Las enfermedades cardiovasculares son la primera causa de muerte en todo el mundo y representan uno de los desafíos primordiales en la investigación biomédica. La aterosclerosis es causante de la mayoría de las enfermedades ...
Sphingolipids (SLs), essential components of cell membranes, are bioactive molecules involved in the regulation of a variety of cellular processes. Ceramide and sphingosine generally mediate anti-proliferative stimuli, ...
Ischemia-reperfusion injury (IRI) is an inevitable situation in clinical settings such as liver transplantation and hepatic resection. It develops when blood flow is interrupted for a long period of time (ischemia) and ...
Antiangiogenic drugs are used clinically for treatment of different types of cancers and in the case of renal cell carcinoma (RCC) are now standard first-line treatments (Rini, 2009). Nevertheless, these agents mainly serve ...
Amyotrophic lateral sclerosis (ALS) and frontotemporal lobar degeneration (FTLD) are clinically distinct neurodegenerative diseases that are connected by genetic and pathological overlap. ALS patients present with muscle ...
The microtubule cytoskeleton plays essential roles during cell division, migration, differentiation, defining cell morphology and organizing intracellular transport. The properties of microtubules, such as their stability, ...
Las modificaciones moleculares que constituyen el objetivo de la presente Tesis pretenden aportar nuevos datos que permitan un más amplio conocimiento de los requisitos estructurales y estereoquímicos necesarios tanto ...
Cardiovascular diseases (CVD) are the principal cause of mortality worldwide. Lifestyle plays a crucial role in preventing the development of CVD, and one of its key elements is diet, which directly affects cardiometabolic ...
In this thesis the role of cyclic AMP , the endoplasmic reticulum stress and adipocytokines such as adiponectin, resistin and visfatin injury in I/R in steatotic liver grafts and non- steatotic undergoing transplantation ...
Las alteraciones del metabolismo lipídico causadas por la isquemia miocárdica tienen profundos efectos en el estado fisiológico del corazón. En el corazón isquémico, la hipoxia incrementa la formación de vacuolas lipídicas ...
La cromatina és una estructura nucleoproteica, dinàmica i jeràrquicament organitzada dins del nucli cel•Iular. La seva estructura, organització i funció està controlada al llarg del cicle cel.lular, per processos epigenètics ...
El neuroblastoma (NB) agrupa un espectro muy heterogéneo de tumores que evolucionan de forma radicalmente distinta. La variedad de comportamiento clínico del NB determina el enfoque terapéutico, que puede variar entre un ...
El estudio de los gamma-péptidos miméticos basados en cis-gamma-amino-L-prolina con capacidad de atravesar la membrana celular en diferentes organismos, constituye una temática de gran interés en el área de biomedicina ...
Optical tools to control neuronal activity include synthetic photoswitchable ligands of receptors and ion channels. Photoswitches can act either as soluble molecules (photochromic ligands, PCLs) or tethered to the protein ...
One of the ultimate goals in biomedicine is to understand the relationship between structure, function, and dynamics of biomolecules in living cells. The biophysical tools designed to gain more insight into metabolism, ...
Cytoplasmic polyadenylation element binding proteins (CPEBs) are a family of RNA-binding proteins essential for the translational regulation of mRNAs in various biological contexts. CPEBs recognize CPE elements in the 3’ ...
Proteins are the embodiment of the message encoded in the genes and they act as the building blocks and effector part of the cell. From gene regulation to cell signalling, as well as cell recognition and movement, ...
La adenosina es un metabolito presente en todo el organismo con distintas funciones fisiológicas. En el sistema nervioso central, desempeña un importante papel como neuromodulador a través de la interacción con sus receptores ...
Within the hematopoietic system, all mature blood cells are generated. Every differentiation step is characterized by the activation of a new, lineage specific, genetic program and the extinction of the previous one. To ...
In normal epithelial cells, p38α has a well-established role as a tumor suppressor. However, recent reports have illustrated pro-tumorigenic functions for the p38α pathway by promoting tumor cell survival and proliferation. ...
