The regulation of glucuronidation during hypoxia was studied in isolated hepatocytes by analysing the dependence of acetaminophen glucuronidation rate on the intracellular concentrations of UTP, glucose 1-phosphate, UDP-glucose and UDP-glucuronic acid. The steady-state concentrations of these
The effect of (-)eburnamonine, papaverine and UDP-glucose intracarotid perfusion has been evaluated in the brain of beagle dogs during various conditions of cerebral damage (hypoxia, hypoxia plus incomplete ischaemia, hypoxia plus complete ischaemia), and after 3, 15 or 30 min of the post-hypoxic
UDP-glucose dehydrogenase (UGDH) is a key enzyme of the unique pathway for the synthesis of UDP-glucuronate, the substrate for the numerous glucuronosyl transferases, which act on the synthesis of glycosaminoglycans and glucuronidation reaction of xeno- and endobiotics. Using the bacterial
OBJECTIVE
To evaluate pathologically the effect of the single or combined application of UDP-glucose, GDNF and memantine on the improvement of white matter injury in neonatal rats with periventricular leukomalacia (PVL) under light and electron microscopy.
METHODS
A five-day-old neonatal rat model
Periventricular leukomalacia (PVL) is one of the foremost neurological conditions leading to long-term abnormalities in premature infants. Since it is difficult to prevent initiation of this damage in utero, promoting the innate regenerative potential of the brain after birth may provide a more
Waterlogging is one of the main abiotic stresses that limit wheat production. Quantitative proteomics analysis has been applied in the study of crop abiotic stress as an effective way in recent years (e.g. salt stress, drought stress, heat stress and waterlogging stress). However, only A low level of UDP-Glc occurs in cells exposed to hypoxia or glucose starvation. This work reveals that a 65% reduction in the cellular UDP-Glc level causes up-regulation of the mitochondrial chaperone GRP75 and the endoplasmic reticulum (ER) resident chaperones GRP58, ERp72, GRP78, GRP94, GRP170,
Trehalose is a nonreducing disaccharide in which the two glucose units are linked in an alpha,alpha-1,1-glycosidic linkage. The best known and most widely distributed pathway of trehalose synthesis involves the transfer of glucose from UDP-glucose to glucose 6-phosphate to form trehalose-6-phosphate
Fructose 2,6-bisphosphate (Fru-2,6-P2) is the most potent stimulator of 6-phosphofructo-1-kinase (PFK-1), a key enzyme of glycolysis. We studied whether this regulator is involved in the changes of glycolysis that can be induced experimentally in the isolated working rat heart. The glycolytic flux
The unidirectional steady state reaction rates of several enzymes and metabolic fluxes of distinct processes were measured simultaneously in hypoxic maize root tips using two-dimensional phosphorus NMR exchange spectroscopy. A single spectrum monitors ATP synthesis and hydrolysis as well as the
The behaviour of fuels (glycogen, glucose), of glycolytic pathway intermediates (glucose-6-phosphate, pyruvate) and end-product (lactate), as well as the pool of labile phosphates (ATP, ADP, AMP, creatine phosphate) and the energy charge of the brain were studied in the motor area of the cerebral
Specific morphological and biochemical characteristics of seeds can cause oxygen deficiency within maternal and embryonic tissues. In this study, optical sensors were used to measure O(2) profiles across developing seeds of Vicia faba and Pisum sativum and developmental and environmental modulations
