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 ...
Baía, Diogo Nogueira de Graça (Date of defense: 2014-10-24)
In the present work the regulatory role played by the HLA class I (HLA-I)-specific LILRB1 inhibitory receptor in human macrophages (MΦ) was addressed. In vitro differentiated monocyte-derived M1 and M2 MΦ expressed different ...
Fraile Beneitez, Rodrigo (Date of defense: 2021-07-23)
Eukaryotic DNA is condensed inside the nucleus, compacted into chromatin. The structure of chromatin is dynamic, and its accessibility to cellular machinery can be altered depending on the level of chromatin compaction ...
Marte, Luis (Date of defense: 2020-01-31)
Proteostasis is the proper homeostasis of the concentration and the molecular structure of the proteins, which preserves the integrity of the proteome. Proteo-stasis is constantly challenged by intrinsic and extrinsic ...
Carcolé Estrada, Mireia (Date of defense: 2019-12-05)
Osteoarthritis is the most common musculoskeletal disease worldwide, characterized by degradation of the articular cartilage, chronic joint pain and disability. Currently available treatments for osteoarthritis have limited ...
Dasti, Alessandro (Date of defense: 2020-01-22)
The molecular basis that sustain embryonic stem cell (ESCs) pluripotency and their differentiation in all the types of somatic cells is subject of intensive research. Recently, the potential involvement of RNA Binding ...
Sansó Martínez, Miriam (Date of defense: 2010-07-02)
In Schizosaccharomyces pombe, the MAPK pathway Sty1 is activated upon several stress situations, like osmotic and oxidative stress, stationary phase, UV radiation or heat shock. Since the modulation of gene expression is ...
Drews-Elger, Katherine (Date of defense: 2008-11-07)
The transcription factor NFAT5/TonEBP belongs to the Rel family, which also comprises NF ÛB and NFATc proteins. NFAT5 only shares structural and functional homology with other Rel family members at the level of the DNA ...
Yáñez Bisbe, Laia (Date of defense: 2022-02-25)
Els mecanismes que determinen el desenvolupament de remodelat cardíac, tant en la seva forma adversa (característica de la insuficiència cardíaca), com adaptativa (induïda per exercici), no es coneixen en detall. Els ...
Khatri, Safia (Date of defense: 2009-03-23)
En els darrers anys s'ha produït un gran avenç en l'enteniment dels mecanismes implicats en la inducció de la placoda òtica. Tanmateix, poc es coneix encara de com s'estableix un domini amb competència neural i un altre ...
Farnós Amorós, Esther (Date of defense: 2010-05-05)
La tesi doctoral "Ruptura del projecte parental i disposició dels preembrions" analitza els efectes del consentiment a les tècniques de reproducció assistida prestat en el marc d'un projecte parental. La tesi ofereix una ...
