Waris, Muhammad Irfan published the artcileMolecular and in vitro biochemical assessment of chemosensory protein 10 from brown planthopper Nilaparvata lugens at acidic pH, Synthetic Route of 584-02-1, the main research area is mol in vitro biochem assessment chemosensory protein; Nilaparvata lugens acidic pH.

Chemosensory proteins (CSPs) are important mol. components of the insect olfactory system, which are involved in capturing, binding, and transporting hydrophobic odor mols. across the sensillum in sensillar lymph in regulating insect behavior. This protein family (CSPs) is also involved in many other systems that are not linked to olfactory receptors in olfactory sensilla. The brown planthopper (BPH) is a monophagous pest of rice that causes damage by sucking phloem sap and transmitting a number of diseases caused by viruses. In this study, fluorescence competitive binding assay and fluorescence quenching assay at acidic pH were performed as well as homol. modeling to describe the binding affinity of NlugCSP10. Fluorescence competitive binding assay (FCBA) demonstrated that NlugCSP10 bound strongly to nonadecane, farnesene, and 2-tridecanone at acidic pH. The results of FCBA indicated that NlugCSP10 bound different ligands at the physiol. pH (5.0) of the bulk sensillum lymph. Fluorescence quenching assay demonstrated that NlugCSP10 generated a stable complex with 2-tridecanone, while two ligands nonadecane and farnesene collided due to mol. collisions. The interaction of selected ligands with the modeled structure of NlugCSP10 was also analyzed, which found the key amino acids (Gln23, Gln24, Gln25, Asn27, Met33, Ser34, Ile35, Tyr36, Asn42, Met43, Val45, Asn46, Asn93, Arg96, Ala97, Lys99, and Ala100) in NlugCSP10 that were involved in binding of volatile compounds The present study contributes to the binding profile of NlugCSP10 that promotes the development of behaviorally active ligands based on BPH olfactory system.

Cheng, Tik-Chee published the artcileEstrogen receptor-α prevents right ventricular diastolic dysfunction and fibrosis in female rats, Safety of (S)-2-hydroxysuccinic acid, the main research area is estrogen receptor alpha ventricular diastolic dysfunction fibrosis mouse; adverse remodeling; estrogen receptor-α; pressure overload; right ventricle.

Although women are more susceptible to pulmonary arterial hypertension (PAH) than men, their right ventricular (RV) function is better preserved. Estrogen receptor-α (ERα) has been identified as a likely mediator for estrogen protection in the RV. However, the role of ERα in preserving RV function and remodeling during pressure overload remains poorly understood. We hypothesized that loss of functional ERα removes female protection from adverse remodeling and is permissive for the development of a maladapted RV phenotype. Male and female rats with a loss-of-function mutation in ERα (ERαMut) and wild-type (WT) littermates underwent RV pressure overload by pulmonary artery banding (PAB). At 10 wk post-PAB, WT and ERαMut demonstrated RV hypertrophy. Anal. of RV pressure waveforms demonstrated RV-pulmonary vascular uncoupling and diastolic dysfunction in female, but not male, ERαMut PAB rats. Similarly, female, but not male, ERαMut exhibited increased RV fibrosis, comprised primarily of thick collagen fibers. There was an increased protein expression ratio of TIMP metallopeptidase inhibitor 1 (Timp1) to matrix metalloproteinase 9 (Mmp9) in female ERαMut compared with WT PAB rats, suggesting less collagen degradation RNA-sequencing in female WT and ERαMut RV revealed kallikrein-related peptidase 10 (Klk10) and Jun Proto-Oncogene (Jun) as possible mediators of female RV protection during PAB. In summary, ERα in females is protective against RV-pulmonary vascular uncoupling, diastolic dysfunction, and fibrosis in response to pressure overload. ERα appears to be dispensable for RV adaptation in males. ERα may be a mediator of superior RV adaptation in female patients with PAH.

Liu, Youxia published the artcileComprehensive analysis of aberrantly expressed profiles of mRNA and its relationship with serum galactose-deficient IgA1 level in IgA nephropathy, COA of Formula: C6H12O6, the main research area is gene expression galactose IgA1 IgA nephropathy; Differential gene expression; Galactose-deficient IgA1; IgA nephropathy; RNA-deep sequencing; mRNA microarray.

IgA nephropathy (IgAN) is the leading cause of end-stage kidney disease. Previous mRNA microarray profiling studies of IgAN revealed inconsistent data. We sought to identify the aberrantly expressed genes and biol. pathways by integrating IgAN gene expression datasets in blood cells and performing systematically exptl. validation. We also explored the relationship between target genes and galactose-deficient IgA1 (Gd-IgA1) in IgAN. We retrieved Gene Expression Omnibus (GEO) datasets of IgAN. Gene Ontol. (GO) enrichment and Kyoto Encyclopedia of Genes and Genomes (KEGG) analyses were used for functional anal. Deep sequencing on RNA isolated from B cells was used for microarray validation. The relationship between target mRNA expressions and Gd-IgA1 levels in serum were also studied. Three studies with microarray expression profiling datasets met our inclusion criteria. We identified 655 dyregulated genes, including 319 up-regulated and 336 down-regulated genes in three GEO datasets with a total of 35 patients of IgAN and 19 healthy controls. Based on biol. process in GO term, these dyregulated genes are mainly related to pentose-phosphate shunt, non-oxidative branch, post-embryonic camera-type eye development and leukocyte activation. KEGG pathway anal. of microarray data revealed that these aberrantly expressed genes were enriched in human T-cell leukemia virus 1 infection, proteoglycans in cancer, intestinal immune network for IgA production and autophagy. We further performed deep sequencing on mRNAs isolated from B cells of an independent set of five patients with IgAN and three healthy persons with the same clin. and demog. characteristics. Seventy-seven genes overlapped with 655 differentially regulated genes mentioned above, including 43 up-regulated and thirty-four down-regulated genes. We next investigated whether these genes expression correlated with Gd-IgA1 levels in IgAN patients. Pearson correlation analyses showed PTEN (phosphatase and tensin homolog) was the most powerful gene neg. correlated with Gd-IgA1 levels. These results demonstrated that dyregulated genes in patients with IgAN were enriched in intestinal immune network for IgA production and autophagy process, and PTEN in B cells might be involved in the mechanism of Gd-IgA1 production

Tremblay-Laganiere, Camille published the artcilePolychlorinated biphenyl 126 exposure in rats alters skeletal muscle mitochondrial function, Formula: C4H6O5, the main research area is polychlorinated biphenyl skeletal muscle mitochondrial disease; Electron transport chain; Oxidative phosphorylation; Oxidative stress; Polychlorinated biphenyls; Skeletal muscle metabolism.

In the past few years, polychlorinated biphenyls (PCBs), a class of environmental pollutants, have been associated with metabolism dysregulation. Muscle is one of the key regulators of metabolism because of its mass and its important role in terms of glucose consumption and glucose storage. It has been shown that muscle alterations, such as oxidative stress and mitochondrial dysfunction, contribute significantly to the development of metabolic diseases. No study has yet investigated the toxicol. effect of PCBs on muscle mitochondrial function and oxidative stress in vivo. The aim of this study was to assess the effect of PCB126 in vivo exposure (single dose of 1.05 μmol/kg) on muscle mitochondrial function and oxidative stress in rats. PCB126-treated rats showed a marked increase in Cyp1a1 mRNA levels in skeletal muscles in association with a 40% reduction in state 3 oxygen consumption rate measured with complex I substrates in permeabilized muscle fibers. Furthermore, PCB126 exposure altered the expression of some enzymes involved in ROS detoxification such as catalase and glutaredoxin 2. Our results highlight for the first time a toxic effect of coplanar PCBs on skeletal muscle mitochondrial function and oxidative stress. This suggests that acute PCB exposure, by affecting muscle metabolism, could contribute to the development of metabolic disorders. Studies are needed to determine if lower-level but longer-term PCB exposure exhibits the same effect.

Savchenko, Tatyana V. published the artcileJasmonates-mediated rewiring of central metabolism regulates adaptive responses, Quality Control of 97-67-6, the main research area is review Arabidopsis jasmonate metabolism adaptive response plant growth; Adaptive responses; Allene oxide synthase; Central metabolism; Growth; Jasmonates; Resource allocation.

The lipid-derived hormones jasmonates (JAs) play key functions in a wide range of physiol. and developmental processes that regulate growth, secondary metabolism and defense against biotic and abiotic stresses. In this connection, biosynthesis, tissue-specific distribution, metabolism, perception, signaling of JAs have been the target of extensive studies. In recent years, the involvement of JAs signaling pathway in the regulation of growth and adaptive responses to environmental challenges has been further examined However, JAs-mediated mechanisms underlying the transition from ‘growth mode’ to ‘adaptive mode’ remain ambiguous. Combined anal. of transgenic lines deficient in JAs signaling in conjunction with the data from JAstreated plants revealed the function of these hormones in rewiring of centralmetabolism. The collective data illustrate JAs-mediated decrease in the levels of metabolites associated with active growth such as sucrose, raffinose, orotate, citrate, malate, and an increase in phosphorylated hexoses, responsible for the suppression of growth and photosynthesis, concurrent with the induction of protective metabolites, such as aromatic and branched-chain amino acids, and aspartate family of metabolites. This finding provides an insight into the function of JAs in shifting the central metabolism from the production of growth-promoting metabolites to protective compounds and expands our understanding of the role of JAs in resource allocation in response to environmental challenges.

Zhao, Yannan published the artcileMalate Circulation: Linking Chloroplast Metabolism to Mitochondrial ROS, Computed Properties of 97-67-6, the main research area is review Arabidopsis chloroplast NADH malate mitochondria reactive oxygen species; chloroplast-to-mitochondrion communication; malate circulation; malate valve; programmed cell death; reactive oxygen species; reducing power.

In photosynthetic cells, chloroplasts and mitochondria are the sites of the core redox reactions underpinning energy metabolism Such reactions generate reactive oxygen species (ROS) when oxygen is partially reduced. ROS signaling leads to responses by cells which enable them to adjust to changes in redox status. Recent studies in Arabidopsis thaliana reveal that chloroplast NADH can be used to generate malate which is exported to the mitochondrion where its oxidation regenerates NADH. Oxidation of this NADH produces mitochondrial ROS (mROS) which can activate signaling systems to modulate energy metabolism, and in certain cases can lead to programmed cell death (PCD). We propose the term ‘malate circulation’ to describe such redistribution of reducing equivalent to mediate energy homeostasis in the cell.

Voce, Sabrina published the artcileCompositional characterization of commercial sparkling wines from cv. Ribolla Gialla produced in Friuli Venezia Giulia, Application of 3-(Methylthio)propan-1-ol, the main research area is Ribolla Gialla sparkling wine terpene norisoprenoid lipid.

Ribolla Gialla (RG) is a white grape variety used in the production of high-quality sparkling wines. It is cultivated in a limited area between Friuli Venezia Giulia (FVG-Northeast Italy) and Slovenia; for this reason, there is little information about the composition and chem. characteristics of the sparkling wines produced. This work used different anal. approaches (FTIR spectroscopy, UHPLC-MS/MS, liquid-liquid extraction, SPE and SPME-GC-MS) to characterize thirty-three com. sparkling RG wines from different areas of FVG. The characteristics included the overall volatile profile and content of terpenes, C13-norisoprenoids, lipids, and metabolites of aromatic amino acids. The aroma profile of RG wines was mainly characterized by fermentative esters and β-damascenone, whereas other norisoprenoids and varietal aromas were below the odor threshold. Appreciable amounts of certain fatty acids were found (e.g., palmitic acid), which could be potentially correlated with greater foam stability. However, high concentrations of aromatic amino acids metabolites highlighted a higher risk of developing atypical aging defects.

Kang, Jingtian published the artcileControllable bistable smart composite structures driven by liquid crystal elastomer, Formula: C17H28O8S4, the main research area is liquid crystal elastomer smart composite simulation.

In this article, we proposed a new way to achieve monostable and bistable characteristics of composite layers based on liquid crystal elastomer (LCE). A smart trilayer composite structure is fabricated using LCE and acrylic elastomer, which can have several morphologies. It keeps flat at room temperature and can deform into a monostable saddle or bistable cylinder surface in response to simple temperature changes. The reversible deformation can be controlled through two parameters including geometrical size and actuation strain. The LCE can be programmed to generate different actuation strains by different formulas during synthesis or different mech. stretches during UV radiation. The deformed morphol. for different sample sizes and actuation strain is calculated using Finite element simulation. By comparison with the exptl. results, we confirm that the phenomena can be captured through numerical simulations. Furthermore, to have a quant. understanding, we use numerical simulation to calculate the deformation of the composite structure by tuning these two parameters and give a morphol. portrait illustrating the relationship between the deformed shape and control parameters.
