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 ...
A Computational Module Assembled from Different Protease Family Motifs Identifies PI PLC from Bacillus cereus as a Putative Prolyl Peptidase with a Serine Protease Scaffold
(Public Library Science, 2013-08)
Proteolytic enzymes have evolved several mechanisms to cleave peptide bonds. These distinct types have been systematically categorized in the MEROPS database. While a BLAST search on these proteases identifies homologous ...
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 ...
The Myth of The Annular Lipids
(MDPI, 2022-10-22)
In the early 1970s, the existence of a “lipid annulus” stably surrounding the individual intrinsic protein molecules was proposed by several authors. They referred to a number of lipid molecules in slow exchange with the ...
Arachidyl Amido Cholanoic Acid Improves Liver Glucose and Lipid Homeostasis in Nonalcoholic Steatohepatitis Via AMPK and mTOR Regulation
(Baishideng, 2020-09-14)
BACKGROUND Arachidyl amido cholanoic acid (Aramchol) is a potent downregulator of hepatic stearoyl-CoA desaturase 1 (SCD1) protein expression that reduces liver triglycerides and fibrosis in animal models of steatohepatitis. ...
Birth and Early Steps of the Organization of Biophysics in Spain
(MDPI, 2022-11-19)
In the 1960s, Biophysics was an unheard of scientific field in Spain, and even outside Spain, the distinction between Biophysics and Molecular Biology was not clear at the time. This paper describes briefly the developments ...
Adenylate Cyclase Toxin promotes bacterial internalisation into non phagocytic cells
(Nature Publishing Group, 2015-09-08)
Bordetella pertussis causes whooping cough, a respiratory infectious disease that is the fifth largest cause of vaccine-preventable death in infants. Though historically considered an extracellular pathogen, this bacterium ...
Sphingomyelin: What is it good for?
(Elsevier, 2022-12)
Sphingomyelin has been considered as a merely structural lipid for many years. However, this organelle-specific lipid has many other roles, including increasing membrane molecular order, acting as a source of ceramide in ...
Membrane lipid modifications and therapeutic effects mediated by hydroxydocosahexaenoic acid on Alzheimer's disease
(Elsevier, 2013-12-27)
[EN] Alzheimer's disease (AD) is a neurodegenerative pathology with relevant unmet therapeutic needs. Both natural aging and AD have been associated with a significant decline in the omega-3 polyunsaturated fatty acid ...
Ceramide-enriched membrane domains in red blood cells and the mechanism of sphingomyelinase-induced hot-cold haemolysis
(American Chemical Society, 2008-10-28)
Hot-cold hemolysis is the phenomenon whereby red blood cells, preincubated at 37 °C in
the presence of certain agents, undergo rapid hemolysis when transferred to 4 °C. The mechanism of this
phenomenon is not understood. ...
