Despite decades of work, the molecular requirements underlying microtubule- organizing center (MTOC) formation at the centrosome remain obscure. Progress is hindered by the complexity of this organelle, which is composed ...
The main goal of this thesis was to investigate the function of the endogenous CD300f. Initially, CD300f was described as an inhibitory receptor, although some data generated in our lab strongly suggested the possibility ...
[eng] BACKGROUND: High-risk neuroblastoma (NB) represents a heterogeneous group of tumors, whereby patients can display response to treatment and long-term outcome or develop early progressive, chemoresistant disease with ...
Epigenetic factors, such as histone post-translational modifications and DNA methylation, are critical determinants of gene expression, which ultimately defines cell identity and function. Despite intense research in DNA ...
During the process of corticogenesis, cortical radial glial cells (RGs) generate sequentially most of the distinct types of neurons and glial cells that will populate the neocortex. The generation of these cells at the ...
La presente Tesis Doctoral está centrada en el centollo atlántico (Maja brachydactyla Balss, 1922). Los objetivos incluyen la optimización del cultivo larvario y el estudio ontogénico del sistema digestivo. El cultivo ...
The study of morphology of organisms has become a widely extended scientific discipline since the beginning of the 20th century, when the scientific community began to establish direct relationships between the anatomical ...
Breast cancer is a very heterogeneous disease with a poor prognostic outcome, largely due to its resistance to current cancer therapies. The balance between cell proliferation and apoptosis plays a critical role in determining ...
[eng] In the quest for understanding complex biological systems, the scientific community has been delving into protein, chemical and disease biology, populating biomedical databases with a wealth of data and knowledge. ...
[eng] BACKGROUND: Low-density lipoprotein receptor-related protein 1 (LRP1) plays a key role in fatty acid metabolism and glucose homeostasis. In the context of dyslipidemia, LRP1 is positively regulated in the heart. The ...
Els trastorns neuromusculars pediàtrics són malalties minoritàries causades per un gran nombre de gens, molts d’ells de gran mida i d’estructura complexa, fet que dificulta enormement el diagnòstic molecular i el disseny ...
[eng] Tumour progression largely depends on the signalling networks that direct cell viability, growth and dissemination (metastasis). Transforming growth factor beta (TGF-β) and Bone Morphogenetic Protein (BMP) are cytokines ...
The nucleosome is the fundamental structural unit of DNA compaction in eukaryotic cells and is formed by the wrapping of 147 bp double stranded DNA around a histone octamer. Nucleosome organization plays a major role in ...
This thesis presents a broad study of the chromatin structure and function with special focus in the nucleosome organization. More specifically, it includes three different but complementary perspectives: i) Analysis of ...
La peste porcina africana (PPA) es una enfermedad hemorrágica altamente infecciosa que afecta principalmente a cerdos domésticos, causando verdaderos estragos en la producción porcina en los países afectados. El agente ...
Es coneix que la nutrició en les primeres etapes de la vida és un factor clau que contribueix a la prevalença de la obesitat, així com la resta de característiques de la Síndrome Metabòlica en l’edat adulta (Langley-Evans ...
Se ha demostrado en un número de estudios de metagenómica que la adición y la pérdida de genes específicos ha permitido a los microbiomas adaptarse a condiciones ambientales típicas de los entornos. Pero, aún no se conoce ...
El colágeno VI es una proteína de la matriz extracelular cuyos defectos conducen a una variedad de trastornos musculares en humanos caracterizados por una debilidad muscular entre otros múltiples síntomas. Tanto el colágeno ...
A pesar de las extensas investigaciones durante las últimas décadas, la pancreatitis aguda (PA) continúa siendo un reto para el manejo clínico, con una importante carga de morbilidad, mortalidad y coste, cuando la enfermedad ...
La proteïna secretada Apoptosis inhibitor expressed by macrophages (AIM) és expressada per macròfags tissulars en condicions d’inflamació. És una glicoproteïna que pertany a la família dels Receptors Scavenger Rics en ...
