[cat] Un dels pilars bàsics que componen la raó de ser dels parcs zoològics actuals és la conservació ex situ d’espècies amenaçades. Aquesta comesa, comporta el compliment d’una sèrie de requisits, entre ells, el de ...
Fernández Pineda, Alejandra (Date of defense: 2017-12-12)
El establecimiento de conexiones sinápticas específicas entre neuronas es esencial para la formación de los circuitos neuronales. En muchos sistemas esto requiere de una extensión hacia una capa sináptica concreta y la ...
Calvo Martín, Juan Manuel (Date of defense: 2017-07-21)
Las proteínas codificadas por los genes del grupo Polycomb (PcG) constituyen un sistema clave de silenciamiento epigenético. Actúan en forma de complejos multiproteicos y modulan el estado de la cromatina mediante ...
Escuer Pifarré, Paula (Date of defense: 2022-12-21)
[eng] During the last decade, advances in high-throughput sequencing (HTS) technologies have increased exponentially the generation of genomic data, especially of non-model species. In this thesis, we generated and used ...
Ferrer Obiol, Joan (Date of defense: 2021-03-19)
How populations differentiate and become new species is a foundational question to the field of evolutionary biology and has important implications for the generation of both local and global patterns of species-level ...
Burguera Hernández, Demian (Date of defense: 2017-09-22)
In the present work, we studied the evolution of alternative splicing (AS) from different perspectives. First, we performed a preliminary analysis where we identified alternative exons with tissue-specific regulation in ...
Aísa Marín, Izarbe (Date of defense: 2022-05-13)
The transcription factor NR2E3 participates in photoreceptor cell fate determination as it functions as both transcriptional repressor of cone genes and activator of rod genes. Mutations in NR2E3 cause retinitis pigmentosa ...
