Title: Effects of Trehalose on Pressure-Induced Inactivation of Yeast Alcohol Dehydrogenase. VOLUME: 12 ISSUE: 6. Author(s):Hyun Park, Gene Kidman and Dexter B. Northrop. Affiliation:Center for Drug Evaluation Division of Pharmaceutical Sciences, School of Pharmacy, University ofWisconsin-Madison, Madison, WI 53705, U.S.A.. Keywords:yeast alcohol dehydrogenase, trehalose, hydrostatic pressure, protein denaturation, barostability, thermostability, surface tension. Abstract: Isozymes of yeast alcohol dehydrogenase are slowly denatured at moderate hydrostatic pressures ( < 3 kbar). The time courses for inactivation are biphasic and both phases of both isozymes are protected by trehalose. ADH-I is slightly more barostable than ADH-II which is opposite to their thermostabilities. Trehalose at 1M extends their halflives about 6-fold at 2 kbar, pH 7.5 and 25°C. In contrast, 1M sucrose provides only 4.4-fold protection under identical conditions, a finding consistent with the superior protein ...
Recently, high concentrations of intracellular trehalose (>200mM) were employed to enhance the cryoprotection and desiccation protection of human erythrocytes. However, significant challenges must be overcome if this advancement is to be translated into clinical practice. It is here demonstrated that 247 ± 5 mM intracellular trehalose caused the lysis of 60 ± 2% of erythrocytes upon resuspension in PBS of physiological osmolality (300 mOsm) and caused surviving cells to swell up to 140 ± 2% of isotonic cell volume. Trehalose loaded cells also exhibited 24 ± 1% incidence of phosphatidylserine translocation upon resuspension in 300 mOsm PBS, likely due to loading induced cell swelling. Un-loading of trehalose from erythrocytes using the membrane-permeabilizing biopolymer PP-50 was investigated as a technique to mitigate these damaging effects. After erythrocyte un-loading from 247 ± 5 mM to 39 ± 2 mM intracellular trehalose, cell lysis at 300 mOsm PBS was reduced from 60 ± 2% to 17 ± 3%. ...
Trehalose is a non-reducing disaccharide formed by two glucose molecules. It is widely distributed in Nature and has been isolated from certain species of bacteria, fungi, invertebrates and plants, which are capable of surviving in a dehydrated state for months or years and subsequently being revived after a few hours of being in contact with water. This disaccharide has many biotechnological applications, as its physicochemical properties allow it to be used to preserve foods, enzymes, vaccines, cells etc., in a dehydrated state at room temperature. One of the most striking findings a decade ago was the discovery of the genes involved in trehalose biosynthesis, present in a great number of organisms that do not accumulate trehalose to significant levels. In plants, this disaccharide has diverse functions and plays an essential role in various stages of development, for example in the formation of the embryo and in flowering. Trehalose also appears to be involved in the regulation of carbon metabolism
Organisms ranging from bacteria, yeast, fungi, insects, invertebrates, and lower and higher plants have enzymes that can make trehalose.[5] In nature, trehalose can be found in plants, and microorganisms. In animals, trehalose is prevalent in shrimp, and also in insects, including grasshoppers, locusts, butterflies, and bees, in which trehalose serves as blood-sugar. Trehalose is then broken down into glucose by the catabolic enzyme trehalase for use. Trehalose is also present in the nutrition exchange liquid of hornets and their larvae.[citation needed]. Trehalose is the major carbohydrate energy storage molecule used by insects for flight. One possible reason for this is that the glycosidic linkage of trehalose, when acted upon by an insect trehalase, releases two molecules of glucose, which is required for the rapid energy requirements of flight. This is double the efficiency of glucose release from the storage polymer starch, for which cleavage of one glycosidic linkage releases only one ...

Trehalose is a disaccharide of glucose found in diverse organisms and is suggested to act as a stress protectant against heat, cold, desiccation, anoxia, and oxidation. Here, we demonstrate that treatment of [nematode worms of the species] Caenorhabditis elegans with trehalose starting from the young-adult stage extended the mean life span by over 30% without any side effects. Surprisingly, trehalose treatment starting even from the old-adult stage shortly thereafter retarded the age-associated decline in survivorship and extended the remaining life span by 60%. Demographic analyses of age-specific mortality rates revealed that trehalose extended the life span by lowering age-independent vulnerability. Moreover, trehalose increased the reproductive span and retarded the age-associated decrease in pharyngeal-pumping rate and the accumulation of lipofuscin.. .... The life span-extending effect of trehalose was abolished in long-lived insulin/IGF-1-like receptor (daf-2) mutants. ... These findings ...
White, odorless, sweet-tasting powder. Trehalose is a disaccharide, two simple sugars in one molecule. In trehalose (as in maltose), the two sugars are both glucose. Trehalose, like maltose, is 45% as sweet as sugar. It does not brown like sugar, and has a very low hygroscopicity (moisture attraction), so it stays free-flowing and dry. In trehalose, one glucose molecule is upside-down relative to the other. In maltose, the two glucose molecules are in the same orientation. This small difference reflects in the properties of trehalose. It does not brown when heated, it does not promote bacterial growth or tooth decay as much as maltose or sugar, and it is less attractive to moisture. Trehalose is found in honey, breads, beer, and seafood. ...

Trehalose is an unusual non-reducing disaccharide that plays a variety of biological roles, from food storage to cellular protection from environmental stresses such as desiccation, pressure, heat-shock, extreme cold, and oxygen radicals. It is also an integral component of the cell-wall glycolipids of mycobacteria. The primary enzymatic route to trehalose first involves the transfer of glucose from a UDP-glucose donor to glucose-6-phosphate to form alpha,alpha-1,1 trehalose-6-phosphate. This reaction, in which the configurations of two glycosidic bonds are set simultaneously, is catalyzed by the glycosyltransferase trehalose-6-phosphate synthase ( OtsA), which acts with retention of the anomeric configuration of the UDP-sugar donor. The classification of activated sugar-dependent glycosyltransferases into approximately 70 distinct families based upon amino acid sequence similarities places OtsA in glycosyltransferase family 20 (see afmb.cnrs-mrs.fr/CAZY/). The recent 2.4 Angstrom structure of ...

This natural sugar is used in the food industry as a preservative and flavor enhancer (its in Taco Bells meat filling). And curiously, medical researchers keep running into trehalose when theyre looking for ways to fight neurodegenerative diseases.. A recent example from Emorys Department of Pharmacology: Chris Holler, Thomas Kukar and colleagues were looking for drugs that might boost human cells production of progranulin (PGRN), a growth factor that keeps neurons healthy. Mutations in the progranulin gene are a common cause of frontotemporal dementia.. The Emory scientists discovered two leads: a class of compounds called mTOR inhibitors - the transplant drug rapamycin is one - and trehalose. The team decided to concentrate on trehalose because it increased PGRN levels in neuronal and non-neuronal cell types, unlike the mTOR inhibitors. Their results were published at the end of June in Molecular Neurodegeneration.. The team confirmed their findings by examining the effects of trehalose ...

Central carbon metabolism.Our data show that a large proportion of differentially expressed transcripts are related to core metabolic activities of the fermenting yeasts (Tables 1 and 2 and Fig. 4). Several enzymes involved in hexose metabolism, glycolysis, trehalose metabolism, and redox balance are differentially expressed between strains at various stages of fermentation. The analysis of the gene expression levels within the framework of enzyme-enzyme and enzyme-metabolite interaction graphs (using the reporter metabolite approach) helped to pinpoint areas of metabolism that could speculatively be related to strain-strain or time point variation.. Trehalose, glucose-6-phosphate, glucose, UDP-glucose, and fructose-6-phosphate scored high on the multiple analyses across time points during fermentation (Table 5). Indeed, these metabolites did show marked differences in concentration between time points (Fig. 5). Trehalose was also a prominent interstrain reporter for days 2 and 5 (Table 4), and ...

Oocyte cryopreservation is extremely beneficial for assisted reproductive technologies, the treatment of infertility and biotechnology and offers a viable alternative to embryo freezing and ovarian grafting approaches for the generation of embryonic stem cells and live offspring. It also offers the potential to store oocytes to rescue endangered species by somatic cell nuclear transfer and for the generation of embryonic stem cells to study development in these species. We vitrified mouse oocytes using a range of concentrations of trehalose (0 to 0.3 M) and demonstrated that 0.1 and 0.3 M trehalose had similar developmental rates, which were significantly different to the 0.2 M cohort (P , 0.05). As mitochondria are important for fertilisation outcome, we observed that the clustering and distribution of mitochondria of the 0.2 M cohort were more affected by vitifrication than the other groups. Nevertheless, all 3 cohorts were able to develop to blastocyst, following in vitro fertilisation, ...

Esimese täissünteetilise plastiku polüamiidi avastamisega 1930. aastatel algas plastikatööstuse revolutsioon. Polüamiidi teatakse paremini kui nailon. Harvardi teadlased, kes selle avastasid (tuntud ka kui Fibre66), olid katsetanud 12 aastat, keemiafirma DuPont aga investeerinud 27 miljonit dollarit eesmärgiga leiutada kunstsiid sukkade tootmiseks. Ja peagi olidki nailonsukad naiste seas ülipopulaarsed. Tänaseks toodetakse nailonist nii riideid, jalatseid, mänguasju kui muid tarbeid, mis peavad olema vastupidavad, vettpidavad ja kangalaadsed.. Siia esimese laine plastikute hulka kuulub ka polüstüreen (PS), mis toodeti esimesena 30. aastatel Berliinis ja polüvinüülkloriid (PVC), mis leiti 1872. aastal Saksamaal (1835 komistas selle otsa kogemata ka üks prantslane) , kuid läks tootmisesse alles 20. aastatel. Tuntud keemiafirma Dow Chemical avastas 54. aastal, et polüstüreeni saab paisutada ning nii leidis see kasutust hoonete soojustamisel, pakendamisel ja ühekordsete ...

Purpose : Tear lipid deficiency is common among dry eye patients, leading to rapid tear film evaporation and instability, with symptoms of discomfort and visual disturbance. This investigation tested the clinical performance of a novel eye drop containing lubricant polymers, osmoprotectants including the disaccharide trehalose, and emulsified flaxseed oil, a source of the omega-3 fatty acid alpha-linolenic acid. Methods : 242 dry eye subjects were enrolled in this multi-center, randomized, double-masked, controlled clinical trial. Subjects used either the novel eye drop containing flaxseed oil and trehalose (OM3) or a marketed lipid-containing eye drop (Refresh Optive® Advanced, ROA,). Both products were supplied in identical unit-dose vials, and subjects dosed as needed, at least 2X per day, for 90 days, following a 1-week run-in with a standard aqueous tear (Refresh Plus®). The primary outcome variable was the change from baseline in Ocular Surface Disease Index (OSDI) score at Day 90. Other ...
Trehalose (α-D-glucopyranosyl-α-D-glucopyranoside) is a non-reducing disaccharide present in fungi, algae and several invertebrate phyla such as nematodes, annelids and arthropods (see Elbein, 1974). In many insects, trehalose constitutes the major haemolymph (blood) sugar, whereas glucose is often present at much lower concentrations (for a review, see Wyatt, 1967; Becker et al., 1996). Trehalose is synthesized and released into the haemolymph by the fat body, the central organ of intermediary metabolism in insects (Candy and Kilby, 1959, 1961).. Trehalose is split into two glucose units by the enzyme trehalase (EC 3.2.1.28), which is present in many insect tissues (for a review, see Becker et al., 1996). In locusts, the enzyme has been found in thoracic ganglia (Strang and Clement, 1980), brain and skeletal muscle. Trehalase activity is very low in locust haemolymph, and it is doubtful whether this activity is due to a `true trehalase (Vaandrager et al., 1989). High activity has been found ...

While E. coli only synthesizes trehalose under conditions of high osmolarity, it can degrade the sugar under conditions of both low and high osmolarity. In fact, E. coli can grow with trehalose as the sole carbon source. Different pathways are employed under different osmolarity conditions. Under high osmotic conditions the bacterium synthesizes large amounts of trehalose, which is used as an osmoprotectant [ Giaever88 ]. Trehalose molecules that leak from the cytoplasm into the periplasm can be recycled by the action of the TreA, a periplasmic trehalase. TreA breaks trehalose into two glucose molecules, which are then recycled by transport back into the cytoplasm through the glucose PTS [ Styrvold91 ]. Another function of TreA is the utilization of external trehalose under conditions of high osmolarity [ Boos87 ]. A second trehalase, which is cytoplasmic (encoded by the treF gene), is active during the transition period between high and low osmolarity. As the cells are shifting their metabolism ...

It can cause swollen liver, liver cancer and liver failure. It is believed to develop when the liver works to process dietary sugar and fructose --- particularly those found in high-fructose sugars in soft drinks and processed food. Unlike artificial sugars, trehalose is a natural sugar found in plants and insects which is approved by the FDA for human consumption. Doctors from St. Louis Childrens Hospital in Missouri found that the mice that develop fatty livers in response to a high-fructose diet have a protein on the surface of their liver cells -- the protein is named GLUT8. Researchers directed their efforts at blocking the GLUT8. They decided to test trehalose. For the study, they fed mice a combination of ahigh-fructose diet and drinking water that contained 3% trehalose. The results? Trehalose completely blocked the development of a fatty liver. Additionally, the mice had a lower body weight while and cholesterol levels, fatty acids and triglycerides were all reduced! Mushrooms, ...
