Identificación of ERBB4 and SOX1 role in central nervous system tumors. Implication in medulloblastoma and glioblastoma.
(2020-12-16)
Los tumores cerebrales, como el glioblastoma (GBM) en adultos y el meduloblastoma (MB) en niños, representan uno de los retos más importantes de la medicina actual, ya que resisten a las terapias disponibles, recurren y ...
Structural Characterization of the ICOS/ICOS-L Immune Complex Reveals High Molecular Mimicry by Therapeutic Antibodies
(Nature, 2020-10-08)
The inducible co-stimulator (ICOS) is a member of the CD28/B7 superfamily, and delivers a positive co-stimulatory signal to activated T cells upon binding to its ligand (ICOS-L). Dysregulation of this pathway has been ...
Characterization of the biological and molecular activity of PML in breast cancer
(2020-11-23)
Oncogene addiction postulates that the survival and growth of certain tumor cells is dependent upon the activity of one oncogene, despite their multiple genetic and epigenetic abnormalities. This phenomenon provides a ...
Unveiling the activation dynamics of a fold-switch bacterial glycosyltransferase by 19F NMR
(American Society for Biochemistry and Molecular Biology, 2020-07-17)
Fold-switch pathways remodel the secondary structure topology of proteins in response to the cellular environment. It is a major challenge to understand the dynamics of these folding processes. Here, we conducted an in-depth ...
Microfluidic chip with pillar arrays for controlled production and observation of lipid membrane nanotubes
(Royal Society of Chemistry, 2020-08-07)
Lipid membrane nanotubes (NTs) are a widespread template forin vitrostudies of cellular processes happening at high membrane curvature. Traditionally NTs are manufactured one by one, using sophisticated membrane ...
A fluorogenic cyclic peptide for imaging and quantification of drug-induced apoptosis
(Nature, 2020-08-12)
Programmed cell death or apoptosis is a central biological process that is dysregulated in many diseases, including inflammatory conditions and cancer. The detection and quantification of apoptotic cells in vivo is hampered ...
Determinación estructural de virus con envuelta lipída mediante crio-microscopía electrónica.
(2020-02-10)
Viruses are parasitic biological agents that in the virion state contain differentmorphologies and assembly organisations. In some virions, a lipid membrane of cellularorigin is a structural component of the infectious ...
Searching for biomarkers of non-alcoholic fatty liver disease and metabolic syndrome
(2020-05-29)
El desarrollo de esta tesis doctoral ha aportado luz sobre los mecanismos que subyacen a la enfermedad del hígado graso no alcohólico (NAFLD por sus siglas en inglés), ya que los resultados han revelado la existencia de ...
The Golgi as an Assembly Line to the Autophagosome
(Elsevier, 2020-06)
Autophagy is traditionally depicted as a signaling cascade that culminates in the formation of an autophagosome that degrades cellular cargo. However, recent studies have identified myriad pathways and cellular organelles ...
Photoacoustic effect applied on model membranes and living cells: direct observation with multiphoton excitation microscopy and long-term viability analysis
(Nature, 2020-01-15)
The photoacoustic effect is generated when a variable light interacts with a strongly light-absorbing material. In water, it may produce hot bubbles and shock waves that could affect the integrity of nearby cellular ...
