Els tractaments actuals contra el càncer més enllà de la cirurgia inclouen teràpies que tenen un èxit limitat. Això és degut a efectes secundaris greus, que condueixen a una qualitat de vida reduïda i una baixa efectivitat. ...
López Escardó, David (Date of defense: 2018-01-15)
Opisthokonta is an eukaryotic supergroup that contains Metazoa, Fungi and their unicellular relatives. Therefore, this group provides an ideal framework to study distinct unicellular-multicellular transitions, among them, ...
López Begines, Santiago (Date of defense: 2016-11-18)
In photoreceptor cells of the retina, light triggers a protein G-mediated enzymatic cascade that leads to hydrolysis of cGMP. The drop in cGMP levels causes the closure of cGMP-channel at the plasma membrane, decreasing ...
Azagra Rodríguez, Alba (Date of defense: 2019-11-29)
B lymphopoiesis is the result of several cell lineage choices and differentiation steps whose perturbation leads to B cell malignancies. Cellular transitions for B cell generation have been associated with gene activation ...
