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 ...
MERLIN: a novel BRET-based proximity biosensor for studying mitochondria–ER contact sites
(Life Science Alliance, 2020-01)
The contacts between the ER and mitochondria play a key role in cellular functions such as the exchange of lipids and calcium between both organelles, as well as in apoptosis and autophagy signaling. The molecular architecture ...
miR-27b Modulates Insulin Signaling in Hepatocytes by Regulating Insulin Receptor Expression
(MDPI, 2020-11-17)
Insulin resistance (IR) is one of the key contributing factors in the development of type 2 diabetes mellitus (T2DM). However, the molecular mechanisms leading to IR are still unclear. The implication of microRNAs (miRNAs) ...
