    A Comprehensive multiomics approach towards understanding obsessive-compulsive disorder 

    Domènech Salgado, Laura (Date of defense: 2018-12-20)

    To date, very little progress has been made towards elucidating the genetic causes of obsessive-compulsive disorder (OCD). In this project we have performed rare variant association study (RVAS) transcriptomics and ...

    A Comprehensive screening of X-linked and miRNA-driven signatures of positive selection and the role of cis-regulatory elements in the human genome 

    Villegas Mirón, Pablo (Date of defense: 2021-07-19)

    The evolutionary history of the human genome has been shaped by the selection of multiple elements in response to different environmental pressures. The analysis of regulatory adaptations and the particularities of sexual ...

    A Multivariate approach to study the genetic determinants of phenotypic traits 

    Garrido Martín, Diego (Date of defense: 2020-01-30)

    We have developed an efficient and reproducible pipeline for the identification of genetic variants affecting splicing (splicing quantitative trait loci or sQTLs), based on an approach that captures the intrinsically ...

    A system-level, molecular evolutionary analysis of mammalian phototransduction 

    Invergo, Brandon M. (Date of defense: 2013-11-22)

    Phototransduction is the biochemical process by which a light stimulus is converted to a neuronal signal. The process functions through complex interactions between many proteins, which work in concert to tightly control ...

    A Systems-level study of giant regulation in Drosophila melanogaster

    Adaptive history of the chimpanzee subspecies in the genomic era 

    Nye, Jessica (Date of defense: 2018-12-17)

    Although universal and unavoidable, aging does not occur in a uniform way. In this dissertation, we assessed the effects of early life exposure to pro-inflammatory risk factors (air pollution and obesity) on mitochondrial ...

    Addressing functional and evolutionary implications of microRNA variation at the DNA and RNA levels in primates 

    Gallego Jiménez, Alicia (Date of defense: 2016-11-14)

    microRNAs are small non-coding RNAs with crucial roles in gene regulation and whose contribution to animal evolution has been largely demonstrated. In this thesis we explored some functional consequences of microRNA sequence ...

    Alternative mechanisms of gene regulation during hematopoiesis 

    Ullrich, Sebastian (Date of defense: 2018-12-19)

    Gene regulation orchestrates the development of different cell types and organs from the same genetic blueprint. While the basic mode of gene regulation is driven by transcription factors, there are a variety of other ...

    An Integrative approach to the systematics and evolution of some selected reptile groups from Arabia 

    Simó Riudalbas , Marc (Date of defense: 2018-07-20)

    Until relatively recently, many groups of terrestrial reptiles were considered to contain only few species vastly distributed across the Arabian Peninsula. This was mostly the result of the apparent morphological uniformity ...

    Analysis of co-ancestry links in modern and ancient human populations 

    Ferrando-Bernal, Manuel (Date of defense: 2021-07-09)

    The aim of this thesis is to apply Identity by Descent (IBD) methodology to identify ancestry connections among individuals from genetically similar populations. Recombination events diminish the likelihood to detect IBDs. ...

    Analysis of genetic polymorphisms for statistical genomics: tools and applications 

    Morcillo Suárez, Carlos (Date of defense: 2011-12-19)

    New approaches are needed to manage and analyze the enormous quantity of biological data generated by modern technologies. Existing solutions are often fragmented and uncoordinated and, thus, they require considerable ...

    Analysis of genetic variation in microrna-mediated regulation and the susceptibility to anxiety disorders 

    Muiños Gimeno, Margarita (Date of defense: 2009-12-18)

    We have investigated genetic variation in microRNA-mediated regulation as a susceptibility factor for anxiety disorders following two different approaches. We first studied two isoforms of the candidate gene NTRK3 by ...

    Analysis of human genetic variation in candidate genes under positive selections on the human linage 

    Moreno Estrada, Andrés (Date of defense: 2009-04-21)

    Natural selection has played an important role in shaping human genetic variation, thus, finding variants that have been targeted by positive selection can provide insights about which genes influence human phenotypic ...

    Analysis of multiple protein sequence alignments and phylogenetic trees in the context of phylogenomics studies 

    Capella Gutiérrez, Salvador Jesús (Date of defense: 2012-11-16)

    Phylogenomics is a biological discipline which can be understood as the intersection of the fields of genomics and evolution. Its main focuses are the analyses of genomes through the evolutionary lens and the understanding ...

    Analysis of the evolving clinical phenotype and molecular mechanisms in Williams-Beuren syndrome 

    Palacios Verdú, María Gabriela (Date of defense: 2015-10-19)

    Williams-Beuren syndrome is a neurocognitive disorder with multisystemic manifestations of variable expressivity caused by a 1.55-1.83 Mb at chromosomal band 7q11.23. In this thesis project we have characterized the 7q11.23 ...
