Verd Fernández, Berta (Date of defense: 2016-01-21)
During insect development segments either form sequentially (short-germband) or simultaneously (long-germband) . The gap genes comprise the first zygotic regulatory layer of the segmentation gene hierarchy in flies, which ...
Cirera, Eva (Date of defense: 2014-10-17)
Les lesions traumàtiques en la gent gran són un problema de salut pública important, donat que són una de les principals causes de morbiditat en aquest col·lectiu. L’estudi de la incidència de lesions en la gent gran i ...

En aquest treball es presenta l'evolució molecular i estudi funcional de gens localitzats a les duplicacions segmentàries de la regió 7q11.23, implicada en la Síndrome de Williams-Beuren (SWB). S'ha datat l'aparició ...
Rodríguez Sanz, Maica (Date of defense: 2017-12-21)
El objetivo es analizar la evolución de las desigualdades socioeconómicas en mortalidad en los barrios de Barcelona, considerando los cambios poblacionales ocurridos. Se realizaron 3 estudios. Una revisión del uso del ...
Brasó-Vives, Marina (Date of defense: 2019-01-18)
La duplicació és el principal mecanisme de formació de nou material genètic i d'innovació funcional. Entendre com les duplicacions sorgeixen, evolucionen, co-evolucionen i engendren noves funcions és essencial. Aquesta ...
Sentís Carreras, Inés (Date of defense: 2021-01-22)
Acute lymphoblastic leukemia (ALL) is a blood cancer characterized by a high proliferation and maturation arrest of the lymphoid precursors which can either be from B or T-cell lineage. In adult patients, this type of ...
Bello, Carla (Date of defense: 2017-12-15)
La identificación de elementos funcionales en el genoma no-codificante continúa siendo una tarea desafiante. La genómica comparativa puede ayudarnos a entender como estos elementos han evolucionado y cuáles son sus ...
Ferrández Peral, Luis (Date of defense: 2022-06-08)
The evolution of transcriptomes has been linked to the emergence of novel phenotypes. However, our knowledge on how isoform diversity has impacted recent human evolution is very limited. To fill this gap, we have performed ...
Mantica, Federica (Date of defense: 2023-05-11)
Regulated Gene Expression (rGE) and Alternative Splicing (rAS) are two of the main mechanisms contributing to tissue-phenotypic diversity within and between species. In this thesis, we aim at characterizing rGE and rAS ...
Valles Ibáñez, Guillem de (Date of defense: 2016-11-16)
Human genomes have been found to harbor an unexpected number of ~100 loss-of-function (LoF) variants, with ~20 of them in an homozygous state, in most cases without a visible effect despite its potential truncation of ...
Blevins, William Robert (Date of defense: 2020-01-17)
All living organisms respond to environmental stimuli by modulating the activity of different genes. This response can occur across many locations throughout the cell such as at the level of transcription, translation, and ...
Gigli, Elena (Date of defense: 2011-06-20)
The evolutionary history of H. neanderthalensis, interwoven with that of H. sapiens, has always fascinated the scientific world. Recent adavncess in paleogenetics shedds new light on the phylogenetic relationship between ...

Una de les forces selectives més fortes que han afectat a les poblacions humanes en la història més recent és el paràsit de la malària: Plasmodium falciparum, que és la causa de varis exemples d'adaptació induïda per ...
Hernando Herráez, Irene (Date of defense: 2015-07-24)
DNA methylation is a crucial epigenetic modification involved in numerous biological processes. However, despite its functional importance, the evolutionary history of this modification and the mechanisms diving such changes ...
Esteller Cucala, Paula (Date of defense: 2023-04-18)
Changes in the epigenetic regulation of gene expression have important implications for evolution. However, the study of these changes (i) has not been consistently assessed across closely related species, (ii) oftentimes ...
García Pérez, Raquel (Date of defense: 2019-01-29)
The evolution of the human phenotype involved gene regulatory innovations. Comparative functional epigenomic studies are a powerful tool with potential to shed light on many long-standing questions regarding human evolution. ...
Gambetti, Luca (Date of defense: 2006-07-03)
The present thesis is a collection of three separate essays, each corresponding to a chapter.Each essay represents an application of structural dynamic analysis within TVC-VARmodels. In the first chapter, coauthored with ...
