Molecular pathways regulated by the ETV5 transcription factor in the invasion of endometrial cancer
El càncer d’endometri és la malaltia més freqüent del tracte genital femení en països desenvolupats. L’aparició de símptomes en estadis primerencs [1], contribueix a la detecció de la malaltia en estadis no avançats i amb ...
Molecular phocatodes and photoanodes for light driven water splitting
La fotosíntesis artificial és un procés on una molècula d’aigua es transforma en oxigen i hidrogen gas. Aquest procés permet obtenir combustibles solars (hidrogen gas) a partir d’aigua i llum solar i és una metodologia ...
Molecular physiology of a teleost oocyte aquaporin: evolution, regulation and role during oocyte hydration / Fisiología molecular de una acuaporina ovocitaria de teleósteos: Evolución, regulación y papel durante la hidratación del oocito
In marine teleosts that spawn pelagic eggs (pelagophils), the process of oocyte hydration that occurs during meiosis resumption is a key physiological process for the survival of the eggs in the ocean. Previous studies ...
Molecular quantum similarity in QSAR: applications in computer-aided molecular design
La present tesi està centrada en l'ús de la Teoria de Semblança Quàntica per a calcular descriptors moleculars. Aquests descriptors s'utilitzen com a paràmetres estructurals per a derivar correlacions entre l'estructura i ...
Molecular recognition and chemical space navigation in drug discovery
Efficient discovery of bioactive molecules is an essential goal of Computer-Aided Drug Design (CADD). The molecules can be used as chemical probes, to validate novel targets, or as starting points for drug discovery. ...
Molecular recognition in gas phase: theoretical and experimental study of non-covalent protein-ligand complexes by mass-spectrometry
In the present thesis we have explored different factors that impede accurate quantitative description of non-covalent protein-protein and protein-ligand interactions and design of new potent and specific binders from the ...
Molecular regulation of carotenoid biosynthesis in tomato fruits. New biotechnological strategies
Los carotenoides son metabolitos isoprenoides de gran relevancia económica como pigmentos naturales y fitonutrientes. Durante la maduración del fruto de tomate (Solanum lycopersicum) se acumulan niveles elevados de ...
molecular regulation of the immune function in the gills of gilthead sea bream (sparus aurata) fed with immunostimulant diets
En los últimos 10 años, diferentes inmunoestimulantes han sido probados en más de 18 especies de peces, incluyendo carpa, turbot, salmón del atlántico, dorada, trucha, entre otros. Los compuestos que han sido estudiados ...
Molecular retention mechanisms of the G1 cyclin/Cdk complex in budding yeast
Budding yeast (Saccharomyces cerevisiae) cells coordinate cell growth and cell cycle progression essentially during G1, where they must reach a critical cell size to traverse Start and enter the cell cycle. The most upstream ...
Molecular segregation at multiple scales in perylene-based systems for the preparation advanced materials
[eng] This thesis addresses molecular segregation in perylene-based systems, including lyotropic chromonic liquid crystals and water-in-water emulsions. These systems offer several advantages compared to conventional ...
