SARS-CoV-2 Infection Dysregulates the Metabolomic and Lipidomic Profiles of Serum

Óscar Millet

The lipidomic analysis unraveled a pathogenic redistribution of the lipoprotein particle size and composition to increase the atherosclerotic risk in COVID19 patients, consistent with a model in which SARS-CoV-2 infection induces liver damage associated with dyslipidemia and oxidative stress.

Characterization and Comprehensive Proteome Profiling of Exosomes Secreted by Hepatocytes

Juan Manuel Falcón

Exosomal membrane proteins as interesting tool to express nonexosomal proteins into exosomes with therapeutic purposes.

Detection of amyloid fibrils in Parkinson’s disease using plasmonic chirality

Joaquín Castilla

This report shows the use of protein fibrils as templates for chiral nanoparticle assembly and development of a biodetection technique, to identify patients with Parkinson’s disease from human brain homogenates.

Metabolomic Identification of Subtypes of Nonalcoholic Steatohepatitis

José M Mato

We identified specific panels of markers that could distinguish patients with NASH from patients with simple steatosis for each subtype of NAFLD.

Sox2 promotes tamoxifen resistance in breast cancer cells

María Vivanco

Development of tamoxifen resistance is driven by Sox2‐dependent activation of Wnt signalling in cancer stem/progenitor cells.

Catching elusive glycosyl cations in a condensed phase with HF/SbF5 superacid

Jiménez B, Jesús

Use of liquid hydrofluoric acid-antimony pentafluoride (HF/SbF5) superacid to generate and stabilize the glycosyl cations derived from peracetylated 2-deoxy and 2-bromoglucopyranose in a condensed phase.

Obesity-Dependent Metabolic Signatures Associated with Nonalcoholic Fatty Liver Disease Progression

José M Mato

BMI-dependent serum metabolic profile may be able to reliably distinguish NASH from steatosis patients, have significant implications for the development of NASH biomarkers.

Structure of ratcheted ribosomes with tRNAs in hybrid states

Mikel Valle

During protein synthesis, the displacement of the A-site tRNA on the 50S subunit is passive and is induced by the 30S subunit rotation, catalyzed by elongation factor G.

Wnt-11 promotes neuroendocrine-like differentiation, survival and migration of prostate cancer cells

Robert Kypta

Increased level of Wnt-11 found in prostate cancer contributes to tumour progression by promoting NED, tumour cell survival and cell migration/invasion.

Liquid Chromatography-Mass Spectrometry-Based Parallel Metabolic Profiling of Human and Mouse Model Serum Reveals Putative Biomarkers Associated with the Progression of Nonalcoholic Fatty Liver Disease

José M Mato

Metabolic phenotyping approach may have a future role as a supplement for clinical decision making in NAFLD and in the adaption to more individualized treatment protocols.

Evolution of Complex RNA Polymerases: The Complete Archaeal RNA Polymerase Structure

Nicola Abrescia

The archaeal RNA polymerase (RNAP) shares structural similarities with eukaryotic RNAP II and we have determined the structure of the 13-subunit DNA-directed RNAP from Sulfolobus shibatae at 3.35 Å resolution.

Structural Basis for the Aminoacid Composition of Proteins from Halophilic Archea

Óscar Millet

We show that it is possible to decrease the salt dependence of a typical halophilic protein to the level of a mesophilic form and engineer a protein from a mesophilic organism into an obligate halophilic form.

Regulation of prostate cell growth and morphogenesis by Dickkopf-3

Robert Kypta

Loss of Dkk-3 expression resulting in impairment of glandular structure and uncontrolled prostate epithelial cell (PrEC) proliferation, both of which are crucial for prostate cancer progression.
