- Abstract
Plant proteins that are secreted without a classical signal peptide leader sequence are termed leaderless secretory proteins (LSPs) and are implicated in both plant development and (a)biotic stress responses. In plant proteomics experimental workflows, identification of LSPs is hindered by the possibility of contamination from other subcellar compartments upon purification of the secretome. Applying machine learning algorithms to predict LSPs in plants is also challenging due to the rarity of experimentally validated examples for training purposes. This work attempts to address this issue by establishing criteria for identifying potential plant LSPs based on experimental observations and training random forest classifiers on the putative datasets. The resultant plant protein database LSPDB and bioinformatic prediction tools LSPpred and SPLpred are available at lsppred.lspdb.org. The LSPpred and SPLpred modules are internally validated on the training dataset, with false positives controlled at 5%, and are also able to classify the limited number of established plant LSPs (SPLpred (3/4, LSPpred 4/4). Until such time as a larger set of bona fide (independently experimentally validated) LSPs is established using imaging technologies (light/fluorescence/electron microscopy) to confirm sub-cellular location, these tools represent a bridging method for predicting and identifying plant putative LSPs for subsequent experimental validation.

- Abstract
SARS-CoV-2 is a type of coronavirus responsible for the international outbreak of respiratory illness termed COVID-19 that forced the World Health Organization to declare a pandemic infectious disease situation of international concern at the beginning of 2020. The need for a swift response against COVID-19 prompted to consider different sources to identify bioactive compounds that can be used as therapeutic agents, including available drugs and natural products. Accordingly, this work reports the results of a virtual screening process aimed at identifying antiviral natural product inhibitors of the SARS-CoV-2 Mpro viral protease. For this purpose, ca. 2000 compounds of the Selleck database of Natural Compounds were the subject of an ensemble docking process targeting the Mpro protease. Molecules that showed binding to most of the protein conformations were retained for a further step that involved the computation of the binding free energy of the ligand-Mpro complex along a molecular dynamics trajectory. The compounds that showed a smooth binding free energy behavior were selected for in vitro testing. From the resulting set of compounds, five compounds exhibited an antiviral profile, and they are disclosed in the present work.

- Abstract
The COVID-19 pandemic outbreak prompts an urgent need for efficient therapeutics, and repurposing of known drugs has been extensively used in an attempt to get to anti-SARS-CoV-2 agents in the shortest possible time. The glycoside rutin shows manifold pharmacological activities and, despite its use being limited by its poor solubility in water, it is the active principle of many pharmaceutical preparations. We herein report our in silico and experimental investigations of rutin as a SARS-CoV-2 Mpro inhibitor and of its water solubility improvement obtained by mixing it with l-arginine. Tests of the rutin/l-arginine mixture in a cellular model of SARS-CoV-2 infection highlighted that the mixture still suffers from unfavorable pharmacokinetic properties, but nonetheless, the results of this study suggest that rutin might be a good starting point for hit optimization.

- Abstract
Iron (Fe) and manganese (Mn) are two essential elements for plants that compete for the same uptake transporters and show conflicting interactions at the regulatory level. In order to understand the differential response to both metal deficiencies in plants, two proteomic techniques (two-dimensional gel electrophoresis and label-free shotgun) were used to study the proteome profiles of roots from tomato plants grown under Fe or Mn deficiency. A total of 119 proteins changing in relative abundance were confidently quantified and identified, including 35 and 91 in the cases of Fe deficiency and Mn deficiency, respectively, with 7 of them changing in both deficiencies. The identified proteins were categorized according to function, and GO-enrichment analysis was performed. Data showed that both deficiencies provoked a common and intense cell wall remodelling. However, the response observed for Fe and Mn deficiencies differed greatly in relation to oxidative stress, coumarin production, protein, nitrogen, and energy metabolism.

- Abstract
La propuesta de innovación educativa Flipped laboratorio clínico y biomédico aplica la metodología de aula invertida a las prácticas de laboratorio. Su aplicación ha supuesto un cambio en la manera de enseñar del docente, obteniendo mejoras en el aprendizaje de los alumnos, permitiendo un mayor aprovechamiento del tiempo en las sesiones experimentales y aumentando el control del grupo. En el desarrollo de la propuesta se describe el uso de videos explicativos de corta duración y la introducción de preguntas en los mismos para el trabajo más profundo de los contenidos teóricos relacionados con la práctica de laboratorio que se va a realizar. De este modo, se ha invertido la forma tradicional de entender la clase, transfiriendo los conceptos ligados a la explicación de contenidos al entorno fuera del aula. El trabajo previo realizado por parte de los alumnos les confiere capacidad de reflexión y favorece el aprendizaje autónomo del alumno. Finalmente, su puesta en práctica ha servido para afrontar nuevos retos de la profesión docente y necesidades de la sociedad actual derivadas de los protocolos COVID. Ha supuesto un análisis del contexto que rodea y condiciona el desempeño docente, así como una contribución en las actividades desarrollas en el centro, a través de la introducción de las TAC en la preparación previa de las prácticas de laboratorio y de la adaptación de la docencia a la situación de semipresencialidad.

- Abstract
The ability to custom-modify cell surface glycans holds great promise for treatment of a variety of diseases. We propose a glycomimetic ofl-fucose that markedly inhibits the creation of sLeXby FTVI and FTVII, but has no effect on creation of LeXby FTIX. Our findings thus indicate that selective suppression of sLex display can be achieved, and STD-NMR studies surprisingly reveal that the mimetic does not compete with GDP-fucose at the enzymatic binding site.

295 Pags.- Figs.- Tabls. Tesis presentada para optar al grado de Doctor por la Universidad de Zaragoza. Creative Commons License Attribution-NonCommercial-NoDerivatives 4.0 International (CC BY-NC-ND 4.0)., El objetivo general de esta Tesis Doctoral es incrementar el conocimiento existente acerca de los efectos que causan las deficiencias de Fe y Mn y la toxicidad por Mn en los proteomas vegetales implicados en la absorción y el transporte de estos nutrientes. Se pretende dibujar, con un enfoque proteómico, un mapa general de las alteraciones metabólicas producidas por ambos estreses nutricionales en las plantas. El estudio de estos procesos permitirá incrementar el conocimiento existente sobre la homeostasis de estos metales y así asentar las bases para mejorar la calidad y productividad de los cultivos, elaborar posibles estrategias de fitoremediación y desarrollar fertilizantes eficientes y respetuosos con el medio ambiente., Se plantean los siguientes objetivos específicos: 1. Describir la categorización funcional de los perfiles proteicos de los tres fluidos principales en plantas, fluido apoplástico y las savias de xilema y floema, considerando los estudios proteómicos recientemente publicados. 2. Caracterizar, usando técnicas de 2-DE, los perfiles proteicos del fluido apoplástico de remolacha (Beta vulgaris), tanto en plantas control como afectadas por deficiencia de Fe y, en las mismas plantas, tras el suministro de Fe a las raíces. 3. Caracterizar, mediante técnicas de “shotgun proteomics”, los cambios inducidos por las deficiencias de Fe y Mn en el perfil proteico de la savia de xilema de plantas de tomate (Solanum lycopersicum). 4. Caracterizar, mediante técnicas de 2-DE y “shotgun proteomics”, los efectos de la toxicidad de Mn sobre los perfiles proteicos de la raíz y de la savia de xilema de plantas de tomate (Solanum lycopersicum)., Los trabajos incluidos en esta Tesis Doctoral han sido financiados por los proyectos de investigación AGL2012-31988, AGL2013-42175-R y AGL2016-75226-R del Ministerio de Economía y Competitividad (MINECO), co-financiados con FEDER, y el Grupo Consolidado A03 de la Diputación General de Aragón.

- Abstract
El objetivo general de esta Tesis Doctoral es incrementar el conocimiento existente acerca de los efectos que causan las deficiencias de Fe y Mn y la toxicidad por Mn en los proteomas vegetales implicados en la absorción y el transporte de estos nutrientes. Se pretende dibujar, con un enfoque proteómico, un mapa general de las alteraciones metabólicas producidas por ambos estreses nutricionales en las plantas. El estudio de estos procesos permitirá incrementar el conocimiento existente sobre la homeostasis de estos metales y así asentar las bases para mejorar la calidad y productividad de los cultivos, elaborar posibles estrategias de fitoremediación y desarrollar fertilizantes eficientes y respetuosos con el medio ambiente., Se plantean los siguientes objetivos específicos: 1. Describir la categorización funcional de los perfiles proteicos de los tres fluidos principales en plantas, fluido apoplástico y las savias de xilema y floema, considerando los estudios proteómicos recientemente publicados. 2. Caracterizar, usando técnicas de 2-DE, los perfiles proteicos del fluido apoplástico de remolacha (Beta vulgaris), tanto en plantas control como afectadas por deficiencia de Fe y, en las mismas plantas, tras el suministro de Fe a las raíces. 3. Caracterizar, mediante técnicas de “shotgun proteomics”, los cambios inducidos por las deficiencias de Fe y Mn en el perfil proteico de la savia de xilema de plantas de tomate (Solanum lycopersicum). 4. Caracterizar, mediante técnicas de 2-DE y “shotgun proteomics”, los efectos de la toxicidad de Mn sobre los perfiles proteicos de la raíz y de la savia de xilema de plantas de tomate (Solanum lycopersicum).

- Abstract
The aim of this work was to assess the effects of manganese (Mn) toxicity on the proteome of tomato roots using two proteomic approaches, shotgun and two-dimensional electrophoresis. The shotgun approach yielded 367 reliable proteins, whereas the 2-DE approach detected 340 consistent spots. The 2-DE method found 54 proteins changing in relative abundance in the excess Mn treatment, whereas the shotgun detected changes in 118 proteins. Only 7% of the differential proteins were found by both methods, illustrating their complementary nature. Metabolic pathways most affected were protein metabolism, oxido-reductases and signaling. Results support that Mn toxicity alters the protein turnover and impairs energy production in roots, leading to changes in glycolysis, pyruvate metabolism, TCA and oxidative phosphorylation. Excess Mn also induced changes in peroxidases and hydrolases participating in cell wall lignification and suberization and activated plant defense mechanisms, with changes occurring via pathogenesis-related proteins as well as peroxidases. Finally, Mn toxicity elicited regulatory mechanisms and affected the abundance of root nutrient reservoir proteins. The overall analysis of the differential root proteome upon Mn toxicity suggests a general slowdown of metabolic activities, especially energy production, cell wall integrity and protein turnover, which occurs in parallel with increases in stress related proteins.

- Abstract
Metal toxicity is a common problem in crop species worldwide. Some metals are naturally toxic, whereas others such as manganese (Mn) are essential micro-nutrients for plant growth but can become toxic when in excess. Changes in the composition of the xylem sap, which is the main pathway for ion transport within the plant, is therefore vital to understanding the plant’s response(s) to metal toxicity. In this study we have assessed the effects of exposure of tomato roots to excess Mn on the protein profile of the xylem sap, using a shotgun proteomics approach. Plants were grown in nutrient solution using 4.6 and 300 µM MnCl2 as control and excess Mn treatments, respectively. This approach yielded 668 proteins reliably identified and quantified. Excess Mn caused statistically significant (at p ≤ 0.05) and biologically relevant changes in relative abundance (≥2-fold increases or ≥50% decreases) in 322 proteins, with 82% of them predicted to be secretory using three different prediction tools, with more decreasing than increasing (181 and 82, respectively), suggesting that this metal stress causes an overall deactivation of metabolic pathways. Processes most affected by excess Mn were in the oxido-reductase, polysaccharide and protein metabolism classes. Excess Mn induced changes in hydrolases and peroxidases involved in cell wall degradation and lignin formation, respectively, consistent with the existence of alterations in the cell wall. Protein turnover was also affected, as indicated by the decrease in proteolytic enzymes and protein synthesis-related proteins. Excess Mn modified the redox environment of the xylem sap, with changes in the abundance of oxido-reductase and defense protein classes indicating a stress scenario. Finally, results indicate that excess Mn decreased the amounts of proteins associated with several signaling pathways, including fasciclin-like arabinogalactan-proteins and lipids, as well as proteases, which may be involved in the release of sign

- Abstract
Polypeptide GalNAc-transferase T3 (GalNAc-T3) regulates fibroblast growth factor 23 (FGF23) by O-glycosylating Thr178 in a furin proprotein processing motif RHT178R↓S. FGF23 regulates phosphate homeostasis and deficiency in GALNT3 or FGF23 results in hyperphosphatemia and familial tumoral calcinosis. We explored the molecular mechanism for GalNAc-T3 glycosylation of FGF23 using engineered cell models and biophysical studies including kinetics, molecular dynamics and X-ray crystallography of GalNAc-T3 complexed to glycopeptide substrates. GalNAc-T3 uses a lectin domain mediated mechanism to glycosylate Thr178 requiring previous glycosylation at Thr171. Notably, Thr178 is a poor substrate site with limiting glycosylation due to substrate clashes leading to destabilization of the catalytic domain flexible loop. We suggest GalNAc-T3 specificity for FGF23 and its ability to control circulating levels of intact FGF23 is achieved by FGF23 being a poor substrate. GalNAc-T3’s structure further reveals the molecular bases for reported disease-causing mutations. Our findings provide an insight into how GalNAc-T isoenzymes achieve isoenzyme-specific nonredundant functions.

- Abstract
Background: Current efforts in the identification of new biomarkers are directed towards an accurate differentiation between benign and premalignant cysts. Thermal Liquid Biopsy (TLB) has been previously applied to inflammatory and tumor diseases and could offer an interesting point of view in this type of pathology. Methods: In this work, twenty patients (12 males and 8 females, average ages 62) diagnosed with a pancreatic cyst benign (10) and premalignant (10) cyst lesions were recruited, and biological samples were obtained during the endoscopic ultrasonography procedure. Results: Proteomic content of cyst liquid samples was studied and several common proteins in the different groups were identified. TLB cyst liquid profiles reflected protein content. Also, TLB serum score was able to discriminate between healthy and cysts patients (71% sensitivity and 98% specificity) and between benign and premalignant cysts (75% sensitivity and 67% specificity). Conclusions: TLB analysis of plasmatic serum sample, a quick, simple and non-invasive technique that can be easily implemented, reports valuable information on the observed pancreatic lesion. These preliminary results set the basis for a larger study to refine TLB serum score and move closer to the clinical application of TLB providing useful information to the gastroenterologist during patient diagnosis.

The phloem sap, xylem sap and apoplastic fluid play key roles in long and short distance transport of signals and nutrients, and act as a barrier against local and systemic pathogen infection. Among other components, these plant fluids contain proteins which are likely to be important players in their functionalities. However, detailed information about their proteomes is only starting to arise due to the difficulties inherent to the collection methods. This review compiles the proteomic information available to date in these three plant fluids, and compares the proteomes obtained in different plant species in order to shed light into conserved functions in each plant fluid. Inter-species comparisons indicate that all these fluids contain the protein machinery for self-maintenance and defense, including proteins related to cell wall metabolism, pathogen defense, proteolysis, and redox response. These analyses also revealed that proteins may play more relevant roles in signaling in the phloem sap and apoplastic fluid than in the xylem sap. A comparison of the proteomes of the three fluids indicates that although functional categories are somewhat similar, proteins involved are likely to be fluid-specific, except for a small group of proteins present in the three fluids, which may have a universal role, especially in cell wall maintenance and defense. This article is part of a Special Issue entitled: Plant Proteomics— a bridge between fundamental processes and crop production, edited by Dr. Hans-Peter Mock.

El Fe y el Mn están clasificados como micronutrientes que participan en funciones esenciales para el desarrollo y crecimiento de las plantas. El organismo no puede crecer sin un suministro adecuado de estos metales, pero por otro lado, si los niveles de exposición son demasiado elevados pueden resultar potencialmente tóxicos. El rango de concentraciones considerado fisiológico para los metales esenciales es muy estrecho y varía en función de la especie, el tejido y las condiciones de crecimiento. El conjunto de mecanismos implicados en el mantenimiento de los niveles adecuados de estos nutrientes es lo que se conoce como homeostasis. Desde un punto de vista fisiológico, la homeostasis de metales requiere la coordinación a nivel de toda la planta de los mecanismos de adquisición en la raíz, translocación a la parte aérea, almacenamiento y su posterior removilización a órganos sumidero. En la regulación de la homeostasis el sistema vascular juega un papel fundamental puesto que participa en la traslocación via xilema, en la removilización via floema y en la distribución y almacenamiento via apoplasto. Cuando este equilibrio se pierde, se producen pérdidas en la productividad causadas por disminuciones tanto en rendimiento como en la calidad de los cultivos que conllevan un alto impacto económico al generar productos con menor valor comercial y nutricional e incrementa los costes en el manejo del cultivo. La disponibilidad de ambos metales en la corteza terrestre depende del pH y las características redox del suelo, de forma que cuando el pH del suelo es elevado ambos metales se encuentran en formas con niveles de solubilidad mínimos que resultan difícilmente asimilables por las plantas. El 30% de los suelos cultivables presentan un pH elevado, indicando que la deficiencia de de estos metales resulta uno de los factores limitantes en el área mediterránea, en cultivos en el centro de Asia, el medio oeste de estados unidos o el sur de Australia. Por otro lado, en el caso del Mn, la cantidad del metal asimilable por las plantas aumenta considerablemente conforme el pH disminuye, de forma que en suelos con pH ácido puede llegar a resultar tóxico. Las actividades antropogénicas, como las actividades mineras y los residuos de incineración o de procesos industriales, han provocado el enriquecimiento en metales del medio ambiente, originándose una acumulación de 100 a 1.000 veces más alta en relación con su proporción natural en la corteza terrestre. La toxicidad de Mn supone un problema agronómico cada vez más común y es prevalentes en zonas del norte de Europa y Asia, el norte de EEUU y Canadá, gran parte de sudamérica o en algunas zonas de Australia. Aunque la información de la homeostasis en metales ha aumentado en los últimos años, todavía hay muchos interrogantes al respecto. Por ello, la proteómica puede resultar una herramienta muy útil a la hora de identificar y caracterizar nuevas proteínas que participan en la homeostasis de metales. El estrés por Fe ha sido más estudiado desde un punto de vista proteómico que el estrés por Mn. Los primeros estudios sobre Fe fueron en tejidos vegetales completos como la raíz y las hojas, y aún hoy en día los trabajos en estos tejidos son mayoritarios. En el caso del Mn, los trabajos publicados hasta el momento a nivel de proteoma se han centrado en plantas con características hiperacumuladoras o en estudios en hoja. Sin embargo, el análisis de subproteomas, entre los que se incluyen los fluidos de la planta, que resultan cruciales para el entendimiento de la homeostasis de estos metales, resultan todavía limitados. Con estos antecedentes el objetivo general de esta Tesis Doctoral ha sido incrementar el conocimiento existente acerca de los efectos que causan las deficiencias de Fe y Mn y la toxicidad por Mn en los proteomas vegetales implicados en la absorción (raíz) y el transporte (savias de xilema y floema y fluido apoplástico) de estos nutrientes mediante la aplicación de aproximaciones proteómicas. El uso de la proteómica diferencial en estos estreses y subproteomas puede proporcionar información sobre los procesos de adaptación de las plantas, así como apuntar hacia posibles estrategias para combatirlos. Además, el uso de técnicas de proteómica clásicas (2-DE) y avanzadas (“shotgun proteomics”) permite llevar a cabo la comparación entre técnicas y establecer las ventajas y limitaciones de ambas en el análisis de estos proteomas.

- Abstract
This article contains consolidated proteomic data obtained from xylem sap collected from tomato plants grown in Fe- and Mn-sufficient control, as well as Fe-deficient and Mn-deficient conditions. Data presented here cover proteins identified and quantified by shotgun proteomics and Progenesis LC-MS analyses: proteins identified with at least two peptides and showing changes statistically significant (ANOVA; p ≤ 0.05) and above a biologically relevant selected threshold (fold ≥ 2) between treatments are listed. The comparison between Fe-deficient, Mn-deficient and control xylem sap samples using a multivariate statistical data analysis (Principal Component Analysis, PCA) is also included. Data included in this article are discussed in depth in the research article entitled “Effects of Fe and Mn deficiencies on the protein profiles of tomato (Solanum lycopersicum) xylem sap as revealed by shotgun analyses” [1]. This dataset is made available to support the cited study as well to extend analyses at a later stage.

- Abstract
The aim of this work was to study the effects of Fe and Mn deficiencies on the xylem sap proteome of tomato using a shotgun proteomic approach, with the final goal of elucidating plant response mechanisms to these stresses. This approach yielded 643 proteins reliably identified and quantified with 70% of them predicted as secretory. Iron and Mn deficiencies caused statistically significant and biologically relevant abundance changes in 119 and 118 xylem sap proteins, respectively. In both deficiencies, metabolic pathways most affected were protein metabolism, stress/oxidoreductases and cell wall modifications. First, results suggest that Fe deficiency elicited more stress responses than Mn deficiency, based on the changes in oxidative and proteolytic enzymes. Second, both nutrient deficiencies affect the secondary cell wall metabolism, with changes in Fe deficiency occurring via peroxidase activity, and in Mn deficiency involving peroxidase, Cu-oxidase and fasciclin-like arabinogalactan proteins. Third, the primary cell wall metabolism was affected by both nutrient deficiencies, with changes following opposite directions as judged from the abundances of several glycoside-hydrolases with endo-glycolytic activities and pectin esterases. Fourth, signaling pathways via xylem involving CLE and/or lipids as well as changes in phosphorylation and N-glycosylation also play a role in the responses to these stresses. Biological significance In spite of being essential for the delivery of nutrients to the shoots, our knowledge of xylem responses to nutrient deficiencies is very limited. The present work applies a shotgun proteomic approach to unravel the effects of Fe and Mn deficiencies on the xylem sap proteome. Overall, Fe deficiency seems to elicit more stress in the xylem sap proteome than Mn deficiency, based on the changes measured in proteolytic and oxido-reductase proteins, whereas both nutrients exert modifications in the composition of the primary and secondary cell

- Abstract
Iron deficiency is a yield-limiting factor with major implications for crop production, especially in soils with high CaCO3. Because stems are essential for the delivery of nutrients to the shoots, the aim of this work was to study the effects of Fe deficiency on the stem proteome of Medicago truncatula. Two-dimensional electrophoresis separation of stem protein extracts resolved 276 consistent spots in the whole experiment. Iron deficiency in absence or presence of CaCO3 caused significant changes in relative abundance in 10 and 31 spots, respectively, and 80% of them were identified by mass spectrometry. Overall results indicate that Fe deficiency by itself has a mild effect on the stem proteome, whereas Fe deficiency in the presence of CaCO3 has a stronger impact and causes changes in a larger number of proteins, including increases in stress and protein metabolism related proteins not observed in the absence of CaCO3. Both treatments resulted in increases in cell wall related proteins, which were more intense in the presence of CaCO3. The increases induced by Fe-deficiency in the lignin per protein ratio and changes in the lignin monomer composition, assessed by pyrolysis-gas chromatography–mass spectrometry and microscopy, respectively, further support the existence of cell wall alterations. Biological significance: In spite of being essential for the delivery of nutrients to the shoots, our knowledge of stem responses to nutrient deficiencies is very limited. The present work applies 2-DE techniques to unravel the response of this understudied tissue to Fe deficiency. Proteomics data, complemented with mineral, lignin and microscopy analyses, indicate that stems respond to Fe deficiency by increasing stress and defense related proteins, probably in response of mineral and osmotic unbalances, and eliciting significant changes in cell wall composition. The changes observed are likely to ultimately affect solute transport and distribution to the leaves.

A comparison of the proteomes of the three fluids indicates that although functional categories are somewhat similar, proteins involved are likely to be fluid-specific, except for a small group of proteins present in the three fluids, which may have a universal role, especially in cell wall maintenance and defense.

- Abstract
El incremento del impacto humano sobre las aguas de nuestro planeta, está modificando fuertemente la disponibilidad de agua de calidad para amplios grupos de la población mundial. Las cianobacterias del fitoplancton juegan un papel muy relevante en la preservación de la calidad de las aguas (degradación de compuestos, reciclado de nutrientes…) pero además, algunos grupos de estos organismos pueden producir toxinas que provocan serios problemas se salud pública y ambiental. Las numerosas actividades humanas desarrolladas en las cuencas fluviales desde la Revolución Industrial, además de reducir la cantidad del caudal circulante de nuestros ríos, provocan la llegada de numerosos contaminantes que provocan severas alteraciones de la ecología de los ríos. Estos cambios afectan especialmente al fitoplancton, biofilms y bacterias. El objetivo de este trabajo ha sido estudiar el posible impacto de un pesticida, el lindano, sobre la producción de una de las cianotoxinas más ubicuas y abundantes, la microcistina. Para ello, se estudiaron los cambios inducidos por el pesticida en los niveles de RNA mensajero de genes responsables de la síntesis de la microcistina, operon mcy, genes reguladores de este operon y niveles de toxina producidos. El método utilizado para llevar a cabo este estudio fue la RT-PCR semicuantitativa por la que se cuantificó la expresión de los transcritos de los genes en diferentes condiciones, comparándolo con una muestra control. Como gen de referencia se utilizó el gen rrs. La cantidad de microcistina producida se determinó por el ensayo de inhibición de la proteín fosfatasa 2A. Con este estudio se pretende aportar datos que ayuden a poner en claro los efectos ocasionados por los lixiviados de lindano (que se producen periódicamente en los vertederos en que se depositaron los residuos de fabricación de este pesticida) en la población de cianobacterias y en la toxicidad de los blooms.

The development of new antiviral drugs against SARS-CoV-2 is a valuable long-term strategy to protect the global population from the COVID-19 pandemic complementary to the vaccination. Considering this, the viral main protease (M
pro ) is among the most promising molecular targets in light of its importance during the viral replication cycle. The natural flavonoid quercetin 1 has been recently reported to be a potent Mpro inhibitor in vitro, and we explored the effect produced by the introduction of organoselenium functionalities in this scaffold. In particular, we report here a new synthetic method to prepare previously inaccessible C-8 seleno-quercetin derivatives. By screening a small library of flavonols and flavone derivatives, we observed that some compounds inhibit the protease activity in vitro. For the first time, we demonstrate that quercetin (1) and 8-(p-tolylselenyl)quercetin (2d) block SARS-CoV-2 replication in infected cells at non-toxic concentrations, with an IC50 of 192 μM and 8 μM, respectively. Based on docking experiments driven by experimental evidence, we propose a non-covalent mechanism for Mpro inhibition in which a hydrogen bond between the selenium atom and Gln189 residue in the catalytic pocket could explain the higher Mpro activity of 2d and, as a result, its better antiviral profile.

ENDOSCOPIC ultrasonography ,PANCREATIC cysts ,LIQUIDS ,BIOPSY ,DIAGNOSIS - Abstract
Background: Current efforts in the identification of new biomarkers are directed towards an accurate differentiation between benign and premalignant cysts. Thermal Liquid Biopsy (TLB) has been previously applied to inflammatory and tumor diseases and could offer an interesting point of view in this type of pathology. Methods: In this work, twenty patients (12 males and 8 females, average ages 62) diagnosed with a pancreatic cyst benign (10) and premalignant (10) cyst lesions were recruited, and biological samples were obtained during the endoscopic ultrasonography procedure. Results: Proteomic content of cyst liquid samples was studied and several common proteins in the different groups were identified. TLB cyst liquid profiles reflected protein content. Also, TLB serum score was able to discriminate between healthy and cysts patients (71% sensitivity and 98% specificity) and between benign and premalignant cysts (75% sensitivity and 67% specificity). Conclusions: TLB analysis of plasmatic serum sample, a quick, simple and non-invasive technique that can be easily implemented, reports valuable information on the observed pancreatic lesion. These preliminary results set the basis for a larger study to refine TLB serum score and move closer to the clinical application of TLB providing useful information to the gastroenterologist during patient diagnosis.
