LTPs play a role in several biological processes, including the root nodule symbiosis. In this regard, the Medicago truncatula nodulin 5 (MtN5) LTP has been proved to positively regulate the nodulation capacity, controlling rhizobial infection and nodule primordia invasion. To better define the lipid transfer protein MtN5 function during the symbiosis, we produced MtN5-downregulated and -overexpressing plants, and we analysed the transcriptomic changes occurring in the roots at an early stage of Sinorhizobium meliloti infection. We also carried out the lipid profile analysis of wild type (WT) and MtN5-overexpressing roots after rhizobia infection. The downregulation of MtN5 increased the root hair curling, an early event of rhizobia infection, and concomitantly induced changes in the expression of defence-related genes. -

The Janus-Like Role of Proline Metabolism in Cancer Lynsey Burke1,Innaguterman1, Raquel Palacios Gallego1, Robert G

Britton1, Daniel Burschowsky2, Cristina Tufarelli1 and Alessandro Rufini1 Abstract The metabolism of the non-essential amino acid L-proline is emerging as a key pathway in the metabolic rewiring that sustains cancer cells proliferation, survival and metastatic spread. Pyrroline-5-carboxylate reductase (PYCR) and proline dehydrogenase (PRODH) enzymes, which catalyze the last step in proline biosynthesis and the first step of its catabolism, respectively, have been extensively associated with the progression of several malignancies, and have been exposed as potential targets for anticancer drug development. As investigations into the links between proline metabolism and cancer accumulate, the complexity, and sometimes contradictory nature of this interaction emerge. It is clear that the role of proline metabolism enzymes in cancer depends on tumor type, with different cancers and cancer-related phenotypes displaying different dependencies on these enzymes. Unexpectedly, the outcome of rewiring proline metabolism also differs between conditions of nutrient and oxygen limitation. Here, we provide a comprehensive review of proline metabolism in cancer; we collate the experimental evidence that links proline metabolism with the different aspects of cancer progression and critically discuss the potential mechanisms involved. ● How is the rewiring of proline metabolism regulated Facts depending on cancer type and cancer subtype? 1234567890():,; 1234567890():,; 1234567890():,; 1234567890():,; ● Is it possible to develop successful pharmacological ● Proline metabolism is widely rewired during cancer inhibitor of proline metabolism enzymes for development. -

Reduction of Pectinesterase Activity in a Commercial Enzyme Preparation
Journal of the Science of Food and Agriculture J Sci Food Agric 85:1613–1621 (2005) DOI: 10.1002/jsfa.2154 Reduction of pectinesterase activity in a commercial enzyme preparation by pulsed electric fields: comparison of inactivation kinetic models Joaquın´ Giner, Pascal Grouberman, Vicente Gimeno and Olga Martın´ ∗ Department of Food Technology, University of Lleida, CeRTA-UTPV, ETSEA, Avda Alcalde Rovira Roure 191, 25198-Lleida, Spain Abstract: The inactivation of pectinesterase (PE) in a commercial enzyme preparation (CEP) under high intensity pulsed electric fields (HIPEF) was studied. After desalting and water dilution of the raw CEP, samples were exposed to exponentially decay waveform pulses for up to 463 µs at electric field intensities ranging from 19 to 38 kV cm−1. Pulses were applied in monopolar mode. Experimental data were fitted to a first-order kinetic model as well as to models based on Fermi, Hulsheger¨ or Weibull equations to describe PE inactivation kinetics. Characteristic parameters for each model were calculated. Relationships between some of the parameters and process variables were obtained. The Weibull model yielded the best accuracy factor. The relationship between residual PE and input of electrical energy density was found to be that of exponential decay. 2005 Society of Chemical Industry Keywords: pulsed electric fields; kinetics; pectinesterase; model; inactivation INTRODUCTION It has become customary to use CEPs in fruit and Pectinesterase (PE; EC 3.1.1.11) is a pectic enzyme vegetable juice technology.

Supplemental Methods
Supplemental Methods: Sample Collection Duplicate surface samples were collected from the Amazon River plume aboard the R/V Knorr in June 2010 (4 52.71’N, 51 21.59’W) during a period of high river discharge. The collection site (Station 10, 4° 52.71’N, 51° 21.59’W; S = 21.0; T = 29.6°C), located ~ 500 Km to the north of the Amazon River mouth, was characterized by the presence of coastal diatoms in the top 8 m of the water column. Sampling was conducted between 0700 and 0900 local time by gently impeller pumping (modified Rule 1800 submersible sump pump) surface water through 10 m of tygon tubing (3 cm) to the ship's deck where it then flowed through a 156 µm mesh into 20 L carboys. In the lab, cells were partitioned into two size fractions by sequential filtration (using a Masterflex peristaltic pump) of the pre-filtered seawater through a 2.0 µm pore-size, 142 mm diameter polycarbonate (PCTE) membrane filter (Sterlitech Corporation, Kent, CWA) and a 0.22 µm pore-size, 142 mm diameter Supor membrane filter (Pall, Port Washington, NY). Metagenomic and non-selective metatranscriptomic analyses were conducted on both pore-size filters; poly(A)-selected (eukaryote-dominated) metatranscriptomic analyses were conducted only on the larger pore-size filter (2.0 µm pore-size). All filters were immediately submerged in RNAlater (Applied Biosystems, Austin, TX) in sterile 50 mL conical tubes, incubated at room temperature overnight and then stored at -80oC until extraction. Filtration and stabilization of each sample was completed within 30 min of water collection. -

The association between egg contamination and foodborne outbreaks of SE suggests egg derived SE might be more adept to cause human illness than SE from other sources. Therefore, there is a need to understand the molecular mechanisms underlying the ability of egg- derived SE to colonize the chicken intestinal and reproductive tracts and cause disease in the human host. To this end, the present study was carried out in three objectives. The first objective was to sequence two egg-derived SE isolates belonging to the PFGE type JEGX01.0004 to identify the genes that might be involved in SE colonization and/or pathogenesis. -
Sunlight-Driven Environmental Benign Production of Bioactive Natural Products with Focus on Diterpenoids and the Pathways Involved in Their Formation
Natural Products: source of INNovatIoN CHIMIA 2017, 71, No. 12 851 doi:10.2533/chimia.2017.851 Chimia 71 (2017) 851–858 © Swiss Chemical Society Sunlight-driven Environmental Benign Production of Bioactive Natural Products with Focus on Diterpenoids and the Pathways Involved in their Formation Dan Luo, Birger Lindberg Møller, and Irini Pateraki* Abstract: Diterpenoids are high value compounds characterized by high structural complexity. They constitute the largest class of specialized metabolites produced by plants. Diterpenoids are flexible molecules able to engage in specific binding to drug targets like receptors and transporters. In this review we provide an account on how the complex pathways for diterpenoids may be elucidated. Following plant pathway discovery, the com- pounds may be produced in heterologous hosts like yeasts and E. coli. Environmentally contained production in photosynthetic cells like cyanobacteria, green algae or mosses are envisioned as the ultimate future production system.
