Nucleotides play an important role in the regulation of cellular energy and protein homeostasis, which facilitate the repair, recovery, and repletion of tissue function. This study tested the effects of maternal uridine (UR) supplementation during late pregnancy and lactation of sows Diarrhoeal disease kills about 1.5 million human beings per year across the continents. The enterotoxigenic Escherichia coli (ETEC) pathotype has been noted as a major cause of diarrheal disease in human and livestock. The aim of this study is to identify broad-spectrum molecular targets in
Effects of oral administrations of uridine were investigated in a study of six healthy volunteer control subjects and nine patients with metastatic colorectal cancer. Oral uridine was studied as single-dose administrations at doses escalating from 0.3 to 12 g/m2 and as multiple-dose administrations
BACKGROUND
Previous preclinical and clinical investigations have shown that the combined administration of 5-fluorouracil (5-FU) with delayed uridine can reverse side effects induced by 5-FU. This biochemical modulation-based combination may increase the therapeutic index of 5-FU.
METHODS
Seven
BACKGROUND
In a previous trial in which methotrexate and N-phosphonacetyl-L-aspartate (PALA) were used to modulate 5-fluorouracil (5-FU), four of six patients could not tolerate treatment at the 600 mg/m2 5-FU dose level because of mucositis, diarrhea, and a decrease in performance status. The
OBJECTIVE
5-fluorouracil (5-FU) has been broadly used to treat solid tumors for more than 50 years. One of the major side effects of fluoropyrimidines therapy is oral and intestinal mucositis. Human uridine phosphorylase (hUP) inhibitors have been suggested as modulators of 5-FU toxicity. Therefore,
BACKGROUND
Uridine diphosphate glucuronosyltransferase (UGT) 1A1 7/7 polymorphism has been linked with an increased risk of irinotecan-induced severe toxicities. We evaluated UGT1A1 polymorphism in patients developing grade 3/4 toxicity after initiation of irinotecan to determine the frequency of
Pharmacogenetic research indicates a relationship between a polymorphism in the gene encoding uridine diphosphate glucuronosyltransferase 1A1 (UGT1A1) and irinotecan inactivation, in that degradation of SN-38, the active metabolite of irinotecan, correlates inversely with the number of TA repeats in
RNA extracted from isopycnically banded [3-H]uridine-labeled bovine viral diarrhea virus with sodium dodecyl sulfate was resolved into one major and two minor components by both sedimentation analysis and electrophoresis in polyacrylamide gels. The major RNA component was estimated to have a 38S
Uridine diphosphate glucuronosyltransferase 1A (UGT1A1), which affects irinotecan metabolism, has been associated with severe adverse reactions in patients with cancer treated with irinotecan. However, neither large-scale analysis of the distribution of UGT1A1 polymorphisms, nor standardized
Irinotecan (CPT-11) is used for therapy of various cancers. However, it has several serious adverse reactions such as diarrhea which is caused by SN-38, the active form of CPT-11. This study aimed to evaluate the effectiveness of Jiawei xianglian decoction (JWXLD), which has been widely used for the
Malarial parasites, in contrast to mammalian cells, utilize orotic acid more efficiently than uracil or uridine. Recently, chloroquine-susceptible and chloroquine-resistant clones of Plasmodium falciparum were shown to be inhibited by 5-fluoroorotate, with a 50% inhibitory concentration of 6 nM in
BACKGROUND
Lipoatrophy is prevalent on thymidine nucleoside reverse transcriptase inhibitors (tNRTIs). A pilot trial showed that uridine (NucleomaxX) increased limb fat.
METHODS
A5229 was a multicenter trial in which HIV-infected individuals with lipoatrophy on tNRTI regimens were randomized to
In vitro studies of certain lymphoid tumor cells show potentiation of 1-beta-D-arabinofuranosylcytosine (ara-C) effects by uridine because it elevates intracellular uridine triphosphate, resulting in increased ara-C triphosphate levels. Seven-day continuous i.v. infusions of uridine at 123 mg/kg/h
