Uridine-Ribohydrolase Is a Key Regulator in the Uridine Degradation Pathway of Arabidopsis   [PDF]

open access: yesThe Plant Cell, 2009
Abstract Nucleoside degradation and salvage are important metabolic pathways but hardly understood in plants. Recent work on human pathogenic protozoans like Leishmania and Trypanosoma substantiates an essential function of nucleosidase activity.

From Formamide to RNA, the Path Is Tenuous but Continuous

open access: yesLife, 2015
Reactions of formamide (NH2COH) in the presence of catalysts of both terrestrial and meteoritic origin yield, in plausible and variegated conditions, a large panel of precursors of (pre)genetic and (pre)metabolic interest. Formamide chemistry potentially

Improvement of uridine production of Bacillus subtilis by atmospheric and room temperature plasma mutagenesis and high-throughput screening

open access: yesPLoS ONE, 2017
In the present study, a novel breeding strategy of atmospheric and room temperature plasma (ARTP) mutagenesis was used to improve the uridine production of engineered Bacillus subtilis TD12np. A high-throughput screening method was established using both

mRNA Expression and Activity of Nucleoside Transporters in Human Hepatoma HepaRG Cells

open access: yesPharmaceutics, 2018
The HepaRG cell line is a highly differentiated human hepatoma cell line, displaying the expression of various drug transporters. However, functional expression of nucleoside transporters remains poorly characterized in HepaRG cells, although these ...

Metabolomics profiles delineate uridine deficiency contributes to mitochondria-mediated apoptosis induced by celastrol in human acute promyelocytic leukemia cells

open access: yesOncoTarget, 2016
Celastrol, extracted from “Thunder of God Vine”, is a promising anti-cancer natural product. However, its effect on acute promyelocytic leukemia (APL) and underlying molecular mechanism are poorly understood.

Chemical Oxidation of Uridine Diphosphate-Glucose to Uridine Diphosphate-Glucuronic Acid [PDF]

open access: yesNature, 1961
THE importance of uronic acids in carbohydrate metabolism has only recently begun to be elucidated. The metabolism of inositol and ascorbate is known to involve uronic acid intermediates1,2, and nucleotide-bound glucuronic acid has been implicated in hyaluronic acid synthesis3.

The role of wobble uridine modifications in +1 translational frameshifting in eukaryotes

open access: yesNucleic Acids Research, 2015
In Saccharomyces cerevisiae, 11 out of 42 tRNA species contain 5-methoxycarbonylmethyl-2-thiouridine (mcm5s2U), 5-methoxycarbonylmethyluridine (mcm5U), 5-carbamoylmethyluridine (ncm5U) or 5-carbamoylmethyl-2′-O-methyluridine (ncm5Um) nucleosides in the ...

Compartmentalization of Uridine and Uridine 5′-Monophosphate in Rat Liver Slices

open access: yesJournal of Biological Chemistry, 1973
Abstract The metabolism of exogenous uridine, uridine 5'-monophosphate, and uracil by rat liver slices was studied using in vitro superfusion systems. Mixtures of 3H- and 14C-labeled uridine, uridine 5'-monophosphate, uracil, and orotic acid were superfused at a constant rate until an isotopic steady state was achieved.

Local Treatment of Hand-Foot Syndrome with Uridine/Thymidine: In Vitro Appraisal on a Human Keratinocyte Cell Line HaCaT

open access: yesThe Scientific World Journal, 2012
5-fluorouracil (5-FU) is one of the most commonly used antineoplastic drugs in the anticancer therapy. The hand-foot (HF) syndrome (palmar-plantar erythrodysesthesia) is an adverse effect frequently related to long-term i.v. administration of 5-FU or its
