Huidobro Torres, Alba (Date of defense: 2022-07-15)
This Ph.D. dissertation examines the extent to which the personal characteristics of political leaders affect their political ambition and government formation processes. While the literature shows that government ...
Sancho Medina, Mònica (Date of defense: 2008-05-30)
At least eleven histone H1 variants exist in mammalian somatic cells that bind to the linker DNA and stabilize the nucleosome particle contributing to higher order chromatin compaction. In addition of playing a structural ...
Hurtado-Bagès, Sarah (Date of defense: 2019-09-27)
In the eukaryotic nucleus, DNA, wrapped around a core of histone proteins. Replication-coupled histones can be exchanged by histone variants. In mammals, H2A can be replaced by three distinct macroH2A proteins. Alternative ...
Suades Soler, Rosa (Date of defense: 2014-11-21)
Cardiovascular disease and, specifically, atherothrombosis is a global health problem with huge devastating consequences. While cardiovascular research has progressed rapidly over the last years, there is still a need ...
Gentile, Maurizio (Date of defense: 2014-09-19)
The marginal zone (MZ) of the spleen contains an innate-like subset of B cells that mount rapid protective antibody responses to polysaccharides and lipids from bloodborne viruses and bacteria. These antigens activate ...
Pich Roselló, Oriol (Date of defense: 2021-03-24)
Cells of our body are constantly exposed to events that can create lesions in the DNA. If unremoved by the DNA repair mechanisms, the lesion may lead to a mutational event. Some of these events might drive the transformation ...
Güney, Emre (Date of defense: 2012-09-25)
The cell is governed by the complex interactions among various types of biomolecules. Coupled with environmental factors, variations in DNA can cause alterations in normal gene function and lead to a disease condition. ...
Tellechea Recarte, Mónica (Date of defense: 2017-05-19)
Macrophages are exquisite sensors of tissue homeostasis that can rapidly switch between pro- and anti-inflammatory or regulatory modes to respond to perturbations in the microenvironment. This functional plasticity involves ...
Cabo, Mariona (Date of defense: 2019-11-08)
HER2 overexpression accounts for approximately 15-20% of breast tumors, and mainstay therapy for these patients includes HER2-specific antibodies in combination with chemotherapy. Although the efficacy of anti-HER2 antibodies ...
Amador Arjona, Alejandro (Date of defense: 2008-07-23)
The correct development and function of CNS is critical for brain health of the organism. Early or chronic stress causes prominent alterations in brain function, and affects the expression of neurotrophic factors in limbic ...
Wierer, Michael (Date of defense: 2013-01-13)
Steroid receptors (SRs) are hormone-induced transcription factors that regulate gene expression by their concerted actions with coregulatory proteins. Performing a quantitative mass spectrometry-based interaction screen ...
Condemi, Livia (Date of defense: 2024-03-07)
Polycomb repressive complex (PRC) 2 is one of the key regulators of the transcriptional programs, it maintains stem cell properties and guides cell lineage specification. It is a multiprotein complex formed by a core and ...
Chammas, Paul (Date of defense: 2019-11-29)
Polycomb repressive complex 2 (PRC2) is a key epigenetic regulator of gene expression. It acts through its histone-modifying activity, as it is responsible of di- and trimethylating the tail of histone H3 on lysine 27 ...
Cassis, Linda (Date of defense: 2015-10-29)
Human spleen is continually exposed to blood-borne antigens derived from autologous apoptotic cells and commensal bacteria. This chronic stimulation of the marginal zone (MZ) results in the generation of a steady-state ...
Vargas-Prada Figueroa, Sergio (Date of defense: 2014-01-24)
This PhD thesis is based on the Spanish sample of the International “Cultural and Psychosocial Influences on Disability” (CUPID) study. This multicentre study is coordinated by Professor David Coggon at the University of ...
Mòdol Cano, Aitor (Date of defense: 2021-04-29)
El cilio primario es una estructura formada por microtúbulos que sobresale de la superficie celular durante G0 teniendo una función de orgánulo sensor. La importancia del cilio es patente por las ciliopatías como la ...
Bosch Gutiérrez, Almudena (Date of defense: 2009-12-21)
The Polycomb group (PcG) family of proteins form chromatin-modifying complexes essential for embryonic development, and stem cell renewal and are commonly deregulated in cancer. There are several reports that address the ...
Quevedo Díaz, Marcos (Date of defense: 2017-12-21)
Understanding the neural basis of conscious perception is still one of the central unsolved problems in neuroscience. Current theoretical models of conscious processing include the Global Workspace Theory, that proposes ...
Galão, Rui Pedro Ribeiro (Date of defense: 2010-12-01)
By using the ability of the positive-strand RNA ((+)RNA) virus BMV to replicate in yeast it was previously shown that subunits of the LSm1-7 ring, as well as Pat1 and Dhh1 play an essential role in the transit of the BMV ...
Cutando Ruiz, Laura (Date of defense: 2015-07-17)
The endocannabinoid system is an endogenous neuromodulatory system widely expressed in the central nervous system. It modulates synaptic plasticity and neuronal excitability, and fine-tunes several physiological functions ...
