Serine and glycine are biosynthetically linked, and together provide the essential precursors for the synthesis of proteins, nucleic acids, and lipids that are crucial to cancer cell growth. Moreover, serine/glycine biosynthesis also affects cellular antioxidative capacity, thus supporting tumour
Turnover parameters for plasma glycine were measured by administration of a single dose of [15N]glycine to overnight fasted healthy volunteers, nine patients with chronic leukaemia, one patient with acute monocytic leukaemia and one patient with chronic myeloid leukaemia before and after
BACKGROUND
Recent studies have revealed the antinociceptive effects of glycine transporter (GlyT) inhibitors in neuropathic pain models such as sciatic nerve-injured and diabetic animals. Bone cancer can cause the most severe pain according to complex mechanisms in which a neuropathic element is
Asparagine deamidation in peptides or in fibronectin fragments containing the asparagine-glycine-arginine sequence generates isoaspartate-glycine-arginine (isoDGR), a new alphavbeta3 integrin-binding motif. Because alphavbeta3 is expressed in angiogenic vessels, we hypothesized that
BACKGROUND
Glycine conjugation of mitochondrial acyl-CoAs, catalyzed by glycine N-acyltransferase (GLYAT, E.C. 2.3.1.13), is an important metabolic pathway responsible for maintaining adequate levels of free coenzyme A (CoASH). However, because of the small number of pharmaceutical drugs that are
Peptidoglycan polysaccharide (PG-PS) is a primary structural component of bacterial cell walls and causes rheumatoid-like arthritis in rats. Recently, glycine has been shown to be a potential immunomodulator; therefore, the purpose of this study was to determine if glycine would be protective in a
Accumulating lines of evidence suggest a possibility that glycine is useful as an immuno-modulating amino acid. Glycine most likely prevents the lipopolysaccharide (LPS)-induced elevation of intracellular Ca(2+) concentration in Kupffer cells, thereby minimizing LPS receptor signaling and cytokine
Neo-angiogenesis is important for tumor growth. Glycine is a non-toxic amino acid with suspected anti-angiogenic effects. This study was designed to evaluate anti-angiogenic effects of glycine in colorectal cancer. Glycine was added to cultures of human and rat colorectal cancer cells (CRC), and
In this study we investigated the effects of glycine on angiogenesis during embryogenesis, wound healing and tumor growth. In chorioallantoic membrane (CAM) assay, glycine (100 microM) inhibited angiogenesis by more than 50%. We studied dietary glycine's effect on fibrin induced wound healing
Expression patterns of proteins involved in serine and glycine metabolism, and correlations of these patterns with clinicopathologic factors in phyllodes tumor were investigated. Tissue microarrays were prepared from 203 phyllodes tumors (PT) and stained with antibodies specific for glycine
Metabolic pathways leading to the synthesis, uptake, and usage of the nonessential amino acid serine are frequently amplified in cancer. Serine encounters diverse fates in cancer cells, including being charged onto tRNAs for protein synthesis, providing head groups for sphingolipid and phospholipid
Resveratrol is found in grapes, red wine, and berries. Resveratrol has been known to have many beneficial health effects, such as anti-cancer, neuroprotective, anti-nociceptive, and life-prolonging effects. However, the single cellular mechanisms by which resveratrol acts are relatively unknown,
Glycine is involved in several physiological functions, e.g. as a neurotransmitter in the central nervous system, and sarcosine has been identified as a differential metabolite greatly enhanced during prostate cancer progression and metastasis. Glycine oxidase from Bacillus subtilis (GO) was
This study reports in vivo MRS findings in 11 patients with histologically diagnosed central neurocytomas, which are rare intraventricular tumors of neuronal origin. Single-voxel (1)H MRS was carried out prior to surgery using a point-resolved spectroscopy sequence with TR=6 s, TE=135 ms and 128
