Background and Objective: Serine and glycine are connecting lines for biosynthesis and are essential resources for synthesis of proteins, nucleic acids and lipids that are necessary for cancer cell growth. The purpose of this study was to set a comparison of serine and glycine in patients with esophageal cancer and in healthy people. Materials and Methods: 37 plasma samples were collected from...
Recent evidence suggests that a strychnine-insensitive glycine modulatory site is associated with the N-methyl-D-aspartate receptor-channel complex. A quantitative autoradiographic method was used to characterize the pharmacological specificity and anatomical distribution of strychnine-insensitive [3H]glycine binding sites in rat brain. [3H]Glycine binding was specific, saturable, reversible, p...
BACKGROUND The amino acid glycine, modulates neurotransmission via actions at GLY-A receptor and GLY-B receptor. The latter are coagonist sites associated with N-Methyl-D-Aspartate (NMDA) glutamate receptors. The central bioavailability of peripherally administered glycine has not been adequately characterized in humans. METHODS Healthy human subjects were administered either oral D-cycloseri...
The anticonvulsant effects of D-cycloserine, which is a partial agonist of the glycine/N-methyl-D-aspartate (NMDA) receptor, and L-701,324, which is a selective and potent antagonist that acts at the glycine site, were studied in electroshock-induced seizures in mice. Glycine, which is a natural full agonist that acts at the glycine site, enhanced the seizure threshold-increasing effect of D-cy...
Strychnine-sensitive glycine receptors and glycine-immunoreactive fibers are expressed in the hypothalamic paraventricular nucleus (PVN), yet the functional significance of this innervation is unclear. Therefore, these studies examined the changes in cardiovascular and renal function and renal sympathetic nerve activity (RSNA) produced by the microinjection of glycine (5 and 50 nmol) into the P...
Glycine, a nonessential amino-acid that acts as an inhibitory neurotransmitter in the central nervous system, is currently used as a dietary supplement to improve the quality of sleep, but its mechanism of action is poorly understood. We confirmed the effects of glycine on sleep/wakefulness behavior in mice when administered peripherally. Glycine administration increased non-rapid eye movement ...
Glycine is an important biomarker in clinical analysis due to its involvement multiple physiological processes. As such, the need for low-cost analytical tools glycine detection growing. a neurotransmitter, involved inhibitory and excitatory neurochemical transmission central nervous system. In this work, we present 10 μM Pt-based electrochemical enzymatic biosensor localized real time measurem...
Glycine prevents hepatic damage caused by hypoxia-reoxygenation, diminishes mortality due to endotoxin and minimizes alcoholic liver injury by decreasing blood ethanol. Our purpose was to investigate the effect of dietary glycine during recovery from early alcohol-induced injury, using a model that mimics the clinical presentation and histopathology with alcoholics. Male Wistar rats were expose...
The actions of glycine on the NMDA receptor-mediated synaptic responses of ganglion cells were studied in the tiger salamander retinal slice. Ganglion cell excitatory postsynaptic currents (EPSCs) were elicited either by exciting bipolar cells with potassium puffs or by light stimulation, and were measured using whole-cell patch-clamp techniques. Increasing bath glycine concentrations to 10 mic...
