In this Thesis we report the successful growth of hormone responsive T47D cells as 3D spheroids in Matrigel mimicking the ECM. A detailed characterization by using a genome-wide approach of the main physical and biochemical ...
Lsm proteins regulate RNA metabolism and are conserved in the three domains of life, typically functioning as RNA-binding complexes involved in a wide range of post-transcriptional mechanisms. Generally, their functions ...
Partitioning of chromatids during mitosis requires that chromosome compaction and spindle length scale appropriately with each other. However, it is not clear whether chromosome condensation and spindle elongation ...
X-linked adrenoleukodystrophy (X-ALD) is an inherited neurodegenerative disorder. The genetic bases for all its different phenotypic variants are mutation in the gene encoding the peroxisomal ATP-binding cassette (ABC) ...
Alternative splicing (AS) is a mechanism of post-transcriptional regulation that plays an important role during development and in the maintenance of stem cell pluripotency. The dynamics of AS regulation during somatic ...
Los objetivos de este trabajo han sido estudiar la expresión de receptores de células NK (NKR), en particular CD94/NKG2C, en relación con la infección por citomegalovirus humano (HCMV). Los resultados descritos constituyen ...
En aquesta tesi hem intentat atacar preguntes relacionades amb els orígens de la vida multicel•lular i dels comportaments cooperatius a la nostra biosfera. Particularment hem fet ús de mètodes “no naturals”: la vida ...
Aurora A (AurA) is an important mitotic kinase mainly studied for its involvement in cell cycle progression, centrosome maturation, mitotic spindle pole organization and bipolar spindle formation. It localizes to ...
The spleen contains a unique subset of innate-like marginal zone (MZ) B cells that rapidly mount protective antibody responses to invasive encapsulated bacteria. Here we show that human splenic MZ B cells also mount ...
Cellular errors can spontaneously occur during vertebrate embryo development and can lead to apoptosis. Recent work in our lab revealed a novel function of the embryonic epithelium as an efficient phagocytic scavenger of ...
Continuous C/EBPa expression converts B cells into macrophages while its transient upregulation before the Yamanaka factors yields highly efficient iPSC reprogramming. C/EBP members regulate Il6 pathway genes and IL-6 ...
One of the major goals of current stem cell research is understanding the mechanism of somatic cell reprogramming by Oct4, Sox2, Klf4 and Myc (OSKM) into induced pluripotent stem cells (iPSCs). However, the finding ...
El càncer de pàncrees és altament agressiu i representa la cinquena causa de mort al mon occidental. Anteriorment, en el nostre laboratori, vam identificar que el receptor tissular del plasminogen (tPA) hi està sobre-expressat ...
Human cytomegalovirus (HCMV) infection induces a persistent reconfiguration of the NK cell compartment in some individuals, promoting the development of a mature NK cell subset, hallmarked by high expression levels of ...
Notch activation in aortic endothelial cells (ECs) takes place at embryonic stages during cardiac valve formation and induces an endothelial-to-mesenchymal transition (EndMT). Using aortic ECs, we show here that active ...
S'ha establert un sistema experimental autòleg per a poder estudiar la resposta de les cèl.lules Natural Killer (NK) contra les cèl.lules dendrítiques derivades de monòcits (moDC), infectades pel Cytomegalovirus humà (HCMV). ...
The product of the snail1 gene (SNAIL1) is a transcriptional repressor required for triggering the epithelial-to-mesenchymal transition (EMT). SNAIL1 transcription is induced when epithelial cells are forced to acquire a ...
Cancer cells exhibit a synthetic lethal (SL) phenotype when Myc upregulation is combined with antitumor drugs targeting the splicing factor SF3B1. However, the molecular events and mechanisms responsible for this vulnerability ...
La arquitectura del genoma y la estructura de la cromatina, junto con los factores de transcripción son actores clave para la autorenovación, la pluripotencia y la diferenciación de las células madre embrionarias (ESCs). ...
Les làmines nuclears (A/C i B) són els majors constituents de la làmina nuclear (NL). Els estructuralment conservats dominis associats a les làmines (LADs) estan formats per regions genòmiques que contacten amb la NL. Tot ...
