The phosphorylated pathway of serine biosynthesis links plant growth with nitrogen metabolism

2021

Abstract Because it is the precursor for various essential cellular components, the amino acid serine is indispensable for every living organism. In plants, serine is synthesized by two major pathways: photorespiration and the phosphorylated pathway of serine biosynthesis (PPSB). However, the importance of these pathways in providing serine for plant development is not fully understood. In this study, we examine the relative contributions of photorespiration and PPSB to providing serine for growth and metabolism in the C3 model plant Arabidopsis thaliana. Our analyses of cell proliferation and elongation reveal that PPSB-derived serine is indispensable for plant growth and its loss cannot b…

Hepatoprotective effects of extracts, fractions and compounds from the stem bark of Pentaclethra macrophylla Benth: Evidence from in vitro and in viv…

2021

Abstract Aim To identify the bioactive hepatoprotective components of the ethanol extract of Pentaclethra macrophylla stem bark using in vitro and in vivo approaches. Methods The bioguided-fractionation of the ethanol extract was based on the substances’ capacity to prevent in vitro, the lipid peroxidation of hepatocytes’ membranes induced by hydrogen peroxide. For the in vivo hepatoprotective test, mice were treated orally with the ethyl acetate (EtOAc) fraction of the ethanol extract at doses of 50 and 75 mg/kg/day for one week and subjected to d -galactosamine/lipopolysaccharide (GaIN/LPS)-induced hepatotoxicity. Blood samples were collected for alanine aminotransferase (ALAT), aspartate…

Association between Leptin and Complement in Hepatitis C Patients with Viral Clearance: Homeostasis of Metabolism and Immunity

2016

Background The association between leptin and complement in hepatitis C virus (HCV) infection remains unknown. Methods A prospective study was conducted including 474 (250 genotype 1, 224 genotype 2) consecutive chronic hepatitis C (CHC) patients who had completed an anti-HCV therapy course and undergone pre-therapy and 24-week post-therapy assessments of interferon λ3-rs12979860 and HCV RNA/genotypes, anthropometric measurements, metabolic and liver profiles, and complement component 3 (C3), C4, and leptin levels. Results Of the 474 patients, 395 had a sustained virological response (SVR). Pre-therapy leptin levels did not differ between patients with and without an SVR. Univariate and mul…

Oleoylethanolamide restores alcohol-induced inhibition of neuronal proliferation and microglial activity in striatum

2019

Previous findings demonstrate a homeostatic role for oleoylethanolamide (OEA) signaling in the ethanol-related neuroinflammation and behavior. However, extensive research is still required in order to unveil the effects of OEA on a number of neurobiological functions such as adult neurogenesis, cell survival and resident neuroimmunity that become notably altered by alcohol. Daily consumption of ethanol (10%) for 2 weeks (6.3& #x202F;± 1.1 g/kg/day during last 5 days) caused hypolocomotor activity in rats. This effect appears to rely on central signaling mechanisms given that alcohol increased the OEA levels, the gene expression of OEA-synthesizing enzyme Nape-pld and the number of PPARα-imm…

Structural Analysis of Phosphoserine Aminotransferase (Isoform 1) From Arabidopsis thaliana– the Enzyme Involved in the Phosphorylated Pathway of Ser…

2018

Phosphoserine aminotransferase (PSAT) is a pyridoxal 5'-phosphate (PLP)-dependent enzyme that catalyzes the conversion of 3-phosphohydroxypyruvate (3-PHP) to 3-phosphoserine (PSer) in an L-glutamate (Glu)-linked reversible transamination reaction. This process proceeds through a bimolecular ping-pong mechanism and in plants takes place in plastids. It is a part of the phosphorylated pathway of serine biosynthesis, one of three routes recognized in plant organisms that yield serine. In this three-step biotransformation, 3-phosphoglycerate (3-PGA) delivered from plastidial glycolysis and Calvin cycle is oxidized by 3-PGA dehydrogenase. Then, 3-PHP is subjected to transamination with Glu to yi…

Antibodies to hepatitis B core antigen in blood donors screened for alanine aminotransferase level and hepatitis non-A, non-B in recipients.

1988

Four-hundred and seventeen patients undergoing open-heart surgery were followed for more than 9 months after transfusion. All 2270 blood units transfused had alanine aminotransferase levels less than or equal to 30 U/l. Blood units positive for antibodies to hepatitis B core antigen (anti-HBc) were more frequently associated with recipient hepatitis non-A, non-B (HNANB) (13.7%) than anti-HBc-negative units (4.2%) (p less than 0.001). The frequency of HNANB among recipients of at least 1 anti-HBc-positive blood unit (8/79, 10.1%) was fivefold greater than among recipients of exclusively anti-HBc-negative blood units (7/338, 2.1%) (p less than 0.01). In this study the exclusion of donors posi…

Epidemiology and clinical features of Mediterranean spotted fever in Italy

2006

Mediterranean Spotted Fever is caused by Rickettsia conorii and is transmitted to humans by Rhipicephalus sanguineus, the common dog tick. It is characterized by the symptomatologic triad: fever, exanthema and "tache noire", the typical eschar at the site of the tick bite. In Italy the most affected region is Sicily. The seasonal peak of the disease (from June through September) occurs during maximal activity of immature stage ticks. Severe forms of the disease have been reported in 6% of patients, especially adults with one of the following conditions: diabetes, cardiac disease, chronic alcoholism, glucose-6-phosphate dehydrogenase deficiency, end stage kidney disease. The mortality rate m…
