol total was rapidly incorporated into liver and kidney.

A purinergic call to arms from dying brown adipocytes
Brown adipocytes react to temperature and nutritional challenges by ramping up their metabolism and generating heat. This adaptation to changes in the environment is crucial for defending organismal homeostasis, but is impaired in obesity and ...

Biosensor measurement of purine release from cerebellar cultures and slices [PDF]
We have previously described an action-potential and Ca2+-dependent form of adenosine release in the molecular layer of cerebellar slices. The most likely source of the adenosine is the parallel fibres, the axons of granule cells. Using microelectrode

Inosine as a Tool to Understand and Treat Central Nervous System Disorders: A Neglected Actor?
Since the 1970s, when ATP was identified as a co-transmitter in sympathetic and parasympathetic nerves, it and its active metabolite adenosine have been considered relevant signaling molecules in biological and pathological processes in the central ...

Purine Nucleoside Phosphorylase (PNP) is an enzyme involved in biosynthetic pathway of purine nucleosides. Purine nucleoside phosphorylase catalyzes the cleavage of the glycosidic bond of ribo- or deoxyribonucleosides to form the purine base and ...

Functional and genetic evidence that nucleoside transport is highly conserved in Leishmania species: Implications for pyrimidine-based chemotherapy [PDF]
Leishmania pyrimidine salvage is replete with opportunities for therapeutic intervention with enzyme inhibitors or antimetabolites. Their uptake into cells depends upon specific transporters; therefore it is essential to establish whether various ...
