    Uncivering mechanisms of acquired resistance to trastuzumab-emtansine (T-DM1) in HER2 positive breast cancer 

    Sabbaghi Mehrjardi, Mohammad Ali (Date of defense: 2017-09-19)

    Trastuzumab-emtansine (T-DM1) is an antibody-cytotoxic agent (DM1) conjugated drug. DM1 delivery by trastuzumab inside the HER2 positive cells affects microtubule polymerization, cell cycle arrest and finally cell death. ...

    Uncovering the functional organization of molecular interaction networks using network embeddings based on graphlet topology 

    Tello Velasco, Daniel (Date of defense: 2023-09-19)

    [eng] For this purpose, Spatial Analysis of Functional Enrichment (SAFE) framework was proposed to uncover functional regions in a network by embedding it in 2-dimensions (2D) using the Spring embedding algorithm. However, ...

    Understanding chromosomal instability-induced senescence 

    Santos Tapia, Celia (Date of defense: 2019-10-30)

    Aneuploidy, defined as a chromosome number that deviates from a multiple of the haploid set, is a common feature in human cancer, and around 70% of human solid tumours are aneuploid. The resulting metabolic imbalance is ...

    Understanding stochastic and deterministric microbial assembly processes in ephemeral saline lakes 

    Menéndez Serra, Mateu (Date of defense: 2022-06-16)

    Understanding the mechanisms and processes driving biological com- munities assembly, i.e. determining why a specific community is found under certain circumstances, is one of the fundamental questions in ecology. The ...

    Understanding the link between chromatin structure, chromosome conformation and gene regulation 

    Buitrago Ospina, Diana Camila (Date of defense: 2019-12-16)

    Understanding the connection between DNA organization in the nucleus, and cell functioning is one of the most intriguing problems in biology. Although many interdisciplinary efforts have been developed for this aim, the ...

    Unravelling genetic predisposition to familial breast and ovarian cancer: new susceptibility genes and variant interpretation by in silico approaches 

    Moles Fernández, Alejandro (Date of defense: 2022-01-31)

    Patients with hereditary breast and ovarian cancer (HBOC) in whom a causative pathogenic variant is not identified after genetic analysis may not benefit from prevention, early detection, or precision treatment measures. ...

    Unveiling novel functions of the trascriptional repressor HDAC7 in B lymphocyte development 

    Azagra Rodríguez, Alba (Date of defense: 2019-11-29)

    B lymphopoiesis is the result of several cell lineage choices and differentiation steps whose perturbation leads to B cell malignancies. Cellular transitions for B cell generation have been associated with gene activation ...

    Unveiling the role of Slc7a7 in hematopoiesis 

    Giroud-Gernetant Deus, Judith (Date of defense: 2023-11-20)

    [eng] Lysinuric Protein Intolerance (LPI) is a rare autosomal recessive disorder caused by mutations in the SLC7A7 gene, which encodes the y+LAT1 transporter. LPI presents a pleiotropic phenotype that varies among patients, ...

    Uso de líneas celulares como modelos in vitro para la evaluación de toxicidad y mecanismos de acción de contaminantes ambientales 

    Pérez Albaladejo, Elisabet (Date of defense: 2017-09-18)

    En esta tesis se investiga la utilidad de diferentes bioensayos basados en el uso de líneas celulares (peces/humanas) y fracciones subcelulares, para la caracterización del riesgo ambiental que diversos contaminantes ...

    Variability in domain-scale regional mutation density across tissues and individuals 

    Salvadores Ferreiro, Marina (Date of defense: 2024-01-18)

    [eng] Mutations exhibit an uneven distribution across the human genome, with a regional mutation density (RMD) influenced by chromatin landscapes and replication timing. While there is a good understanding of this variation, ...

    β-cells cis-regulatory networks and type 1 diabetes 

    Ramos Rodríguez, Mireia (Date of defense: 2020-11-06)

    Type 1 Diabetes (T1D) is a ­cell­targeted autoimmune disease, leading to a reduction in pancreatic ­cell mass that renders patients insulin­dependent for life. In early stages of the disease, cells from the immune system ...
